How to Keep a Garage Door From Sticking to a Concrete Floor

If you’ve ever had your garage door stick to the floor when you try to open it, you know how frustrating it can be. Luckily, you can do a few things to prevent this from happening. This article will discuss how to keep a garage door from sticking to a concrete floor. Read on to learn more!

How to Keep a Garage Door From Sticking to a Concrete Floor

Garage doors are often made of metal, and when they come into contact with a concrete floor, they can stick. The concrete can heat up and expand while the metal garage door remains cool.

This can often cause the garage door to become distorted and difficult to open. If you live in an area with extreme temperature changes, this is especially important to keep in mind. To prevent your garage door from sticking, you can try a few simple steps.

Summary: To prevent a garage door from sticking to a concrete floor, there are a few steps you can take. Firstly, ensure that the concrete surface is clean and free of any debris that may cause friction or obstruction. Secondly, apply a lubricant such as silicone spray or garage door lubricant to the tracks and rollers of the garage door, applying it sparingly to prevent buildup.

What Makes a Garage Door Stick?

A garage door sticking to a concrete floor can be a real nuisance. It’s unsightly, but it can also be dangerous if the door is not aligned correctly. Several things can cause a garage door to stick to a concrete floor, including:

  • Moisture: If the garage floor is damp or wet, it can cause the door to stick.
  • Debris: If there is debris on the floor, such as leaves or dirt, it can get caught under the door and cause it to stick.
  • Temperature: Extreme temperature changes can cause the door to expand or contract, which can cause it to stick.


Prevention is the best way to keep a garage door from sticking to a concrete floor. There are a few things you can do to help prevent this from happening:

Sticking to a Concrete  Floor
  • Make sure the concrete is sealed and treated so that it is not as slick
  • Apply a coat of oil or wax to the concrete floor
  • Install rubber mats or runners on the concrete floor near the garage door. This will help to create a barrier between the door and the floor.
  • If possible, keep the garage door cracked open when it is not in use. This will allow air to circulate and will help to prevent the concrete from getting too slick.

A Step by Step Guide on How to Keep a Garage Door From Sticking to a Concrete Floor

Step 1: Identify the Source of the Problem

Begin by carefully examining your garage door and the surrounding area to pinpoint the issue causing the door to stick. It could be due to accumulated dirt, debris, or moisture, or even due to a misaligned track or damaged weatherstripping. Understanding the root of the problem will help you determine the most effective solution.

Step 2: Clean the Garage Door and Concrete Floor

Regular cleaning is essential in preventing garage doors from sticking to concrete floors. Use a broom to sweep away dirt and debris from the garage door’s tracks, rollers, and the floor area. Then, use a wet cloth or sponge with a mild detergent to clean the garage door panels, tracks, and floor, removing any stubborn grime that may be causing friction. Rinse the area thoroughly and allow it to dry completely.

Step 3: Lubricate the Garage Door’s Moving Parts

Lubrication is vital in maintaining the smooth operation of your garage door. Apply a high-quality garage door lubricant, such as silicone or lithium-based grease, to the door’s rollers, hinges, and tracks. Be sure to wipe away any excess lubricant to avoid attracting dirt or debris. Regular lubrication can significantly reduce friction between the door and the concrete floor, preventing sticking.

Step 4: Check and Adjust the Garage Door’s Balance

An unbalanced garage door can cause it to stick to the floor. To check the balance, disconnect the garage door opener and manually lift the door halfway. If it stays in place, it’s properly balanced. If it moves up or down, it’s unbalanced and needs adjustment. Consult your garage door’s manual for guidance on how to make these adjustments, or hire a professional to handle the task.

Step 5: Inspect and Repair Weatherstripping

The weatherstripping at the bottom of your garage door helps create a seal between the door and the floor, preventing drafts, water, and pests from entering. Damaged or worn weatherstripping can cause the door to stick to the concrete floor, especially during wet or humid conditions. Inspect the weatherstripping for signs of damage, and replace it if necessary to create a tight seal and avoid sticking.

