Understanding the Issue

Before we can effectively address the issue of water coming under the garage door, it’s important to understand why it happens in the first place. There are several factors that can contribute to this problem:

1. Poor garage door alignment: If your garage door is not properly aligned, it can create gaps and spaces where water can easily seep through. Over time, the alignment of the door can shift due to everyday use, temperature changes, or wear and tear.
2. Worn-out or damaged weatherstripping: Weatherstripping is a strip of material that is attached to the bottom of the garage door to create a seal with the ground. If the weatherstripping is old, cracked, or damaged, it can no longer effectively stop water from entering the garage.
3. Lack of a threshold seal: A threshold seal is a rubber strip that is installed at the bottom of the garage door, creating a barrier against water, pests, and debris. If your garage door does not have a threshold seal or if the seal is damaged, it can allow water to flow underneath.
4. Cracks and gaps in the garage floor: If your garage floor has cracks or gaps, water can easily find its way inside. This can be particularly problematic during heavy rainfall or when there is poor drainage around the garage.
5. Poor or insufficient garage drainage: If your garage does not have proper drainage systems in place, water can accumulate and find its way under the door. This can happen if the garage is below ground level or if the surrounding landscape does not allow for proper water runoff.

By understanding these potential causes, you can better assess the specific issues contributing to water entering your garage. This knowledge will help you identify the most appropriate solutions to keep your garage dry and protected.

Identifying Possible Causes

When it comes to water coming under the garage door, there can be several causes at play. Identifying these causes is essential in order to implement the right solutions. Here are some possible causes to consider:
