How To Seal Garage Door Gaps

Garage door gaps can be a major source of energy loss in your home. By sealing these gaps, you can save money on your energy bills and make your home more comfortable. There are a few different ways to seal garage door gaps, and the best method for you will depend on the type of door you have and the size of the gaps.

Types of Garage Door Gaps

There are two main types of garage door gaps: weatherstripping gaps and header gaps. Weatherstripping gaps are the spaces between the door and the frame, and header gaps are the spaces between the door and the header (the top of the door opening). Both types of gaps can allow air and water to enter your garage, but weatherstripping gaps are typically the more significant source of energy loss.

How to Seal Weatherstripping Gaps

There are a few different ways to seal weatherstripping gaps, but the most common method is to use weatherstripping tape. Weatherstripping tape is a self-adhesive foam tape that is applied to the door frame and the door itself. It helps to seal the gaps between the door and the frame, preventing air and water from entering your garage.

To install weatherstripping tape, simply clean the door frame and the door itself, then apply the tape to the frame. Be sure to press the tape firmly into place so that it creates a good seal. You can also use caulk to seal any gaps around the weatherstripping tape.

How to Seal Header Gaps

Header gaps are typically sealed with caulk. Caulk is a flexible sealant that can be applied to fill gaps and cracks. To seal a header gap, simply apply a bead of caulk to the gap and smooth it out with your finger. You can also use a caulk gun to apply caulk more evenly.

Other Ways to Seal Garage Door Gaps

In addition to using weatherstripping tape and caulk, there are a few other ways to seal garage door gaps. These methods include:

Installing a garage door weatherstrip. A garage door weatherstrip is a flexible seal that is installed on the bottom of the door. It helps to seal the gap between the door and the floor, preventing air and water from entering your garage.
Installing a garage door header seal. A garage door header seal is a flexible seal that is installed on the top of the door. It helps to seal the gap between the door and the header, preventing air and water from entering your garage.
Using expanding foam. Expanding foam is a type of sealant that expands to fill gaps and cracks. It can be used to seal gaps around garage doors, windows, and other openings.

Choosing the Best Method for You

The best method for sealing garage door gaps will depend on the type of door you have and the size of the gaps. If you have a small gap, you may be able to seal it with weatherstripping tape or caulk. If you have a larger gap, you may need to use expanding foam or a garage door weatherstrip.

No matter which method you choose, it is important to do a good job of sealing the gaps. By doing so, you can save money on your energy bills and make your home more comfortable.
