How to Fix Holes in Vinyl Siding

Vinyl siding is extremely durable with an expected lifespan of 40+ years. Unlike how it is with wood siding, you wouldn’t have to worry about deterioration in quality due to natural elements. Vinyl siding requires very little maintenance like some necessary washing. 

However, there are some issues which can reduce the lifespan of your vinyl siding, one of which is hole formation. So fix cracks and holes in the siding immediately as they will only lead to extensive damage if left unattended. 

Similar to wood siding repairs, there a few methods to repair holes in your vinyl siding. The repair method you follow depends on the size and type of damage you’re dealing with.

As discussed before, failing to fix large holes in your siding at the earliest could result in serious damage to your house. 

The first step in repairing them is to clean the siding and the work area of any dust and debris as they can prevent the patch from adhereing properly to the siding. 

  1. First, buy a vinyl siding patch kit which matches the colour and texture of your house’s existing siding. 
  2. Cut out a patch piece slightly larger than hole in your siding. 
  3. Then, apply adhesive to the back of the patch piece you just cut. 
  4. Insert the patch piece over the hole and trim away the excess material. 
  5. Attach the piece firmly over the hole to ensure proper adhesion. 
  6. If needed, you can use screws and nails to attach the patch for extra reinforcement. 
  7. Sand down and wipe the replacement patch for a smooth finish. 
  8. Finally, paint or stain the area for it to match the existing siding. 

Steps to Repair Medium Holes in Vinyl Siding

For medium sized holes in your siding, use replacement vinyl siding. Replacement siding refers to individual siding pieces or panels used to replace damaged existing siding. 

  1. First, clean the vinyl siding and work area with mild detergent and water and let it dry. 
  2. Cut a piece of replacement siding; this piece should be slightly bigger than the hole. 
  3. Apply exterior-grade adhesive to the back of the replacement siding panel. 
  4. Attach the replacement panel securely onto the damaged area, making sure it aligns with the existing siding panels. 
  5. For extra reinforcement, you can use screws and nails along the edges to secure the panel. 
  6. Cut away any excess siding material after the adhesive has completely dried. 
  7. Sand the area and clean it to remove any remaining adhesive. 
  8. Paint over the replacement siding panel for it to match the existing siding. 

Steps to Repair Small Holes in Vinyl Siding

  1. Clean the area around the siding hole with water and mild detergent and wait for it to dry completely. 
  2. Apply a small amount of exterior-grade caulk into the hole and fill it up. 
  3. Then, use your finger or a small putty knife to smooth out the caulk. 
  4. If required, use a vinyl siding patch kit to cover the hole and secure it neatly with adhesive or screws. 
  5. Remove excess caulk with a scraper or a utility knife and clean the area thoroughly to ensure a smooth finish. 
  6. Paint or stain the area with a colour that matches the existing siding.

Wood siding is durable and will last you 20-40 years if maintained well. To make your wood siding last longer, scrape, sand and paint it every 5 years.

  2. Place the hole saw over the hole in the siding and carefully drill a hole over the damaged spot. While drilling into the siding, be very careful to not damage the tar paper or house wrap underneath. 
  3. If there is a gap between the siding and the house wrap, fill it using spray foam sealant and cut away the excess after it cures. 
  4. Use a hole saw to trace a circle onto a piece of replacement siding material. 
  5. Then, use a jigsaw or a slightly larger hole saw to cut out the shape. 
  6. Test the replacement piece to make sure it fits over the siding hole. 
  7. Spread wood filler around the the circumference of the circle and the inside of the hole and attach the new piece to the hole tightly, letting the excess filler to squeeze out through the edges. 
  8. Next, apply a thin layer of wood filler to the patch and its edges to fill any remaining gaps or voids. 
  9. After the filler has cured, scrape and sand to match the existing siding’s texture.
  10. Finally, paint and add finishing touches to achieve the desired look.

  2. You can fix small holes which don’t extend all the way through by using epoxy putty which you can use to match the existing siding or paint over later to match the rest of the house. 
  3. If the hole extends deep through the siding to create a gap between the house’s tar paper or protective wrap, apply a small amount of spray foam sealant in the hole to provide a base for the compound. 
  4. If the foam reaches past the face of the siding while curing, cut away the excess to create a void for the epoxy to fill. 
  5. After the epoxy putty has cured, sand it to match the existing siding. 
  6. Finally, paint or stain the area to achieve the desired look.
