Installation: Garage Door Weatherstripping

Replacing damaged weatherstripping around the door will help keep dirt, debris, and insects and rodents from entering the garage. Weatherstripping, when combined with an insulated garage door, also helps to reduce drafts as well as block energy loss. About once a month, inspect garage door weatherstripping for cracks or damage, and replace it. You can self-install new materials or hire someone to do the job for you.

Here’s what you need to know about replacing garage door weatherstripping:

Choosing the Right Materials
Before heading to your local home improvement store for materials, it’s important to measure the width, height and thickness of your garage door. You’ll need these measurements to purchase both the right products and amount of material. Increasing the energy efficiency of your garage includes applying two materials: Threshold seals and weatherstripping. There are several different types available as well.

According to the U.S. Department of Energy, the best weatherstripping should withstand the climate, including temperature changes for your specific location as well as its application. Vinyl or rubber is usually the best choice for garage doors because it holds up well and resists moisture. Metal bottom seals are another option to consider. These materials are available with self-stick tape or tacks. Others require exterior caulk or glue.

Applying Garage Door Weatherstripping
Remove the old material. Then clean the door, where the product will be replaced, and allow to dry. Ensuring a clean and dry surface will help with adhesion – especially if using tape or caulk. After measuring a second time, cut the seal to length with a razor knife, then thread the edges into the weather seal track. Be patient; a lot of pushing and pulling may be required! Repeat to the next panel until complete.

Now you can move on to the threshold seal. After thoroughly cleaning the concrete with a degreasing agent and water, and allowing to dry, roll the threshold into place with the hump on the inside of the garage door and cut to the width of the opening. Carefully follow all manufacturer instructions for a snug fit. Remember, threshold seals have the job of keeping water, debris and unwelcome guests out of the garage so proper fit is important.