Step 6: Seal the Concrete Floor

Sealing the concrete floor can prevent moisture from causing the garage door to stick. First, clean the floor thoroughly and repair any cracks or damage. Then, apply a concrete sealer following the manufacturer’s instructions. Be sure to allow the sealer to dry completely before using the garage. A properly sealed floor can help prevent the door from sticking and prolong the life of your garage floor.

Step 7: Adjust the Garage Door Opener’s Sensitivity

If your garage door opener’s sensitivity is set too high, it may cause the door to stick to the floor. Consult your garage door opener’s manual for instructions on how to adjust the sensitivity settings. Make small adjustments and test the door’s operation until it no longer sticks.

Step 8: Inspect and Repair the Garage Door’s Tracks

Misaligned or damaged tracks can cause the garage door to stick to the floor. Inspect the tracks for signs of damage, such as dents or rust, and repair or replace them as needed. Additionally, use a level to ensure the tracks are properly aligned. If they’re misaligned, loosen the brackets holding the tracks in place and adjust them until they’re level. Tighten the brackets and test the door’s operation.

Step 9: Maintain Regular Inspections and Maintenance

To keep your garage door from sticking to the concrete floor, it’s essential to perform regular inspections and maintenance. Check for signs of wear or damage to the door, tracks, rollers, and weatherstripping, and address any issues as needed. Regular maintenance, including cleaning, lubrication, and adjustments, can help prevent future sticking and prolong the life of your garage door system.

Step 10: Keep the Area Around the Garage Door Clear

Make sure the area around your garage door is free of debris, such as leaves, dirt, or snow, which can cause the door to stick to the concrete floor. Regularly sweep or remove any obstructions to ensure smooth operation and reduce the chances of sticking.

Step 11: Control Humidity in the Garage

High humidity levels can cause the garage door to stick to the concrete floor. To control humidity, install a dehumidifier in your garage, or consider using a moisture-absorbing product, such as desiccant packs or silica gel. Proper ventilation can also help reduce humidity, so ensure your garage has adequate airflow.

Step 12: Inspect and Replace Garage Door Springs

Garage door springs are responsible for counterbalancing the weight of the door, allowing it to open and close smoothly. Worn or damaged springs can cause the door to stick to the floor. Inspect your garage door springs for signs of wear or damage, and replace them as needed. Note that working with garage door springs can be dangerous, so if you’re unsure about performing this task, it’s best to hire a professional.

Step 13: Check for Concrete Floor Irregularities

Uneven or sloping concrete floors can cause the garage door to stick. Inspect the floor for irregularities, such as high spots, cracks, or depressions. If you find any issues, consider hiring a professional to level or repair the floor.

Step 14: Insulate Your Garage Door

An insulated garage door can help prevent sticking caused by temperature fluctuations and condensation. Insulating your garage door can also improve energy efficiency and reduce noise. Consider adding insulation to your existing door or upgrading to an insulated garage door model.

By following these steps, you can effectively prevent your garage door from sticking to the concrete floor. Regular maintenance, inspections, and addressing any issues as they arise can ensure smooth operation and prolong the life of your garage door system.

Clean Up Any Spills or Messes

If you have a concrete floor in your garage, it’s essential to keep it clean and free of clutter. This will help reduce the risk of your garage door sticking to the concrete. In addition, make sure not to park your car in the same spot repeatedly. The constant weight of the vehicle will cause the concrete to sink, which can lead to your garage door sticking.


Garage door opener maintenance is essential to prevent the door from sticking. You can lubricate the tracks and rollers with a silicone spray or WD-40. If the door still sticks, you may need to adjust the hinges or replace the rollers. By following these simple steps on how to keep a garage door from sticking to a concrete floor, you can keep your garage door functioning properly and avoid any costly repairs.
