Repairing rotted wooden window frames and improve your home’s energy efficiency

Even high-quality wood windows can rot or develop problems over time. Here are expert ways to fix it. With repairs and regular maintenance, the life of these old wood windows can be extended.

  1. Start by checking over the whole frame to identify any areas of rot, then sand back all of the old paint.
  2. Scrape out any cracked or loose putty and replace with new putty to keep the window pane firmly in place.
  3. Remove any areas of rot or damage with a chisel, ideally removing at least a 2cm border around the damaged area and keeping the edges as neat as possible.
  4. Cut a new piece of wood to the size of the hole, being as accurate as possible.
  5. Use a mould resistant wood preservative to paint both the hole and the new piece of wood to prevent any future issues. You could also treat the rest of the frame with preservative if you feel it needs it.
  6. Glue the patch in place using an exterior grade wood glue and leave it to dry completely, ideally overnight.
  7. Use wood filler to fill in any gaps around the patch and any other small gaps or cracks in the frame. Filler can also be used to recreate any shapes or moulding on the frame which might have been damaged.
  8. Leave the filler to dry overnight and then reapply as necessary. Remember that most fillers will shrink as they dry so reapplication is usually required.
  9. Sand the areas of filler, the new patches of wood and any other rough areas of the frame to give a perfectly smooth result.
  10. Apply a coat of primer to the frame and allow to completely dry.
  11. Paint the frame in the colour of your choice. You can, of course, simply varnish the frame for a natural effect; however, the areas of filler and patches may remain visible.
