  3. Fill the Gaps: Use an epoxy wood filler to fill in any holes or cracks. Ensure the filler is applied evenly and smoothed out for a seamless finish.
  4. Sand the Surface: Once the filler has cured, sand the area to match the surrounding wood.
  5. Paint or Stain: Finish by painting or staining the repaired area to blend it with the rest of the wood.

Replacing Severely Damaged Wood

If the wood is too damaged to be repaired, it will need to be replaced. Here’s how to do it:

  1. Remove the Damaged Wood: Carefully cut out the damaged section using a saw. Be sure to wear safety gear and take precautions to avoid further damage.
  2. Cut a Replacement Piece: Measure the removed section and cut a new piece of wood to fit. It should match the type and thickness of the original wood.
  3. Install the New Piece: Secure the new piece in place using wood screws or nails. Ensure it is properly aligned with the existing structure.
  4. Seal and Protect: After installation, seal the new wood with a protective finish to prevent future infestations.
