How to Repair Garage Door Dentsby Ryan Malone
Aluminum and steel garage doors may require less maintenance than wooden or fiberglass doors, but they can dent much more easily. If you’ve bumped into your garage with your car or if it’s taken a beating from your kids playing ballgames, you may feel the urge to buy a completely new door. But replacement isn’t your only option. Dents are easy to eliminate with nothing more than drastic temperature change.
Items you will need
- Dish-washing soap
- Aluminum foil
- Cigarette lighter
- Compressed air canister
Fill a bucket with water and add 1 teaspoon of dish-washing soap. Soak a sponge in the water and wipe it over the surface of the dent. Rinse the dent with clean water, and wait for it to dry.
Cut off a section of aluminum foil and lay it flat over the dent. Hold one side to keep it securely in place.
Light your lighter and move the flame over the foil for at least 60 seconds. Make sure you move at a steady speed for even heat coverage. Remove the aluminum foil.
Hold your air canister upside down over the dent. Spray air onto the dent for at least 30 seconds. Make sure you keep the can upside down for the entire time -- it will release carbon dioxide, which is the key ingredient.
Wait for approximately two minutes. The dented area should pop back into place.
Clean the spot where your dent used to be with a sponge and clean water.
Repeat the entire process if the dent doesn’t pop back into place. Sometimes large dents require a little extra encouragement.
- If you don’t have a cigarette lighter or aluminum foil, use a hair dryer to heat the surface of the dent.
- Do the repair when the weather is mild and sunny. Dents are harder to fix on windy and rainy days, because it’s difficult to get the aluminum foil to heat up efficiently.
- Wear flame gloves to protect your hands.
