Weather Seal Repair & Replacement

Your weather seal is the flexible rubber or vinyl strip that runs along the bottom of your garage door (and sometimes around the sides and top), and it's the unsung hero keeping rain, snow, dust, leaves, and critters out of your garage. It's also one of the cheapest, hardest-working parts on the whole door, which is exactly why folks tend to ignore it until water is pooling on the floor or a draft is running up their heating bill. The good news: a worn seal is one of the simplest things to swap out, and catching it early saves you from water damage, pests, and wasted energy.

Warning signs

Signs your weather seal need attention

Daylight under the closed door

Stand inside with the door shut and look along the bottom. If you can see a sliver of daylight, that's the same gap letting in rain, cold air, and bugs. A good seal should sit flush against the floor with no visible light getting through.

Water or snow sneaking in

Puddles along the bottom of the door after a storm, or snow drifting in at the corners, mean the seal isn't making contact anymore. Left alone, that moisture can warp the bottom panel, rust hardware, and ruin anything you store on the floor.

Cracked, brittle, or torn rubber

Run your hand along the seal. If it's stiff, crumbling, split, or flaking off in pieces, the rubber has dried out from years of sun and temperature swings. Once it loses its flexibility it can't form a tight seal anymore, no matter how nicely the door closes.

Drafts and a colder garage

If your garage suddenly feels drafty or your attached rooms are harder to keep warm, a failed seal is a common culprit. You may even notice a bump in your heating or cooling bill as conditioned air leaks out around the door.

Bugs, leaves, and critters getting in

Finding leaves blown in, spiders setting up shop, or mice slipping under the door usually points to a gap in the bottom seal. Rodents especially love an opening the seal is supposed to close off.

The seal is flattened or pulling loose

A bottom seal that's been squashed flat, or one that's sagging and hanging out of its retainer track, has lost its shape and won't spring back to fill the gap. If it's flapping or dragging when the door moves, it's past due for replacement.

Lifespan

How long do weather seal last?

Typically 5 to 10 years, though harsh sun, freezing winters, and heavy use can wear it out sooner
