Garage Door Repair 101: Fixing the Bottom Seal

The bottom seal on your garage door primarily serves two functions: it protects the bottom of your garage door when you lower it to the floor, and it provides a seal against animals and weather. Overtime, the rubber materials will wear out, creating tiny openings that allow dirt, debris, and rainwater to blow into the garage.

Considering how much water Rancho Cordova gets during the rainy season, you definitely want to make sure your garage door bottom seal is in good shape. If it’s worn with holes for weather and animals to get in, you’ll need to replace it. You could hire a professional, or with a few inexpensive supplies and a couple of hours in an afternoon, fix it yourself. It is a fairly easy DIY household repair job.

Measure the Door

Start by measuring the length of the door. You’ll want to purchase a gasket seal that has at least six inches more than the length of the door.

Removing Old Seal, Installing the New

Raise the door high enough to work on the bottom seal. Use a screwdriver to pry open the slots of the track on either end of the garage door. Straighten the tracks to make it easier to remove the old seal and add the new.

Pull the old seal off the door. If it doesn’t slide easily, cut it into pieces using a utility knife.

Clean the bottom of the door. Remove debris from the tracks holding the weatherstripping.

Coat both sides of the track with a silicone spray, or a soapy water mixture, to lubricate the track.

Fold the new seal in half. Slide the seal across both sides of the track, pushing the bottom three inches beyond the end of the track. Cut the extra three inches of the seal.
