How to fix dented garage door?


Garage doors are prone to getting dented due to various reasons, such as accidental impacts, extreme weather conditions, or wear and tear over time. A dented garage door not only affects the appearance of your property but can also hinder its functionality. However, fixing a dented garage door is not as complicated as it may seem. With the right tools and techniques, you can restore your garage door to its original condition. In this article, we will discuss how to fix a dented garage door effectively.

Assess the Damage

Before you start repairing the dented garage door, it is crucial to assess the extent of the damage. Minor dents can often be fixed using simple techniques, while larger dents may require professional assistance. Inspect the dented area closely and determine if the dent has caused any structural damage or if it has affected the door’s functionality.

Materials Needed

To fix a dented garage door, you will need the following materials:

1. Rubber Mallet: A rubber mallet is a useful tool for gently tapping out minor dents from the inside of the door.

2. Plunger: A plunger can be used to create suction and pull out small dents.

3. Heat Source: Applying heat to the dented area, such as with a hairdryer or heat gun, can help the metal regain its original shape.

4. Aluminum Foil: Aluminum foil can be used as a protective layer between the heat source and the garage door to prevent any damage.

Fixing Minor Dents

If you have identified the dents as minor, you can try fixing them yourself. Here’s a step-by-step process to fix minor dents in a garage door:

1. Clean the Area: Start by cleaning the dented area using a mild detergent and water. This will remove any dirt or debris that could interfere with the repair process.

2. Apply Heat: Use a hairdryer or heat gun to warm up the dented area. Move the heat source back and forth to evenly distribute the heat. Be cautious not to overheat the metal.

3. Use a Rubber Mallet: Once the dented area is heated, gently tap it from the inside with a rubber mallet. Start from the outer edges and work your way towards the center of the dent. This will gradually push the metal back into shape.

4. Check and Repeat: After each tap, check the progress and repeat the process if necessary. Be patient and avoid applying excessive force, as it may cause further damage.

Professional Assistance

In some cases, the dents may be too severe or the garage door may have sustained structural damage. In such situations, it is advisable to seek professional assistance. Garage door repair experts have the necessary tools, skills, and experience to fix complex dents and ensure the door’s proper functionality.


Fixing a dented garage door is a task that can be accomplished with the right tools and techniques. By assessing the damage, using the appropriate materials, and following the step-by-step process, you can restore your garage door to its original condition. However, for more severe dents or structural damage, it is recommended to consult a professional garage door repair service to ensure a safe and effective repair.
