Garage Door Weatherstripping and Why You Need It

Written Jeff Beneke and published on

A garage door adds both security and access to your home. While a garage door can help control who comes in and out of your garage, it might not always be able to restrict what you can’t see, including small critters and hot or cold drafts. Fortunately, you have a solution. Garage door weatherstripping can seal these entry points and help keep out unwanted elements. Learn more about how weatherstripping works to protect your garage.

5 Ways to Weather-Seal a Garage Door

If you’ve noticed water, dirt, or rodent droppings in your garage, there’s a good chance the problem can be traced back to your garage door. Garage doors are very large, and while all come with a bottom seal to keep out water, wind, dirt, and unwanted intruders, the seals themselves can break down over time. In more extreme cases, the concrete floor or driveway apron under the door can shift, crack, or settle, creating large gaps under the door that standard seals can’t cover.

Weather-sealing a garage door usually involves a simple process of adding or replacing the bottom door seal and the weatherstripping on the stop molding along the sides and top of the door. It may also include adding thin weatherstripping between the door panels​ if you want to make the door as airtight as possible.
