How to Replace One Piece of Vinyl Siding

Vinyl siding resists cracking, peeling and chipping, but after years of installation it may require repairs or replacement.

Houses can be covered entirely with vinyl siding or partial siding and stone or brickHouses can be covered entirely with vinyl siding or partial siding and stone or brick
Replacing small portions of vinyl siding can repair damages due to wind, falling trees and limbs or brittleness in extremely low temperatures. Using the correct procedures in replacing one piece of vinyl siding, you can blend it in with the entire wall of the house so that the repair is not noticeable.

Use a zip tool to pry the edge of the damaged vinyl siding out from its chamber on one end. A zip tool has a rubber handle and bends in a 45-degree angle forward with a small slot on the end. It fits the channels of vinyl siding for easy removal and replacement. Slide the zip tool under the edge of the siding and slide the entire length to release it. Pull the piece out with a pry bar and use a nail puller to pull all of the nails away. Pull the siding upwards and out to remove.

Measure the area where the vinyl siding was removed with a measuring tape and add 2 inches to the measurement. Measure the new piece of vinyl siding and mark with chalk. Cut the vinyl siding on chalk lines with tin snips to the correct size.

Place the new siding on top of the replacement area with a 1-inch overhang on each end above the original siding. Lock the bottom of the new siding piece into the top of the piece below by inserting it into the slot and pushing down all across the length of the new piece. Slide the zip tool underneath the new siding and slide it down its length to secure the new siding in its chamber.

Hammer galvanized nails into the nail slots at the top of the replacement vinyl siding. Secure the top of the siding by inserting the zip tool at one end and sliding across the entire top length of the replacement siding.

Tips

  • If you do not have additional vinyl siding for repairs from your original installation, remove the old portion and take to a merchant to match the style, size and color. This will produce a professional repair job that is not apparent so that it blends in with the wall.
  • Do not nail the nails into the wall completely tight. Siding needs some room for expansion due to changing weather conditions.
  • Replace lengths of vinyl siding that span at least three studs so that they fasten with nails on each end and in the middle. This provides better support for your repairs than replacing a small portion.
  • A large flat screwdriver can replace the zip tool in installation and repairs of vinyl siding, though the zip tool works best due to its shape and size.
