Installing a garage door bottom seal is an essential step in maintaining the functionality and energy efficiency of your garage.

In this article, we will guide you through the process of installing a garage door bottom seal, providing you with the necessary steps and tips to complete the task effectively.

Gather the Materials

Before you begin the installation process, it’s important to gather all the necessary materials. This will ensure a smooth and efficient installation. The materials you will need include:

  • Garage door bottom seal: Choose a seal that is compatible with your specific garage door type and size.
  • Measuring tape: This will help you accurately measure the length of the seal needed.
  • Scissors or utility knife: You will need these to cut the seal to the appropriate length.
  • Screwdriver: Depending on your garage door, you may need a screwdriver to remove the existing seal or to secure the new seal in place.
  • Cleaning supplies: It’s a good idea to clean the bottom of your garage door before installing the new seal to ensure proper adhesion.

Remove the Old Seal (if applicable)

If your garage door already has a bottom seal that needs replacement, start by removing it. Use a screwdriver to loosen and remove any screws holding the old seal in place. Once the screws are removed, carefully pull the seal away from the bottom of the door. Clean the area thoroughly to remove any debris or adhesive residue.

Measure and Cut the New Seal

Using a measuring tape, measure the length of your garage door from one end to the other. Add a few extra inches to account for any overlap. This will ensure a tight and secure seal. Once you have the measurement, use scissors or a utility knife to cut the new seal to the appropriate length.

Attach the New Seal

With the new seal cut to size, it’s time to attach it to the bottom of your garage door. Start by positioning the seal at one end of the door and aligning it with the edge. Press firmly to ensure proper adhesion. Continue attaching the seal along the bottom of the door, pressing it firmly and evenly as you go. If your seal comes with screws or clips, use a screwdriver to secure them in place according to the manufacturer’s instructions.

Test the Seal

Once the new seal is securely attached, it’s important to test its effectiveness. Close the garage door and observe if there are any gaps or areas where the seal is not making proper contact with the ground. If you notice any issues, adjust the seal as necessary to ensure a tight seal all around.

Regular Maintenance

To prolong the lifespan of your garage door bottom seal, it’s important to perform regular maintenance. Inspect the seal periodically for any signs of wear or damage. Clean it with mild soap and water to remove any dirt or debris that may affect its performance. If you notice any significant damage or deterioration, consider replacing the seal to maintain optimal functionality.


Installing a garage door bottom seal is a relatively simple task that can greatly improve the functionality and energy efficiency of your garage. By following the steps outlined in this article, you can ensure a proper installation that will keep out dirt, pests, and drafts. Regular maintenance and inspection will help to prolong the lifespan of the seal, ensuring its effectiveness for years to come.
