Episode Transcript

Speaker 1 (00:06):
You're listening to the Resident Builder podcast with Peter Wolfcamp
from news Talks at b ment or twice god once
but maybe called Pete first.

Speaker 2 (00:16):
Peter wolf Camp, the Resident Builder News Talk said, b.

Speaker 3 (00:26):
The house sizzle even when it's dark, even when the
grass is overgrown in the yard, and even when a
dog is too old to barn, and when you're sitting.

Speaker 4 (00:42):
At the table trying to have to start house scissor home,
even when we are being even when you're there alone,

(01:05):
the houses along given when nes gone, even.

Speaker 3 (01:10):
When you go around from the ones you love your most.

Speaker 2 (01:15):
Scream broken pains, appearing in front of the.

Speaker 3 (01:20):
Locals vestable when they're going and leaving them.

Speaker 4 (01:24):
Has even when we'll be ben, even when you're in
there alone.

Speaker 5 (01:34):
Yeah, well, very good morning, and welcome along to the
Resident Builder on Sunday. Here we are August the twenty fourth.
The days are I'm not quite getting longer. It was
cold last night. It was cold in an old house
where I've done my best to insulate and all the

(01:57):
rest of it. But last night, ah, I was thinking
about all of the possibilities of a new build, all
of the possibilities of a deep red Trophit if your
house was warm, dry, comfortable, and that is what we
try and achieve on the show to get you to
think about ways to make your house perform better. What
things can you make changes to How could you potentially

(02:19):
build a new property and allow it to be warm, dry, comfortable,
not suck up great amounts of energy at this time
of year to keep it warm, to keep whatever precious
heat you've generated inside from escaping to the outside. That's
what we're ultimately talking about on the show.

Speaker 2 (02:37):
Good Morning.

Speaker 5 (02:37):
My name is Pete wolf Camp, the Resident Builder, and
this is an opportunity to talk all things building and construction.
It's the rules, the regulation, it's the materials, the products
that you can use. It's the people that you might
end up engaging with as well, working with subcontractors and tradees,
you know, picking basically, how not to pick a lemon

(03:00):
when you pick a trade And I say this respectfully
every now and then so often on this program, and
sometimes in sort of conversations out of it. I speak
with people who you know, opted for a trade to
come and do some work on their house and being disappointed.
Some people there's just no satisfying, but in other cases

(03:21):
you just see cases where people are just actually not
that great at their job, So how do you avoid that?
And then there's there's the rules, the regulations, there's the products,
there's the people, and then there's your own choices about
you know, where do you spend your money? If you're
doing a renovation, what are you going to focus on?
Is it the size of it, is it the performance

(03:41):
of it, is it a look of it? Or is
there a balance of all three? So that's what we're
talking about today on the show, as we do every
Sunday morning.

Speaker 2 (03:50):
And I welcome you in.

Speaker 5 (03:51):
Great to have your company, and great to know that
you're out there and hopefully not quite as chilly as
my place was overnight. Not I mean, look, it's Auckland, right,
doesn't get that cold. Before I get text from someone
in the Deep South winging about Jaffas and all the.

Speaker 2 (04:05):
Rest of it.

Speaker 5 (04:05):
It was just while I was stretched down on the
couch last night, kind of recovering from another bout of
the cold, I thought, gee, I could do more?

Speaker 2 (04:13):
Will I do more?

Speaker 6 (04:14):
Not?

Speaker 5 (04:15):
Sure?

Speaker 2 (04:15):
We'll see what can you do?

Speaker 7 (04:17):
Oh?

Speaker 5 (04:17):
Eight hundred eighty ten eighty that's what you can do?
You can give me a call, you can also send
me a text if you would like. That's nine two
nine two is said BZB from your mobile phone, and
if you would like to send me an email, it's
Pete atnewstalksb dot co dot nz. This today on the show,
no particular guests organized, no specific experts that we're going

(04:38):
to try and chat to. Again, Like last Sunday, we
have a slightly truncated show in the sense that we're
out of here by eight forty six. We can hand
over to the sports team and they can get you
fantastic coverage of the match between Lost Boomers and the
All Blacks that will kick off just after nine o'clock,
so by quarter to nine we're out of here. We'll

(05:00):
bring Rid in a little earlier, so he will be
with us from just after eight twenty. Talk all things
gardening with Rude from eight twenty. But right now it
is your opportunity to talk all things building and construction.
Just a heads up because I'm doing a bit of planning.
So a couple of really big stories that are out
there in terms of politics and in terms of construction

(05:24):
and housing. Possibly the most significant announcement of the last
couple of weeks and arguably because these things get trumpeted
as headlines of you know, the most significant to the
change to the building sector, a residential building sector in
the last twenty years is what has been long talked
about is a change from what we call joint in

(05:46):
several liability to potentially most likely proportional liability when it
comes to what happens when it goes wrong. And we'll
talk about it in much more detail over the next
couple of weeks, but it's been a significant issue, i think,
within the sector for a long time, and it's been

(06:06):
a significant issue for counsels who ultimately when something goes
wrong and if they've issued a code compliance certificate to
a property, they have responsibility for much of the defects
significant defects for that property for the next ten years.
And so if you are inevitably going to be responsible

(06:29):
for somebody else's work, which is the nature of joint
and several liability, then you're going to be risk averse. However,
if we shift to proportional liability, councils perhaps will maybe
take a different approach. Notice there's lots of maybe's, ifs,
and butts and so on, So to take a bit
of a deep dive into this not next Sunday on

(06:50):
the program Sunday following Mike Thornton, who's been a lawyer
who's been on this program a number of times because
this is his particular field of expertise in terms of
litigation around building defects, will come through and we'll have
a bit of a chat around what that might look
like in reality the following Sunday. At this stage, hopefully
we're actually getting the Minister Chris Penk. He'll come back

(07:14):
to the studio like you did earlier in the year,
and given that this is basically within his portfolio he's
been driving this change, a good opportunity for him to
explain what it is that he's looking to achieve and
how it might work out. Again, lots of discussion among
the sector. Is this going to be a good thing?
Is it slightly short sighted? And ultimately the greatest concern

(07:36):
should be where does that leave the consumer? You and
I who might buy a house and then find that
there are defects and then find that we can't get
someone to fix it. So how do you end up
protecting the consumer with all of these changes? So that's
coming up, that's over the next couple of weeks, so
really looking forward to that a bit of a deep
dive into some of these fairly significant changes to how

(07:59):
we manage both risk and defects and where that risk sits.

Speaker 2 (08:06):
Wait, hundred in the is.

Speaker 5 (08:10):
Oh eight hundred eighty ten eighty is that number to call?
Give us a call? I shouldn't have opened the door
to that text, but of course I did. Someone's complaining
that I'm winging about it being cold. It's just add
a hot chair a cold chair, and he's off to work.
Good on you if it works for you, that's fantastic.
Oh eight hundred eighty ten eighty The number to call
will take a break. We'll take your call straight after

(08:30):
the break. Lines are free right now. So if you've
got a question and we don't have as much time
today as we normally do on a Sunday, now it's
a great time to call.

Speaker 2 (08:37):
Oh eight hundred eighty ten eighty.

Speaker 1 (08:40):
Doing of the house storting the garden asked Pete for
a hand the resident builder with Peter Wolfcap call Oh
eight eight eighty us dogs, that'd be right.

Speaker 2 (08:49):
Oh, lines are open.

Speaker 5 (08:50):
Oh eight hundred eighty ten eighty is that number to call?
First text in the morning, Morning, Pete, I'm repainting the
house this year. Need to replace some soakers. Any tips
on how to remove them without denting or damaging the
weatherboards thanks from Nick. Typically it's like there shouldn't be
any fixings that are concealed, let's say, by the weather

(09:12):
board above. So if you've got a corner soca on
a typical timber weather board house that's had a sort
of mighty junction on a corner and then the soka
goes over it. Once you pull out the nails, and
in some cases you may not be able to get
the nail out. But if you basically use a chisel
on old chisel or something like that and just snap
the head off, the flathead head off the old nail

(09:35):
that's in there. Once you've just pried the weather board
above it open just a little bit, you should be
able to just pull that soka down and slide it out.
So it's often just a case of sort of getting
getting the nails out, opening the pulling the soka away
a little bit, and then being able to grab it
with a pair of plies or something like that and

(09:56):
just yank it down. Inevitably it will you know, it'll
ruin the paint line between the two weatherboards or lines
of weatherboards, but you can generally get them out and
then replace it. You can get stainless steel ones now,
which if you're in a coastal area or in your case,
if you've had quite a lot of rust, might be

(10:16):
not a bad investment, So stainless steel corner soakers as
well as stainless steel nails to fit them in, and
then the appropriate edch prime over the top of it
and then painted from there. If they're not great but
still kind of okay, like not completely rusted through, then
just some rust kill and primer is possibly enough. Just

(10:39):
you know, go like use a flat disc or something
like that on a grinder just to really knock back
that rust, and you might even be able to save
a couple. But generally, once they've got the nails out
and you just drive a chisel or a flat prybar
up under the board above just enough to give you
a bit of gap yank them out the way you go.

(11:03):
Just talking about you know, I suppose this is the
time of year that that our focus is on how
does our house perform in terms of you know, does
it keep you warm and so on. I mean, look,
I know buy and large. I can heat the house
and it's warm and comfortable. It's just sitting in the
front room last night, I could feel the house fighting
against the weather outside. Basically it's cold outside. That cold

(11:26):
wants to come in, and I want to try and
keep it out. And my house does an okay job
of that, but not a great job, not by comparison
to what you can do today. So someone Simon's text through, Hey, Pete,
I spent fifteen grand in April. I increased the ceiling
and floor insulation. I put in some new lighting, I
put an arrangement, I put in a bathroom fan. I've
done some ventilation along with a heat pump. Hoyas is

(11:49):
now warm and dry.

Speaker 2 (11:50):
It's so good.

Speaker 5 (11:52):
Thanks Simon for that. I mean, good on you for
doing that too. What I'm intrigued about, and this is
the other thing that I'm going to reach out and
get some banking basically comment or advice from is people
takeing up options for loans from their banks around making

(12:12):
basically energy efficient changes to their house and being able
to get incredibly low rates on their mortgage for that work.
So in this case, here, and I would be curious, Simon,
if you wouldn't mind text me again, did you go
to your bank, for example, and say, this is what
I intend to do, and I'd like to borrow that

(12:34):
fifteen thousand dollars and you might have been able to
do that at let's say, a one percent loan for
three years. I know a couple of banks are starting
to do this, and I've noticed that a number of
people are starting to take up exactly that option. In fact,
we were talking with friends the other day who actually,

(12:55):
this is interesting. They've bought a new house, a new build,
but it doesn't have solar. Now I'm not saying you
have to put solar in, but it's not a bad idea.
It's in a new house. It's a house that requires
a fair amount of heating. They're in a cold and
a genuinely cold part of the country, as opposed to
me as a little soft jaffer up here complaining about

(13:16):
it being I don't know, four or five degrees outside,
and so they're thinking about putting solderin. And we were
chatting and I said, you know, have you considered these
low interest loans because you could do that on a
house like that or any house, to be fair, and
it's exactly what they were doing. A couple of weeks
ago on the program, someone rang and said, yeah, look,
I'm doing this whole sort of energy efficient retrofit on

(13:37):
the house, and I've been able to go to my bank,
so this is what I intend to do and get
the loan. So Simon, i'd be interested to know whether
or not you sort of looped all of that together
and went to your bank and said, Okay, here's my upgrade.
It's going to cost me fifteen grand. Can I borrow
that please at one percent interest generally for about three years.

