Replace Interior Door Trim: A Comprehensive Guide to Refresh Your Doors

Interior door trim, also known as casing, frames doorways and adds a touch of elegance to your home. Over time, however, it can become damaged, outdated, or simply in need of an upgrade. Replacing interior door trim is a relatively straightforward project that can transform the look of your doors and add value to your home.

Materials and Tools

Before you begin, gather the necessary materials and tools:

New door trim
Mitre saw
Measuring tape
Level
Carpenter's glue
Finishing nails
Nail gun or hammer
Wood filler
Sandpaper

Removing the Old Trim

Using a pry bar or flathead screwdriver, carefully pry off the old trim. Work slowly to avoid damaging the door frame. Remove any nails or staples that may be holding the trim in place.

Measuring and Cutting the New Trim

Measure the length of the door frame on all four sides. Cut the new trim slightly longer than the measurements to allow for slight adjustments. Use a mitre saw to cut 45-degree angles at the ends of the trim pieces for the corners. Make sure the angles are mirrored for the opposite sides.

Installing the New Trim

Apply a thin layer of carpenter's glue to the back of the trim pieces. Place the trim in position and secure it with finishing nails. Use a level to ensure that the trim is installed straight. Counter-sink the nails slightly below the surface of the trim.

Filling and Finishing

Use wood filler to fill any gaps between the trim and the door frame. Allow the wood filler to dry completely. Sand the filled areas smooth and apply a fresh coat of paint or stain to match the existing trim.

Tips for Success

Measure accurately and double-check your measurements before cutting the trim.
Use a sharp mitre saw blade to ensure clean cuts.
Apply even pressure when nailing the trim to prevent splitting.
Allow the wood filler to dry completely before sanding and painting.
Consider using a brad nailer for a more professional finish.

Replacing interior door trim is a satisfying home improvement project that can enhance the aesthetics of your home. With careful planning and attention to detail, you can achieve a professional-looking result that will add value to your property.
