How to Repair Door Trim: A Step-by-Step Guide

Door trim can become worn, scuffed, or cracked over time. If your door trim is starting to look a little worse for wear, it can detract from the overall appearance of your home. Fortunately, repairing door trim is a simple process that most homeowners can tackle on their own. In this guide, we’ll walk you through the steps needed to repair your door trim.

Materials Needed:

  • Putty Knife
  • Sanding Block
  • Wood Filler or Spackle
  • Paint or Stain
  • Paintbrush or Foam Brush
  • Sandpaper (various grits)
  • Utility Knife
  • Wood Glue

Step 1: Remove the Damaged Trim

Use a putty knife to gently pry off any damaged trim. Be careful not to damage the surrounding area. If the trim is painted, score the paint with a utility knife to prevent chipping. Set the removed trim aside for later use as a template for the new trim.

Step 2: Sand the Surface

Use a sanding block to smooth any rough spots or bumps on the surface where the trim was removed. This creates a clean surface for the new trim to adhere to.

Step 3: Fill Any Gaps or Holes

If there are any gaps or holes in the surface, use wood filler or spackle to fill them in. Apply the filler with a putty knife, scrape off any excess, and let it dry completely. Sand the surface with sandpaper, using increasingly fine grits until it is smooth.

Step 4: Cut and Attach the New Trim

Using the old trim as a template, measure and cut the new trim to the correct length. Apply wood glue to the back of the new trim and adhere it to the surface. Use clamps to hold the trim in place until the glue dries completely.

Step 5: Sand the Trim

Use a sanding block to sand the new trim until it is flush with the surrounding surface. Sand the edges lightly to create a smooth, rounded edge.

Step 6: Finish the Trim

If you are painting the trim, use a paintbrush or foam brush to apply paint to the surface, covering both the trim and the surrounding area. If you are staining the trim, apply stain according to the manufacturer’s instructions.

Allow the paint or stain to dry completely before removing the clamps. Once the paint or stain is dry, your door trim will look as good as new!
