How to Repair a Garage Door Dent in Aluminum Panels

repair garage door dentWe have noticed a surge in requests for aluminum garage door installations. Aluminum is sturdy, reliable, and looks especially good with contemporary-style homes. However, it’s also a softer type of metal, making them more prone to dents. Fortunately, we know of a DIY trick you can use to repair garage door dents.

Aluminum Garage Door Dent Repair: Step-By-Step Process

1. Wash the dented area using a mixture of water and dish soap. Wait until the surface is absolutely dry before proceeding to step two.

2. Cover the entire surface of the dent with a sheet of aluminum foil.

3. Apply a heat source over the dent for one minute; use a lighter or heat lamp.

4. Remove the foil and immediately spray the surface for 30 seconds using an air compressor. Hold the canister upside down; this helps distribute the cold air.

If this works, the dent will pop back in place. These steps, by the way, may also work for repairing surface dents on a vehicle.

Why This Works

The process is simply a matter of physics. The heat exposure followed by a sudden influx in cold air forces the aluminum molecules to return to the original form of least resistance. Keep in mind the steps only work for aluminum panels and not wood, vinyl or other metal types.

Other DIY Repairs

We wanted to share this DIY hack because it may repair minor cosmetic damage. However, we must strongly emphasize that any other form of garage repair requires a professional. This includes all functional issues involving the door’s intricate components, such as the torsion springs, hinges, rollers, and garage door opener.
