If you've ever felt a cold draft sneaking under your garage door on a winter morning, you know the culprit: failed weather stripping and seals. A deteriorated bottom seal or side gasket doesn't just waste energy.it invites moisture, pests, and structural damage into your garage and home. The good news? Replacing them is affordable, fast, and something we handle same-day here in Bennington.
New Hampshire winters are brutal. Temperature swings from freezing nights to mild afternoons cause rubber and foam seals to crack, harden, and shrink. After 5,7 years of seasonal stress, most weather stripping loses its flexibility. UV exposure from summer sun speeds up that breakdown.
But it's not just winter damage. Moisture from spring thaws, salt spray near roads, and humidity in summer all degrade seals faster than you'd expect. I've seen garage doors with gaps so large you could see daylight around the entire frame.and homeowners had no idea how much that was costing them in heat loss.
The threshold, or bottom seal, takes the worst beating. Every time your door opens and closes, that rubber strip flexes. Dirt accumulates. Ice builds up. Eventually, it cracks and peels away entirely.
Watch for these warning signs:
- Visible cracks or chunks missing from the rubber bottom seal or side gaskets - Daylight visible around the door frame when closed - Cold drafts or noticeable temperature drops in the garage - Pest or insect activity.rodents and bugs exploit tiny gaps - Water pooling on the garage floor after rain or snow melt - Increased heating or cooling costs with no obvious cause
If you notice even one of these, don't wait. A small gap becomes a big problem once winter arrives. And if your door is already struggling with cold weather, check our post on why garage door springs break in Bennington winters.damaged seals can put extra strain on the entire system.
Not all seals are created equal. Understanding the options helps you make an informed choice.
Bottom Seal (Threshold Gasket) This is the rubber strip running along the base of your door. It flexes with each cycle and bears the most impact. Vinyl and EPDM rubber are common materials; EPDM lasts longer but costs slightly more. Replacement typically runs $75,$200 depending on your door's width.
Side Gaskets These foam or rubber strips line the vertical tracks. They prevent drafts and keep debris out. Replacement is usually $50,$100 per side.
Top Seal Less critical than the bottom, but equally effective at blocking draft. Often included in a full seal kit.
Weatherstripping Tape For smaller gaps or temporary fixes, adhesive-backed foam tape works in a pinch. It's cheap ($10,$30) but wears faster than structural seals.

Many homeowners ask if this is something they can DIY. Technically, yes.bottom seals are the easiest. But if you install them wrong, they won't seal properly and drafts will persist.
