How to Fix a Bent Garage Door

Updated: 6 days ago


Encountering a bent garage door can be frustrating and impact the functionality and security of your home. But what causes these bends, and more importantly, how can you fix them? Before diving into the solutions, understanding the common reasons behind bent garage doors is crucial. From accidental bumps to environmental pressures, several factors can lead to this issue. 


Let's explore the causes and then move on to effective repair strategies to get your garage door back in perfect shape.


Causes of Bent Garage Doors

Garage doors can bend for several reasons, often resulting from direct impact or pressure. A common mistake that leads to a bent garage door is accidentally hitting it with a car. Sometimes homeowners close the garage door without realizing something is in its path, like a bicycle or trash bin, causing the lower section to warp.


Environmental factors also play a role in bending doors. Strong winds and storms have enough force to push against the panels and create bends or even cracks over time. Even regular wear and tear can weaken the structure of your garage door panels, especially if they are not maintained properly with lubrication and cleanliness checks.

Remembering these causes can help prevent future damage to your garage doors.

How to Fix a Bent Garage Door Panel





To fix a bent garage door panel, you can use a wooden mallet to hammer out the dent, fill in the dent with auto body filler, or replace the damaged panel altogether. 


These are simple and effective methods for repairing your garage door to its original state.


Hammering out the dent

Hammering out a dent in your garage door might seem daunting, but with some patience and the right technique, you can get it looking smooth again. Start by laying a piece of wood over the dented area to spread out the force and avoid further damage.



Gently tap the wood with a hammer from the opposite side of the dent. Keep your movements steady and controlled; overzealous pounding could worsen things.


For smaller dents, sometimes all it takes is frequent light taps to gradually work the metal back into place. Be mindful not to hit too hard – you're coaxing the metal back, not trying to make an impression on it.


Regular checks will help you see progress without going too far. After smoothing out most of the bend, follow up with sanding tools for refinements and paint to conceal any blemishes left behind.


Filling in the dent with auto body filler

Filling dents in a garage door can be like fixing a small dent on your car. Auto body filler is the magic ingredient that helps achieve a smooth surface where those unsightly dents used to be.

First, ensure the area around the dent is clean and dry before applying any filler. Next, mix the auto body filler according to the manufacturer's instructions; this usually involves combining a hardener with a resin.


Apply the mixed filler to the dent using a spatula or putty knife, spreading it evenly over and slightly beyond the damaged spot. You'll want enough filler to cover the dent completely but avoid piling it too thickly as it will make sanding more difficult later on.

Allow the filler to dry thoroughly; depending on temperature and humidity levels, this could take anywhere from 20 minutes to an hour.


Once dried, grab your sanding tools for shaping and smoothing out that hardened filler until it blends seamlessly with your garage door’s original contour. Sand in stages, starting with coarse-grit paper and working toward fine-grit for that perfect finish ready for priming and painting—the final touches in disguising any sign of repair work!


Replacing the damaged panel

Sometimes, a bent garage door panel is beyond repair. In such cases, replacing the damaged panel might be your best option to fix your bent garage door. Start by securing a new panel that matches your current garage door.


You'll need to detach the damaged one from the tracks and remove any hinges or rollers attached to it.


Install the new panel carefully, attaching it first at the top and then working your way down, making sure each part aligns correctly with your garage door system. Once in place, reattach all hardware – hinges and rollers – and ensure everything is tight and secure before trying out your garage door opener again.


This process restores not just functionality but also boosts curb appeal with a dent-free look.


Tools Needed for Garage Door Panel Replacement



To fix a bent garage door panel, you will need a wooden mallet to hammer out the dent, auto body filler to fill in the dent, sanding tools for smoothing, and paint to match the color of your garage door.


These tools are essential for ensuring a successful repair of any damaged panels.


Wooden mallet

To fix a bent garage door panel, you'll need a wooden mallet to gently tap out the dents. Start by positioning the mallet against the backside of the damaged area and hitting it with controlled force to push out the dent.


Avoid using excessive strength to prevent further damage to the panel. The wooden mallet helps distribute the force evenly, effectively restoring the shape of your garage door without causing additional harm.


If using a hammer, place a piece of wood over the affected area before making any strikes.


Auto body filler

To fix a bent garage door panel, use auto body filler. After hammering out the dent and ensuring the surface is clean and dry, apply the filler to fill in the damaged area. Smooth it out with sandpaper once it's dried, then paint over it to match the rest of the door.


Auto body filler is an effective solution for repairing minor dents in your garage door panels.

When using auto body filler on your garage door panels, be sure to follow all safety precautions and manufacturer's instructions. This will help ensure a successful repair that restores both function and aesthetics to your garage door.


Sanding tools

Once the auto body filler has been applied and dried, the next step in fixing a bent garage door panel involves using sanding tools. These tools are used to smooth out the surface of the filled area, ensuring that it blends seamlessly with the rest of the panel.



