Window Class Back in Session | This Old House

31August 2020

There is a day in every This Old House apprentice's life when they learn to install a window. Today Kevin O'Connor finds Jeff Sweenor at the head of the class with apprentices Kathryn and De’Shaun soaking up the knowledge

SUBSCRIBE to This Old House:

Jeff Sweenor shows the apprentices how to fasten a clapboard to the sill for a pitch and how to waterproof the system with flashing tape. Then they apply a bead of caulk around the three sides but not the bottom so the water can go out from underneath. Then they use shims to lift the window a tiny bit to allow water to escape. Then the window goes in, bottom first.
