In our years serving Blachly, we've seen this problem again and again: homeowners notice cold air creeping under the garage door, energy bills climbing, and they assume the whole door needs replacing. The real culprit is usually worn weather stripping and seals. Replacing these components costs a fraction of a new door and solves the draft problem fast.
The Willamette Valley's wet winters and temperature swings take a toll on rubber and foam seals. Weather stripping experiences constant expansion and contraction. UV exposure, moisture, and impacts from the door's movement all accelerate breakdown.
Your garage door has three key seal points. The top seal runs horizontally along the header. Side seals line both vertical edges. The bottom seal (also called a threshold seal) bears the most stress because it absorbs impacts every time your door closes.
Most bottom seals last 5 to 7 years with normal use. If you notice visible cracks, hardening rubber, or gaps wider than a quarter-inch, replacement is overdue. Ignoring these signs means your garage isn't truly insulated, which defeats the purpose of any prior weatherproofing work you've done.
A small draft under the garage door doesn't sound serious. But that gap lets winter air directly into your home. If your garage connects to living spaces, heated air escapes constantly. Studies show weatherproofing gaps waste 10 to 15 percent of home heating energy.
Over a season, that costs money. A weather stripping replacement job typically runs $150 to $400 depending on your door size and seal condition, whereas ignoring it could add $40 to $80 monthly to heating bills. The math favors fixing it now.
Moisture also seeps in through damaged seals. Damp garages invite mold and rust on tools and vehicles. Water damage to wooden door frames becomes expensive quickly. Prevention through proper sealing is always cheaper than remediation.
Our existing post on garage door weatherproofing in Blachly explains what rain actually does to your entire system. It's worth reviewing if you haven't already sealed your door properly.

Not all weather stripping is created equal. Budget options use basic rubber compounds that harden within three years. Mid-range seals blend rubber with foam and last 5 to 7 years. Premium seals use advanced polymers rated for 10+ years.
For Blachly's climate, we typically recommend mid-range seals. They balance durability against cost. Premium seals make sense if you plan to stay in your home long-term or if your garage is heavily used.
The bottom seal deserves special attention. This piece takes direct impact every closing cycle. Upgrading to a reinforced bottom seal (sometimes called a threshold reinforcement) prevents deformation and extends seal life by 2 to 3 years.
Installation matters as much as material choice. Loose seals peel away. Seals installed too tight create friction and wear prematurely. This is why professional installation beats DIY for most homeowners. When you get a same-day estimate from Blachly Garage Doors, we assess your specific door type and recommend seals matched to your situation.
Check your seals monthly during fall and winter. Look for:
Visible cracks or splits in rubber material. Hardened, inflexible seals that don't compress when you press them. Gaps or separation where seals meet the door frame. Daylight visible under the bottom seal when the door is closed.
If you find issues, don't wait. Small problems are cheap to fix. Delayed repairs compound into bigger damage. Water penetration can rot wooden components and compromise door alignment.
For a professional inspection, learn about our complete repair services. Our technicians spot wear patterns you might miss and catch secondary issues before they become costly.
When you call for an estimate, ask specifically about seal options and expected lifespan. A reputable company like Blachly Garage Doors breaks down costs by component, not vague labor charges.
Request a written estimate. It should list seal material grade, installation labor, and any hardware replacements needed. This transparency prevents surprise charges.
Many homeowners assume they need a full door replacement when they actually need $200 in seals and an hour of labor. Ask your technician to diagnose the real problem. If seals are the issue, fix seals. Save major expense for when it's truly necessary.
Don't shop on price alone. Cheap seals installed poorly fail faster than mid-range seals installed right. The cheapest option often costs more over five years.
Worn weather stripping and seals rob your home of comfort and efficiency. Fixing them is straightforward, affordable, and often a same-day job. Schedule a free quote today and get your draft problem solved before the next cold snap hits.
How long do garage door seals last? Mid-range weather stripping lasts 5 to 7 years in Oregon's wet climate. Premium seals reach 10 years. Bottom seals wear fastest due to impact stress. Annual inspection helps catch wear before gaps form.
Can I replace weather stripping myself? Removal is simple, but installation requires precision. Seals must compress evenly to work properly. Loose seals peel and fail within months. Professional installation costs extra but prevents costly repeat work.
What's the difference between weather stripping and a threshold seal? Weather stripping covers the top and side edges of your door. A threshold (bottom seal) is a specialized weather strip designed for impact and compression. They work together for complete weatherproofing.
Will new seals stop all drafts under my garage door? Proper seals eliminate air gaps at the edges. However, if your door frame is warped or misaligned, seals alone won't solve the problem. Our technicians assess door alignment during inspection.
How much does weather stripping replacement cost in Blachly? Typical cost ranges from $150 to $400 depending on door size and seal quality. Request a specific estimate rather than guessing. Call (541) 234-8075 for pricing tailored to your door.
