How to Repair Holes in Vinyl Siding

How can you repair holes in vinyl siding caused by storm damage? -Tom

Vinyl siding is both tough and durable; but like most building materials, it can sustain damage from storms and extreme weather. There are several ways to repair damaged vinyl siding, depending on the extent of the damage.

  • Repairing Small Holes: Squirt a generous dollop of exterior caulking that matches the color of the siding into the hole. Allow it to completely dry, then use a razor scraper to cut the excess caulk flush with the outside of the siding. If you can’t find caulking that matches, fill the hole with paintable caulk, then paint over it with exterior, acrylic latex paint after it has cured.
  • Repairing Larger Holes: Use a siding zip tool (available at home centers) to unlock the damaged siding at the bottom. Place foil tape on the back side of the siding to cover the hole, and lock the siding back in place. Fill the hole with a thin coat of color matched caulking, or paint the caulking to match the siding color as described above.
  • Repairing Large Holes or Cracks: Use a utility knife to cut the nailing strip off the top of a piece of matching siding that’s larger than the hole or crack, then attach it on top of the damaged piece with construction adhesive. Another option is to use the zip tool to remove the damaged piece of vinyl siding, and replace it with a new piece.

Since it may be hard to match existing siding, it’s a good idea to ask the installer for a few extra pieces and scraps to keep on hand for future repairs.

Good luck with your project,

  1. Can you post a link to the “zip” tool? I would really like to see what they look like and where to get one. Thanks.

  2. We have vinyl coated aluminum siding (installed about 25 years ago) that is peeling at the seems in certain spots on the west side of the house. The peeling exposes the bare sheeting beneath. Is there a way to fix this? The back of the house is the only area affected. Any suggestions/advice is greatly appreciated.

  3. You can also use a Mendyl patch, it is a paintable piece of pvc that covers the hole. They have a website with an instructional video also.

  4. I have window sills that are losing paint. Is this covered by my warranty?
    I had America’s Vinyl Exteriors install vinyl siding and window sills in 2006. The lifetime warranty is backed by Crane Performance Siding. Please let me know if you can help me get the window sills repaired.
