Garage Door Sealing Solutions: How to Weather-seal a Garage Door
Garage door weatherstripping and garage door sealing solutions are an essential aspect of garage door installation and maintenance. If your door isn’t weather-stripped properly, you put your garage at risk of animal invasion and unfavorable weather conditions.
In this guide, learn all you need to know about weather-stripping your garage door and how you can get your garage door to seal better.
How Can I Get My Garage Door to Seal Better?
Getting your garage door to seal better involves a process of doubling or replacing the bottom door seal. You also have to replace or fortify the weatherstripping on the molding along the top and sides of the door.

Here are the different types of garage door seals you can use to let your garage door to seal better:
Types of Garage Door Sealing

The function of a threshold seal is similar to that of the bottom seal found on a garage door. However, threshold seals are attached to the floor instead of the door.
These seals can be used in conjunction with a door seal or used alone. Their purpose usually is to keep out surface water in driveways that slope towards a garage. You can also use them to fill large gaps below garage doors.
If you find a good-quality vinyl threshold seal, it is usually more durable than a regular door seal. Vinyl deals often come with adhesives included for their installation.
You must remember that thresholds prevent water from going out of a garage, the same way they keep it from flowing in. You might find this design inconvenient if you like to hose out your garage. Having a threshold makes it difficult for you to keep debris and dirt out of your garage.
2. Garage Door Bottom Seal
The seal in the garage door bottom (also known as door sweep) is a long piece of vinyl or rubber. This piece is usually attached to the edge of the garage door bottom.
The seal is made from a flexible material that compresses when the door is closed. This compression causes the gap along the floor to ea, keeping out dirt, critters, water, and cold breezes. Once you notice daylight peeking through the bottom of the closed door, you’ll know it’s time for a seal replacement.

For installation, make use of screws or galvanized nails. The door frame of the garage door should press against the garage door while weatherstripping to create a secure seal.
4. Vinyl Door Strip With Integrated Weatherstrip
An excellent option for damaged, old or rotted doors is door stop molding with weatherstripping. This type of door molding is made of vinyl with a flexible weather seal flange and a wood-look molding strip.
It can be easily cut with a saw and installed with stainless steel or galvanized siding nails. To install, begin by positioning each piece parallel to the door face, then push the molding towards the door to compress the weatherstrip flange slightly against the door. Next, fasten the molding to the door jamb using nails.
Ideally, it is best to install the top molding first before overlapping the top molding ends with the stops at the sides.
