Wooden Window Trim Ideas
- The most classically formal way to dress up a window is with a wide, prominent sill over base molding and fluted vertical spans on either side of the window, topped with crown molding. This configuration is a lot of work and expense, but for big windows in showcase rooms, it can be worth it. The most difficult part is getting the corner cuts right on the crown molding, which sits out from the wall and on an angle and requires a compound miter cut at each corner. Buy or borrow a compound miter saw and practice on scrap wood before you try it on your good molding.
- An easier variation on pre-milled crown molding and trim is to use milled corner blocks. These are flat squares of wood, generally about 5 inches to a side, with designs cut into the face of the block. You hammer one block to the wall off each corner of the window, then hang your four straight spans of trim between the blocks. The blocks become the corners, eliminating the need for any miter cuts while dressing up the window at the corners.
- For a small, out-of-the-way window that just needs to be finished with the wall, buy some flat beveled trim, about 2-1/2-inches wide. Measure each span of the window on the casing. With a miter saw, cut one piece of trim for each span, with the inside edge as long as your measurement and outside edge angled out at 45 degrees. Nail all four spans alongside the window, just covering the casing and the wall, with the 45-degree angles of each corner meeting to form 90 degrees, like a standard picture frame.
