How to Fix a Bent Garage Door


It’s actually quite easy to make a dent in a garage door: homeowners do it all the time! Either they pull out of the garage without looking and knock into the closed garage door, or they simply bump into the garage door by parking too close to it. It happens far more often than you might think.

Additionally, garage door panels can be damaged from fallen debris, hailstorms, wind storms, and any number of natural events. Provided the damage to the garage door panel is minor, you shouldn’t need to call in a professional just to fix a bent garage door.

In most cases, fixing a bent garage door is quite simple and quick:

Hammering Out the Bend or Dent

In a bent garage door, more often than not, the damage is limited to 1 panel. In these cases – or even if the bend extends to 3 or 4 panels – the necessary repair can be made with a simple hammer.

You don’t want to strike the bent garage door directly with the hammer, however – that could cause scratches and even further bending. Instead, you will want to place a block of wood on the dent – it doesn’t need to be thick – and hammer the block, using it as a buffer or shock absorber for the taps of your hammer.

Be careful not to hammer the side of the door the bend originated from. In other words, place the block of wood where the bend or dent protrudes outward. If the damage was caused when you hit your garage door from the inside, you will want to place the block of wood on the outside of the bent garage door.

Make sure to hold the block of wood tight against the bent garage door. You’ll want to make sure the block doesn’t move or scrape against the garage door panel. The function of the block is to keep the garage door from being scratched or further damaged, but strategically placed strikes of the hammer against the block of wood should get the bent garage door back into shape.

You shouldn’t need to apply much force when hammering the bent panel back into its original form. Start with soft taps and only increase the force as needed.

Filling In the Dent

If the dent or bend in the garage door isn’t preventing the garage door from opening and closing properly but you wish to repair it for aesthetic purposes, you could try filling in the dent. This will restore the smooth appearance of the garage door panel.

First, you will want to begin by sanding down the dented area. This will prevent any jagged fragments – as tiny as they may be – from causing potential fissures or cracks in your repair job down the line.

Once you’ve sanded down the dented area, use auto body filler to fill in the dented space. Some auto body fillers need to be mixed with a hardening agent. Check out this website for a list of auto body fillers and select the one that best meets your needs in conjunction with the material your garage door panel is made from.

Apply the auto body filler and smooth it down as best you can. Then, once it has dried, sand it down and apply a coat of paint so that it matches the color of your garage door panel. You may want to paint the entire door to ensure an even color and keep the dent completely hidden from sight.

If you’re unable to fix a bent garage door by simply hammering out the dent or filling it in, you will need to replace the damaged panel.

While you are removing hinges and replacing a damaged garage door panel, this is an opportunity for you to get a good look at the garage door rollers. Depending on how often you use your garage door and depending on the quality of the rollers, you should replace your garage door rollers every 6 – 12 years.

As always, if you don’t feel up to the task, or if your door or rollers need replacing, let the experts handle it. Call Midlothian Garage Doors, and we will get you fixed up in no time.
