Your garage door's weather stripping and seals are the only barrier between your home and Oregon's wet, unpredictable climate. When they fail.and they will.you lose heat, gain drafts, and invite moisture damage that spreads fast. Here's what you need to know to catch the problem early.
Weather stripping isn't decoration. It's a rubber or foam gasket that runs along the bottom, sides, and top of your garage door. Its job: seal gaps that would otherwise let cold air, rain, and pests straight into your garage and crawlspace.
The bottom seal takes the hardest beating. Every time your door cycles, it compresses and relaxes. Over 5,7 years, UV exposure, temperature swings, and friction crack it. When it fails, water pools against your threshold. Insects find their way in. Your heating bill climbs.
I've seen homeowners ignore this until water damage reached their foundation. That's a $3,000+ repair that starts with a $200 seal replacement.
Look for these red flags:
Visible cracks or gaps. If you see light under the door when it's closed, seals are compromised.
Water stains on the floor. Especially after Glendale rain, check around the door frame and threshold.
Drafts in the garage. Cold air flowing in means the seal isn't doing its job.
Peeling or hardened rubber. Seals shrink and harden in cold weather. Once they're brittle, they won't compress properly.
Visible mold or moisture. This is the emergency flag. Moisture trapped in the garage breeds mold and rots wood framing.
If you've already noticed cold weather problems with your door, failing seals are often the culprit. Don't wait for the next freeze cycle to act.

Glendale's freeze-thaw cycle is brutal on rubber. Winter temperatures drop, seals contract and crack. Spring thaw brings moisture that pools against the bottom seal. By summer, UV rays have hardened what's left.
The threshold seal.that horizontal rubber piece at the base.wears fastest. It bears the weight of the door and flexes with every opening. After 5,7 years, it compresses permanently and stops sealing.
Side seals fail next, often silently. You won't notice until you feel the draft or see moisture creeping up the wall.
Top seals last longest but still need inspection every 2,3 years. When they go, cold air pours in directly above your head.
A quality bottom seal runs $150,$300 installed. Full seal replacement (all sides) typically costs $400,$700. That's cheap compared to:
- Water damage repair: $1,500,$5,000+ - Mold remediation: $2,000,$6,000+ - Foundation damage: $3,000,$10,000+
Get a free estimate from Glendale Garage Doors. We'll inspect all seals and tell you exactly what needs replacing.no upsell. Most same-day replacements take 1,2 hours and preserve your door's warranty.
Replacing a bottom seal yourself is possible if you're handy. You'll need a hex key, new seal kit ($40,$80), and 30 minutes. Loosen the bolts, slide the old seal out, slide the new one in, tighten.
But here's the catch: if your door is out of balance or the frame is bent, a new seal won't help. Water will still find cracks. You'll waste money and time.
Professional replacement includes frame inspection, alignment verification, and proper compression adjustment. If we find deeper issues.like roller damage or springs that are failing.we'll tell you upfront.
Clean the seal and threshold monthly. Dirt and debris prevent proper compression.
Keep gutters clear. Water backing up into your fascia runs down behind the door frame.
Check seals before winter and after heavy rain. Early spotting saves thousands.
If you're replacing seals, consider upgrading to commercial-grade rubber. It lasts 8,10 years instead of 5,7, especially in our Pacific Northwest winters.
Don't wait for visible damage. Schedule an inspection online or call us at (541) 995-7374. We'll assess your weather stripping and seals, give you a cost estimate, and explain what's happening in plain language.
Glendale Garage Doors has handled hundreds of water damage calls that started with ignored seals. We'd rather help you prevent the problem than fix it after the fact.

How often should I replace my garage door weather stripping? Every 5,7 years under normal conditions. Glendale's wet climate and freeze-thaw cycles may shorten this to 4,5 years. Inspect annually and replace when you see cracks, gaps, or permanent compression.
Can I replace just the bottom seal, or do I need all four sides? You can replace seals individually, but we recommend inspecting all four during service. Side and top seals often fail around the same time. A full replacement protects your entire threshold.
What's the difference between a bottom seal and a threshold seal? The bottom seal is the vertical rubber gasket. The threshold is the horizontal metal or rubber piece at the very base of the opening. Both are critical; both wear out together.
Will new seals fix my drafts? Yes.if drafts are caused by failed seals. If your door is misaligned, bent, or has bent rollers, new seals alone won't solve the problem. We inspect the whole door to diagnose the real cause.
How much will weather stripping & seals cost me in Glendale? Bottom seal replacement: $150,$300. Full seal kit: $400,$700 installed. Get a free estimate by calling (541) 995-7374. Pricing depends on your door size and seal condition.