Speaker 2 (13:57):
That's great.

Speaker 5 (13:59):
So anyway, we're going to get some professional advice on that.
I've got someone that I spoke to at a conference
the other day who's involved in this, so we'll get
them on the show as well.

Speaker 2 (14:07):
That's great. Actually, just on that too.

Speaker 5 (14:10):
One of my little jobs this week was putting in
a bathroom fan. Who exciting. Yes, it was because it
was a constant flow humidity sensor bathroom fan, and so
it was in a bathroom of a rental property and
the issue had always been that this particular bathroom paint

(14:31):
was peeling off the ceiling. There was a little bit
of mold growth in there, and it was just a
persistent issue. So painters came through. We stripped the ceiling,
patched it, painted it with some really good quality paint,
cleaned up a whole lot of other things, and then
I got the Sparky's in the other day to take
out the existing fan which was okay but not great,

(14:52):
and replace it with a simics constant flow fan. So
this is a little just went straight back in the
same hole and it had a very short run of ducting,
which is ideal, so just up through the ceiling and
into this AffA. But the fan has a humidity sensor
on it, so you can set that for whatever rating

(15:13):
you wanted. We went for sixty percent humidity, and then
actually got the electrician to change the mech on the
switch at the door so that it had a little
cover on it so you can turn it on, but
then you're discouraged from turning it off because you'd have
to lift the cover and turn it off, so it
kind of just says it's on, leave it on, and
then so we fit it in it and then to

(15:35):
test it, we turned the shower on, so the fan
goes in and it runs at a very low rate
all of the time, and then sure enough we turned
the shower on nice and hot. Lots of shower came out,
lots of steam came out, lots.

Speaker 2 (15:48):
Of warmth came out, and the fan ramped up.

Speaker 5 (15:52):
To cope with humidity and stayed at a higher level
until the humidity in that room dropped down to less than.

Speaker 2 (16:00):
Sixty percent, which I thought was actually genius.

Speaker 5 (16:04):
Anyway, So we whacked one of those little interesting go
found out the show it was leaking to when I
did that too, so that's another job to do. This
is the nature of things. But the fan was very,
very cool, so that.

Speaker 2 (16:20):
That's going to be my go to.

Speaker 5 (16:21):
This was a little Simmis siemx fan that I installed
in that particular rental property with Devenport Electrical.

Speaker 2 (16:29):
Just the other day.

Speaker 5 (16:30):
Right, yoh, it's time for you to call Oh eight
one hundred eighty ten eighty is that?

Speaker 7 (16:33):
Ah?

Speaker 2 (16:34):
Here we go.

Speaker 5 (16:34):
The text are coming in about the I's going to
say free money. It's not free money, but I think
it's really interesting that people are really starting to pick
up on this high.

Speaker 8 (16:44):
Yeah.

Speaker 5 (16:44):
We borrowed eighty K for new windows like double glazing
and a new heat pump at one percent interest for
three years. It's easy. At Hey, look, if someone wants
to give me a call about this, I'd be really
interested to talk about it. I just think that, and
I've heard of people doing it, even for new builds.
So if you go, I'm going to build a house,

(17:05):
but these are the energy efficient features of the house,
you can borrow a portion of your mortgage at a
lower rate. So eighty grand for new windows with double
glazing and a new heat pump at one percent for
three years. Interesting. Interesting, Oh, eight hundred eighty the number

(17:27):
to call. That's that's really cool. Other quick texts Pete,
why do we feel extreme cold coming up from the
concrete block base of a new build? And then they
mentioned a development. This is mainly on the south facing
bedroom and not on the north facing garage directly opposite.
It is ridiculously cold. We aren't sure what can be

(17:49):
done as the heat pump warms the air, but the
chill comes up from the ground. Gerard, you've you've made
a really interesting observation basically around building science. And if
you look at the new building code and the insulation requirements,
most likely you would need slab edge insulation for a

(18:10):
home to get to the right energy standard for the
new H one regulations. So remarkable and I've seen some
sort of research on this. Could be about fifteen percent
of heat loss is coming out of that junction between
your wall and your concrete slab. So that would probably

(18:32):
tally with what your experience is there that in this
particular bedroom, what you're getting because if you imagine you've
got concrete which is not it has some insulation performance,
but not a great deal, right, and then you've got
the cold air on the outside of that, you've got
that junction, you've got a timber bottom plate. Then your

(18:52):
insulation starts above there, but you've got quite a big
segment there that's exposed to the outside. You've identified it
as being on the south side of the house. You
will get a lot of cold there coming through and
migrating into the house through that particular junction. There is
an option for a retro fit in that system. You'd

(19:13):
want to have a look at razine construction.

Speaker 7 (19:15):
They do.

Speaker 5 (19:17):
Basically, it's a an EPs it's an expanded polystyrene that
can go on the outside and it's got a tape
at edge that it doesn't impact with your weather tightness
and your drainage for your cavity system and so on,
and that would help on the outside of that. So
there are solutions to what you're doing. Oh, eight hundred
eighty ten eighty is that number to call. Sorry, there

(19:39):
are solutions for that particular issue in that house as well.
But if you were building new and you did slab
edge insulation, then that would mitigate, will reduce significantly the
amount of heat loss through the corner of the slab, which,
like I say, can be as much as fifteen percent.

Speaker 2 (19:57):
Right it is six twenty nine. We're onto it.

Speaker 5 (19:59):
Eight hundred eighty ten eighty the number to call Andy,
Good morning.

Speaker 9 (20:03):
Good morning, Peak.

Speaker 10 (20:04):
How are you.

Speaker 2 (20:04):
I'm doing all right, Thank you.

Speaker 9 (20:06):
Doing all right even with the weather in Auckland.

Speaker 5 (20:08):
Well, look it just last night I sat there on
the couch and I thought, you know, for all of
the I'm in an old house, right, and I've tried.

Speaker 9 (20:17):
To I'm not complaining because I'm in Auckland too.

Speaker 5 (20:20):
And last night it was cold, right, and I was
blah blah blah. Anyway, I'm not going to win anymore.
I'm not I'm just saying it's an observation. There you go, right,
what's on your mind?

Speaker 9 (20:30):
Well, the first thing is you just had the conversation
about borrowing money for you upgrades. So I had some
double glades windows put in, yes, and I didn't even
think about that at the time. And then I contacted
my bank after and said, hey, I had this done.

(20:51):
Can I borrow the money retrospectively? And they said, no problem,
just showed me the show me the invoices and.

Speaker 7 (21:02):
Yeah.

Speaker 9 (21:02):
So they came up and again one pretent for a
couple of years. So it was well worth trying, even
after doing the work.

Speaker 2 (21:11):
How interesting.

Speaker 5 (21:12):
And I mean, look, you know this, it's like with
all financial advice. This is not general advice blah blah
blah blah blah. But look, I just think, you know, one,
we're often down on the bank. So good on the
banks for making this offering. And I know why they're
doing it. There's a whole lot of politics behind it
and all the rest of it. The reality is they
are doing it right. And I think for most of us,

(21:36):
the barrier to making significant upgrades is, hey, look I've
already got a mortgage. You know, it's already costing me
an arm and a leg. I just can't afford to
do it right. But I think in this instance here
where you know, I know friends who are thinking about, hey, look,
I've got gas at the moment, which is okay, but
I'd like to get off it sort of thing could

(21:57):
I do sort of you know, some solar maybe a
battery and a heat pump, hot water system, and then
I'm sort of off the game, you know, and maybe
that'll pay for the cost of an induction hob as well.
And then that little package takes care of.

Speaker 2 (22:14):
All of my needs.

Speaker 5 (22:15):
And maybe that's a I don't know, thirty thousand dollar exercise,
but I'll do that at one percent and the way
we go. So, hey, that's really exciting.

Speaker 9 (22:25):
Yes, But the reason I'm ringing's something different is We're
in a concrete a concrete block house, and I've got
a leak in a I've got a crack in one
of the mortar joints. It's underground and under a driveway.

(22:51):
So I'm sort of loathed to go, let's dig the
driveway up. I know that would be the best way
to do it fixed from the outside, but I'm thinking
the only the real practical way is probably to do
it from the inside because it's only seeping. It's not
a bad leak. It's more that you get a little

(23:14):
few drips and the calcifications coming through down the wall
because the wall is exposed, it's painted, it's been past
it and painted concrete. And I've looked at the various
solutions and most of them seem to do tanking type solutions,
which is some sort of film and I'm thinking that

(23:36):
that may not fix it as well as it should.
I'm already thinking if someone would about inject something into it,
and I'm.

Speaker 7 (23:46):
Not going to.

Speaker 9 (23:47):
I'm thinking this is also a professional facts, not me
trying to do a fix here.

Speaker 7 (23:52):
But I can't.

Speaker 9 (23:54):
From my research, I haven't found anyone that sort of
specializes in all sorts of fixes.

Speaker 7 (23:58):
They just do.

Speaker 9 (24:01):
Just tanking. And I'm wondering if you knew of somebody
with your knowledge in Auckland, of someone that would be
able to come in.

Speaker 2 (24:10):
And say, oh, here's here's a solution, here's.

Speaker 7 (24:13):
The solution you need.

Speaker 9 (24:15):
Thinking won't work injection world.

Speaker 5 (24:17):
Yes, I can do that, yep, yeah, I do have
it happens. Yeah, I'll give you a number off here
rather than on are But.

Speaker 2 (24:27):
Because because just a quick question on it.

Speaker 5 (24:30):
So the space where you're seeing the leaks, that's obviously
a habitable space. It's being painted and that sort of thing,
because you know, one of the most common fixes for
this is like a crystalline solution, which is your applied
on the inside to bear mortar, and that works quite well,
but you can't paint it and those sorts of things,
So that's not going to.

Speaker 7 (24:50):
Work for you.

Speaker 9 (24:52):
Having listened to your show previously that you didn't mention,
did research that, Yeah.

Speaker 5 (24:57):
Okay, because generally that's a very effective solution, but it's
it's it has some limitations. So yeah, I was talking
to a building surveyor that I know, so you know,
proper registered building surveyor who's involved with the company that
do an injected system, which is what you're talking about,
where essentially they do injections at maybe one hundred million

(25:19):
centers across the entire wall and then inject an epoxy
into there that seals all of those areas. So stay
on the line and I'll give you a number.

