If you have wooden window frames or sills, it’s important to keep them in good condition. Over time, sun, wind, and rain can cause damage to the wood, making it less efficient and potentially increasing your heating bills. If you notice any damage, it’s best to address it as soon as possible. While replacing your windows is the best option, if that’s not possible, you can fix small holes and damage with a few DIY tips.

To start, assess the extent of the damage by using a screwdriver, knife, or ice pick to probe the affected sections. If the wood resists puncture, you can repair it with epoxy filler.

Here are the steps to follow:

  1. Use a knife or wood chisel to remove any loose or damaged wood, making sure to only leave firm and dry wood.
  2. Scrape off any paint, grease, or oil on and around the affected area using a paint scraper or sandpaper.
  3. You can also drill holes into the surrounding damaged wood to allow the epoxy to penetrate deeper into it. But be sure not to drill all the way through the wood.
  4. Apply a bonding agent or liquid wood to the wood so the epoxy will adhere better to it.
  5. Use painter’s tape to secure off the surrounding areas that you will not be working on.
  6. Fill all cleaned areas of the window frame with the epoxy filler. Use a putty knife to smooth it off to match the shape of the affected area. Don’t worry too much about being too meticulous as you can sand it off later.
  7. Leave it to dry overnight or for about 24 hours.
  8. Sand the filled area with sandpaper or an electric sander until it is smooth.
  9. Apply one coat of primer and two coats of the matching paint or wood stain.

Epoxy is a great material for repairing wooden window frames

Epoxy is a great material for repairing wooden window frames as it flexes with the wood as it expands and contracts. Epoxy can also be painted, stained, carved, nailed, and drilled just like wood. Repairing damaged wood windows early on is important as they are less efficient and could be increasing your heating bills. By catching damaged wood early, it’s easier to perform DIY repairs that are both durable and permanent.

For small holes in a wooden window frame, wood filler or putty can be used. Simply apply the material to the hole, smooth it with a putty knife, and allow it to dry before sanding. Additional applications may be required as the material shrinks during drying. Fine-grit sandpaper can be used to create a smooth surface on the repair. Alternatively, all-purpose auto body filler is perfect for repairing holes in wooden surfaces. The two-part filler is activated by applying a hardener and dries within minutes, allowing you to finish the repair faster. Since the material does not shrink, one application is usually all that is required.

If the tool penetrates through the surface, you may want to consider replacing that portion of the window with new wood or replacing the entire window completely. Remember that regular maintenance and upkeep of your wooden windows can help extend their lifespan and keep your home looking its best.