Sanding tools such as sandpaper or an electric sander can be used to carefully remove any excess filler and create a uniform surface for painting. Properly sanding down the filled area is crucial for achieving a professional-looking finish and restoring your garage door to its original condition.

After inspecting rollers and tracks and replacing damaged panels, having sanding tools at hand ensures you can achieve a smooth surface before applying paint. Regularly inspecting for damages, lubricating hinges and tracks, keeping the door clean from debris, will help prevent future damage to your garage door.


Paint

After smoothing out the surface with sanding tools, the next step is to apply a fresh coat of paint to the repaired garage door panel. Using a high-quality paint that matches the color of your garage door will help blend the repair seamlessly.



Apply thin, even coats of paint and allow each layer to dry completely before applying another one. This will ensure a smooth and professional-looking finish that will protect your door from rust and damage.

Once you have finished painting the repaired area, give it time to fully dry before reattaching it to your garage door. The new coat of paint not only restores the appearance of your door but also provides an extra layer of protection against future wear and tear.

How to Fix a Bent Garage Door Yourself



Inspecting rollers and tracks is the first step to fixing a bent garage door yourself. You can also use suction cups or heat to remove dents, and replace damaged panels if necessary.

Inspecting rollers and tracks

To ensure your garage door is in optimal condition, regularly inspect the rollers and tracks. Here are the steps to perform this inspection:

  1. Use a flashlight to get a good look at the rollers and tracks for any signs of wear or damage.

  2. Check for any debris or buildup that could affect the smooth operation of the garage door.

  3. Tighten any loose bolts or screws on the roller brackets and tracks to prevent further damage.

  4. Look for any dents or bends that may hinder the proper functioning of the door.


Using suction cups or heat to remove dents

Heat can be applied to the dented area using a hair dryer or a heat gun. This will make the metal more flexible and easier to reshape back into place, especially for smaller dents.

Alternatively, suction cups can also be used to pull out the dent by creating a vacuum seal and gently pulling on the affected area.


Ensuring that these methods are performed with caution is crucial in order to avoid causing further damage to the garage door panel. It's important to approach this task delicately as excessive force could worsen the dent or cause cracks in the metal.


Replacing damaged panels

To continue with fixing a bent garage door, when hammering out or filling in the dents isn't possible, replacing the damaged panel becomes necessary. This process involves removing the old panel and installing a new one in its place.


It may require some DIY skills or professional help, depending on your comfort level and the extent of damage to your garage door.


When it comes to tackling this task yourself, you'll need to have different tools at hand. A wooden mallet will be essential for gently tapping the new panel into place without causing further damage.


Tips for Garage Door Maintenance and Upkeep



Regularly inspecting your garage door for damages, properly lubricating hinges and tracks, keeping the door clean and free from debris, and calling for professional help when needed are essential for maintaining a functioning garage door.


Regularly inspecting for damages

Inspect your garage door frequently for any signs of damage. Look for dents, cracks, or misalignments in the panels and tracks. Detecting issues early can prevent further complications and costly repairs.


Keep an eye out for rust on metal components and listen for unusual sounds during operation. Regular maintenance helps to prolong the lifespan of your garage door and ensures its safe and efficient performance.


Maintaining a schedule for inspecting your garage door is essential to catch potential problems before they escalate. By proactively identifying issues, you can address them promptly and avoid inconvenience or safety hazards down the line.


Properly lubricating hinges and tracks

Lubricate hinges and tracks regularly to maintain smooth operation. Apply a silicone-based lubricant to all moving parts, including roller bearings, hinges, and springs. This reduces friction and prevents premature wear and tear.


When lubricating the tracks, wipe away any debris or buildup to ensure the door moves freely along its path.



Regular maintenance of hinges and tracks helps prevent costly repairs in the future. Aim for quarterly lubrication or whenever you notice squeaking or sticking while operating the garage door.

Keeping the door clean and free from debris

Regularly cleaning out the garage door tracks prevents dirt and debris from accumulating, which can affect the door's operation. By using a vacuum or damp cloth to remove any buildup, you can maintain smooth functioning and avoid potential damage.


Clearing away leaves, cobwebs, and other obstructions around the garage door helps to prevent them from jamming the mechanism or causing misalignment. Regular maintenance in this area ensures optimal performance and extends the lifespan of your garage door system.


Calling for professional help when needed.

It's important to recognize when the damage to your garage door is beyond your DIY abilities. If you find that the problem is too complex or requires specialized skills and tools, don't hesitate to seek help from a professional garage door repair service.


They have the expertise and experience to tackle even the most challenging issues with your garage door, ensuring it is fixed correctly and safely. By enlisting their assistance, you can save time and avoid potential accidents or further damage to your garage door.


Remembering "calling professional help" will save you- costly mistakes down the road.
