Why Does My Garage Door Area Always Have Water Intrusion?

The most frequent cause is a garage floor that slopes toward the house, not away from it. Rain runs down the driveway and collects at the door threshold. Over time, the concrete may settle, creating a low spot where water stands.

Another cause is a worn or misaligned bottom seal on the garage door. If the rubber gasket is cracked or flattened, water seeps through the gap. Also, the concrete apron outside can crack, letting water travel under the slab and into the garage.

• Check the slope of the driveway and garage floor
• Inspect the bottom seal for gaps or damage
• Look for cracks in the concrete apron
• Clear debris from the drainage channel near the door
• Test with a hose to see where water enters

Start by cleaning the area around the door. Remove leaves, dirt, and any debris that blocks water flow. Then, adjust the garage door's bottom seal if it is loose. You can also apply a concrete sealant to minor cracks to reduce seepage.

Check the grading of the ground next to the garage. The soil should slope away from the foundation for at least six feet. If it does not, add fill dirt to create a proper slope. This simple step often solves the problem.

Regular maintenance is key to keeping water out. Inspect the garage door seal every few months and replace it when it shows wear. Keep gutters and downspouts clear, and extend downspouts at least three feet away from the foundation.

Consider installing a threshold seal or a small drain channel at the base of the door. These can redirect water before it enters. If you live in St. Petersburg, remember that rainy season brings heavy downpours, so check your garage area before storms.
