Weather Sealing of Garage Doors

double gdInsulated garage doors can help save energy by ensuring that the treated air from the home does not escape through the garage. However, another way in which treated air can leave the garage is through the gaps between the garage door and the top, sides, and floor. In order to reduce this leak and keep out insects and small animals you need to weather seal your garage doors.

Weather Seals

The top and sides of a garage door are sealed with PVC molding weather seals while the bottom is typically sealed with vinyl, rubber, or mold seal. Ideally, the garage door should close flush with the frame. However, this is rarely the case and there are small gaps between the garage door and the frame that are sufficient for treated air to leak out and insects and small animals to enter the garage. The PVC molding or the vinyl seal will have a flap that will insert between the door and the frame and ensure that the gaps are sealed.


Weather seals for a garage door have to be installed with care to ensure that they are effective. If the garage door already has a weather seal that has become compressed with use and, therefore, ineffective, the old seal will have to be removed before the new one can be installed. This can be time consuming and difficult for a single person to work on. This is especially so if the track for the old weather seal has to be removed.


Whether you use the garage only to park your vehicles or use it as additional storage space, the contents will be better preserved when moisture, insects, and small animals are kept out. This can be done by weather sealing the garage door. Additionally, by ensuring that air leaks are minimizes, this also reduces the energy bill.