Speaker 7 (25:32):
Before you go.

Speaker 9 (25:34):
Because yeah, because the crack is so fine, Yes it
needs some very liquid.

Speaker 7 (25:40):
Yes, you know it gets through.

Speaker 5 (25:43):
Yeah, it's when I say a POxy, it's like I
mixed up a two pot of POxy would glue the
other day to repair something. It's not like that.

Speaker 2 (25:52):
It is specifically designed to design this filter.

Speaker 5 (25:56):
Through those microscopic cracks and seal those cracks on the inside, right,
seal all of those all of the pores basically in
the in the masonry. So yeah, happy to pass on
that number to you. Stay on the line. Thanks very much, Pete,
my pleasure. Nice to talk with you. Let's take a
short break and then we'll come back. Now we've suddenly

(26:17):
got a full boarder court, which is awesome. Oh, eight
hundred eighty ten eighty the number of coll.

Speaker 1 (26:21):
Whether you're painting the ceiling, fixing the fens, or wondering
how to fix that hole in the wall.

Speaker 2 (26:25):
Give Peter wolf Cap a call on eighty the resident
filder on Youth Dogs' B.

Speaker 5 (26:32):
Here new b coming up twenty one minutes away from seven.

Speaker 2 (26:36):
Really good morning, Renee, Hello, morning morning.

Speaker 5 (26:39):
Are you doing morning, Pete?

Speaker 7 (26:40):
How are you good? Good? Good good? Yeah.

Speaker 11 (26:45):
I'm bringing them regards to your comments that you made
earlier on in regards to doing the bathroom, Yes, and
number offend and that now I've got the same issue
at my place. Our is about so it was maybe
a late sixties built. We had the bathroom renovator maybe
I think maybe four years ago we had a shower

(27:05):
upgraded and they came in and repainted the roof and
the walls and all that sort of thing. But unfortunately
that company is not around anymore. Yeah, and the fans
stopped working maybe a couple of months ago. And yeah,
and around the fan is black mold and it's starting
to peel.

Speaker 7 (27:25):
Yep.

Speaker 11 (27:25):
And in the corners where where the wall meets the
roof in certain areas you can notice some black mold.
And where the showers we used to have a curtain,
but they put in a new lining and a glass door,
and there's a gap in between the glass door at
the top that can't that the steam and that can
come out into the bathroom and above and above the
top of the shower there where it's the white lining

(27:46):
or whatever that's got black mold and everything we'll try
cleaning and everything that's not it's hard to get rid of.
So what I'm asking is is it a job that
you can do yourself?

Speaker 7 (27:56):
Is it a big job?

Speaker 11 (27:57):
Or what am I looking at sort of money wise,
if you if you're off the top of your head's
come in and do that.

Speaker 7 (28:04):
And with the fan. I noticed I heard you say about.

Speaker 11 (28:07):
Your fan, something about the constant. Yes, yeah, yeah, because
our shower gets like I've got. We're a family of
five yep, for women and myself, so they like to
have their showers and at the moment, all we can
do is open that window after the shower to let
the airflow and to stop the moisture, to get the
moisture in that out. But I want to put an

(28:28):
I was thinking two fans, one above the shower and
one in the bathroom somewhere, just to just to help
get rid of that moisture that's building up in there.

Speaker 7 (28:37):
Yep.

Speaker 5 (28:39):
So yeah, okay, So the most challenging part of what
you're describing is that it takes time to do this well.
And you're a family of five, and if that's your
sole bathroom, then that's a real challenge.

Speaker 7 (28:52):
Right.

Speaker 5 (28:52):
So I had a similar thing in another property a
little while ago, but it was it was in between tenancies,
so I was able to let the space dry out.
I went in myself and I used a razine wall
prep right, which is like a mold killer as well,
which is quite aggressive because when I got it, you know,

(29:13):
I'm a bit messy, and so when it dropped onto
my shirt, it took all the color out of my shirt.
It's that sort of active product, right, And so I
went through and I wiped all the ceilings down and
then I rinsed all of that off. Then I let
them dry really thoroughly. Then I sand it hard. Then
I did an oil based pigmented sealer and I let
that dry for twenty four hours, and then I coated

(29:34):
it with what they call a rasine velvet paint, which
is like a water born enamel, so it's really hard wearing.
And then I upgraded the fan in there. Do you
have any heating in the bathroom as well, like.

Speaker 7 (29:50):
Tae heat, Well, it's not a fan here.

Speaker 11 (29:53):
It's like your old school element heater.

Speaker 5 (29:56):
Yep, Okay, you pull the cord and it y comes on.
It's not one of those serene heaters. Just we won't
mention that later on. But you know, the hard thing
is like to to really do a good job in
terms of drying that room out, treating the mold, letting
that dry, then painting it and then letting the paint

(30:18):
cure properly. Is you know, it's a minimum of five
to seven days, right.

Speaker 7 (30:24):
So I was just going to say, it looks like
it's a week week.

Speaker 2 (30:27):
Yeah, that's and.

Speaker 5 (30:28):
That's really realistically for you guys, that's impossible, right unless
you're away. Yeah, So that that's that's probably your biggest challenge,
and not following those steps won't get you the same result.
That's there's no other way of like really properly repairing
that situation without having that amount of time, in my opinion,

(30:50):
So the issue.

Speaker 11 (30:51):
There probably Yeah, I work seven days a week, so yeah,
sounds like it will have to be someone will have
to come in and do it.

Speaker 5 (30:58):
So and it kind of sounds like, yep, yep.

Speaker 11 (31:03):
Yeah, if I advertise that job, how do I find
out that the person that's taking that job on is
qualified to be able to do the work. Because I
have a feeling that the people that we got in
to do the work originally when we had the bathroom
renovated about four or five years ago, I don't think
they probably did enough work or anything.

Speaker 7 (31:20):
Because that's why I'm feeling the roof.

Speaker 12 (31:22):
And all that.

Speaker 5 (31:24):
In ninety nine percent of the time where you've got
problems with paint work later on, it's always to do
with the preparation, right, So that's your biggest challenge. So
really it's a case of it's not so much a qualification,
it's an awareness, right, So you've got to work with
a tradesperson who understands what the problem is and goes, hey, look, realistically, mate,

(31:45):
I'd love to tell you that my boys will be
in here tomorrow and will be finished, you know, in
two days time. Then you know that they don't know
what they're talking about because you just can't do this
work in that amount of time. And then with regard
to the fan, I don't know that necessarily having two
fans is I can see the logic of saying that
will be an advantage, but I think that one fan

(32:06):
will do it. The other thing with extraction in a
bathroom is that sometimes what we don't realize is that
if you're extracting air out, you've also got to allow
ear to come in. So, for example, if the gap
underneath the door is too small, it's not allowing sufficient
ear to come into the bathroom for that amount of
air to be extracted out. So again, if I would

(32:27):
say the gap underneath your door should be a minimum
of let's say ten to even fifteen millimeters, which I
know seems like a lot, but it will allow that
ear to come out. And then the advantage that I've
seen with this constant flow fan is that again typically
what we do is we jump in the shower, we
turn the fan on, we finish brushing our teeth, we're

(32:49):
out the door, we close the door, turn the fan off, right,
and that moisture stays in there for it forever, right,
Whereas if the fan is running all of the time,
so it'll run at a higher rate when there's lots
of moisture. As it dries out, it'll run to a
lower rate, but it'll continue. So there's constant airflow through
that room that will make a big difference as well.

(33:09):
And a little bit of heating in there from your
heat to tawel rail that will help just keep that
moisture at bay as well.

Speaker 11 (33:18):
Yeah, because I've noticed in the winter time as well,
when if the bathroom doors left shut with the cold outside,
you make it up in the morning because on the
first one up there is there's water build up.

Speaker 7 (33:28):
On the window sill.

Speaker 5 (33:28):
Ye little bit connensation from the in station.

Speaker 7 (33:31):
Yeah, and it's quite quite a good like a flow
of water on. I noticed.

Speaker 11 (33:36):
I've said to keep the bathroom door open at night
because we have the heat pump on at night, obviously,
keep and that lets the Yeah, that lets the flow
go through.

Speaker 7 (33:44):
And it's fine.

Speaker 11 (33:45):
Do you know off the top of your head what
i'd roughly be looking at to get the work done.
Off the top of your head with.

Speaker 5 (33:50):
Mentioned, I mean it's it's going to be two grand
or something like that. I mean, you know, it's it's like,
it's not difficult work, it's just it takes time, right,
and and some things, you know, we love to think
that everything can be done really quickly, but some things can't.
So it's getting a contractor who's prepared to come into

(34:12):
raally thorough job with the cleaning, then come back when
it's thoroughly dry and send it back and use like
a pigmented seala which takes a little while to dry,
and then come back and use the right type of paint.
So it's not expensive, it's just.

Speaker 7 (34:26):
Time, that's right. Yeah, expect to be a bit more
of the two, to be honest.

Speaker 2 (34:33):
Yeah, ask around.

Speaker 5 (34:35):
But I think when you're talking with a contractor about
doing it, you've got to listen to them going oh, hey,
look this is what I'm going to do. And I
think as soon as you find someone who goes, yeah,
I understand what the problem is and this is how
we're going to solve it, that's great, but ask those
questions beforehand. Hey, awesome to talk with you, and good
on you for doing the work that you do. Really

(34:57):
appreciate it and good luck with that. Andy, good morning
to you.

Speaker 10 (35:02):
Good morning, morning morning, a long time listener, first time caller.

Speaker 2 (35:06):
Lovely to have you with us.

Speaker 10 (35:08):
Yeah, that's great. Hey, look we're doing We've got the
we're doing a new build beach house yep. And we're
going for laminate floor yep. And our builder boys are saying, oh,
we can put that same laminatee right through even in
the bathrooms. Now we're looking at here. We've got a
it's a Godfreyhearst armor and that's the one we like.

(35:32):
How will this cope with being in laundries and bathrooms?

Speaker 5 (35:37):
I mean, the great couple of options. One is like
I know of systems where it's like it's designed for
basically wet areas as well and so I've seen engineered floors,
laminate floors, clip together floors that they specifically designed for that,

(35:58):
so they'll deal with it. Others won't. So the best
thing to do, I think is probably if this is
a product that you like, ring the manufacturer directly and go, hey,
can I talk to you about what's going to happen
when it goes into the bathroom and are there some
specific things that I need to do? So, for example,
will it be installed over a concrete floor?

Speaker 7 (36:20):
No?

Speaker 10 (36:20):
No, No, It's over a.

Speaker 5 (36:22):
Timber floor elevated yep. And then you know, ask them
whether or not there's things like do I need to
seal around the edges or do I need to do
a waterproof membrane underneath over the top of my substrate?
So does the timber floor need to be waterproof before
I install the laminate flooring over the top those things,
and there will be specific information in the specifications for that,

(36:47):
and yeah, so yes and not. I was going to
say in theory, it's not actually in theory. I mean,
I've seen displays where this laminate flooring, where do I
see it? Our quick Step, which is another brand right
that does laminate floora.

