How to Repair Vinyl Siding

While vinyl siding is incredibly durable and long-lasting, it can be damaged by debris, weather, and other incidents. Luckily, repairing it is relatively easy and if you’re a DIY-er, we can show you how to do it. All you’ll need is a few supplies and some patience. Here’s how to repair vinyl siding:

Small Piece

If you have a small piece of siding that needs replaced, you can simply apply a siding “patch” to the area to fix it.

  1. Insert a wooden shim into the bottom of the damaged piece of siding to prop it up. Then, use a zip tool to unlock the siding from the piece next to it.
  2. Repeat the previous step for the top of the siding piece.
  3. Use tin snips to make clean cuts around the damaged siding and remove it.
  4. Use a table saw or circular saw to cut a new piece of vinyl siding. Make sure this piece is slightly larger than the piece you removed.
  5. Lay a bead of caulk along the back of the patch and set the patch into place. Then, lock the siding back into place.

Large Piece

If a larger piece of siding is damaged and needs replaced, follow these steps:

  1. Insert a wooden shim into the bottom of the damaged piece of siding to prop it up. Then, use a zip tool to unlock the siding from the piece next to it.
  2. Repeat the previous step for the top of the siding piece.
  3. Use a crowbar to pry up any nails that were used to attach the piece of siding.
  4. Remove the damaged piece of siding.
  5. If your new piece of siding is larger than the piece you removed, use a table saw or circular saw to cut it to the same length.
  6. Slide the new piece into the opening and snap the top part into place.
  7. Secure the new piece with a few nails and snap the bottom into place.
