Water Under Your Garage Door Might Not Be a Seal Problem

A lot of homeowners assume the worst when they find water inside their garage after a rainstorm. The instinct is usually to replace the bottom seal and call it a day. Sometimes that works. But a lot of the time, the seal isn't the problem at all - and replacing it won't fix anything.

Here's what's actually happening in many of these situations. The concrete apron or driveway outside the garage has a slope that sends water directly toward the opening instead of away from it. When rain hits hard enough, that water travels right under the door no matter how good the seal is. The seal can only do so much against hydrostatic pressure and poor drainage grades.

This is one of those things that's easy to miss if you don't know what to look for. We've seen homeowners go through two or three seals trying to solve a drainage problem - spending money and time on fixes that never had a chance of working. Getting eyes on the right part of the issue is what actually moves the needle.

That's a big part of what we do. We look at the full picture - the door, the tracks, the seal, and the concrete at the threshold - to figure out where the real problem is. Proper garage door track alignment also plays into this, since a door that doesn't sit flush at the bottom can leave gaps that make water intrusion worse. It's all connected.

If you've got water showing up inside your garage and you're not sure why, it's worth getting a proper diagnosis before spending money on parts that won't solve it. Knowing the actual cause is always step one.
