How to Repair Holes in Vinyl Siding

By Amanda Lutz Updated May 13, 2024

Due to its durability, affordability, and aesthetic appeal, vinyl siding is a popular choice for protecting modern home exteriors. Vinyl is a dependable siding material that lasts up to 50 years and can protect your home from elements such as rain, snow, and winds of 110 mph. But, it can also sustain damage throughout its life span. 

Impact damage, severe storms, and changes to your home’s exterior can leave unsightly holes in your vinyl siding that detract from your home’s curb appeal and expose your home’s structure to moisture. Whether looking at small holes caused by an exterior home renovation or a baseball-sized hole after a particularly vigorous play session, you may be wondering if this is a home repair you can take on yourself. Luckily, repairing holes in vinyl siding is often a reasonably simple do-it-yourself (DIY) project. Our guide will share everything you need to know about repairing vinyl siding, including safety considerations, the tools you need, how to patch holes of various sizes, and when to contact a professional.

Safety Considerations

Before beginning any DIY home improvement project, learning how to complete the job safely is essential. All too often, the areas of vinyl siding that require repair aren’t close to ground level, and large holes will require using potentially dangerous tools. When using a ladder, place it firmly on stable ground and ensure that it’s tall enough for you to reach the damage comfortably. Unless you’re repairing a very small hole, you’ll use tools—such as a circular saw or tin snips—to cut patches or damaged pieces for a smooth finish. Always wear safety goggles and gloves when cutting any material with a sharp tool.

Tools Needed to Repair Vinyl Siding

You’ll need several tools and materials to properly repair holes in your home’s vinyl siding. Depending on the damage’s size and extent, you may need to remove materials and use patches along with adhesive materials. Before your repair job, ensure you have these tools and materials on hand.

Repairing Small Holes in Vinyl Siding

Small holes and dents are the most common damage to vinyl siding. This damage can come from hail, small rocks thrown by a lawn mower, or nail holes from removed exterior trim. Luckily, it’s easy to repair these holes without replacing an entire siding panel. 

Follow these simple steps to repair small holes in vinyl siding: 

1. Clean Damaged Areas

Any type of caulk or adhesive needs a clean surface for optimal adhesion. To prep the damaged area, use a soft sponge or cloth to clean the area with soap and water. Rinse any remaining soap and ensure the spot is completely dry before beginning your repair.

2. Apply Caulk Over the Hole

When choosing the caulk you’ll use for repairs, select a color as close to that of your siding as possible. Paintable caulk is also available to allow you to paint your siding. Load a caulking gun with waterproof caulk. Squeeze a small bead of caulk into dents and holes, ensuring holes are completely filled. After applying caulk, use a plastic putty knife to wipe away excess caulk.

3. Let the Caulk Dry

Caulk can take a long time to dry. Follow the manufacturer’s instructions exactly when calculating accurate drying time. A full day isn’t unusual; attempting to finish the caulk before it’s completely dry can damage your repair. 

4. Trim Caulk and Add Finishing Touches

The final touches make your caulk flush with your siding, so it’s practically invisible. If the dried caulk has uneven patches, trim it with your utility knife so it’s flush with the siding. If you’re using a paintable caulk, finish the repair with exterior paint that matches your siding.

Repairing Medium Holes in Vinyl Siding

Any hole that’s larger than an inch is a medium-sized hole. These damaged areas are typically caused by mishaps such as impact from small objects, corrosion from metal elements that come into contact with your siding, or poor installation. When dealing with holes that require patching, it’s best to complete the project during warmer months because freezing temperatures make siding brittle and easy to break.

Follow these step-by-step instructions to repair medium-sized holes in vinyl siding:

1. Unlock Damaged Siding

Use your zip tool to unlock the damaged piece of siding by pulling it down and out to unlock the bottom lip. Slide the tool along the edge, carefully pulling the siding out as you move along. Use your pry bar to remove the nails holding the top of the siding in place.

