How to Patch Siding Steps
Learning how to patch siding varies based on how large the hole is. Read on to discover how to patch a small, medium, and large hole or crack in your vinyl siding.
For small holes in vinyl siding:
- Squirt exterior-grade caulk into the hole.
- Use caulk that matches the color of your siding.
- If you cannot match caulk to siding color, then buy a paintable exterior caulk.
- Leave the caulk to dry for the amount of time recommended by the manufacturer.
- Trim excess caulk away with a razor scraper so that the patch is flush with the siding.
- If you need to paint the patch, brush acrylic latex exterior paint over the caulk plug.
For medium holes in vinyl siding:
- Insert the curved end of the siding removal tool under the buttlock of the damaged piece of vinyl siding.
- Lift siding piece up gently and apply foil tape over the hole on the back of the siding.
- Snap the siding back into place.
- Apply caulk over the tape-filled hole.
- Allow caulk to dry and then scrape away excess.
- Paint if necessary.
For large holes or cracks in vinyl siding:
- Unlock the broken piece of siding with the siding removal tool.
- If desired, you can cut out just the broken siding section with a utility knife.
- Pry off the nails securing the broken piece.
- Insert a replacement piece of vinyl siding.
- Drive new nails into the nailing strip.
- Snap the buttlock of the replacement piece into the rest of the siding.
