Weather Stripping & Seals in Curlew: Stop Drafts Before Winter
2026-05-23 7 min read A2Z Garage Doors
A customer called last Tuesday morning. Her garage was 32 degrees while her house sat at 68. She'd assumed it was just "how garages are," but the culprit was a deteriorated bottom seal that had cracked and peeled away months earlier. Weather stripping and seals in Curlew are your garage's first defense against drafts, heat loss, and unwanted pests. Without them, you're bleeding money every single month.
What Weather Stripping & Seals Actually Do
Your garage door isn't solid rubber. It's aluminum panels, glass, or composite material with gaps all around the perimeter. Weather stripping fills those gaps. The bottom seal (also called a threshold seal) is the hardest working piece. It takes the brunt of temperature swings, moisture, and ground contact. Over time, UV rays, freeze-thaw cycles, and simple wear crack the rubber and make it brittle.
When seals fail, three problems cascade. First, your furnace works overtime heating wasted space. Second, moisture sneaks in and promotes rust on springs and hardware. Third, insects and rodents find their way inside. I've seen spiders, wasps, and worse colonizing the top track of neglected garage doors.
Signs Your Seals Need Replacement
Look for these red flags during your next garage inspection.
Visible cracks or chunks missing from the rubber? That's your answer. The bottom seal should sit flush against the concrete floor with no daylight showing underneath. Gently push on it. If it doesn't spring back, replacement is overdue. Discoloration and hardening mean the material has lost its flexibility. Cold drafts at floor level in winter confirm seal failure.
Another clue: compare your heating bills month to month. A sudden spike in November or December often points to poor garage insulation combined with failed seals. If you've already addressed insulation (as covered in our guide to garage door insulation R-value in Curlew), but bills remain high, seals are the next culprit.

Cost & What to Expect
Replacement cost depends on how many seals need work. A bottom seal alone runs $150 to $350 installed, depending on your door's width. Side seals and top seals add $75 to $150 each. Most homeowners invest $300 to $600 for a full perimeter job. It sounds steep until you calculate your heating savings. A well-sealed garage can cut winter energy loss by 15 to 25 percent. In Curlew's climate, that translates to $30 to $50 monthly savings once temperatures drop.
We recommend getting an estimate before deciding. Different door styles require different seal types. Aluminum frames need flexible rubber. Wooden doors sometimes use felt or foam. Only a technician can assess your specific situation and provide accurate pricing. Schedule a free quote to learn your exact cost and timeline.
Installation & Material Quality
Not all weather stripping is created equal. Budget rubber cracks within two seasons. Premium EPDM rubber lasts 5 to 7 years in our Pacific Northwest climate. The difference in upfront cost is minimal, but the longevity gap is huge. Curlew Garage Doors sources heavy-duty seals that withstand temperature swings from below freezing to summer heat.
Installation matters equally. The seal must be compressed evenly against the frame. Gaps at corners or uneven pressure create weak spots where cold air rushes through. A poorly installed bottom seal can actually trap moisture against the concrete, accelerating corrosion of the door's lower edge. This is why DIY installation often fails. Our technicians measure twice, compress the rubber properly, and ensure even contact across the entire perimeter.
Seasonal Timing
Fall is prime time for seal work. You'll notice drafts as soon as temperatures drop, but by then you've already lost heat for weeks. Schedule your weather stripping and seals service in September or October. This gives us availability without the winter rush, and you benefit from better seals before the cold arrives.
If you're preparing your garage door for winter, seals should rank high on your checklist. We've written a complete guide on preparing your garage door for winter that covers this and related maintenance.
Damaged seals cost you real money every heating season. Don't wait until spring. Your garage will feel warmer, your energy bills will drop, and pests stay outside where they belong.

Frequently Asked Questions
How long do garage door seals last? Quality EPDM rubber seals last 5 to 7 years in Curlew's climate. Budget materials fail in 2 to 3 years. Lifespan depends on sun exposure, freeze-thaw cycles, and how often the door operates. Regular inspection catches failure early.
Can I replace weather stripping myself? Technically yes, but improper installation creates gaps that defeat the purpose. Seals must compress evenly and sit flush against the frame. Professional installation ensures performance and saves headaches. The labor cost is worth the reliability.
What's the difference between a bottom seal and side seals? The bottom seal takes ground contact and weather exposure. Side seals run vertically along the frame. Top seals sit above the door. All three prevent drafts, but the bottom seal wears fastest and needs earlier replacement.
Do weather seals help if my garage door isn't insulated? Yes, but incompletely. Seals stop air leakage around the edges. Insulation stops heat transfer through the panels themselves. Together they cut energy loss significantly. See our insulation guide for complete coverage.
Is this covered under my garage door warranty? Most warranties cover manufacturing defects but not wear-and-tear replacement. Check your documentation. If your seals failed prematurely due to defect, we can help file a claim or arrange a repair.
