House construction follows standard procedures, starting with excavation that's followed by foundation construction; floor, wall and roof framing; the installation of sheathing and protective surfaces to close in the roof and the exterior walls; the installation of plumbing, wiring, ducting and other infrastructure; the installation of interior surfaces and fixtures; and finish work including painting and trim work. As soon as the wall and roof framing is in place, it’s essential to close in the exterior to achieve a weather-resistant shell before you move on with the rest of the home construction.
