Water Damage in the Garage: Causes, Prevention, and Repair Tips

Your garage might not be the most glamorous area of your house, but it serves an important purpose in shielding your vehicle, hiding tools that are valuable, or could even be a workspace or laundry area. However, because garage spaces are usually not climate-controlled and are not properly sealed, they can be especially vulnerable to water intrusion. Unfortunately, if water is present, it could lead to big structural problems, mold development, and costly repairs.

In this blog, we will discuss how a garage is more vulnerable to water damage, common causes of water leakage issues in garage spaces, smart garage waterproofing tips, and recommendations for avoiding water damage in garages. We will even help you determine the best time to call in a water damage repair specialist.

Why Garage Water Damage Shouldn’t Be Ignored

Homeowners often ignore signs of moisture in the garage, assuming that just a little wetness won’t hurt anything. But over time, water damage can ruin drywall, rot wooden beams, rust tools and equipment, and promote the growth of mold and mildew—especially in the humid climate of Raleigh.

Water damage can even affect adjacent rooms in your house if you have an attached garage, which can affect insulation, wiring, and flooring. That’s why it’s vital to catch it early and utilize professional water damage repair as soon as water shows up where it shouldn’t.

Common Causes of Water Damage in Garage Spaces

Identifying the underlying causes of moisture buildup is essential to preventing it. Here are the most common ways water enters garage structures:

1. Poor Drainage or Grading

If the ground outside your garage slopes towards your house, then heavy rain can cause water to flow towards the garage. If there is no proper grading or working drainage system, that water may find its way under the garage door or foundation.

2. Cracks in the Foundation or Floor

Concrete walls and floors will crack over time as the soil settles and the earth expands or contracts with temperature changes. The cracks allow water to seep up from underneath, especially during storms, or when melted snow or ice is pooling in the area.

3. Broken or Missing Weather Stripping

Weather stripping on a garage door keeps it weatherproof. Without it, or simply old brittle weather stripping, rain can be allowed to enter the garage even when there are slight amounts of rain. Missing or broken weather stripping is the most common cause of water leakage into garages.

4. Roof Leaks or Faulty Gutters

If gutters are clogged or broken and causing water to spill over where it flows down the outside of the house, it will puddle at the base of the garage. If there are roof leaks anywhere above, that is another source for water to potentially run down towards the garage.

5. Plumbing Leaks or Laundry Overflow

A lot of garages have washing machines, utility sinks, or even water heaters sitting inside. Any one of them could break down and lead to internal leaks that you may or may not discover before damage occurs, particularly water damage, especially if you’re not home.

How to Prevent Water Damage in Garage Spaces

Now that you understand the potential failure points, let’s talk about taking proactive steps and improvements to prevent water damage in garages. Here are several suggestions:

  • Inspect the Garage Door Seals Regularly

Make a point to check the bottom seal and the weather stripping on the sides of the garage door at least twice a year. If you notice cracked or worn seals, replace them right away to prevent rain from blowing in, debris from collecting in your garage, and prevent other efficient downgrades.

  • Grade Your Driveway Away from the Garage

Ensure the slope of your driveway directs water away from the building. If your yard naturally slopes toward your home, consider hiring a contractor to adjust the grading or install a French drain.

  • Keep Gutters and Downspouts Clean

Your gutters should slope – remember they are to direct water in a downhill pathway, as I said, 5–10 feet away from your foundation and not let it pool around your house. Be sure to clean gutters at least twice a year, and check and empty debris whenever there’s a significant storm. Don’t forget to check if they have any sections that are clogged, leaking or have detached from the gutter, and they are not working to disperse water as it is designed.

  • Repair Foundation Cracks Promptly

If you have cracks that are small enough, use concrete sealant to fill the cracks as soon as you see them. If there are large cracks, contact a contractor to inspect and repair the damage so it won’t have the potential of attracting water that may take advantage of the vulnerability.

Smart Garage Waterproofing Tips

In addition to preventative actions, these garage waterproofing tips are worth trying to protect your garage throughout the year:

  • Seal your concrete floor with a high-quality epoxy or other waterproofing membrane to provide a barrier against moisture.
  • If your garage is susceptible to high humidity, consider installing a vapor barrier along the walls.
  • Use waterproof paint on your walls and ceilings so that water will roll off and still help reduce the risk of mold growth.
  • Do not store items directly on the floor. Raised shelving or plastic bins will protect them from flooding.
  • Dehumidifiers can help with humidity during warmer months in humid areas, such as Raleigh.
