Small holes can be easily repaired with a vinyl siding repair kit.
Matching the color of new siding with existing siding may be challenging but not impossible.
Repairing large holes may require professional assistance.
Proper safety precautions and tools must be used to avoid further damage.

Assess The Damage

Before you start to repair the hole, it’s important to assess the damage so you can plan your project.

Check the size of the hole. If it’s small, you may be able to patch it up with caulk alone. However, if it has broken through more than one layer of siding and there is exposed insulation or wiring showing, you’ll need a more thorough repair job.

Check where on your house this hole is located and whether or not there are any other areas nearby that could be damaged by water seeping into them through bad siding seals or loose nails holding down sections of siding board that were damaged by water penetration this includes windows and doors as well as any parts of your home where water may enter from above ground level due to rain runoff issues (lawn sprinkler systems).

Check if there are any exposed wires hanging around near where you found these holes in your wall; if so then don’t touch them!

If you have plumbing issues at home, it’s better to fix them as soon as possible to avoid bigger problems. Follow our pro-guide on how to fix plumbing issues to learn about common plumbing problems, their causes, and how to fix them yourself.

Examine The Extent Of The Damage

Once you have done your initial inspection and determined the extent of the damage, you can decide on a plan of action. 

If it appears that only the surface of the siding has been compromised and there is little risk to other parts of the wall, you may be able to repair it yourself with a quick patch job.

If there are areas where water or insects have penetrated deeper into your home’s structure, then you should consult with a professional for advice as to what type of repair will work best for your particular situation.

Table: Examine the Extent of the Damage

MinorDamage is limited to a small area and can be easily repaired with a simple patch
ModerateDamage is more extensive and may require partial replacement of the siding
MajorDamage is severe, affecting a large area of the siding, and may require full replacement of the affected area
UnknownDamage is not clear and requires further inspection to determine the severity

This table suggests the severity of the damage based on the extent of the damage inspection. It categorizes the damage based on the level of severity which can help to decide the appropriate plan of action.

Remove Loose Material

Use a paint scraper to remove loose material, but be careful not to gouge the surface below. Keep scraping until you have removed all of the loose material and only intact siding remains between holes in your house’s exterior. 

You may need to use a wire brush or hammer for this step if the scraper does not work well enough on its own.

Install Backer Board (If Needed)

If your siding has been damaged, you may want to use backer board to ensure that moisture doesn’t seep through the hole. 

Backer board is a thin layer of foam insulation that is used to prevent moisture from seeping through the siding. It can be purchased at a home improvement store and can be installed before or after the patching compound is applied.

Cut A Patch

You can use a utility knife and straightedge to cut the patch. If you have an electric jigsaw, you can use that instead of a utility knife. Just make sure to keep the blade at 90 degrees to the surface of your siding when cutting out the shape of your patch. 

Once you’ve finished cutting out your patch, place it against your damaged siding, then trace around its edges with a pencil. This will help prevent any mistakes when you’re cutting out your new piece for installation later on in this process.

Once all four sides are traced onto your replacement piece (and two pieces if necessary), remove them from their backing and carefully apply them over top of where they will be installed on either side of each hole or crack in question

Mix The Patching Compound

To mix the patching compound, you can use a cement mixer. Mix it with water according to the instructions on its packaging. Let it dry for at least 24 hours before painting over it.

This table suggests the materials needed and the steps involved in mixing the patching compound. It can be used as a quick reference when repairing holes in vinyl siding.

Apply The Patch And Hold In Place

Once you have applied the patch, hold it in place for at least 24 hours until it dries. If you are using a patching compound, you will need to hold the patch in place for at least 24 hours before painting or taping over it.

Outside siding tends to deteriorate with time and exposure to the environment. If you notice any cracks, dents, or holes in your outside siding, check out our guide on how to repair outside siding for step-by-step instructions on how to repair it yourself without the need for external help.

Smooth Out And Allow To Dry

The last step is to smooth out the patch. You can do this by using a putty knife or trowel, but don’t press too hard. 

Layering on too much pressure will cause the material to crack. This will ruin your repair and make you wish you had never started.

Let it dry for 24 hours before touching it again! If you’re impatient like me, use blue masking tape around the perimeter of your patch and peel away once it’s set. 

I find that if I don’t wash off excess plaster with a water hose, it ends up looking cloudy due to small air bubbles trapped inside (they basically boil when they dry).

Apply Primer And Paint (If Needed)

The final step is applying primer and paint to the repair. Primer helps to prevent paint from peeling off, while also hiding any imperfections in the surface. 

Paint keeps moisture out by forming a seal around the hole, as well as ensuring that water vapor cannot penetrate through cracks and holes in your siding.

If you choose to use a commercial spray can of primer or paint, be sure to give plenty of time for the material to dry before moving on with this process (the label will specify how long it takes). 

If using an oil-based product such as linseed oil or varnish does not need drying time; however, it’s best if you let it sit for at least 24 hours so that everything dries properly before moving on with anything else.

Gently Sand Away Excess Cement And Prime (If Needed)

After you have applied the patch, you may notice that the gap is still visible. If this happens, it’s a good idea to gently sand away any excess cement using fine-grit sandpaper. You can use a paintbrush to apply the primer and then roll on your paint using a roller. 

Make sure not to apply too much paint because this will cause it to bleed through your siding and make matters worse! Don’t use any type of primer on the back side of your siding either; it will create an uneven surface that creates more problems than it fixes!

Remove Any Damaged Or Loose Siding Pieces

If there are any loose pieces, use a pry bar or hammer to remove them and then fill the gaps with new siding. 

If the damage is severe, you may need to replace more than just a few pieces of siding. In this case, call a professional who can assess your house and give you an estimate on how much it will cost to fix the problem appropriately.

Apply New Siding And Sealant (If Needed)

Now that you have replaced the rotted wood and applied a new layer of siding, you should apply some sealant to ensure that moisture doesn’t get in through the hole again. 

If your home is older, or had an original coat of paint on it when you bought it, chances are good that there is no caulk installed around your windows and doors. 

If this is the case for you, then apply new caulk along the edge of your trim pieces before installing them back into place. 

You can use either an acrylic or silicone-based sealant for this step—the choice will depend greatly on what type of paint job you plan on doing in order to conceal any imperfections created by applying new siding over old lumber

Use A Water Hose To Clean Off Excess Material From The Siding

Once you’ve cleaned up the area, you may need to remove any remaining material. You can use a brush, pressure washer, sponge or putty knife to do this.

Apply Caulking Around The Perimeter Of Where You Applied Your Patching Compound (If Needed)

After you’ve applied your patching compound, use a caulking gun to apply a bead of silicone caulk around the perimeter of where you applied it. 

This will help keep water out and make sure that your patch is secure. If a hole hasn’t been patched with caulking, chances are that it will come loose over time and need to be repaired again.

Allow Drying Time Before Adding More Patches Or Painting Over It

Make sure the patching compound is completely dry before adding a second layer of filler or painting over it. It should be dry in 24 hours to begin with, so give it time to do its job. If you need to paint over the patched hole, allow it to dry for another 48 hours before adding another layer of paint and/or primer.


So there you have it, 15 easy steps to repairing a hole in the siding on your home. It’s not something that should be done on your own unless you are an expert at this kind of thing.
