How to Install Interior Door Trim

Installing interior door trim is a relatively simple project that can be completed in a few hours. By following these steps, you can add a touch of elegance to your home while also improving the functionality of your doors.

Materials You'll Need

Door trim molding
Miter saw
Nail gun
Finish nails
Carpenter's square
Tape measure
Level
Caulk
Caulk gun

Step 1: Measure and Cut the Trim

Begin by measuring the length of the door frame and cutting the trim to size using a miter saw. Cut the trim at a 45-degree angle on both ends to create a mitered joint. Use a carpenter's square to ensure that the angles are accurate.

Step 2: Attach the Trim to the Frame

Place the trim on the door frame and secure it with finish nails using a nail gun. Start by nailing the top piece in place, then the side pieces, and finally the bottom piece. Make sure to countersink the nails slightly below the surface of the trim.

Step 3: Fill Nail Holes and Caulk

Once the trim is attached, fill any nail holes with wood filler and allow it to dry. Then, apply a bead of caulk along the seams where the trim meets the door frame and the wall. Smooth the caulk with your finger or a damp cloth to create a clean, professional-looking finish.

Step 4: Paint or Stain the Trim

If you want to change the color of the trim, you can paint or stain it to match the rest of your décor. Allow the paint or stain to dry completely before using the door.

Tips for Success

Use a level to ensure that the trim is installed straight.
Make sure that the mitered joints are tight and flush with each other.
Counterbore the top of the nails slightly with a nail set to prevent them from splitting the trim.
Caulk all seams to prevent air and moisture from entering.

Conclusion

Installing interior door trim is a simple and rewarding project that can make a big difference in the appearance and functionality of your home. By following these steps, you can ensure that your trim is installed properly and looks its best for years to come.
