Replace Garage Door Seal Bottom

A worn or damaged garage door seal at the bottom can let in water, pests, and cold air. Replacing it is an easy and inexpensive DIY project that can improve the energy efficiency of your home and extend the life of your garage door. Here's a step-by-step guide:

Materials You'll Need:

New garage door bottom seal
Measuring tape
Utility knife
Rubber mallet
Caulk gun
Caulk
Screws (optional)

Step 1: Measure the Garage Door Bottom

Measure the length of the bottom edge of your garage door from one side to the other. Add 1 inch to the measurement for overlap.

Step 2: Cut the New Seal

Cut the new seal to the length you measured in Step 1. If the seal has a flange, cut it off so that it will fit flush against the bottom of the door.

Step 3: Remove the Old Seal

Use a utility knife to carefully cut and remove the old seal from the bottom of the garage door. Be careful not to damage the door itself.

Step 4: Clean the Garage Door Bottom

Use a damp cloth to clean the bottom of the garage door where the new seal will be installed. Remove any dirt, debris, or old caulk.

Step 5: Apply Caulk

Apply a thin bead of caulk along the bottom edge of the garage door, where the new seal will be installed. This will help to keep the seal in place and prevent water from leaking in.
