Common Causes of Water Leakage Under Garage Doors
Water leakage under garage doors is a common issue homeowners and businesses face. It can lead to various problems, including damage to the garage’s structure, mold growth, and even damage to stored items. Understanding the causes of water leakage and how to address them can save you time, money, and hassle. This blog will explore the common causes of water leakage under garage doors and provide practical solutions to prevent it.
Poor Door Seals
Poor door seals are among the most common causes of water leakage under garage doors. Over time, the weather stripping that seals the bottom of your garage door can wear out or become damaged. When this happens, it creates gaps that allow water to seep into the garage.
Solution: Regularly inspect the weather stripping for signs of wear and tear. Replace it if it appears brittle, cracked, or damaged. High-quality weather stripping can be purchased from most home improvement stores, and replacing it is a straightforward task that can significantly reduce water leakage.

Improper Door Alignment
Garage doors that are not properly aligned can also cause water to leak into the garage. If the door doesn’t sit flush with the ground when closed, it can leave gaps through which water can enter.
Solution: Check the alignment of your garage door by closing it and inspecting the bottom edge. You may need to adjust the door’s alignment if you notice gaps or uneven spacing. Adjusting the garage door tracks or the door itself can often do this. If you’re unsure how to do this, consider contacting a professional for Garage Door Repair to ensure it’s done correctly.
Cracks in the Garage Floor
Cracks in the garage floor can allow water to seep up from the ground below, especially during heavy rainfall or high water tables. These cracks can develop over time due to the natural settling of the ground or due to heavy loads placed on the garage floor.
Solution: Inspect your garage floor for cracks and seal them using a high-quality concrete sealant. For larger cracks or significant water issues, it may be necessary to have a professional assess and repair the damage. Regular maintenance and prompt attention to cracks can prevent more severe water damage in the future.
Clogged or Ineffective Drainage Systems
Garages, especially those on a slope or areas prone to heavy rainfall, rely on effective drainage systems to divert water from the building. If the drainage systems, such as gutters and downspouts, are clogged or ineffective, water can pool around the garage and eventually seep inside.
Solution: Regularly clean and maintain your gutters and downspouts to ensure they are debris-free. Additionally, consider installing a French drain or other drainage solutions around your garage to help direct water away from the building. Keeping the surrounding area clear of leaves and debris can also help improve drainage efficiency.
Sloping Driveway
A driveway that slopes toward the garage can funnel water directly toward the garage door, increasing the risk of water leakage. This is particularly problematic during heavy rains or snowmelt.
Solution: If your driveway slopes toward the garage, consider installing a trench drain at the bottom to catch and redirect water away from the garage. Alternatively, you can regrade the driveway to slope away from the garage, though this is a more extensive and costly solution. A slight elevation to the garage door area can also help reduce water ingress.
Inadequate Garage Door Design
Certain garage door designs are more prone to water leakage than others. For example, older wooden doors may not provide as tight of a seal as modern metal or insulated doors. Additionally, doors with windows or other design features may have more potential leakage points.
Solution: Consider upgrading to a more modern, energy-efficient garage door with better sealing properties. Precision Door of Southern California offers a variety of Energy-Efficient Garage Doors that can help reduce water leakage while improving your garage’s overall efficiency.
Weather Conditions
Certain weather conditions, such as heavy rain, snowmelt, or high humidity, can increase the likelihood of water leakage. While you can’t control the weather, you can take steps to mitigate its impact on your garage.
Solution: Be proactive in preparing your garage for adverse weather conditions. Ensure that all preventive measures, such as sealing cracks, door seals, and proper drainage, are in place before severe weather hits. You can also invest in additional weatherproofing measures, such as garage door thresholds or barriers, to protect against water ingress.

Gaps and Spaces Around the Garage Door
Over time, gaps and spaces can develop around the edges of the garage door due to the settling of the foundation or wear and tear. These gaps can allow water to enter, especially during heavy rain or when the landscape directs water toward the garage.
Solution: Regularly inspect the perimeter of your garage door for gaps and spaces. Use caulk or expandable foam to seal any small gaps you find. For larger gaps, you may need to install additional weather stripping or have a professional adjust the door and frame to ensure a snug fit. Regular maintenance and prompt attention to developing gaps can help keep your garage dry.
High Water Table and Groundwater Pressure
In areas with a high water table, groundwater pressure can force water through the ground and into the garage. This is more common in regions with heavy rainfall or poor drainage.
Solution: If you suspect groundwater pressure is causing water leakage in your garage, consider installing a sump pump to help manage and redirect water away from it. Waterproofing the garage floor and walls with a sealant can also protect against water ingress. Consulting with a professional to assess and address groundwater issues is often the best action.
Preventive Measures to Avoid Water Leakage
Regular maintenance and proactive measures are key to preventing water leakage under your garage door. Here are some tips to keep your garage dry:
- Regular Inspections: Inspect your garage door, seals, and floor for any signs of wear, damage, or gaps. Address any issues promptly.
- Upgrade Weather Stripping: Replace old or damaged weather stripping to ensure a tight seal at the bottom of the garage door.
- Maintain Drainage Systems: To ensure effective drainage, keep gutters, downspouts, and other drainage systems clear of debris.
- Install Drainage Solutions: Consider installing trench drains, French drains, or other drainage solutions to divert water from the garage.
- Seal Cracks: Regularly inspect and seal any cracks in the garage floor and walls to prevent water seepage.
- Improve Door Alignment: Ensure your garage door is properly aligned and sits flush with the ground when closed.
- Choose the Right Door: Opt for modern, energy-efficient garage doors with better sealing properties to reduce the risk of water leakage.
By understanding the common causes of water leakage under garage doors and implementing these preventive measures, you can protect your garage from water damage and maintain a dry, functional space.