Speaker 10 (37:01):
I've got a sample of quick step here, but we're
not so happy with the color of it here.

Speaker 5 (37:06):
That's fine. All I'm saying is I've been to the
showroom and all the rest of it, and I've seen
examples where literally it's kept in water, right, So there
are systems that we can do that with. So yeah,
go back to the manufacturer, ask them if it works
in that space. If it does, get the specifications and
make sure it's installed as per the specification.

Speaker 10 (37:26):
Okay, all right, that's fine with a new but also
with a new build that's going to be shut up
quite a lot of the time. Yes, we're wondering about condensation. Yes,
good point, it's fully you know, it's a new build
of double.

Speaker 5 (37:44):
In your planning for the building, have a look at
some sort of constant extraction, right, and there's there's like
ventilation systems have Well maybe we've caught up to the
rest of the world, but there's there's now a tremendous
amount of work being done around how we should ventil
out our houses, given that we're moving more and more

(38:05):
towards bils that are much more air tight than they've
ever been. And air tightness is a good thing, but
with air tightness. It's got to go hand in hand
with ventilation. So there will be some relatively simple systems
that you could install while you're building the house, so
not as an add on later on, that will allow
you to manage moisture inside the building. So spend a

(38:28):
bit of time.

Speaker 7 (38:28):
Have a look.

Speaker 5 (38:29):
I tell you what, have a look at some of
the brand's research right around this. They've got some really
good articles online that will introduce you a brand. So
the Building Research Authority of New Zealand just go to
brand search ventilation and you'll see. You know, it's like
introduction to some of this building science. It's worth spending

(38:52):
the time reading on that, getting yourself up to spec
and then going okay, that's a system that I'm going
to install. And I look, if it was me and
I was building you, I'd definitely put in a mechanical
ventilation system. And for a house that's going to be
locked up, you know, I think it's worth spending the
five to ten grand that it's going to cost you

(39:13):
to do a decent system. I think that there's tremendous
value in that. I got to run for a break.
Good luck with the build, and lovely of you to
call and let us know how you get on. Oh,
eight hundred and eighty ten eighty is that number to call?
Six fifty one.

Speaker 2 (39:28):
Squeaky door or it squeaky floor.

Speaker 1 (39:31):
Get the right advice from Peta Wolfcare, the resident builder
on News Talks B.

Speaker 5 (39:37):
You and News Talk c B. This is I'll take
a bit of a deep dive into this later on bathroom.
Never use a fan until you've finish the shower heater
first till you've finished the shower, then fan for on
a seven minute time. Never bring cold air to hot water.
Jim and might could you'd give me a call on that.
There's obviously a bit of building science in there that
you want to talk about, right, Oh Stuart, good morning

(39:59):
to you, sir, Good morning, Good morning peat.

Speaker 6 (40:04):
My question is another one around CONDENSA so little bit
different pictures at carpet now all of them seem to
have color see or rooms with nothing underneath. And when
I've done carpets in the past, I've always put building
paper underneath the roofs AM. I like to have a AM,

(40:25):
I like to have a problem conversation with these new ones.
Without anything like.

Speaker 5 (40:30):
That, you will get condensation and you really can't prevent
it if you've got an iron roof that that's exposed,
let's say, on the underside and the top side right,
And that's the nature of a carpet because it's not
inclosed space. And interestingly enough, typically the approach is you're
going to get it, so let it just drip right,

(40:53):
in which case most of the time, when I've seen
building paper that's been installed under car ports, it tends
to deteriorate and fall apart. So the standard practices, you
accept the limitations. You just put up the iron and
let the condensation do what the condensation is going to do.
So and that's that's typical practice. I tell you what, Stuart,

(41:14):
we might have to just pick this up again after
the news because I've run right into the news break
at seven. Remember, but we have live coverage here at
news Talks. Heb of the All Blacks versus Argentina at
just after nine o'clock. So we're out of here at
eight forty five today, So in the next hour, get
in quick, oh eight hundred and eighty ten eighty. If
you'd like to give us a call right now, we'll
get things set up. Take care.

Speaker 1 (41:36):
Helping you get those DIY projects done right. The resident
fielder with Peter Wolfcat call oh eight eight youth talks right.

Speaker 5 (41:45):
Yeah, we're going to have a big debate with Jim
soon about what the proper way of running your fan is.
But before we do that, sorry, we burst into the
news with Stuart. So Hey, Stuart, just just a confirmation
on that if you're going to do so standard practice
car port, it's exposed underneath. It's obviously exposed on the top.
Typically we don't put a roofing underlay there because it

(42:08):
tends to be exposed and it deteriorates. Now, possibly some
of the new roofing underlays might be more durable, but
you know, in the old days with the black paper, right,
which was the standing roofing underlay, that just deteriorates over
time and then once it gets a rip in it
or it splits, it's kind of pointless.

Speaker 7 (42:32):
There's not a.

Speaker 6 (42:34):
Insulation you might be able to pop on.

Speaker 5 (42:40):
I don't know that that well, yeah, you can do
spray phones and that sort of thing, but you know,
getting it to stick and getting it to well, getting
it to sticks not a problem, but getting a decent
finish on it might be a bit odd. There are
insulated panels that you could use that sort of thing.
The other one other option is but you would need
to go specifically to a New Zealand steel product or

(43:03):
a Blue Scope product, which is color steel with a
membrane attached to the underside called dry core, and use
that for your roofing, so that eliminates the need for
a roofing underlay. And it has proven to be very

(43:26):
very effective. But if you're buying a kitset, chances are
it will come with the roofing already attached to it,
you know, like as part of the kit. But if
you wanted to just go specifically for one type of iron,
then you could go for that dry core. I think
it's called.

Speaker 7 (43:42):
Have a look.

Speaker 5 (43:44):
Nice to chat with you, take care bother them. I'll
just check the terminology on that and have a look.
So we were talking about fans, and we talk about
them a lot because ventilation is really really important, and
a text came through that said, bathroom, never use the
fan until you've finished with the shower. Put the heater
on first until you've finished the shower, then the fan
on with a seven minute timer. Never bring cold air

(44:07):
to hot water silly, it says Jim, And Jim's on
the line, good morning, good morning, right, run me through
the physics of this, right.

Speaker 8 (44:17):
Dealing with a lot of renters and fixing things.

Speaker 7 (44:20):
Yep.

Speaker 8 (44:21):
I ended up saying you shouldn't put a bloody fan
in the in the bathroom without having some form of heat,
and landlords, the landlords becoming it's a problem sometimes don't
want to spend anything, sure, And he says, I know,
that's that's the way we do it. And I said,
it's an insult. If it's freezing cold and you turn

(44:44):
the light on, the fan goes on, it's freezing, it's
more colder you're coming in. It's just more moisture. If
you want to fix it, just all you don't do
is just turn the fan off. And you can't put
most old wirings. So you put a pool stop switch
up on the ceiling, but connect to the fan so
you can put it on and off, and put a

(45:05):
fan heater at the door, open the door up for
the fan on heater at the before you have your share,
and just leave it on and warm the place up,
and don't turn the fan on until you finish your share.
There won't be any moisture.

Speaker 5 (45:23):
Okay, look cold air and all.

Speaker 8 (45:25):
The time, all the time, pausing more condensation.

Speaker 5 (45:30):
Presuming that the ceiling when when you say cold, like,
what would the interior temperature need to be in order
for that theory to work.

Speaker 8 (45:42):
I've never worried about that any anytimes. Anything good enough.
It's it's just it condensates. If you pull coldier. And
if you've got a fanger and you're pulling coldier and
you're running a share which is hot, you're condensating. You've
got moisture on your roof, on your ceiling, so you've
got it dripping after a while, especially if there's more

(46:05):
than one having a share. So the easiest way is
just heat it. Okay, put eater outside outside the door
and bring it in if.

Speaker 7 (46:15):
You need to.

Speaker 8 (46:15):
But you've got to be watching with prepair with water.
But you need the warmth. There's no moisture, there's no
condensation that all. If you run a heater all the time,
just isn't any.

Speaker 5 (46:30):
I'm fascinated by this, but I also realize that for
some people that this is this is like eye wateringly boring.
It isn't. I think it's fascinating what I'm going to
do is I've written some notes. I'm going to take
your theory and I'm going to go to an expert
and I'm going to run it past them and I'm
going to see if there is some validity to it.

(46:52):
I kind of get where you're coming from, but I'm
gonna I'm going to get it independently veripified by an
expert and then I'm going to tell you all about
it next week. Really appreciate you calling, Jim. I really do.

Speaker 2 (47:05):
It's an interesting theory.

Speaker 5 (47:06):
I think there's some science to it, but I'm going
to run it past, like literally, an expert who's got
a degree in this particular area. So thanks again, Jim,
I really appreciate it. Oh und eighty is the number
to call.

Speaker 2 (47:19):
Steve.

Speaker 5 (47:20):
Very good morning, Steet.

Speaker 7 (47:25):
He might have been thinking about turning your whole bar
for him into a giant shower dome in a way,
but I can't see the practicalities of it, because if
you've got a good fan over the top of your shower,
that's going to get rid of that that that that
you know, condensation, well it's not going to have a

(47:46):
chance of that. You're not going to get the build
up on the selling and with the heat that people
run their showers of hot water, Yep, I think you
have to heat up that room a lot for the
gates that you know. That conversation. Yeah, I'm not sure
about that one.

Speaker 5 (48:04):
And that's why I asked, you know, what's the exterior temperature?
And by that, I mean what's let's say, you know,
most of us have got the bathroom off the hallway.
Let's say, right, so what's the temperature in the hallway
and what does it need to be in order for
this theory to work? And again, you know, obviously we
all think about our own places, and so in my head,

(48:26):
I've got the hallway, I've got our bathroom next to it.
I know, because I've got a thermostat in the hallway,
what the hallway temperature is?

Speaker 7 (48:37):
And what about heat of the hot water?

Speaker 5 (48:41):
Well, look, I love a hot shower and I like
a long hot shower. So mine's basically going to be
it's going to come out at you know, forty eight
to fifty degrees. I'm thinking maybe maybe a little bit
less than that.

Speaker 7 (48:55):
But yeah, I'm not not completely sure on that one.

Speaker 5 (48:59):
Yeah, I've got someone in mine I'm going to I'm
going to wring them on Monday. I'm going to go
right tell me if this theory works anyway, How can
I help with your question?

Speaker 7 (49:10):
Yeah, I just thought cool just to talk about the
laminate flooring in the bathroom Simon art sexual designer, and
I thought, yeah, just put in my two cents worth.
You might know Pete. A few years ago there's a
change of the Building Code E three and they decided
that laminate floorings weren't allowed in bathrooms. It's going to
be an well became an alternative solution. So the only

(49:34):
acceptable solution under the Building Code at the moment for
bathrooms wet areas pretty much vinyl and tiles. And when
you go to these laminate floors, they've actually included now kitchens.
A lot of people don't realize as the wet area
and nightmare. It's crazy. And I'll tell you what the
problem is in a way that the laminate floors are

(49:56):
going to be really careful. So a lot of the
reputable flooring companies don't advise putting it in bathrooms. It
can be more of a headache. And look, I've running
issues of laminate floors and bathrooms. Look, you could do
your best to try and waterproof them, you know, by
putting PVA glue down the seams and ceiling off around
the edges and all the rest of it, but you can't.

