How to Seal Garage Door Gaps at the Bottom
Bottom Seals
You must attach bottom seals to your garage door’s bottom. Go for a universal bottom seal or manufacturer-recommended product. But before you apply the seal, be sure to do so on a clean garage door free from dirt.
Floor Seals
The threshold seal is the best product to close the gap between the garage door and the floor. It helps avoid any tripping hazard. Create an outline using chalk or marker on the floor where your door will sit. The next step is to lift the door and follow the instructions to install the seal. Finally, lower the garage door after successful installation.
