Garage Door Threshold Seal

Sometimes the floor underneath the garage door is too uneven for a bottom seal to close all the gaps. A good remedy is a garage door threshold seal on the floor.

Usually made of rubber or vinyl, the threshold elevates in the middle and tapers off on both sides. It’s tough enough to withstand vehicular traffic. When installed correctly, it effectively seals the bottom of the door all by itself. It’s more effective when used with a bottom seal.

It’s even easier to install a threshold than a door seal. Cut it to length, position it, mark the outline, spread adhesive in the outline and set the threshold in the adhesive. Seat it firmly with a few taps with a hammer.
