A customer called last Tuesday saying her garage felt drafty. She'd noticed cold air creeping in around the bottom of the door, and her heating bill had jumped noticeably. After a quick inspection, we found her weather stripping & seals in Nordland had deteriorated almost completely. The bottom seal was cracked, the threshold gasket had shrunk, and she'd been losing heated air all season. The good news? Replacement took two hours, cost less than she expected, and solved the problem entirely.
If you're experiencing similar drafts or noticing your garage temperature dropping, worn seals are likely the culprit. We'll walk you through the warning signs, what replacement actually costs, and why acting now beats waiting until winter really hits.
Worn seals announce themselves in several ways. Look for visible cracks, gaps, or hardening along the bottom seal and side jambs. If you see daylight under the garage door when it's closed, the threshold gasket has probably compressed beyond function. You might also notice dust, leaves, or insects entering the garage more easily than before.
Cold air drafts are the most obvious indicator. Run your hand along the perimeter of a closed door on a chilly day. Any noticeable breeze means seals are compromised. Some homeowners also report increased pest activity or moisture buildup, both tied to failing weather barriers.
Another red flag: a spike in your heating or cooling costs. If your HVAC system is working harder to maintain temperature, damaged seals are forcing it to compensate. Over time, this small inefficiency becomes a real expense. Most seals last between five and eight years depending on climate and usage, so if yours are older, replacement is overdue.
Our Pacific Northwest winters bring rain, wind, and temperature swings. A small gap in your seals can let water infiltrate your garage foundation, leading to rust on door components, mold growth, or structural damage. Once water gets in, repair costs spike fast.
Replacing seals now, before cold and wet weather intensify, keeps your garage protected. You'll also lock in lower heating costs through the winter months. The cost of replacement is minimal compared to fixing water damage or replacing a corroded spring later. Check out our garage door maintenance guide for winter preparation to see how seals fit into your overall protection plan.

Many homeowners assume seal replacement is expensive. Reality is much friendlier to your budget. A complete weather stripping and bottom seal replacement typically runs between $150 and $350, depending on door size and seal type. If you only need the threshold gasket replaced, expect $100 to $200. We offer a free estimate so you'll know exactly what you're paying before we start work.
Compare that to the cost of heating a drafty garage all winter (often $20 to $40 extra per month) or repairing water damage (hundreds to thousands). The math is simple. For a detailed breakdown of pricing, see our cost guide to weather stripping & seals.
Some seals can be replaced by homeowners with basic tools. The bottom seal and threshold are straightforward if you're mechanically inclined. However, side and top seals require precise measurement and alignment to function correctly. Mistakes here mean drafts persist, defeating the purpose.
Professionals ensure seals are cut to exact specifications, installed flush with the frame, and properly compressed. We also inspect the door frame for damage that might prevent seals from sealing properly. That inspection alone often saves money by catching issues early. If you want to explore our full weather stripping and seals service, we're ready to help.
Properly sealed garage doors reduce heating loss by 10 to 15 percent in that space. If your garage is attached to your home, that number climbs. Better seals mean your furnace doesn't work as hard, your ducts stay cleaner, and your utility bills drop month after month. Over five years, those savings easily cover the replacement cost multiple times over.
Nordland homeowners in similar climate zones report noticing the difference immediately after installation. Garages stay warmer, moisture problems disappear, and the door operates more smoothly because components aren't corroded by water intrusion.
Don't wait for winter to hit full force. Worn seals create cascading problems that cost far more to fix than prevention. Call us at (360) 401-4628 or schedule a free quote to get your seals inspected and replaced before the heavy rain season arrives. Same-day estimates are available for most Nordland addresses.
How often should I replace garage door seals? Weather stripping typically lasts five to eight years depending on exposure and climate. Nordland's wet winters can shorten this timeline, so inspect annually and replace when you notice cracks, hardening, or gaps.
Can I replace just the bottom seal, or do all seals need replacement? You can replace seals individually. However, if one seal is worn, others likely are too. We often recommend replacing the entire set during one visit to ensure consistent protection and save on labor costs.
Will new seals stop all drafts immediately? Yes, properly installed seals eliminate visible gaps and drafts. If drafts persist after replacement, the frame itself may be warped or the door may have alignment issues requiring adjustment.
How long does seal replacement take? Most jobs take one to three hours depending on door size and seal complexity. We schedule same-day appointments whenever possible so you're not left with an unprotected garage.
What's the difference between weatherstripping and a bottom seal? Weatherstripping covers side and top jambs, while the bottom seal (also called a threshold gasket) protects the door's bottom edge where it meets the ground. Both are essential for a complete seal.
