Ways to Waterproof Your Garage & Garage Door

January 8, 2024

Is water and debris getting into your garage? This can often be the result of your garage door. Garage doors come with a bottom seal to keep out the dirt and water, but they do wear out from time and use. In some extreme cases, the concrete floor or driveway could create larger gaps under the door that could result in the standard seals not working properly. Additionally, older garage doors or doors installed on new homes may not be well insulated or may not have a full perimeter weatherstripping to seal out the harsh elements.

Here are a few ways you can waterproof your garage and garage door:

  1. Adding Rubber Astragal and Weatherstripping
  2. Seal Cracks & Gaps
  3. Add Protective Coating to Garage Floor
  4. Regular Maintenance

Adding Rubber Astragal and Weatherstripping

First off, what is weatherstripping? Weatherstripping is the overall process of sealing any openings to keep out weather, increase interior comfort level, lower utility bills, and reduce noise.

There are many benefits to weatherstripping your garage door. It protects the interior of your garage from flooding as well as provides overall insulation to your home. During the summer months, the cool air will stay in, and during the winter months, weatherstripping keeps the snow and rain out.

Our rubber astragal lines the bottom of the door to help seal out those elements as well as rodents. While the weatherstripping provides protection around the perimeter of the garage door. 

Additionally, the bottom of the garage door will not scrape against the concrete or pavement with weatherstripping. Ultimately helping prevent premature wear and tear of both the door and the floor.

Seal Cracks & Gaps

For minor cracks and gaps, you can use a caulking gun with water-proofing caulk or sealant. Sealing these gaps will help prevent water from seeping up from the ground.

Add Protective Coating to Garage Floor

Concrete slab foundations are durable, but water can still seep in from time to time causing problems like cracks and splitting.

A potential solution is to apply a barrier using a protective coating, such as epoxy or another waterproofing sealant made for concrete.

Be sure to apply to clean concrete and apply a second coat if required.

Regular Maintenance

Yearly maintenance for your garage door is not only important to make sure your garage door, tracks, springs, and opener are working, but to also look at those weatherstrips and help you make sure they get replaced and are in the best shape to keep your garage dry.
