How To Repair Vinyl Siding?

Cracked or damaged vinyl siding looks ugly. It is quickly spotted by everyone, no matter how emphatically you try to convince yourself that no one else has noticed it. 

The general misconception about repairing vinyl siding is that it can cost an arm and a leg to mend a tiny hole. But, the process doesn’t need to be that expensive, right?

The trick is to take a DIY route that can save you up to thousands of dollars. 

Repairing vinyl siding on your own is a skill every DIYer must learn. The good thing is, knowing the right tools and the basic procedure will help you fix any vinyl siding damage in no time. 

How to Identify that Your Vinyl Siding Needs a Repair or a Replacement?

While cracks and holes are a clear indication that your vinyl siding needs repair, it is not the only sign. 

Many times, a siding that looks perfectly fine needs repair because the signs of damage are not visible to the naked eye. 

Here it’s important to understand that vinyl siding isn’t only responsible for enhancing your home aesthetics but also prevents moisture and pests. This is one of the biggest reasons you have to ensure it’s in excellent shape. 

Here are some signs that the siding in your home calls for repair or replacement:

  • Cracks/chips/holes: This is the most obvious sign of vinyl siding damage. Any dent, crack, or hole can be an invitation for insects and fungus underneath
  • Discoloration: If your siding isn’t able to maintain its color, it’s an indication that its waterproof capacity is subsiding, which could result in further damage if not treated in time
  • Warped panels: Warped or bubbling panels are an outcome of harsh weather conditions. Warping gives rise to holes and gaps that further expose your home to other external elements
  • Mold or fungus: If you observe any mold or fungus on or underneath the siding, you must locate the origin of leakage and fix it as soon as possible
  • Rot underneath: Even if your vinyl siding looks fine from the top, but the wood underneath is rotten, you may need to repair or replace it for the best results
  • Loose siding: Dents and gaps resulting from loose or cracked siding can allow moisture and rainwater to enter between the panels and ruin interiors

Once you spot the exact location of damage, you must look for the right tools to start repair.

Tools Required

  • Hammer
  • Utility knife
  • Pry bar
  • Zip tool
  • Caulking gun
  • Tin snips
  • Tape measure

You may also need to have a replacement panel in case you’re following the patching/replacement method.

If you’re replacing your old vinyl siding, simply take the broken piece to siding distributors in your area to find the best possible match. Even if you can’t find the exact match, take the sample to a paint shop and have the exact colors matched. 

How Do You Repair Vinyl Siding?

There is no denying the fact that vinyl siding is built to last. But similar to any other thing, it can sustain damage with time. 

This comprehensive vinyl siding repair guide will help you mend and replace any vinyl siding without much difficulty. 

Preparation

Whether your vinyl siding is damaged due to harsh weather conditions or some manual mishap, there are many ways you can fix your siding. 

If the damage isn’t extensive, all you need to do is to fill holes with matching caulk, and you’re good to go. 

Clean the Area

The next step would be to clean the affected area. You can do that with the help of a sponge and some soap water. Give adequate time for drying before you move to the next step.

Get Your Caulk Gun Ready

To prepare your caulk gun simply cut the tip off and puncture the seal using any sharp object. Pull the plunger and load up the caulk tube. 

Fill the Holes

Put in the tube’s nozzle in the siding hole and start filling it with caulk. Make sure you overfill the dent to ensure there is no space left. Let the caulk dry for at least 24-hours. Get rid of excess caulk using a scraper. 

How to Repair Vinyl Siding Using a Patch?

If the hole inside your siding is too big to be covered with caulk, you can use a patch to solve this issue. While this process is a little time-consuming, it guarantees the best and reliable results. 

For this, the first step would be the same. Simply clean the area with a sponge and soap water. Let it dry for at least 2 -hours before you start patching the holes. 

Cut Out a Patch

Cut out a patch from a scrap piece of siding. Make sure you cut a bigger piece than the hole. Place the patch over the affected area to test if it perfectly fits the siding curves. Trim down the excess siding until the patch properly fits over the hole. 

Patch it

Apply caulk on the backside of the patch. Also, apply a small quantity around the hole. Place and press the patch over the damaged area and let it dry. Once completely dry, scrape off the excess chalk from the edges. 

Don’t forget to fill in additional gaps or holes present on the side panels. This provides complete protection against moisture and insects. 

How to Replace Vinyl Siding?

If the siding damage is beyond repair, you may need to consider replacing your siding. For this, all you need to do is follow a 15-minutes DIY repair process that is absolutely simple and affordable. 

Step 1 – Separate the Two Connected Panels

Place the hook under the panel with the help of a zip tool. Slide the tool in a horizontal direction to separate the two connected panels while keeping the handle lifted. 

Step 2 – Get Rid of the Fasteners

Use a pry bar or a hammer to get rid of fasteners, nails, and screws that fix the panel to the sheathing. Lift the bottom corner of the upper panel and remove the fasteners.  

Step 3 – Prepare a New Panel

Cut a new vinyl siding panel using a utility knife. Make sure you properly measure the length and width of the damaged area. Lift the new panel on top of the bottom edge to ensure it perfectly fixes over the lower piece. Your goal is to fit the top of the panel underneath the vinyl siding above it. 

Step 4 – Fix the New Panel

Once you’ve successfully removed the damaged part and also prepared a new sliding, it’s time to fix it by lifting the bottom edge of the upper panel. 

Use nails and screws to fasten the fresh panel. However, you must leave enough space to allow expansion and contraction. Help hold the panel using a tape measure as you fix it. 

Step 5 – Lock Both Panels Together

The last step is to secure the panels together using the zip tool. Slide the tool in the tab direction and apply pressure against the new panel. This will ensure both panels are perfectly connected with each other. 

And, this is it. Simple, isn’t it?

Step back and take a moment to admire all the hard work you’ve done to make this vinyl siding project successful.  

While vinyl siding is tough and doesn’t need routine maintenance, there are still some steps you can follow to keep your siding in good shape. 

Keep your siding clean using a soft bristle brush to remove dirt and dust. Always shield the exposed area of your siding with cover, especially when you’re having a home renovation project in progress. 

Keep an eye on your siding to observe any holes and cracks so that you can fill them up with caulk or a patch in time to prevent further damage.
