How to get dent out of garage door?


Dents in garage doors can be unsightly and may affect the overall appearance and functionality of your garage. Whether the dent is caused by an accidental impact or extreme weather conditions, it’s important to address the issue promptly. In this article, we will explore various methods and techniques to effectively remove dents from garage doors.

Assessing the Damage

Before attempting to fix the dent, it’s crucial to assess the extent of the damage. Minor dents can often be repaired using simple DIY methods, while larger or more severe dents may require professional intervention. Carefully examine the dent to determine its size, depth, and location on the garage door.

Materials Needed

Materials used:
– Plunger or suction cup
– Heat source (hairdryer or heat gun)
– Dry ice or compressed air
– Rubber mallet or hammer
– Wooden block or dolly
– Aluminum foil
– Boiling water
– Automotive body filler
– Sandpaper
– Paint and primer (if necessary)

Methods for Removing Dents

1. Plunger or Suction Cup Method: This method is suitable for smaller, shallow dents. Place the plunger or suction cup over the dent and firmly push or pull to create suction. Gently twist the plunger or cup to release the dent.

2. Heat and Cold Method: For metal garage doors, heat and cold can help reshape the dented area. Use a heat source, such as a hairdryer or heat gun, to warm the dent for a few minutes. Then, quickly apply dry ice or compressed air to the same spot. The rapid change in temperature can cause the metal to contract and pop the dent out.

3. Rubber Mallet or Hammer Method: This method is suitable for larger dents. Place a wooden block or dolly behind the dent to provide support. Using a rubber mallet or hammer, gently tap the dent from the opposite side until it pops out. Be cautious not to strike too hard, as it may cause further damage.

4. Boiling Water Method: This method is suitable for vinyl or plastic garage doors. Boil a pot of water and carefully pour it over the dented area. Use a gloved hand or plunger to push the dent out from the inside. The hot water softens the material, making it easier to reshape.

5. Automotive Body Filler Method: For more severe dents, you may need to use automotive body filler. Clean the dent and surrounding area thoroughly. Follow the manufacturer’s instructions to mix the filler and apply it to the dent. Once the filler has hardened, sand it down to achieve a smooth surface. Finally, apply paint and primer to match the color of your garage door.


Removing dents from a garage door can be a straightforward process if approached correctly. Assess the damage, gather the necessary materials, and choose the appropriate method based on the type and severity of the dent. Remember to exercise caution and seek professional help if needed. With the right techniques, your garage door can be restored to its original condition.
