A customer called last Tuesday asking why her heating bill spiked in January. Turns out, cold air was pouring in around her garage door's bottom seal. She'd never replaced the weather stripping since moving in eight years ago. One afternoon visit later, we installed a new threshold and bottom seal, and her draft problem was solved. That's the kind of straightforward fix that saves money and keeps your home comfortable.
Weather stripping and seals on your garage door aren't glamorous, but they're critical. Over time, rubber deteriorates, gaps form, and conditioned air escapes. If you're noticing drafts near your garage or seeing higher utility costs, your seals probably need attention.
Garage door seals endure constant temperature swings, UV exposure, and friction. In Farmington's climate, freeze-thaw cycles are especially brutal on rubber. When temperatures drop below freezing at night and warm up during the day, the material expands and contracts. This stress causes cracking and brittleness.
Most rubber seals last 5 to 7 years before they start to degrade visibly. If you've had the same seals for a decade, they're almost certainly leaking. The bottom seal takes the most punishment because it sits closest to the ground and bears the door's weight.
Look for these warning signs around your garage door:
- Visible light streaming in around the edges or threshold, Daylight visible under the door when it's closed, Drafts or cold spots near the garage, Water pooling inside after rain or snow, Higher heating and cooling bills without explanation
If you see any of these, don't wait. A failing seal affects more than comfort. It also compromises the security of your garage and allows pests to enter.

Ignoring worn seals creates a domino effect. Cold air leaks strain your HVAC system, driving up energy costs by 10 to 15 percent if your garage is attached. That's real money over a heating season. Additionally, moisture seeps in and can damage stored items, vehicles, and even the structural integrity of the door itself.
The good news: replacing weather stripping and seals is affordable. Our estimate typically ranges from $150 to $400 depending on which seals need replacement and the condition of the door frame. Compare that to an extra $500 to $1000 per winter season in wasted heating, and the math is obvious.
We've helped hundreds of Farmington homeowners and those in nearby towns like Hollis make this upgrade. It's one of the smartest maintenance investments you can make. For details on our full maintenance approach, see our garage door maintenance guide for honest advice.
Your garage door has three main sealing areas. The bottom seal (or threshold) is the most critical. This rubber strip compresses when the door closes and creates an airtight barrier. The side seals run along the vertical tracks and prevent air from leaking through the gaps. The top seal sits above the door and stops drafts from entering from above.
When we come out for an estimate, we inspect all three areas. Sometimes only the bottom seal needs replacement. Other times, especially in older homes, all three should be updated at once. We'll walk you through what's needed and give you honest pricing.
We understand that cold air coming into your garage is annoying, especially when winter is still in full swing. That's why we offer same-day appointments for seal replacements whenever possible. Most jobs take under an hour, and you'll notice the difference immediately.

How often should I replace garage door weather stripping? Most weather stripping lasts 5 to 7 years in New England climates. If you notice visible cracks, gaps, or daylight around the door, replacement is overdue. We can assess wear during a maintenance visit.
Can I replace seals myself? It's possible, but tricky. The bottom seal requires careful removal and proper alignment to compress correctly. Incorrect installation leaves gaps that defeat the purpose. We recommend professional installation for best results.
What's the difference between a bottom seal and a threshold? A bottom seal is the rubber strip attached to the door itself. A threshold is the metal or plastic channel mounted to the garage floor. Often both need replacement for a complete seal.
Will new seals reduce my heating bill? Yes, significantly. Homeowners typically save 10 to 15 percent on heating costs when seals are replaced, especially if their garage is attached to the house.
How long does a seal replacement take? Most jobs take 30 to 60 minutes. We schedule same-day appointments whenever possible so you're not waiting around.
