How To Install Wood Trim On Interior Doors

Here are the steps to installing wood trim to an interior door.

  1. Choose the trim style that you like, if the door has trim already that you are removing choose a trim that is slightly wider that what you have. (This will save you a step or two)

  2. With trim removed you should see the jamb of the door. (The wood that surrounds the opening that the door fits into).

  3. The new trim will picture frame the jamb with a slight reveal of the jamb showing. Measure the top horizontal part of the door jamb on the inside corner of each side then add ¼” to the length.  This is the inside measurement of the cuts on each side.

  4. Place your trim on a miter saw and cut the first side at a 45-degree cut. Measure the short side of the cut to the length of the trim of the measurement you just took with the added ¼”. Make that cut you now have the top piece.

  5. Install the top piece of trim paying attention to that reveal on the jamb and nail it in place either with a power nail gun or hand trim nails.

  6. On the short side of the cut measure down to the floor and the right and left side and cut those boards at a 45-degree angle.

  7. Install the vertical boards in the same manner. If you are painting the trim, you can add caulking to the cuts and caulk the trim to the walls for a finished look.
