How to Replace the Garage Door Bottom Seal

Once you have the necessary supplies, follow these five steps to learn how to replace a garage door seal.

1. Start with the Correct Seal

Measure twice and cut once is a good motto when learning how to replace a garage door bottom seal. Measure the dimensions of your garage door, so you choose the correct size of rubber seal to match. If you live in a colder region, consider silicone or vinyl seals, as they react better to extreme temperatures.

Measure the length, height, and width and record the measurements for reference later.  

2. Remove the Existing Seal

Your next step is to detach the existing seal, which won’t take long. If there is a track, try and slide the seal out. If screws hold the seal in place, remove the screws. 

Be sure to remove all traces of the old seal and wash the area with soapy water. 

3. Get Everything Ready for Installation

Fill in any holes in the door itself and clean it well if there is a track. Sweep the garage floor and clear it of obstacles. Then lower the garage door to a level that makes it easy to reach the seal and see what you’re doing. 

4. Place the New Seal

Your next step in replacing garage door weather stripping is to line up the seal with the door and install it. If you have no track, ensure it’s flush with the concrete floor and nail it.

If you have a track:

  • Fold the seal in half.
  • Line the T-sections of the seal up to the grooves in the track.
  • Slide it into place using one hand to fold the seal and the other to guide it. This task is much easier with a friend.
  • Lubricate the seal with silicone spray, wax, or soap to make this task easier.
  • You may need to straighten the track with the screwdriver.

5. Trim the Excess

Trim away any excess rubber with a utility knife. Keep it flush with the door’s edge or the track opening.

That’s how simple replacing garage door weather stripping is!
