It’s often the smaller things that make the biggest impact on safety and convenience in the world of garage doors. One small component that plays a big role in your garage door experience is the garage door bottom seal. This seemingly simple strip running around the perimeter of your door can make a huge difference in protecting your garage from weather, annoying pests, and unnecessary energy loss.
At Good Day Garage Doors, we handle all your garage door needs, including garage door bottom seal replacement. In this guide, we’ll walk you through everything you need to know about weatherstripping and bottom seals, why they’re important, and when to call a team of garage door specialists for the best results.
What Is Garage Door Weatherstripping?
Garage door weatherstripping refers to the seals installed around each edge of your garage door to block out drafts, moisture, dust, and insects. It seals the interior of your garage off to any exterior elements you’d prefer to keep on the exterior. It includes:
- Garage door bottom seal
- Garage door side seal
- Top seals for the upper frame of the garage door
Together, these seals help maintain a more comfortable temperature inside both your garage and your home, and protect your belongings from the elements.
What Does a Garage Door Bottom Seal Do?
The garage door bottom seal is attached to the bottom edge of your door and compresses under the weight of the door when the door closes. Its main purposes include:
- Sealing out rain, snow, and debris
- Blocking out pests like mice, bugs, and snakes
- Reducing drafts and energy loss
- Softening the impact when the door closes
- Protecting the floor and door from damage
Over the course of their lifetime, seals can wear out, crack, or become misshapen, which makes reliable garage door bottom seal replacement highly important. With Good Day Garage Doors, you can trust that our garage door services are reliable!
The Benefits of Keeping Weatherstripping in Good Condition
Well-maintained weatherstripping around your garage door has a handful of great advantages:
- Improved energy efficiency: Keep warm air in during the winter and cool air in during the summer. You may even see a difference on your energy bill when switching to better weatherstripping in extreme climates.
- Better comfort: Eliminate drafts and dirt that make your garage less usable.
- Pest prevention: Stop bugs and rodents from entering your home.
- Protection against water damage: Avoid moisture buildup that can lead to mold or structural issues, or damage belongings stored in your garage.
- Extended door life: Reduce stress on the door and track system and extend the life of garage door components normally affected by the impact of the door meeting the ground when it closes.

What About the Garage Door Side Seal?

- Close gaps between the door and frame
- Block drafts and rain
- Reduce noise and vibrations
If you’re noticing light, air, or pests entering from the sides of your garage door, it may be time to replace your garage door side seal.
