How To Repair Holes In Vinyl Siding

by Connor Pena

Vinyl siding is a durable siding material for your home. It's easy to install, fairly cheap and comes in a wide range of colors and styles. Vinyl siding is also resistant to weather and insect rot. It doesn't take a lot of maintenance, however, it is not completely maintenance free. Vinyl siding needs to be cleaned to prevent mildew from building up, and over time it can become brittle, making it susceptible to holes and cracks. If not repaired, those holes and cracks can become an easy place for insects to make their homes in, or even water damage. See below for instructions on how to repair those holes/cracks.

Here's What You'll Need:

  • Caulk color (to match your siding) and caulk gun
  • Vinyl siding (to match your existing siding)
  • Scraper
  • Utility knife
  • Sponge
  • Dish detergent 
  • Warm water
  • Bucket

Instructions (for small puncture holes):

  1. Mix the dish detergent and warm water together in a bucket. Grab a sponge and begin gently cleaning the area around the hole in your siding. Rinse the mixture from your siding and allow it to dry completely.
  2. Next, take your caulk gun and begin filling the hole with the caulking. Over-fill the hole so there is caulking on the exterior of the hole/siding.
  3. Using your scraper, scrape off the excess caulk from the exterior of the hole/siding. Do this gently, so you don't remove the caulk from the hole itself.
  4. Allow the caulk to dry, then use your utility knife to get rid of the caulking on the siding. The caulk inside the hole should help keep bugs and water from damaging your home.

 Instructions (for larger holes):

  1. Clean the siding as instructed above using the mild dish detergent and warm water mixture. Allow the siding to dry before proceeding.
  2. Next, cut a piece of vinyl siding to match your siding that is slightly larger than the hole or crack.To cut the siding, simply score it with your utility knife and then snap it off.
  3. Cut the nail holes off of the siding, but keep the upper lip and lower edges.
  4. Then, place the patch of siding over the hole/crack to be sure it fits properly. If you need to, you can cut off the lower edge.
  5. Using the color-matching caulk, apply caulking to the back of the patch and to the area around the hole/crack.
  6. Press and hold the patch in place to ensure it sticks properly, then allow it to dry completely. Scrape off any excess caulking around the patch itself once it's dry using the utility knife.

Repairing holes in vinyl siding helps to prevent water and insect damage from occurring. If your siding is damaged beyond repair, it may be time to invest in new siding. Call out a professional siding installer for an estimate. You can also visit websites like for more information.
