How to Inexpensively Remove a Dent Small from a Garage Door

It is common for a garage door, at some point in its life, to become dented after the owner inadvertently hits it with their vehicle. Sometimes, the harsh weather can cause a tree branch to collide with the garage door, making a small dent. Repairing a small dent in a garage door can be done successfully by manipulating the tolerance in temperature of the door. Read on to find out how this is done.

Equipment Needed

For this repair job, you will need the following items and equipment:

  • Compressed air in a can
  • A standard lighter
  • Some heavy duty foil made from aluminium
  • Bucket of warm soapy water
  • Sponge

Clean the Door

It is imperative that you work with a clean garage door. Use the sponge and water to thoroughly clean the dented area, and immediately around this area as well. Allow to dry naturally or wipe dry with rags.

Cover With Foil

When the dented area is dry, take the aluminium foil and measure it out so that you can cover the whole of the dent with one piece of foil. Rip or cut the foil from its holder.

Heat the Area

This part of the repair uses the lighter to heat up the metal of the door at the dented area, so take care when doing this part. With one hand, hold the foil in place over the dent. Take the lighter, ignite it, and begin to heat up the foil and the dent. Continually move the lighter around the dented area for around a minute. This DIY fix will only work properly if the whole of the dent is heated.

Spray the Air

Once the area has been heated, quickly remove the foil and spray the compressed air into the area. It is absolutely vital that you turn the can upside down as you are spraying the air; spraying it in this position allows the carbon dioxide to be released. This is the trigger for the dent to move.

Watch the Dent Pop Back

If you have sufficiently heated and cooled the metal and dent, the two extremes of temperature should cause the metal to pop back into place, thereby removing the dent. If you are having difficulty, repeat the heating and cooling part of the repair to try to correct it.

If you are still having trouble or the dent is too large, you should consider hiring a professional like Best Doors to do the repair for you.

About Me

One door opens

The old saying is that when one door closes, another one opens. I find that once one door has been fitted and opened, another one seems to open right behind it. That's the life of a door fitter! People are so impressed when they come around to a friend or family member's house and they have a brand new door in place that they often go out hunting for a new door of their own. This site is a collection of the doors that I find inspiring in my travels - with lots of pictures of vintage doors and tips on techniques for hanging unusual doors. If you like doors, come inside.
