We’ve been meaning to add new trim to our window and slider but it took us a while to agree on a trim style. We eventually want to add new trim to all our windows and doors but for now we just installed it on two windows and two doors. We used PVC casing for the durability and low maintenance. It’s a plastic composite that feels and cuts like wood.

We designed our trim to look like a picture frame with mitered corners. We used 3/4″ x 1/4″ pieces and 3 1/2″ x 5/8″ pieces.

While Mike was finishing up the back door, I painted all the trim:

Luckily, Mike didn’t lose any fingers while cutting the small pieces:

We used a strong construction adhesive to attach the trim to the stucco. Attaching trim around the door:

For the slider, we had to cut the trim in multiple pieces to fit around the weeping holes:

Adding glue on the larger pieces:

We thought just pressing on the pieces for a few minutes would make them stay put:

However, we learned we needed blue tape, stone, and even a sledgehammer to help hold the pieces in the right position while they dried:

We had to get even more creative with the other window:

The mitered corners made it a little more difficult getting everything lined up. We added backer rod in any spots that had a gap between the stucco wall and the trim – mostly at the corners.

Besides painting, my other job was to caulk everything. It always takes longer than I expect. The picture frame design after being caulked:

Before & After pictures:

We still need to paint the stucco once we agree on a color. Overall, we’re happy with how the trim turned out and the low cost of about $100 per window/door. We’ll wait to see how it holds up for a while before adding it to our other windows and doors.
