Bottom Garage Door Seal Replacement

Replacing the bottom seal on your garage door is a relatively simple task that can be completed in a few hours with the right tools and materials. A damaged or worn-out bottom seal can let in water, dirt, and pests, and it can also make your garage door operate less efficiently. By replacing the bottom seal, you can help to keep your garage dry, clean, and secure.

Materials You'll Need

New bottom seal
Utility knife
Measuring tape
Pencil
Drill
Screws
Caulk gun
Caulk

Instructions

Remove the old bottom seal. Use a utility knife to carefully cut the old seal away from the bottom of the garage door. Be careful not to damage the door itself.
Measure the length of the bottom of the garage door. Use a measuring tape to determine the length of the new bottom seal that you need. Add a few inches to the measurement to allow for overlap.
Cut the new bottom seal to size. Use a utility knife to cut the new seal to the length that you measured. Be sure to make a clean, straight cut.
Place the new bottom seal in place. Position the new seal along the bottom of the garage door, overlapping the ends slightly. Use a pencil to mark the location of the screw holes on the seal.
Drill pilot holes. Use a drill to drill pilot holes at the marked locations. The pilot holes will help to prevent the screws from splitting the seal.
Screw the seal in place. Use screws to secure the seal to the bottom of the garage door. Be sure to drive the screws in straight and flush with the surface of the seal.
Caulk the seal. Apply a bead of caulk around the perimeter of the seal to help prevent water and air from leaking in.

Tips

Choose a bottom seal that is made of a durable material, such as rubber or vinyl.
Make sure that the new seal is the correct size for your garage door.
Take your time when installing the new seal, and be sure to follow the instructions carefully.
Inspect the bottom seal regularly, and replace it if it becomes damaged or worn out.
