Contractor Frank Di Leo shows you how to add architectural interest to your windows with an inexpensive, impactful project that anyone can do!
MDF (1/2 or 5/8 in. thick, 3 1/2 in. wide)
your choice of paint
- Frame window with MDF as though installing regular/standard casings. Make sure to glue strips down first before nailing them into place.
- Using a table saw, cut MDF into 7/16- or 3/4-in. strips. (Alternatively, you can buy prefab trim at your local hardware or home-improvement store.) Measure width of window (including casing) and cut 4 pieces of trim to fit.
- Run a bead of glue along top edge of top casing. Affix trim and nail into place. Repeat along bottom edge of top casing and both edges of bottom casing.
- Measure vertical distance between trim on top and bottom casings and cut 4 more pieces of trim with which to frame left and right casings.
- Run a bead of glue along left edge of left casing. Affix trim and nail into place. Repeat along right edge of left casing and both edges of right casing.
- Once trim pieces have been nailed and glued in place, it's time to install the block details that will give the window its architectural depth. Measure distance between the strips of trim that you have installed along the edges and cut square blocks to size out of leftover MDF. Install blocks at all four corners and symmetrically along casing as desired.
- Sand rough edges, caulk all joints and fill nail holes with wood filler.
- Prime, paint and admire your work!
