Layered door and window trim molding
Want to upgrade your door and window casings without removing the existing trim? it’s easy to create custom casings by adding a second layer of trim – outside the existing one.
My Maryville, TN house had really narrow, basic casings on all the doors and windows. It’s a very big house and I didn’t want to have to remove ALL that trim in order to have more substantial casings. This method allowed me to create the bulky casings I prefer – without doing any demo.

I chose a molding that would work well with my existing trim. What I looked for:
- a molding that was slightly thicker than the outside edge of my existing trim.
- a rounded inside edge to coordinate with the rounded outside edge of the existing trim.
- at least 3/4″ (preferably more) thickness on the outside edge of the new molding. I tend to add railings, planking, and other wall treatments and I prefer to have them terminate into casings which creates a cleaner, professional, well thought out look.

I installed the new trim with mitered corners just like the original casings were installed. Once painted, it looks like one big, bulky, expensive door casing.

I did have to remove the baseboards because there wasn’t any way to work with those 3″ throwaways but the doors and window casings are perfectly satisfactory with the additional layer of trim.




You really do a beautiful job on the mitered corners! Your molding is just perfect and really makes a statement!
I am showing my husband this right now! Cant wait for him to do ours as well as crown molding and baseboards! Looks great!
For your closet(?) door near the corner, are you leaving that as is because there’s not enough room for more trim? I have that situation for quite a few doors in my house. I could add to the top but not the sides.
I actually love that look, we started doing that in our 1/2 bathroom by mistake. I love it so much that I’m going thru the house little by little and beefing up the rest of the window casings where I can. 🙂 Love it!
Are you going to do this trim around all of your doors in you house?
