How Often Should You Replace Weather Stripping & Seals in Clackamas?
2026-07-20 7 min read A2Z Garage Doors
You don't think about your garage door until something goes wrong, and by then, water's already sneaking in around the edges. After 15 years on service calls across Clackamas and the surrounding Portland metro, I can tell you weather stripping and seals fail silently. They don't snap like springs. They just slowly stop doing their job, letting drafts, moisture, and pests slip past your threshold. Most homeowners replace them every 3 to 5 years, depending on Oregon's wet winters and how hard they work.
Why Weather Stripping Fails Faster Than You'd Think
The Pacific Northwest isn't kind to rubber and foam. Our climate cycles between heavy rain and temperature swings that crack seals from the inside out. A quality bottom seal should last 3 to 4 years under normal Clackamas conditions. If your garage faces west or gets direct sun exposure, that timeline shrinks to 2 to 3 years.
I've pulled weather stripping off doors where homeowners never replaced it once in eight years. The rubber had turned brittle, split in places, and the draft you could feel at your feet was worse than leaving the door wide open. That's when energy bills creep up and moisture damage starts eating at your concrete floor and wall framing.
Signs Your Seals Need Replacement Now
Check your bottom seal first. If you see daylight under your garage door when it's closed, that's your signal. Press on the rubber with your finger. Does it feel hard and inelastic, or does it bounce back? Hard rubber won't compress against your threshold anymore.
Look at the side seals and top seal next. Cracks, splits, or chunks missing are obvious. But the sneaky ones are the seals that look fine until it rains and you spot water pooling inside. That means the seal's compression is gone, even if it looks intact from across the garage.
If you're already keeping up with a regular garage door maintenance schedule for Clackamas homeowners, you'll catch worn seals during your annual inspection. That's the smart approach. Preventive replacement costs far less than water damage repair.

What Replacement Actually Costs
A bottom seal replacement typically runs $150 to $300 depending on your door size and seal type. Side seals add another $100 to $150 per side. Top seals are usually $75 to $150. If you need all three replaced together, expect a total estimate in the $400 to $600 range for materials and labor.
The cost varies based on your specific door dimensions and whether you've got a standard garage or a taller commercial opening. Our team provides a free estimate so there's no guessing. We'll inspect all your seals and tell you exactly what needs work and what doesn't. Get a same-day estimate from Garage Door Clackamas when you call.
Comparing that $400 to $600 against water damage repairs running $2,000 to $5,000 makes the choice obvious. Seal replacement is one of the cheapest preventive maintenance tasks you can do.
Choosing the Right Seal Material
Not all weather stripping is created equal. Rubber and EPDM foam are the industry standards. Rubber lasts longer but costs slightly more upfront. Foam is softer and seals tighter initially but can compress over time.
For Clackamas's rainy climate, I recommend EPDM rubber. It handles freeze-thaw cycles better and resists UV breakdown. It'll give you that full 4 to 5 year lifespan. Cheaper foam might need replacement every 2 to 3 years, which means more truck calls and frustration.
Your garage door opener and springs also need regular attention to function properly alongside fresh seals. If you haven't checked your garage door lubrication in Clackamas recently, now's a good time to bundle both services.

Frequently Asked Questions
How do I know if my bottom seal is failing? Look for daylight under your closed door, visible cracks in the rubber, or water pooling inside after rain. Press the seal with your finger. If it doesn't bounce back or feels hard and brittle, replacement is overdue.
Can I replace weather stripping myself? It's possible but tricky. The seal must be installed level and compressed evenly against the threshold. Improper installation leaves gaps. Most homeowners benefit from professional installation to guarantee no drafts remain.
What's the difference between a threshold and a bottom seal? A threshold is the horizontal piece at the garage floor entrance. A bottom seal is the rubber gasket that compresses against the threshold. Both work together to block water and pests.
How long do weather seals last in Oregon's climate? Expect 3 to 5 years in the Portland and Clackamas area. Doors facing west or in direct sun wear faster. Freeze-thaw cycles shorten lifespan compared to milder climates.
Should I replace all seals at once or just the worn one? If one seal is failing, the others are likely close behind. Replacing all three (top, sides, bottom) at once costs less than multiple service calls and ensures consistent protection across your entire door.
