WINDOW TRIM
Family Handyman
|September 2021
Installing wood trim around windows can be expensive and time-consuming. Drywall returns fix that. Most windows are installed using wood jamb extensions to finish the rough openings; these pieces extend the window jambs to the interior wall. Window trim then covers the jamb extensions, providing the finished and trimmed look we all know.

1 PREP THE ROUGH OPENING
Not all windows are perfectly centered in their rough openings. To center a window, you may have to shim the sides, top or bottom of the opening. You want an even reveal around the inside perimeter of the opening between the window and the drywall return. You can buy shims or make your own by ripping different thicknesses of wood. Attach the shims to the rough opening with staples or finish nails. Before finishing, always insulate around the window with spray foam or fiberglass insulation.