(50:18):
They don't work well over a because they're floating, right.
They don't work well over the top of a waterproof
membrane because what can happen is if I don't know,
if you ever noticed that if any water moisture, anything
gets underneath in between the bottom of the laminate flooring
the top of the waterproof membrane, it'll stay there. It'll
just it'll spink you. It can create all sorts of problems,

(50:42):
especially in bathrooms and toilets, you know, for obvious reasons.
You know, you've got kids and they miss the toilet
completely and it gets underneath and I can can stincter,
you know, and you'll never get rid of it. You
have to rip it all up. So, yeah, they're pretty problematic.
And you can imagine you step out of a shower.
People are soaking wet a lot of the time. There's

(51:04):
no tail, they're no match, and the water just seats
on that floor and you can see how it can
get down into the scenes, can't you over time, do
you sort of agree that you've probably seen people going
away because of the changes in the building code, going
away from lemonade floors.

Speaker 6 (51:20):
And.

Speaker 5 (51:22):
I mean, I think like typically for I mean, look,
there's still plenty of if we're going really old school, right,
if you're in an old cary villa or a bungalow
and that sort of thing, and you've got really nice
timber floors and you want to keep that in the bathroom,
then I mean you can get compliance with I think
it's three coats of polyurethane, right, Is it going to

(51:45):
be as durable as a waterproof surface with tiles over
the top of the POxy group? No, it's it's not,
but it's it should be generally Okay, adding a laminate
floor into a bathroom? Are there some risks here? There are?
Can you get compliance? Or obviously you can through the acceptable.

Speaker 7 (52:02):
Solutions alternative solutions.

Speaker 5 (52:06):
Terms of solutions rather, Yeah, yeah.

Speaker 7 (52:08):
It can be problematic. What people The problem is a
lot of people treat the flooring, even laminate floors, like
their carpet, don't they They don't really think about the
compliance side. I think a lot of the time I've
had clients that they'll go out and buy their flooring
from Bunnings somewhere, and they won't realize that it has
to be an alternative solution and have all the documentations
to prove it's waterproof. And then they put it down.

(52:31):
The council comes along and they see that they've used
a different one with the one that's been specified on
the plans, and it's a bit of a nightmare. And
people have even tried to circumnavigate by by putting down vinyl,
get the sign off from council.

Speaker 5 (52:44):
And then putting something over the top.

Speaker 7 (52:45):
Oh yeah, so it sort of promotes though rule breaking,
doesn't It so became overly onerous. And this is what
where we're at now.

Speaker 5 (52:54):
Where I encountered it doing sign off in a couple
of buildings is a concrete slab, right, So kitchen on
a concrete slab and then not being able to use
laminates within a certain distance and kind of go okay.
So if the intent of the legislation is to protect
from damage, you know, which is reasonable. But it's a
concrete floor, right, So if the dishwasher leaks over a

(53:16):
period of time, what's the worst thing that's going to happen?

Speaker 2 (53:18):
The concrete floor is going to.

Speaker 5 (53:20):
Get a bit wet, right, you know, so what are
we actually trying to protect here?

Speaker 7 (53:23):
But you're yeah, concrete floors are generally not not not
an issue. If you're you're on great, But if you're the.

Speaker 5 (53:36):
Regulation is still applied. Right, So the regulations didn't allow
for the fact there's concrete floor. You still have this
whole thing around waterproofing and protection from moisture and all
the rest of it.

Speaker 7 (53:44):
You can kind of go, you do and and and
it doesn't cover failures in your appliances. It's more to do.
But you know, things like your kitchen sink over flowing
and water splash, which there's minimal in a kitchen anywhere,
so it never should have been broad in the kitchens, Yeah.

Speaker 5 (54:03):
That's right, and things like laundries, you know where suddenly
it was one point five meters out from the water
source and the laundry, which yeah, again caused me all
the headaches.

Speaker 7 (54:14):
Not to worry that one thing quickly, one thing you
get who brings who brings in these bloody rules? Are
you able to get the person and find that person?
And can we have a conversation, Pete, because honestly, where
do they come from. They're ridiculous.

Speaker 5 (54:30):
No, Inevitably it won't be one person, right. I suspect
that what, well, what it is is it all goes
to No, it all goes to mby, right, and then
within mby there are those that create the legislation generally
by committee and all the rest of it. And I

(54:51):
suspect that lots of people within sort of the building
sector look at that every now and then and go
what the hell were they thinking? I still can't believe
that when they introduced the changes to H one with
the schedule method, that they went for a flat R
six point six right on the schedule method.

Speaker 2 (55:10):
Crazy, didn't make any sense.

Speaker 5 (55:12):
Then thank goodness they've ditched it now. But again hard
to be hard to go back. Oh mate, absolutely, who's responsible?

Speaker 7 (55:23):
Are they going to keep there?

Speaker 2 (55:24):
No, there's no responsibility, not not crazy.

Speaker 7 (55:28):
There's no accountability, is there. It's like, oh, well, you know, yeah, we.

Speaker 5 (55:31):
Introduced it, crack out, it didn't work. Everybody told us
it wasn't going to job, and now it didn't work,
and now you guys can sort it out.

Speaker 2 (55:40):
I mean, they need to know more.

Speaker 7 (55:42):
Cowboys website to lead.

Speaker 8 (55:47):
Yea saying that you know.

Speaker 5 (55:48):
It's also not fair to sort of dump on them
in the sense that I was at a seminar recently
with a couple of people who were presenting, and they
were from himbe talking about updates the building co. You know,
they're super well informed and so on.

Speaker 2 (56:02):
But I don't know.

Speaker 5 (56:03):
Every now and then. I think when you get a
group of people together, you just in it with a decision,
and that six point six was a bad decision. Oh
eight hundred, thanks Steve. Always good to talk with you.
Oh eight hundred eighty, ten eighty. We're talking all things
building and construction. If you'd like to join us, and
I'd love it if you did. The lines are open.
The number is eight hundred eighty ten eighty Beck with
Jan after the break.

Speaker 1 (56:24):
Mat or twice God once, but maybe call Pete first,
be your all keV the Resident Builder news Talks, they'd be.

Speaker 5 (56:32):
Your news talks. The'd be twenty four minutes after seven.
Remember we've got live coverage of the All Blacks versus
a lost Womas in buens Aires that's on later on today,
kickoff just after nine o'clock. Coverage starts from eight forty five,
So Rude will be here just a little bit earlier today, Jane,
A very good.

Speaker 12 (56:51):
Morning to you, very good morning to you.

Speaker 8 (56:54):
Also than thank you.

Speaker 13 (56:57):
Right now we're looking at buying approximately eighteen year old house.
Yes it's got a double glazing in it, but it's
got the brick read alumini. I know, we don't and yeah,
you know the look of it.

Speaker 5 (57:15):
Yeah no, and look with a gross respect to you know,
people like to express themselves and you know, maybe there
was a delightful architectural feature about it at the time.
But I can understand too that you'd look at it
and go, I love the house. I'm just not sure
that I can live with the joinery color exactly exactly.

Speaker 13 (57:35):
So I've looked up a few companies and everything like that.
Have you had any experience in recoloring them? Does it work?
Does it you know? How long for guarantee or how
much does it cost to replace the joinery?

Speaker 5 (57:52):
I'll look replacing it, well, theoretically there'd be a small thing.
It would be a tremendous job to replace it. Right,
there would be some benefits because chances are the aluminium
jowinery is standard eliminium joy so we have issues with
thermal break and the performance and all the rest of it.
But in terms of recoloring and doing it well and

(58:16):
doing it so that it's going to last. Basically, I
would just get in touch with Nanoclear, so in a
in O clear Nanoclear, talk to Daniel, get them to
come out and they're around the country. He can help
you out. And I've i mention it because it's it's

(58:38):
basically the only company that I've been to where I've
seen what they do in terms of the prep, understand
a little bit about the products that they use and
the warranties and guarantees that they offer. So yeah, if
you're going to do it, have a look at Nanoclear, okay.

Speaker 13 (58:52):
And they do the inside as well as the outside.

Speaker 5 (58:55):
They can do the inside as well. So pull the
glass out, take all the beads out, prep the frames properly,
paint inside and outside, coat it with a Nano clear.
If the rubbers are starting to deteriorate a little bit,
they can upgrade the rubbers, check all the hardware, put
the double glazing back in and it'll be quite the transformation.

Speaker 13 (59:16):
Oh okay, then all right, Oh thank you so much.

Speaker 5 (59:20):
Alrighty, good luck with that.

Speaker 7 (59:22):
Take care.

Speaker 5 (59:24):
I was watching one of the Grand Designs transformations the
other day. It was the Australian series, and they had
like a nineteen fifties house which was a real classic,
you know, early modernist, fantastic architecture, and they had they
picked out the window frames like in blue and different colors.
I quite liked it as an example of that time

(59:47):
and so on. Would you do it today? Maybe not,
but it looked quite funky. Actually, oh, eight hundred eighty
ten eighty is that number to call? Oh, I'm wondering
whether we should get Storm back on the show. So Stormharton,

(01:00:09):
who is a basically ventilation expert, she was on the
show a little while ago. I think I'm going to
have to get her back because we've had so many
texts about the sort of the standard sop right, standard
operating procedure for working your bathroom. Do you turn the
fan on as soon as you go into the bathroom?

(01:00:30):
Do you leave the fan off until you've finished the shower?
This part of me where that doesn't make sense, like
why allow all that moisture to collect and then try
and scoop it out at the end. Anyway, I'm going
to find out, I'm going to come back to you
with the proper, proper scientific no how on this next week,

(01:00:54):
heater first, then the fan when finished. I always do this,
never a misty mirror, says a texter. Oh, here's hopefully
some Hey, do I need a special paint to paint
on a PVC downpipe off the guttering? Thanks from Barney
Well special paint. I've had pretty good success with just lumbersider.
So if I'm painting the exterior of the house, typically

(01:01:15):
I'm using lumbersider, and that'll go straight onto the downpipes
as well if they're you know, typical sort of Marley
PVC downpipe. The lumbersider might need two coats, but sticks
like the proverbial. Oh eight eighty the number to call Michael,
good morning, Yeah greetings.

Speaker 14 (01:01:34):
Pretty little bit of out left field, but yeah. So
twenty five years ago I laid down a concrete slab yep,
and then I relocated a shed onto it.

Speaker 7 (01:01:53):
Yes, and.

Speaker 14 (01:01:57):
For the bathroom, made a little bit of an indentation
in the in the concrete so that the water would
flow down to a to a you know, so would
go out out and brought up five kids and still
the concrete said nothing. Nothing on the floor, no.

