Installing Window Trim (Jambs) & Casings

3 Materials
2 Hours
Window trim/molding is an easy project to tackle and it really dresses up the window. Either replacing old, damaged molding or putting up new, this project can make a big impact for very little money.
This is a new window, so what you're seeing is the window wrap before any trim or moldings have been added.
This is the window stool (or sill) that I used. It's the most expensive part of the trim. This is 3 1/4" wide (or deep) and the other standard width is 5 1/4". I went with this because I like the thickness of it and the front profile. It allowed me to keep the rest of the trim rather simple and I also didn't have to trim down the width. This was also a closer match to all of the other windows in my home.
Window stool installed.
Side jambs installed.
This is the trim piece I used for the apron below the window.

Finished trim/molding on bottom left of window.
Here's a picture of the full length of the window. I couldn't get a shot of the whole window because of the lighting. It kept coming out to dark.
