If your garage feels like a wind tunnel in winter or your heating bill climbs every season, worn weather stripping and seals might be the culprit. A failing bottom seal or threshold doesn't just let in cold air.it invites moisture, pests, and rust. The good news: fixing this problem costs far less than replacing your entire door, and you'll feel the difference immediately.
Weather stripping is the rubber or foam material that runs along the edges of your garage door. It creates an airtight seal when the door closes. The bottom seal, or threshold, takes the most abuse because it bears weight and flexes every time you open and close the door. Over time, UV exposure, temperature swings, and regular wear compress and crack this material, creating gaps that let drafts slip through. See our guide on preparing your garage door for cold weather: essential tips.
In Sumner's climate, where winters dip below freezing and spring rains are heavy, a compromised seal costs money fast. Cold air escapes your conditioned garage. Moisture creeps in and accelerates rust on door panels and springs. Insects find their way inside. A simple rubber replacement prevents all three problems.
Look for these warning signs in your garage door:
Visible cracks, gaps, or peeling rubber around the door frame. A noticeable draft when the door is closed, especially at the bottom. Water pooling inside the garage during or after rain. Rust spots appearing on the lower door panels. The door feels harder to open than usual, or makes grinding sounds as it moves.
If you notice any of these, don't wait. Seals degrade faster once they start failing, and the longer you leave them, the more damage spreads to the door itself. Addressing this during Sumner's dry months (July through September) is smarter than waiting until winter arrives.
You can buy replacement weather stripping online for $30 to $80 and install it yourself. Sounds budget-friendly, right? Here's where most homeowners overspend: poor installation. If the seal doesn't sit flush, it won't seal. If you use the wrong material for your door type (sectional vs. roll-up), you'll buy twice. Professional installation ensures the right fit the first time.
Garage Door Sumner offers same-day estimates and can replace seals the same day in most cases. Professional service runs $150 to $300 depending on your door size and condition. That's not expensive insurance against a $2,000 door replacement five years early.

How long do garage door weather seals last? Most seals last 5 to 7 years in Sumner's climate. UV exposure, temperature swings, and moisture accelerate breakdown. Annual inspections catch failures early and prevent costly secondary damage to the door itself.
Can I replace just the bottom seal, or do I need all four sides? You can replace seals individually. However, if one side is failing, others likely are too. A technician can assess all four during a single visit and recommend the most cost-effective approach for your situation.
Will new seals help my heating bill? Yes. A compromised bottom seal lets warm air escape and cold air in. Replacement typically lowers garage heating costs by 10 to 15 percent, depending on how heavily you condition that space.
Is weather stripping replacement covered under warranty? Most manufacturer warranties don't cover seals because they're consumable parts. However, labor warranties may apply if you purchase seals from the door manufacturer or a certified installer.
