10 Easy Steps on How to Stop Water Coming Under Garage Door

1. Check the Weather Stripping

The first step in preventing water from coming under your garage door is to check the weather stripping. The weatherstripping is a rubber or vinyl strip that runs along the bottom of the door and helps to keep out moisture. If it is cracked, torn, or missing, it may not work correctly and should be replaced. Additionally, ensure that the weather stripping is correctly sealed around the edges of the door frame.

2. Install a Threshold Seal

Installing a threshold seal is another way to prevent water from coming under your garage door. A threshold seal is a rubber or vinyl strip that runs along the bottom of the door and creates an extra barrier against moisture. It can also help to insulate your garage by blocking cold air from entering through gaps between the floor and door.

3. Clean Out Gutters

Finally, ensure that your gutters are clean and free of debris so they can properly drain water away from your home.

Clogged gutters can cause water to back up and spill onto your driveway, seeping underneath your garage door and into your house. Cleaning out your gutters regularly will help ensure they function correctly and keep water away from your house.

4. Use a Garage Door Seal

If you continue to experience water seepage even after checking the weather stripping, installing a threshold seal, and cleaning out the gutters, consider using a garage door seal. This is a seal that runs along the bottom of the door, often complementing the weather stripping and threshold seal for enhanced protection.

 Installing a Threshold Seal

It helps to create a watertight barrier between the door and the ground, preventing water from seeping through. Installing a garage door seal requires careful measurement of the door and the ground, but once in place, it can be a highly effective way to stop water from entering under your garage door.

5. Apply a Water Repellent

A water repellent can be an effective solution for preventing water from coming under your garage door. This product type is designed to create a barrier that water cannot penetrate. It can be applied to both the garage door and the floor.

Be sure to follow the application instructions on the packaging closely, as methods can differ between brands. Once applied, the water repellent should help keep the area under your garage door dry and moisture-free.

6. Install a Drainage System

In case of severe water issues, installing a drainage system might be a viable solution to stop water from coming under your garage door. A trench or French drain can be installed in front of the garage door, allowing water to be redirected away from the garage entrance.

This can prevent water from pooling and potentially seeping underneath your garage door. Note that this method may require professional installation and can vary in cost depending on the system’s complexity.

7. Elevate the Garage Door

Another effective method is to elevate the garage door. This might involve adjusting the door’s side tracks or even installing a new door track system. Promoting the garage door reduces the chances of water seeping under the door, particularly in areas prone to heavy rainfall or flooding.

It’s essential to note that this method may require professional assistance due to the complexity of the task. Additionally, the cost will depend on the specific requirements of your garage.

8. Use Sandbags or Flood Barriers

If you live in an area prone to heavy rains or flooding, sandbags or flood barriers can be an effective temporary solution to stop water from coming under the garage door. These barriers are designed to absorb water and expand, forming an obstacle that prevents water from passing through.

 Flood Barriers Can Be an Effective

Simply place them at the base of your garage door whenever you anticipate heavy rainfall. Remember that this is a temporary fix, and you should seek a more permanent solution for long-term protection.

9. Resurface or Slope the Driveway

If water is running down your driveway and seeping under your garage door, it might be due to the slope of your driveway. One effective solution could be to resurface or slope your driveway so that water is directed away from the garage.

By creating a gentle slope away from the garage door, water will naturally flow towards the street or a drainage area rather than your garage. This is a more complex task that may require the help of a professional, but it can be a long-term solution to preventing water from entering your garage.

10. Regular Maintenance

Consistent, regular maintenance is the final step to stop water from coming under your garage door. This involves routinely checking the weather stripping, threshold seal, and garage door seal for damage or wear and tear.

Checking the Weather Stripping

Clean your gutters and drainage system regularly to ensure they’re free of debris and functioning properly. Also, keep an eye on the slope of your driveway and the state of your sandbags or flood barriers if used. Regular maintenance will help identify potential issues before they become significant, ensuring your garage stays dry and safe from water damage.

Following these tips, you can effectively stop water from coming under your garage door and protect your home. Remember to regularly check for any signs of moisture or damage and address them promptly to prevent further issues.

5 Additional Tips and Tricks

  1. Regular Inspections: Regularly inspect your garage door and its surrounding area for signs of damage or wear. Cracks, dents, or warping can indicate that water is seeping in, which should be addressed immediately.
  2. Sealant Reapplication: Over time, various seals and sealants around your garage door may wear out and lose effectiveness. Regularly reapply these products to maintain a watertight barrier between the garage door and the ground.
  3. Professional Assistance: While many solutions can be implemented independently, seek professional help when necessary. This is especially relevant when implementing solutions like installing a new drainage system or adjusting the garage door’s elevation.
  4. Weather Considerations: Pay particular attention to weather forecasts. If heavy rainfall or a storm is expected, take preventive measures such as installing temporary flood barriers or sandbags.
  5. Home Insurance: Lastly, you may consult with your home insurance provider about coverage for water damage. While prevention is paramount, it’s wise to be prepared for potential repair costs.

With these tips and tricks, you can effectively stop water from coming under your garage door and keep your home dry and safe.

5 Things You Should Avoid

  1. Ignoring Early Signs: Don’t ignore early signs of water seepage like damp floors, rusting, or mold growth. These are often indicators of a bigger issue and should be addressed promptly to avoid structural damage.
  2. Delaying Maintenance: Refrain from regular maintenance of your garage door and the surrounding areas can exacerbate water seepage issues. Regularly inspect seals, drainage systems, and the slope of your driveway to ensure they’re functioning effectively.
  3. Choosing Quick Fixes Over Permanent Solutions: While quick fixes like sandbags or flood barriers can help temporarily, it’s important not to rely on them for long-term water leakage prevention. Consider investing in more permanent solutions like a drainage system or a garage door seal.
  4. Improper Installation: Only install water prevention measures like seals or drainage systems with proper knowledge or tools. A proper installation could lead to effective water management and possible damage.
  5. Overlooking Weather Patterns: Pay attention to local weather patterns when deciding preventive measures. If your area experiences heavy rainfall or flooding, your preventive measures should reflect this. Ignoring weather patterns could leave your garage vulnerable to water damage.
Experiences Heavy Rainfall

By avoiding these common mistakes, you can effectively stop water from coming under your garage door and keep your home protected.