2. Apply Foil Tape, and Lock the Siding Back in Place

Larger holes require backing to give the caulk something to adhere to. Apply foil tape to the back of the siding over the hole. Lock the siding piece back in place to complete the repair.

3. Spread Caulk Over the Hole

You can apply caulk to fill the hole using the foil tape for support. Load your caulking gun with a waterproof caulk matching your home’s siding shade. Squeeze enough caulk to cover the exposed foil tape and slightly overfill the hole. Use your putty knife to wipe away excess materials.

4. Allow the Caulk to Dry and Apply Finishing Touches

Leave the caulk to dry per the manufacturer’s instructions. Once dry, smooth away any uneven patches by trimming dried caulk with a utility knife and sanding the area smooth. If your caulk isn’t an exact siding match, paint over the repair with matching exterior paint.

Repairing Large Holes in Vinyl Siding

Large holes in siding typically require more extensive repairs. Major damage can occur for a variety of reasons. Storm-driven branches and twigs are a common cause of siding damage. Pests or animals can also cause substantial damage from scratching, chewing, or other nesting activities. You’ll need to patch any large holes in your vinyl siding, or you may need to replace the panel altogether.

Follow these steps to repair large holes in vinyl siding:

1. Purchase Replacement Siding

Large holes will need matching siding for repairs. Homeowners often have extra siding left over from installation. If you don’t have some on hand, you can purchase siding that’s a close match at your local home improvement store.

When you compare new siding (or even siding in storage) to your home’s existing siding, you may notice the new siding is noticeably darker because vinyl exposed to sunlight tends to fade. If you’re repairing the front of your home, you may want to remove a piece of vinyl siding from an inconspicuous area for patching. Use the new piece in a less noticeable spot.

2. Cut Out Damaged Siding

For this size of repair, you’ll want to replace a section of the siding. Use your utility knife to carefully cut out the damaged section without damaging the paper underneath. Unlock the bottom lip of the siding piece with your zip tool and slide the tool along the edge of the damaged piece to loosen it completely. You can typically leave the nailed top portion in place. Remove the nails with a pry bar if the top portion is damaged.

3. Prepare a Patch

Use your tape measure to measure the damaged area. Measure and cut a piece of replacement siding a couple of inches longer on each side than the damaged piece. Trim off the nailing strip if you don’t plan to use it. Align the patch in its intended spot to ensure it’s a good match.

4. Install Your Patch

Apply construction adhesive to the back edges of the patch and carefully slide it into place until the bottom lip locks. If you’re using the nailing strip, hammer the nails into place. Press the patch firmly into place to ensure good adhesion. If nailing isn’t required, consider using duct tape to keep your patch in place until the adhesive dries. Wipe away any excess adhesive before allowing it to dry.

5. Complete the Finishing Touches

If any excess adhesive remains after drying, trim it away with your utility knife. If the patch doesn’t match as closely as you’d like, paint it with exterior paint that matches your siding.

When to Call a Professional

While you can complete many vinyl siding repairs yourself, some types of damage warrant professional repair. If you’re concerned the repair is beyond your physical capabilities, it’s always best to call a pro. For example, if you need to repair extensive siding damage far off the ground, you should have substantial experience working from a ladder.

Before attempting to repair your siding, it’s essential to consider whether there’s damage underneath. If you have a medium or large hole in your siding, check the wood underneath for signs of moisture or mildew. If you think the damage goes deeper than your siding, call a professional for a thorough inspection. Any major siding repair is likely to require the services of a professional if you haven’t previously worked with siding.

Our Recommendation

Patching vinyl siding is an important part of home maintenance that you can often complete on your own with the right tools. The hole size in your siding will influence the steps you need to take to complete the repair properly. Typically, You can repair small holes quickly with waterproof caulk, but larger holes require a patch. If you’re uncomfortable doing your own repairs, or suspect the wood underneath has sustained water damage, contact a professional for assistance.
