How to Repair Vinyl Siding


Vinyl siding is known for being affordable and attractive, which makes it one of the most popular types of siding among homeowners. It’s available in an assortment of colors, and it makes customizing your home exactly how you want it a cinch.

Unfortunately, siding won’t last forever without taking at least a few bumps and bruises along the way. The good news, though, is that vinyl siding is simple to repair, and as long as it’s only damaged in a few locations, you can restore it back to like-new condition with minimal effort and only a slight expense. In nearly every instance where siding is damaged, it makes most sense to completely replace the piece, since only completely intact pieces provide the durable weather resistance that vinyl is known for.

Locate the Breakage

The very first step to repairing vinyl siding is to locate the damaged spot. If you’re considering making a repair, you’ve probably completed this step, but in favor of being thorough, you should walk around your home and briefly look for additional damaged locations. If you’re going to be replacing one section of siding already, it makes sense to fix all the damaged spots at once. Locate each damaged location and make note so that you know where each is.

Acquire New Siding

If you don’t have additional siding panels at home to cover the repairs that you need to make, it’s time for a trip to the local home improvement store. Look around the store for siding that matches your current color. Match it as closely as you can, realizing that the new siding will be brighter than the old siding is because it hasn’t yet faded in the sun.

It’s beneficial to buy extra siding when you have your house sided, or at the very least to keep track of your supplier. If you didn’t do this, and you have to track down additional siding to make the repair, it’s helpful to bring a piece of the siding with you when matching to a new piece.

Pull Off Donor Siding From Your Home

If the damaged siding is in a highly visible location, you don’t want to replace it with brand-new siding. If you do, the contrast will stand out, rather than blending in as it should. Instead, you should cut off a section of faded siding from a less visible part of your home that’s large enough to repair the damaged area of your house. With that section removed from the less visible part of your home, you can install the new siding in its place where it won’t be noticed, and then take the faded siding over to the damaged location.

Cut Off the Damaged Siding

Cut off the damaged siding using a carpenter’s square and a utility knife to make the face cut, and use a pair of snips to cut the top and bottom lip of the siding.  Be careful to cut away siding about four inches shorter than the patch piece—this is so the faded patch of siding you put in has a two-inch overhang at either side of the installation point.

Remove it

Run a siding removal tool along the bottom of the next row of siding above to unlock the bottom lip from where it latches to the broken piece below. Lift that siding up and away and pry out the nails holding the broken siding in place.

Install the Siding

Cut off the top and bottom channels at either end of the siding for about two inches. This is so the faded siding you put on can sit above the surrounding siding without the need to unhook additional nails. Lock the bottom of the siding into the full row of siding below it and slide it into position so that two inches overhang either side of the patched area. Hammer siding nails in the center of the open slots at the top of the siding, taking care not to lock the panels down tight against the house. Leave a small gap to allow the siding to slide a bit when it expands and contracts. Nail all along the repair location and then lock the bottom lip of the next row up into the top of the patched siding and you’re finished with the repair.


This procedure works for any holes or cuts that appear in siding around your home. If most of the siding is in pretty good condition, it makes sense to patch the area rather than replacing all the siding. Take care to keep up on these regular repairs and you won’t have to worry about weather damage to your house.
