Garage Door Weather Seal

Garage Door Weather Seal

Garage Door Weatherstrip Facts

If you have an older garage door, chances are that it doesn’t seal very well. If the garage door isn’t properly sealed, cold air will blow in and warm air will escape from the garage. Garage door weatherstrip is designed to protect the interior of the garage from weather and improve energy efficiency.

However, over time, this weather seal can become dry, brittle, and prone to cracking, or may fall out entirely due to wear and tear. When this happens, it is important to replace the weather seal as soon as possible to maintain the benefits it provides. Replacing damaged weatherstrip is a low-cost repair that can have a significant impact in the long run by helping to protect the garage from weather and reduce energy costs.

How it Works: Garage Door Weatherstrip

Garage Door Weatherstrip - Garage Door Bottom Seal

Weatherstrip or weather seal is a rubber seal that goes between the garage door and concrete floor to help keep cold air out in the winter and warm air in the summer. It also prevents drafts, which can lead to energy loss and higher heating bills, as well as water and dust infiltration.

Depending on your location, you may need just a single piece of garage door weather seal to improve energy efficiency drastically. If you’re not sure what kind of weatherstrip your garage requires, take a look at our garage door bottom seal page. Garage door bottom seals are long pieces of rubber or vinyl that are attached to the bottom edge of a garage door using a steel, PVC, or aluminum retainer. When the door is closed, these seals compress against the floor to create a tight seal that helps to keep out water, dirt, debris, extreme temperatures, and pests. They are typically installed within a retainer on most garage doors, but may be nailed directly to the lower edge of wooden doors.

How to Install a Garage Door Bottom Weatherstrip

The first step to installing a new garage door bottom weatherstrip is to remove the old weatherstrip. Start by opening your garage door and removing any debris or dirt that may be hanging onto it.

To replace the bottom seal on a garage door, start by raising the door to a comfortable height and measuring the length of the door, adding an extra inch on each side to allow for adjustments.

Next, measure the width of the bottom of the door and the existing gasket, if possible. To remove the old gasket, use a screwdriver to back out any screws, taking care not to damage the steel garage door.

To install the new gasket, slide it into the existing bracket sleeve and attach it to the bottom of the door using screws, trying to use the same holes as the old gasket to avoid damaging the insulation. Once the gasket is in place, trim any excess length with a utility knife or hand saw, being careful not to damage the surface of the door.

Finally, test the seal by lowering the door and checking for a continuous seal along the bottom. It is important to make sure that the new gasket is compatible with the specific model of garage door and to release the door from the opener before attempting to raise it by hand.

Installing new garage door weatherstrip is a quick, easy and inexpensive way to keep your garage warm in the winter and cool in the summer.

It is important to regularly replace the bottom weather seal on a garage door in order to maintain the door and extend its lifespan.
