Norm and Tom install reinforced fiberglass columns to support the new farmer's porch. Richard meets plumbing contractor Brian Bilo and local plumbing inspector Donald "Duke" LaConte to see what he's looking for at our rough plumbing inspection. Kevin and Tom meet building commissioner Fred Lonardo to see what goes into the rough mechanical and rough framing inspections. After Fred signs off, insulation begins. Tom shows Kevin the storm window system he's using to enclose the screen porch, and Russell Parrot shows how we're going to heat the space: with electric radiant floor heat. Norm and Tom welcome back Fred Lonardo to review the various ways we can achieve the insulation value we need in our walls to meet code.
