How To Stop Water From Getting Into Your Garage

Water intrusion into a garage can lead to a multitude of problems, including damage to stored items, structural weakening of the building, mold and mildew growth, and even electrical hazards. Addressing the sources of water ingress promptly and effectively is vital for maintaining the integrity and usability of the garage space. This article outlines several methods for identifying and mitigating common entry points for water, thereby protecting the garage from potential water damage.

Addressing the Garage Door Seal

The garage door is frequently the primary point of entry for water. The seal at the bottom of the door, designed to create a tight barrier against the floor, is prone to wear and tear over time. Cracks, gaps, or deterioration in the seal allow rainwater to flow directly into the garage, especially during heavy storms. A thorough inspection of the bottom seal is the first step in preventing this issue.

Examine the seal closely for any signs of damage, such as tears, cracks, dry rot, or areas where the rubber has become brittle. If any of these issues are detected, the seal should be replaced. Replacement bottom seals are typically available at home improvement stores and come in various materials, including rubber, vinyl, and foam. The selection should be based on the door type and the severity of the weather conditions in the area.

The installation process typically involves removing the old seal, cleaning the track beneath the door, and sliding in the new seal. Some seals are attached with screws, requiring the old screws to be removed and the new seal to be secured with replacement screws. Ensuring the new seal is properly aligned and tightly fitted against the floor is paramount for optimal performance. In some instances, the floor beneath the door may not be level. In these cases, a thicker seal or a custom-made seal might be necessary to bridge the gap effectively.

Beyond the bottom seal, the side and top seals of the garage door also warrant attention. These seals prevent water from seeping in around the edges of the door. Check these seals for similar signs of wear and replace them as needed. The side and top seals are typically attached using nails, screws, or adhesive. Carefully remove the old seals, clean the surface, and install the new seals, ensuring a tight fit against the door frame.

In addition to replacing the seals, consider the door's overall condition. An old or damaged garage door may not close properly, creating gaps that allow water to enter. Repairing or replacing an aging garage door can significantly improve its ability to keep water out.

Managing Drainage Around the Garage

Proper drainage around the garage is vital for directing water away from the foundation and preventing it from pooling near the entrance. If the ground slopes towards the garage, rainwater will naturally flow towards the door, increasing the likelihood of water intrusion. Modifying the landscape to improve drainage can be a highly effective preventative measure.

One option is to create a swale, a shallow ditch or trench, along the perimeter of the garage. The swale should slope away from the building, channeling water towards a designated drainage area, such as a storm drain or a lower-lying part of the yard. The swale can be lined with gravel or stones to prevent erosion. Vegetation can also be planted within the swale to help absorb water and stabilize the soil.

Extending downspouts away from the garage is another important step. Downspouts that release water close to the foundation can contribute to water buildup and eventual seepage into the garage. Install gutter extensions to carry the water further away from the building. These extensions can be made of plastic, metal, or flexible tubing. Ensure the extensions are securely attached and direct the water to a suitable drainage area.

If the area around the garage is paved, inspect the pavement for cracks or depressions where water can collect. Fill any cracks with concrete crack filler and level out any low spots with a concrete patching compound. This will help to prevent water from pooling near the garage door and seeping underneath.

French drains offer a more comprehensive drainage solution. These consist of perforated pipes buried in a trench filled with gravel. The pipes collect water from the surrounding soil and carry it away to a designated drainage point. Installing a French drain along the foundation of the garage can be particularly effective in areas with persistent drainage problems.

Sealing Cracks and Foundation Issues

Cracks in the garage floor, walls, or foundation can provide pathways for water to enter. Even hairline cracks can allow water to seep through over time, especially during periods of prolonged rain or snowmelt. Addressing these cracks promptly is essential for preventing further water damage.

Begin by thoroughly inspecting the garage for any cracks or gaps. Pay close attention to the floor, walls, and foundation, as well as areas around windows and door frames. Use a flashlight to illuminate dark corners and hard-to-reach areas. Mark any cracks you find with a marker or tape to ensure they are properly addressed.

For small cracks in the concrete floor or walls, use a concrete crack filler or sealant. These products are typically available in tubes or cartridges and can be applied using a caulking gun. Clean the crack thoroughly before applying the filler, removing any loose debris or dirt. Apply the filler evenly and smoothly, ensuring it fills the entire crack. Allow the filler to dry completely according to the manufacturer's instructions.

Larger cracks, particularly those in the foundation, may require more extensive repairs. Consider consulting with a professional contractor for these types of repairs. A contractor can assess the severity of the crack and recommend the appropriate repair method, such as epoxy injection or concrete patching. Epoxy injection involves injecting a high-strength epoxy resin into the crack to seal it and restore its structural integrity. Concrete patching involves removing the damaged concrete and replacing it with new concrete.

If water is seeping in through the joint between the garage floor and the walls, consider applying a waterproof sealant to this area. Clean the joint thoroughly and apply a bead of sealant along the entire length of the joint. Smooth the sealant with a finger or a tool to create a watertight barrier. Regularly inspect the sealant for signs of wear and reapply as needed.

In some cases, the foundation may be porous, allowing water to seep through the concrete itself. Applying a waterproof coating to the exterior of the foundation can help prevent this type of water intrusion. These coatings are typically applied using a brush or roller and create a barrier that prevents water from penetrating the concrete.

Additionally, ensure proper ventilation within the garage. Moisture buildup can exacerbate the effects of water intrusion, leading to mold growth and further damage. Install vents or use a dehumidifier to help circulate air and remove excess moisture from the garage.
