Water Coming In Under Garage Door

Water leaking under your garage door can be a frustrating problem, especially during heavy rains or snowfalls. Not only can it damage your garage floor and belongings, but it can also create a safety hazard. Fortunately, there are several things you can do to identify and fix the source of the leak.

1. Inspect the Garage Door Seal

The most common cause of water leaking under a garage door is a damaged or worn-out seal. The seal is a strip of rubber or plastic that runs along the bottom of the door and helps to keep water out. Over time, the seal can become cracked, torn, or compressed, allowing water to seep underneath the door.

To inspect the seal, open the garage door and look for any gaps or tears. You can also try pouring water on the seal to see if it leaks. If you find any damage, you will need to replace the seal.

2. Check the Weatherstripping

Weatherstripping is another important part of the garage door that helps to keep water out. Weatherstripping is a thin strip of rubber or foam that is installed around the edges of the door to seal any gaps. Over time, weatherstripping can become worn or damaged, allowing water to leak in.

To inspect the weatherstripping, open the garage door and look for any gaps or tears. You can also try pressing on the weatherstripping to see if it is still flexible. If you find any damage, you will need to replace the weatherstripping.

3. Inspect the Threshold

The threshold is the metal track that the garage door rolls on. If the threshold is not properly sealed, water can seep underneath the door and into the garage.

To inspect the threshold, look for any gaps or cracks. You can also try pouring water on the threshold to see if it leaks. If you find any damage, you will need to seal the threshold.

4. Check the Door Frame

The door frame is the structure that the garage door is attached to. If the door frame is not properly sealed, water can seep into the garage around the edges of the door.

To inspect the door frame, look for any gaps or cracks. You can also try pouring water on the door frame to see if it leaks. If you find any damage, you will need to seal the door frame.

5. Check the Garage Floor

If you have checked all of the above and still have water leaking under your garage door, the problem may be with the garage floor. If the garage floor is not properly sloped, water can pool in the garage and eventually seep under the door.

To check the slope of the garage floor, place a level on the floor and measure the angle. The floor should be sloped away from the door at a rate of at least 1/4 inch per foot.

Conclusion

If you have water leaking under your garage door, it is important to identify and fix the source of the leak as soon as possible. By following the steps outlined above, you can find and repair the leak and keep your garage dry.
