Gary tackles two home improvement questions from listeners. First, a caller shares a concern about a stone step that's been damaged and needs repair, and Gary offers advice on how to fix it without replacing the entire step. Next, a caller asks about cleaning a sediment-filled hot water tank, and Gary provides guidance on how to safely drain and clean the tank. The episode also features a discussion about basement insulation and a product review of Roller Rock and Spread Rock coatings.
