Sound Proofing Your Bathroom + How To Paint Your Garage Door + Walter Mosley’s Los Angeles

This week on This Old House Radio Hour, we meet Bo Petterson—a 66-year-old dad, DIYer, and unexpected TikTok sensation. Known to millions as @DadAdviceFromBo, Bo began posting home repair videos with his daughter Emily as a way to help her recover from a traumatic brain injury. What started as a private act of love has grown into a viral force for good, offering step-by-step repair tips, emotional support, and the quiet reassurance that it’s okay not to know everything.

Then in *My Old House*, acclaimed author Walter Mosley returns to the South Central Los Angeles bungalow where he grew up—a 1,500-square-foot home filled with fruit trees, family, and the kind of detail that shaped his voice as a writer. With warmth and reflection, Mosley explores the power of place, the meaning of identity, and the memories that never leave the walls we call home.

Plus: your DIY questions, a round of *What’s That Sound?*, the surprising history of toilet paper etiquette, and Mauro Henrique’s clever painter’s tape workaround you’ll want to try this weekend.
