DIY Garage Door Dent Repair

When your garage door is damaged, the curb appeal of your home suffers. This may not seem like a big issue, but if you are planning on selling your house in the future, it could be. If a buyer is looking at your home and sees dents in your garage, they may believe there are other things in your home that are neglected.

Not only that, but when your garage door isn’t functioning properly, you can’t enjoy the convenience and safety that comes with it.

If you have a large dent in your garage door, you probably will need to have it replaced. Fortunately, it’s possible to fix smaller dents in your garage door yourself and this is a quick and easy repair.

Repairing a small dent in your garage door requires materials you probably already have around the house. Choose your method based on the materials you have at home.

Method 1

You’ll Need: A wooden block, rubber mallet, putty knife, fine-grit sandpaper, patching material, paint, and primer.


Wash the area with warm water and detergent and allow it to dry completely.

Place the block of wood over the dent, then tap it with the mallet until the dent has evened out.

Sand the area until smooth.

Use the patching material to cover the site of the dent and make it even smoother using the putty knife. Once the putty dries, sand the area down again.

Apply primer, let it dry, then paint.

Method 2

You’ll Need: Compressed air, a heat source (such as a lighter), and aluminum foil


Wash the area with warm water and detergent and allow it to dry completely.

Place a strip of aluminum foil over the dent.

Use the heat source so it evenly heats up the foil.

After about a minute or so, remove the foil and spray the dent with the compressed air upside down for about 30 seconds.

Both of these repair methods are fast and easy. If you have a stubborn dent, though, they may not be enough. If that turns out to be the case, allow our skilled technicians to diagnose your problem and navigate you to the best solution. Let us take care of all your garage door needs.