Speaker 8 (01:02:21):
Other than concrete.

Speaker 5 (01:02:23):
So when you did the concrete floor, did you apply
any sort of waterproofing to the mix or apply a
sealer to the concrete floor later?

Speaker 2 (01:02:31):
No, nothing interesting.

Speaker 7 (01:02:34):
What it did use was age three I think on
the the bottom plate.

Speaker 14 (01:02:40):
Yep, yeah, yeah, and yeah, and that's all. And it's
lasted me so far twenty five years.

Speaker 15 (01:02:50):
It's a bit cold in the winter, yes, when you
put your foot down, but yeah, so so nothing cost
me nothing either, So I'm not quite.

Speaker 5 (01:03:03):
Yeah no, I mean, look, it's it's like you'd struggle
to get compliance for it today and all the rest
of it. But I love the fact that you've done
it and it's worked and it's lasted. And what's also
just by the bike quite intriguing is one of the
jobs that I looked at this week was to upgrade
some changing rooms at a boys' school, boys secondary school

(01:03:25):
there from the nineteen nineties. You know, sort of an
old fashioned shower stall with a bunch of showers that
just you know, heads that hang down from the ceiling
and onto a concrete slab and an open drain and
that sort of thing. And we're thinking, oh, can we
do something a little bit better here, and I was
looking at you because we've got a budget for the

(01:03:46):
sort of work. Can I do some individual showers, but
still keep the concrete floor. And if I'm going to
do the concrete floor as the shower base, can I
add some waterproofing to the mix, or can I apply
a seiler? But I don't want to have to put
a secondary membrane over the top of it, because that's
all maintenance. So interesting to hear you saying, look, I've

(01:04:06):
done concrete as my shower base and it's worked. So
that further confirms that I might be on the right
track in terms of doing something that's going to be
robust but practical and will last for a period of time.
I'll let you know how I get on. Michael, thank
you very much for your call. If you've ever if

(01:04:27):
you've done concrete, you know, for sort of changing rooms
and that sort of thing, and you've added a mix
to it to help make the concrete water proof, let's
say flip met quick text and let me know what
you used. Eight hundred and eighty ten eighty is the
number to call. We've got a break coming up. We've
got some spear lines as well, so I had a

(01:04:48):
moment yesterday that was that was incredibly exciting for me,
and I just thought i'd share this because it started
with a boo boo on my part. Right, So the
other when was it maybe last week sometime I'd finished
a project done all the carpentry would work part of it,
and I was painting the last part of an exterior
balustrade so that I could pull down the scaffolding and

(01:05:10):
kind of wrap that job up. So while I was
on the ladder painting the veranda posts top coat. You know,
I'm on the ladder, I've got my brush, I've got
my little two lid pot in one hand, and I'm
reaching out and I'm sort of twisting around, and I
was listening to some I might have been listening to
some music or a podcast or ZB or something like

(01:05:32):
that with my old ear pods in right, And as
I tilted my head, the ear pod from my left
ear dropped and with precision that the dam busters would
have been happy about, the ear pod dropped straight into
the top of the paint in my two lid pot.

(01:05:54):
Now quite like, oh, there's a color amusing. I think
it's seafog, but I don't know that it goes particularly
well on EarPods. So anyway, there I am on the
ladder with a paint pot, staring at my earpod floating
around on the top of the paint, thinking well, I
was thinking a lot of things that we can't say
on air Anyway, fished it out, covered in paint, got

(01:06:20):
down from the ladder, thought about finishing the painting, thought that, look,
I hosed it down right. So I just hosed the
AirPod down. I put it in the sun to dry,
hoping that it would be okay, and I left it
there for a while, and then I tried it and nah,
dead as a doornail.

Speaker 2 (01:06:42):
And I'm thinking.

Speaker 5 (01:06:45):
They were my good pair, right. They're not the ones
that I usually use when I'm working outside if I
don't have to wear my muff Deique ear muffs. Anyway,
it sat on my desk. I charged them up again
the other day, and then I thought about how do
I get rid of them? Because they're ruined now, right,
But they've got a Liftian mind battery in them, so
I don't want to put them in the recycle. So
I started to think about where I can take them

(01:07:05):
so that they're disposed of correctly, and all the rest
of it, and then yesterday was just that last last
faint ray of hope. I popped them in and it works.

Speaker 2 (01:07:18):
It worked.

Speaker 5 (01:07:19):
I'm sitting there going hallelujah, Thank goodness, so my AirPods
worked again.

Speaker 2 (01:07:25):
They didn't work.

Speaker 5 (01:07:26):
They must have taken a while to dry out. But
anyway they've worked. Fingers crossed, they'll they'll stay working. Oh God,
talk about happy days yesterday. Oh anyway, don't wear your
ear pods. If you're shaking your head above a paint pot,
I can tell you that. Oh eight hundred eighty ten eighty.
We're gonna take short break to Pete. After the break
doing of.

Speaker 1 (01:07:46):
The house sorting the garden, asked Pete for a hand
the resident builder with Peter wolfcap call eight.

Speaker 5 (01:07:55):
A couple of quick texts and response to my aarpod story,
same thing happened to me, only in the airport in
the toilet. Eventually it did spring back to life, but
it did take a little while. Put the ear pods
on dry rice for a few days. It helps with
the drying out. That's very clever. I should get some shocks.

(01:08:15):
They must be like over are ear pods. A couple
of people have sent me this is the open run
sort of wireless ones. Yeah, I was actually looking at
the look. Typically, if I'm working and there's noise, I've
got ear muffs on, right, and I've got muff Tech
air muffs. I brought them a little while ago at
the Wellington Home Show, and they've got Bluetooth connectivity and

(01:08:38):
so I can listen to podcasts or whatever I happen
to be listening to that way, and they're super comfortable,
and that's great. But in this instance, it was just
painting that's not terribly noisy. I'd done all my sanding
and so it's a bit more lightweight to just wear
the old Apple ear pods. But thankfully it came back
to life. Actually, lots of people put the air pod

(01:09:02):
in rice in a hot water cupboard for a couple
of days to draw out any residual moist. I have
done exactly the same as an into a pot. I
don't know that it was the immersion in the raisine
sonics sea fog that I was painting. I think it
was probably the fact that I hosed it down with
the tap to get the water off. I just figured
I'm not sure that I've got it in me to

(01:09:24):
spend ages sort of wiping it down. Plus I wanted
to finish the painting, so I just grabbed the garden
hose and boughted it down. I figured, well, either the
paint's going to stuff it or the water's going to
stuff it, but I may as well get the paint off,
and they sprang back to life. I have to say,
I'm just delighted that they did.

Speaker 2 (01:09:40):
Peter, talk to me about your garage floor.

Speaker 12 (01:09:43):
Yeah, good morning. Can I really enjoy your program?

Speaker 5 (01:09:45):
Thank you much appreciate it.

Speaker 12 (01:09:46):
Hey, I've got a thirty year old sea declared sectional
garage door. Yes, and the seed has failed to the point,
and the glue and the and the whatever tacher has failed.
I've replaced both springs on it, and that's got a
new motor in the frame. Sign you're an option of
just replacing the panels.

Speaker 2 (01:10:07):
Yep, absolutely.

Speaker 5 (01:10:09):
I mean look in the end, they were fitted in
the factory originally, right, So essentially you're just redoing what
was done thirty odd years ago. Would you look at
doing it yourself? Sorry, would you look at doing it yourself?

Speaker 12 (01:10:26):
Yeah? I could do, or I certainly have a look
at that.

Speaker 5 (01:10:28):
Yeah, So when you Look, when you're standing on the
inside of the garage door, you've got the metal frame.
Does it have like plywood sheathing and then the ceedar
fixed to it? Or is the ceedar fixed directly to
the metal frame?

Speaker 12 (01:10:40):
It's got a little yeah, piece of plywood sheating that
attaches to the middle.

Speaker 5 (01:10:48):
Right, Okay, do you think that when you take the
cedar off the outside the plywood would still be intact?

Speaker 12 (01:10:57):
Yes, it would be because the pots and the plywood
doesn't go with it.

Speaker 6 (01:11:02):
Right.

Speaker 5 (01:11:03):
Okay, Look, it's all doable. Right if you wanted to
do it yourself, then yeah, I think you probably could.
It's it would be a little bit time consuming, but
it's just it's one of those things. It's just patience, right,
getting the old seedar off, prepping the substrate, finding the
new boards. You know, if I was going to reinstall

(01:11:25):
seedar onto a garage frame door frame like that, I'd
be ceiling both sides of the seedar before I installed it,
so rather than just putting a coating on the outside
once you've actually finished the installation, how how was the
original sealer seedar rather actually fixed?

Speaker 2 (01:11:45):
Is it pins or screws or it's pinned.

Speaker 5 (01:11:48):
It's pinned. Okay, so you would do the same thing
some stainless steel brads pinnate it is there some glue
as well?

Speaker 7 (01:11:56):
Yeah? Okay, would I have an option of.

Speaker 12 (01:12:03):
Buying panels and you know, something a little bit more
moral modern, but also something that I can put some
insulation and.

Speaker 5 (01:12:12):
Sort of upgrading the door.

Speaker 12 (01:12:14):
Upgrading the door.

Speaker 2 (01:12:17):
Yes, theoretically.

Speaker 5 (01:12:18):
I mean, look, off the top of my head, I
don't know anyone who would do that sort of work,
but I do get a sense that there will be
people out there that do it, whether or.

Speaker 7 (01:12:28):
Not I've asked.

Speaker 12 (01:12:30):
I've got quite a new door saying well, they are
just saying no, no, we won't do that. We just
supply doors. And I'm going, well, you know, on a
recycling basis, you know, there's a whole lot of stuff
that's going to be to go to a metal recyclerst yes,
as opposed to being able to reuse it, which there's
nothing wrong with it.

Speaker 5 (01:12:49):
Whereabouts in the country.

Speaker 7 (01:12:50):
Are you in Auckland?

Speaker 5 (01:12:52):
You're in Auckland. Okay. Look, if someone who is listening
who does this sort of work wants to text me,
I'm happy to read that out. So stay listening for
the next. Someone's got to do it within the next
thirty minutes, right, So if you can stay tuned ntil
eight fifteen or thereabouts or longer obviously because we've got
the rugby coming up at nine o'clock. But by all means,

(01:13:14):
if someone wants to text me, because I'm sure I've
seen some companies out there that do this sort of work,
and I agree with you. I think that you're taking
the right approach that it is. I get that, you know,
a garage door company wants to sell you a new
garage door. I get that, but you're you're right to say, look,
here's a door that basically is sound, but the surface
has deteriorated. So can I keep the frame, the hinges,

(01:13:38):
the hardware and all the rest of it and simply
refurbish the door. Yeah, of course you can. So if
someone wants to text me, I'm happy to read that out.

Speaker 7 (01:13:46):
Yes.

Speaker 2 (01:13:46):
Hey, thanks ver much much appreciate it.

