Vinyl, or PVC, fences are durable and low maintenance but like anything, they can get damaged over time. You can easily and affordably repair small cracks and holes or replace broken rails, panels, or posts. But if you are an inexperienced DIYer, then you’ll need to know how to repair a vinyl fence.
Fencing provides homeowners with security and protection. So whether you have a vinyl picket or privacy fence, it’s important to keep it properly maintained.
Common vinyl fence repairs
Damage to vinyl fencing happens thanks to weather, pets, people, and other physical forces. Inspect for damage when performing regular fence maintenance. When fence damage occurs, it’s important to fix the issues right away to avoid having to replace the entire fence.
- Patching cracks and holes: Constant exposure to sunlight leads to small cracks and holes that could compromise the entire panel.
- Repairing a vinyl fence section: Repairing a vinyl fence is a simple process since each section of the fence is put together separately, and you can replace individual pieces without taking apart the entire fence.
- Replacing panels: Replacing an entire vinyl fence panel may be necessary if there are too many large holes and cracks.
- Replacing a broken fence post: Replacing broken posts involves completely removing the concrete foundation in order to fix the new post with fresh concrete.
- Installing new vinyl fence rails: Vinyl fence rails hold the slats or pickets in place. Damaged rails can’t be repaired, but they are easy to replace.
How to patch cracks and holes
Holes and cracks are pretty common in vinyl fencing, but they are relatively easy and inexpensive to repair.
Materials needed
- Water with a gentle cleanser like dish soap
- Soft rag
- Medium 80-grit sandpaper
- Fine 180 grit sandpaper
- Expandable foam in a spray can
- Fine-tooth saw
- Putty knife
- Plastic filler
- Spray paint
Step 1: Clean the damaged area
Wash away any dirt or grime around the damaged area with soapy water and a soft sponge or rag, then rinse with a garden hose. Let the area completely dry before you continue with the repair.
Step 2: Sand the damaged area
Use medium 80-grit sandpaper to sand the damaged area. Do not use a sander because it causes more damage. Wipe the area clean with a damp cloth.
Step 3: Fill with spray foam
Push the nozzle of the expandable foam spray deep into each crevice and fill all cracks and holes. Fill slowly and let the foam expand past the top of the hole. Let the foam dry overnight.
Step 4: Cut and sand the excess foam
Wait for about 8-12 hours for the foam to completely dry. Cut away any foam that has expanded past the top of the hole with a fine-tooth saw and then level the surface with medium-grit sandpaper. Wipe the area clean with a damp cloth and then let it dry.
Step 5: Smooth the surface
Seal the foam by applying plastic filler to the area with a putty knife. Use the putty knife to smooth it flush with the vinyl fence. You can also fill small cracks with plastic filler. Wait for the plastic to dry.
Step 6: Sand out any filler excess
Remove any excess plastic filler with fine-grit sandpaper until the surface is perfectly flush. Wipe with a damp cloth and let the area dry.
Step 7: Paint to match with epoxy paint
Apply a coat of plastic or vinyl epoxy paint in a color that matches your vinyl fence. Once the paint is dry, your repair is complete!
How to repair a vinyl fence section
You might be concerned when you see an entire section of fence damaged, but the repair is quite quick and straightforward.
Materials needed
- Chisel

Step 3: Remove the top rail
You can remove the top rail by sliding it over and lifting it from the post.

Step 5: Repair the damage.
Determine what caused the section to be damaged and repair it accordingly, using any of the repair methods mentioned, depending on if you need to patch cracks and holes, or repair posts, panels, or rails.
Step 6: Put the fence back together
Replace the slats in the reverse order that they were removed, starting from the bottom. Place the top rail and the caps back in place as well.

Materials needed
- Electric screwdriver
- Level
- Vinyl fence panel
- Screws
Step 1: Buy a matching/compatible panel
Buy a new panel that matches the rest of your vinyl fence. Some manufacturers sell replacement panels, but if they don’t, you will have to find something that is at least compatible with your fence model.
Step 2: Remove the broken panel
Remove the broken panel. If your fence panels are fastened with screws, use an electric screwdriver to remove the panel.
Step 3: Use a level to check the alignment
Check the alignment of each connecting fence posts from top to bottom with a level. Straighten the posts as needed.

How to replace a broken fence post
Replacing a fence post requires some patience but is fairly inexpensive.
Materials needed
- Electric screwdriver
- Shovel and spade
- Measuring tape
- Concrete (120 lbs. premixed)
- Compatible vinyl fence post
- Sledgehammer
- Digging bar
Step 1: Remove the rails and panels
Remove the rails and panels from both sides of the broken post. Use an electric screwdriver to remove the fasteners if the type of fence you have is secured with screws.
Step 2: Dig out the old post and concrete
Using a shovel, dig out the old post. If your posts are set with concrete, remove the old concrete foundation, either with the shovel, or by breaking up the concrete with a sledgehammer and digging bar.
Step 3: Measure the distance between the posts
To determine where the new post should go, measure the distance between two existing posts with measuring tape. If your fence was installed incorrectly, cover the old post’s hole and dig a new hole for the new post. The hole should be 3 feet deep and have a diameter of 8 inches.
Step 4: Place the new post
Place the new pole in the center of the hole and seal with 120 lbs. of premixed concrete. Let the concrete set and dry overnight.
Step 5: Reinstall the fence panels and rails
Attach the fence panels and rails to the new post to complete your repair.

Slide the new rail in place; if you can’t find a compatible replacement, buy a longer rail and cut it to the right dimension with a circular saw. Fasten the new rail in place with screws or brackets, depending on the type of fence you have to complete the repair.
