A leaking garage door can allow rain and water to get into your home, causing damage. Learn about the types of repairs that can be done to fix the leak and protect your car and other belongings from moisture damage.

Three Reasons Your Garage Door Is Leaking When It Rains

Your garage door is a first line of defense against rain and wind from coming in and damaging your car, lawn equipment and the other items stored in the garage. A leak in the door could cause moisture problems with anything in the garage and could cause structural issues over time. A prompt garage door repair in San Luis Obispo can stop the garage door from leaking so that your belongings will not incur any further damage.

Broken Seal

Garage doors have a rubber seal around the door’s perimeter. The rubber seal makes contact with the door’s framing and stops moisture and wind from coming in. Years of exposure to heat and ultraviolet radiation from the sun can degrade the rubber, causing it to crack. A technician can replace the door seal to stop the leaking.

Cracks in the Panels

Cracks in the panels are another reason why your garage door could be leaking. This problem most often occurs in garage doors that are not insulated. Exposure to heat, wind and sunlight causes metals to expand and contract. Over time, this leads to small cracks. Wood garage doors that have not been sealed properly can also crack. A garage door with cracks may need to be replaced if there are a lot of cracks or the cracks are wide.

Rust

Rust is another reason why a garage door could leak. Rusted metal panels would allow rain to come in during a shower or storm. A rusted lock or garage door handle could also allow small amounts of moisture to penetrate inside. In a garage door that has metal window frames, rust could allow the frames to degrade. Moisture would then be able to condense around the glass and soak through the framing, causing damage to the rest of the door.
