One podcast listener wonders if he should jack up his drooping joists or if he can just create a flat floor using tapered sleepers over the old subfloor.

On this week's show, Patrick, Matt, and Rob talk about rigid fiberglass insulation, saving energy with low-flow shower heads, and siding details on houses with garrison-style overhangs, before answering listeners' questions about leveling floor framing, bringing the grade up for an accessible entrance, and what books to read to become a better builder.
