Customer Service and Installation Expertise

A Garage Door Seal that actually fixes the gap under your garage door!

What the heck is a Snirt Stopper?

We have designed a garage door bottom seal and threshold seal that mounts to the inside face of the door instead of the bottom, this gives you the ability to adjust the seal up or down allowing you to match any unevenness (up to 2 inches) of shifting floors and garage doors.

Do you have a garage door gap? Does it let in light, rain, cold air, leaves and snow?

The Snirt Stopper garage door gap seal helps with little gaps, medium gaps and large gaps. The Snirt Stopper will fix any size garage door gap.

“I purchased a door seal for one of my worst gapped doors. I didn’t think it would work as I have always had snow blown into my shop. I put on the snirtstopper and there was a snowstorm that came and absolutely no snow blew in. This product really does work and I was so impressed I purchased 2 more seals. Thanks”