Speaker 5 (01:13:47):
All the best to you, Peter, take care. Yeah, if
you are doing this work and you're good, then by
all means, text us nine two nine two and happy
to pass that on to Peter. Oh eight hundred and
eighty ten eighty the number to call quick text as well. Hey,
what's the theory on having to get a building consent
to insulate an outside wall nexterior If I had the
jib off the inside wall, the inside of the exterior wall,

(01:14:11):
my nineteen sixty six house, a very fine year, by
the way, that has no insulation in the outside wall,
I would fit the right insulation while I had the chance.
Why would I pay the council.

Speaker 2 (01:14:20):
For the privilege.

Speaker 5 (01:14:21):
We need to push it so it moves to schedule
one from Tony, Tony, I agree with you. I think
that this is something that should have gone to schedule
one of the building at which sets out work that
can be done without necessarily requiring a building consent. My
understanding is that it requires a building consent because in
some instances, if this is done wrong, the wrong type

(01:14:45):
of insulation is used, it's installed incorrectly, it can actually
bring more moisture into the building envelope right, So it
creates a bigger problem than a lack of insulation. If
you've got a lack of insulation, typically in an old house,
you'll have a bit of drying that will happen, ventilation
that will happen, so moisture is mana by the fact

(01:15:07):
that it's drafty. It's an old phrase for old houses
drafty but dry. So if you then put insulation in
and you block that potential for drainage or ventilation, then
you can introduce moisture and you get mold and you
get rot. And that's why I think they've kept it

(01:15:27):
as it requires a building consent just so people do
it right. I think that that is exactly given the
desperate need to get more insulation into our houses and
the amount of houses that are still partly uninsulated. That
number is dropping, but there's still a number of houses

(01:15:47):
that need retrofitting of insulation into exterior walls. It should
be moved to Schedule one and it should be done
or supervised by an LBP so that there's a record
of work for it, there's evidence that there was planning
and you know, some sort of advice, some sort of
analysis of what the problem, how are we going to
fix it, here's my solution, and here's a record of it.

(01:16:10):
But yes, I agree with you, Tony, it should go
to shed you one of the act. Maybe when the
minister's here next week I can have a chat with
him about exactly that. Not next week fourteenth or September
at the stages. Whereas when we're talking about possibly having
the Minister Chris Pink come into the studio for a
bit of a chat again, and I promise you when
he does come, i'ld chat for a bit and then

(01:16:31):
we're going to open it up to texts and you
can ask the Minister your questions as well, and I'll
stop hogging the time. Oh eight hundred and eighty ten eighty,
will do we have another break?

Speaker 6 (01:16:42):
Yeah, we do.

Speaker 5 (01:16:43):
Let's take a break. Then we'll talk to Dean.

Speaker 1 (01:16:45):
Whether you're painting the ceiling, fixing the fens, or wondering
how to fix that hole in the wall. Give Peter
wolf gafacall on, the resident fielder on Youth Dogs' b.

Speaker 2 (01:16:57):
First text come in.

Speaker 5 (01:16:58):
With regard to the garage door. We'll mention that in
just a moment, Dean, good morning to you.

Speaker 16 (01:17:04):
Indeed, we have a s in our on suite and
there's a gap between the plastic floor pan I suppose
and the lovely plasticall feating and we fill it from
time to time and get it filled with some sort
of ceiling, this gap between the two of them, and

(01:17:25):
it always just colors, even if we get mold resistant
blah blah blah blah blah, And it makes me think
that there's possibly a leak going on there anyway. So
without having to replace the entire shower, I was thinking,
as you do in the shower, there's such a thing

(01:17:45):
as like a plastic strip or something you can buy.
It goes between the plastic wall lining and the plastic
shower pan that you can.

Speaker 5 (01:17:54):
Apply to cover that, to try and seal that or yeah.

Speaker 16 (01:17:59):
I've seen that obviously isn't doing the job. I mean,
if it's just coloring, it's to me that implies this
water getting into it too much. You know, I'm not
a plumber, I know.

Speaker 2 (01:18:08):
Yeah, I suspect.

Speaker 5 (01:18:11):
I don't know if you're saying that there's water getting
in it.

Speaker 2 (01:18:13):
I mean the fact I know that there is.

Speaker 16 (01:18:16):
I mean, it's just that this the silicon is supposed
to be anti mold.

Speaker 5 (01:18:19):
Yeah I know. Yeah, and it's just coloring, right, It
makes I pulled out some sealant that was put in.
I know, because I basically was there when they put
it in. In twenty twenty, A bead of sealant between
the vanity and the tiled splash back, let's say, and
again you know this is it's a vanity, right, so

(01:18:42):
it's not even in the bowl as such, mold all
the way through it. And I thought, I'm sure that
we use you know, anti mold sealant. So again, happy
to take a text from someone who goes, I've actually
used a product that says it's anti mold that actually
is anti mold. But that's a separate matter. The other
thing that I want to point out because I know
that this is a common issue with that type of

(01:19:03):
shower installation. So you've got a train which is fitted
onto the floor and pushed hardback against the timber framing.
Typically your lining comes that, your substraight lining comes down
and then there's an upstand on the tray, and then
your internal lining sits down over that, so it seals
the gap by having an overlap, right, And when you

(01:19:26):
install that shower lining, where you should apply the sealant
is at the top of the upstand of the tray,
so that when you push the lining against it, it
seals and stops moisture tracking up and over the upstand.
But you don't have the sealant visible from the inside.
So that's how it should be installed. So if you

(01:19:49):
don't put the sealant there and then you whip a
bead of sealant around later on, then that is going
to be a problem because it's constantly exposed. So the
other thing to try is to use some silicon removal
And I got a foam the other day that I
found it one of the large hardware stores. So again

(01:20:10):
on this vanity project, I had to replace the tap
the other day, so while the tap was out, I
took the opportunity I use this silicon removal foam like
a spray that goes on and then I stripped out
the celant, let it dry and replace the celant at
the same time as we replace the tap. Is you
could try and use this foam to remove or the

(01:20:31):
spray to remove the sealant, and don't put any sealant
there because it doesn't If there's a bead of sealant
higher up, that sealant is not doing anything.

Speaker 16 (01:20:41):
Anyway, right, gotcha?

Speaker 5 (01:20:44):
But I guess the question is if there isn't a
bead of sealant further up, then you know potentially you've
got an issue there. But that's not where the sealant
should go. Anyway, so I just remove it and see
what happens.

Speaker 16 (01:20:58):
Excellent.

Speaker 7 (01:20:59):
Yeah, so as far as.

Speaker 16 (01:21:02):
They'd say, for agurent sake that we decided that it's
not been installed properly, you can take those plastic walllining
very very basically for another one of those.

Speaker 5 (01:21:14):
Ye yep.

Speaker 7 (01:21:15):
Excellent.

Speaker 5 (01:21:16):
Okay, good luck with.

Speaker 7 (01:21:20):
I really appreciate you.

Speaker 5 (01:21:22):
Hey, look, I don't want to do anyone out of work,
but sometimes there are other solutions.

Speaker 2 (01:21:28):
Nice to talk with you. Thank you very much.

Speaker 5 (01:21:30):
You take care, Dean. We'll talk to Shane after the
break because we're rushing up to New Sport and we're
the top of the hour, which is awesome. So I've
just had this text from Jacent at Kinetic Excess Garage Doors.
They're in Auckland and christ Church. You can find them
online Kinetic Excess dot co dot m z. And he

(01:21:52):
might have a solution for Peter who wants to replace
the exterior seedar on existing garage door because it's wasteful
to throw it away.

Speaker 12 (01:22:03):
Right.

Speaker 5 (01:22:04):
Talking about waste, and I've I see that brands have
just done their annual report and they've got some waste analysis.
I had a long conversation with someone who works heavily
in the sector. That's going to be a bit of
a focus over the next couple of weeks for me too,
as we need to start talking rubbish. I know the
text will come through, mate, that's all you talk, but no, seriously,

(01:22:27):
waste and the amount of waste created from the construction
sector is unbelievable, so we need to do something about that,
so we'll talk about waste as well on the show.
Remember Rood's going to be here early. We've got the
rugby after nine o'clock.

Speaker 2 (01:22:41):
Squeaky door or squeaky floor.

Speaker 1 (01:22:44):
Get the right advice from Peter Wolfcare, the resident builder
on news Talk.

Speaker 5 (01:22:48):
Semb right, Oh, welcome back to the show. Eight hundred
and eighty ten eighty is the number to call. We'll
talk building for just a little while. Then we're going
to bring rud in early because basically we're handing over
to the sports team at around eight forty six this
morning for some pre match coverage. Remember kickoff just after
nine o'clock here at Newstalk, said b Well, the game's

(01:23:10):
not here, the games in buddhist aaris. It is the
All Blacks versus Lost Boomers, the second Test match of
their Argentinian Tour. Live coverage here from just after nine
o'clock this morning. Getting some texts which is awesome about
the waste. So it's a whole topic for a whole
other day. It's a really really important topic. A pik

(01:23:35):
guy McKey at Boss Construction christ Church gets all of
their construction ways sorted and recycled where possible.

Speaker 2 (01:23:40):
Speak with them.

Speaker 5 (01:23:41):
More than happy to do that, Quinn, I'll talk to
a whole bunch of people. But what that text says
to me is that there are companies that are doing
it and it is possible, and I know it's possible
because I've seen it and I've done it, which also,
to be really blunt, says to me that if you're
not doing it, you're either ill informed, misinformed, ignorant, or.

Speaker 2 (01:24:02):
Just you don't care.

Speaker 5 (01:24:04):
And I don't think that's acceptable anymore to be blocked.
So if you're doing a renovation, you need to be
talking with your tradees. What are you going to do
with a waste? Where's it going? How are you managing it?
And if they go, look we just put it in
a skip and they take it away and they put
it into landfill, I don't think that's good enough anymore.
There you go, mixt you're over for the morning. I'm
pretty passionate about it. I sit on a board of

(01:24:26):
a recycling center for that reason. And I was sitting
in the traffic the other day actually, and there was
another trader ute next to me with a cage trailer
full of building materials, and I kind of assumed that
I know where they were going. They're going to hop
on the boat away. They're going to take that up
to landfill. And I'm looking at going. You know, like,
if you bought it to, for example, the Resource Recovery

(01:24:48):
Center in Devenport, we'd tip it out on the ground
we'd sought it, and we'd divert seventy six percent of
that material from landfill. So you can do it. You
just have to have the inclination to do it. And
I think if you're getting work done as a consumer,
you need to be asking your tradees what are you
do doing with the waste? And if they say we

(01:25:09):
just put on the skip and we don't care, then
I'd recommend that you talk to a different trading There
you go, Shane, good morning, Welcome, good morning.

Speaker 12 (01:25:19):
I'm a building inspector I've been inspected for sixteen years
and then and as a builder for thirty five years.
I've talked on side about this subject so many times
in the last sixteen years. Where you go to a
job they're doing a reno, they've ripped off all the
jib board and they're now stuffing bats in the wall.

