The Benefits of a Garage Door Seal

After finding a garage door that is best for your home, you may want to consider adding a garage door seal to complete the new addition to your home. Not only will it protect your home, garage and garage door from insects and rodents finding their way in, it also protects against inclement weather, which can ruin the interior and parts of the exterior of your garage and hurt its functionality.

What Is a Garage Door Seal?

A garage door seal is a piece of rubber or vinyl that constricts when the garage door closes minimizing the entrance and exit of any elements such as oil, water, debris or insects. It will also prevent warm or cold temperatures from escaping your garage. They are also referred to as garage door thresholds or weather strips. Not only is the garage door able to be sealed at the bottom, the frame of the garage door can also be sealed. Sealing the frame of the garage in addition to the bottom will offer far better protection against the elements and pests.

Signs You Need One

If it seems like your garage is abnormally cold during the winter or extremely hot during warmer months, you probably need a garage door seal. Other signs you need one include precipitation from rain or snow or the presence of insects or rodents in your garage. If you have a seal and notice any of these signs, it may signal that the seal needs to be replaced or repaired.

Before You Buy

The first thing you’ll need to do is measure your garage door so you can buy the correct length for your garage. You should also check to see if the space between your garage and the ground is uneven. A garage door seal should fit perfectly between your garage and the surface that it meets, so you will need to compensate for any unevenness.

Next, examine the look of your home. You want a seal that matches the design and look of your home. The location of your home will also determine what type of material is best for you. If you live in a warmer climate, a vinyl seal is generally the best choice. A rubber seal may melt due to high temperatures. However, a cold climate may cause vinyl to become stiff, crack or create unexpected gaps, inviting elements into your garage. For a cold climate, a rubber seal is the best option.

A single piece is more likely to create an accurate fit. If you use multiple pieces, the places where they meet may throw off your measurements, as well as creating weak points in the seal itself.


Just as with your garage in general, proper maintenance is essential to the functionality and longevity of your garage door seal. Make sure that all mechanisms are regularly lubricated and wiped down. Improperly closing the garage door can ruin a seal over time. You should check your garage door seal once a year to make sure that a replacement is not needed and to identify minor damage before it becomes major.
