Step 1: Unlock the Siding

Use a zip tool (Image 1) to unlock the siding from the surrounding pieces (Image 2). Start at the bottom of the piece that is being replaced, and insert a wooden shim between the pieces of siding as the zip tool slides along the siding. Repeat the procedure for the top of the damaged siding.

Step 2: Patch the Damaged Area

Use tin snips to cut out the damaged area (Image 1). Use a table saw or circular saw to cut a patch from a good piece of vinyl. The patch should be larger than the piece you removed.

Run a bead of adhesive caulk around the back of the patch, and set the patch in place (top image). Then lock the siding back into place.