(01:25:39):
But the problem is all old houses leak, and you
would have seen it yourself. Water stains down the back
of the weather boards and down the studs where the
water is driven in, but it's dried out the next day.
So what you said before about drafty in the walls
is really good.

Speaker 5 (01:25:54):
Now drafty but dry. Yeah, that's how you describe all.

Speaker 7 (01:25:57):
Yep, that's right.

Speaker 12 (01:25:58):
But when you stuff bats in or no, won't use
the word bats. Fiberglass insulation or a lot of insulation
in the walls, that is like a big sponge in there.
And if it does get windblown rain into past the weatherboards,
that's going to saturate the bats, which are like a
big sponge.

Speaker 8 (01:26:16):
It's like a.

Speaker 12 (01:26:17):
Dripping tap under a let's call them heads. Yeah, like
a plastic market under a dripping tap. Now, there is
a way of actually protecting the bats and that's by
encasing the insulation in the walls with building paper. Now,
the problem is, rarely have I seen that done profit.

(01:26:38):
They'll just stuff about the building paper and these are
qualified people, and then they stuff the bats in, but
that's not going to protect give a little raincoat to
deflect the water away from the insulation. The problem is
if you've got insulation and an existing wall, exterior wall
and it does leak, you've created taken you one hundred

(01:27:00):
year old villain to a compost heap within about five
years now, I didaborate with a guy who was doing
this thesis on insulation and we basically figured out that
most of the damage caused by in the leaky building
home or leaky building syndrome was probably the five or
pass insulation. Well, if you can, if you can, and

(01:27:24):
I know it rots really fast and stuff like that,
but when you trap water in the walls, you've you've
really created a huge issue. And this is why it
needs to be supervised by the council.

Speaker 5 (01:27:36):
Now in Shane, I don't disagree with you, but I
do want to say I don't think we should suggest
to people that the issue with leaky buildings is the
insulation right. The issue with leaky buildings was the water
getting in.

Speaker 12 (01:27:51):
Now I agree completely, Yeah, okay, but somehow it was
leaked in the past, but you exacerbate the problem when
you don't allow it to dry out.

Speaker 7 (01:28:03):
Yeah.

Speaker 12 (01:28:03):
So this is why all modern houses have around the
windows and building paper laps into the window openings to
try and make that one hundred percent waterproof. You can't
get that with an existing old house, true, unless you
take all the clotting off. So so much damage will
be caused to people's houses by inadvertently just trying to

(01:28:25):
insulate the walls to keep it keep it warm, But
that doesn't keep it dry.

Speaker 5 (01:28:30):
And I think that's why, and i'd agree with you
that that that's why it stays as work that requires
a building consent, because you can actually do more damage
to your house than good by installing insulation and not
thinking about the other things.

Speaker 7 (01:28:45):
I mean.

Speaker 5 (01:28:45):
The other thing is, and I've done itself, is we
use like a drainage material against the back of the
old weatherboards that allows for some ventilation. So there's a
damp product, so you put that on, then you put
your building paper in, you know, as neatly as possible,
and then you install your insulation. The other thing is
that different types of paired insulations are moisture phobic, so

(01:29:09):
they won't hold moisture. So still are concerned, but you
know there are ways around it. And I guess what
you and I are saying is you can do it,
you have to do it right. And because we want
to do it right, that's why government probably says it
still needs to have a building consent. I just look
at it and go it's the sort of work that
could be done under Schedule one of the act if

(01:29:31):
it was done by an LBP, and then you'd hope
that the LBP would know enough. I'm probably unrealistic in
my optimism, but that's one way of looking at it.

Speaker 12 (01:29:43):
Well, you are right in all the ones I've done,
and I've done a lot of intellections thirty thousand inspections
in the last sixteen years, and often no one's supervising
the young apprentice who's stuff in the billing paper and that,
And I would say in less than five percent of

(01:30:04):
cases that I've done in the sixteen years has the
actual protection of the insulation with building paper being done properly.
But your idea of putting an insulation pad which gives
insulation behind the weatherboard. It's just a fantastic idea.

Speaker 5 (01:30:21):
Yeah. No, it's a product called damp mat I think
it is, and there's a couple of other ones that
are coming out that essentially, you know, because I've seen
the pictures right where you go. What you do is
you stay with your building paper fifteen millimeters off the
back face and it stays perfectly straight and it allows
for drain that just doesn't happen.

Speaker 7 (01:30:41):
Right.

Speaker 5 (01:30:41):
You can draw it, but you can't do it. So
what this does is it goes. Actually what you do
is you apply this product. It's like a scouring pad, right,
So it's plastic that allows for a constant air gap,
and you just drape that across the back of the weatherboards.
Then you put your building paper on. It means that
the building paper doesn't crush or the insulation doesn't push

(01:31:01):
the building paper hard to the back of the weatherboard,
and that allows for some ventilation. And given that there's
probably air gaps in there anyway, so let's keep that
air gap. Let's allow the back of the weatherboard to
dry with the wind driven rain that you're talking about.
But we can add the insulation. But if you don't
know where, you're not told, or you don't have the

(01:31:23):
building science to understand what you're doing, then you're going
to get problems. And that's what you've probably seen.

Speaker 12 (01:31:29):
Well, you're right with the code. The actual wording in
the code is you need a building consent to retro
for insulation and the exterior walls of an existing house, yes,
for weather tightenness reasons. And that's that weather tightness reasons
that is the big deal. Because old house is more
than twenty years old or thirty years old are not

(01:31:51):
weather tight and you need that wind and air to
allow to.

Speaker 2 (01:31:58):
Rate draft get dry.

Speaker 5 (01:32:00):
That's the way it is. Hey, Shane, really appreciate your call,
and please call again because it's it's a great conversation
to have. But and look, it's one of those things.
It's a is it a desperate need? It's certainly a
fairly significant need. Right to continue to upgrade insulation in
existing houses. We've done the easy stuff. You can get
underneath the floor, sometimes you can get into the ceiling.

(01:32:22):
I mean I looked at a property this week that
had a skillion roof right nineteen seventies, probably no insulation
in there. So you've got a roof that. How do
you get insulation in there? You've got to pull the
roof off. You've got to pull the lining off. Either way,
it's a big job. It will make a significant difference
to the house. Thanks Shane for that much appreciate. A

(01:32:42):
couple of quick texts, Pete, do you know when the
new insualation rules the government announced will be coming in?
I don't they've announced it. I don't think it will
take effect until the end of next year. It's about
a twelve month period. This is for ditching the schedule
method for H one compliance and adopting either a calculation
or a modeling method. Halleluja your first time I've heard

(01:33:04):
someone agree with me reinsulation and a leak from Dennis Denis.
I'm not sure what it was that you agreed with,
but insulation and leakage or moisture and gress into a building.
That's why it's exempt from shed you. One of the
act why it still requires a building consent is if

(01:33:25):
you do it wrong, you're actually causing big problems. A
couple of people mentioned in st.

Speaker 2 (01:33:33):
Max again.

Speaker 5 (01:33:36):
Read the current talk show. I'm a Wellington resident. The
problem with recycling is they've got very specific rules. Yeah,
so what's the problem with that. They don't pick up
your recycling bin because the wine bottles had caps on it,
So take the caps off or is there a plastic
bottle that's not the approved type? Well, learn which ones
are approved and which ones aren't. And then they end
up throwing everything. We just end up throwing everything down

(01:33:56):
the regular bin. Well you're lazy, So sort it out,
figure out what they can recycle and do it properly.

very good morning to you.

Speaker 17 (01:35:40):
It's very very foggy in christ Church.

Speaker 14 (01:35:43):
It's beautiful here.

Speaker 17 (01:35:44):
Yeah, so I suggest that all the seventy eight point
nine percent of people that drive cars turned their free nights.
What anyway?

Speaker 5 (01:35:55):
Yes, hello, how are you people?

Speaker 2 (01:35:57):
I'm well that you and I both that's not.

Speaker 5 (01:36:01):
I started talking about recycling and waste and construction, and
obviously I've got some fairly strong opinions about it, and
I tell you what, that's going to be a topic
for the show for a couple of weeks time. But
I can imagine it is phenomenally wasteful. And I mean,
you know, you're driven by looking to protect the environment

(01:36:22):
from a nature point of view, and I've got a
similar event, but from what do we do with our
waste point of view?

Speaker 17 (01:36:28):
So, oh, the waste. That's totally totally correct with you
with that. What you were talking about is absolutely important.
And there were some really cool text messages as well,
which I think was nice.

Speaker 5 (01:36:40):
And look, there's options, right, there's options. There are so
many options, so that's great. Hey, look, I know we're
a little bit short on time today, so let's rip
into it. If you've got a question for it, please
give us a call now. Eight hundred and eighty ten
eighty is the number to call. You can flick through
a text on nine two nine two, and Philip, A
very good morning to you.

Speaker 7 (01:37:00):
Good morning boys.

Speaker 18 (01:37:02):
Hello, I have I go call when you any merry potatoes?
Oh yeah, they have a lot they have a lot
of eyes on them and a lot of sprouts. Yeah,
and I get up to about a meter and a
half above the ground of green. Should I take some
of those eyes off before I plant them?

Speaker 17 (01:37:23):
I would suggest let them go up and take them
off when you assess how many you actually want in
the end and how well they do, you know what
I mean. So this particular plant will probably say, look,
this is what I can do, but not all of
them I think would be would be great. So it's
just one of those things. Do you do you sprout

(01:37:44):
them above the ground or on the ground?

Speaker 7 (01:37:45):
What do you do?

Speaker 8 (01:37:48):
I spread them before planting?

Speaker 17 (01:37:50):
Yeah, of course, yeah, that's what I mean. So you
can then already indicate which one is strong and which
one works well, you know what I mean?

Speaker 8 (01:37:57):
Okay, right, and just what those weekly looking ones off?

Speaker 17 (01:38:00):
Yeah, just a sharp knave whoopie, goodbye, yep, Yeah, thank you, sir,
have fun. Yeah, good one that I.

Speaker 2 (01:38:13):
Colin?

Speaker 5 (01:38:14):
Sorry, not Colin?

Speaker 7 (01:38:15):
That was that was Who was it? That was Philip?

Speaker 2 (01:38:18):
Philip.

Speaker 5 (01:38:19):
That's right, he's gone, he's done. He sorted it is
no mucking around high quick text bes fertilizer for magnolia.

Speaker 17 (01:38:27):
Oh at the moment, I would just use a general
fertilizer nightro Fosco blue. If you want the granular, I
tend to use the Wait and forget sea weed.

Speaker 2 (01:38:38):
No seafood soup in this case, yep.

Speaker 17 (01:38:40):
But if they are not flowering too well, do the
seafood seaweed tea which is contains more potash if you like,
and that might stimulate flowering.

Speaker 2 (01:38:50):
Okay, brilliant, we can take short break.

Speaker 1 (01:38:53):
