Your garage door's weather stripping and seals do one job: keep drafts, moisture, and outdoor air from sneaking into your garage. When they fail, your heating bill climbs fast. I'll walk you through the warning signs, why Oregon weather makes this urgent, and what honest replacement costs look like here in Molalla.
Weather stripping doesn't just wear out evenly. Oregon's wet winters, temperature swings, and UV exposure crack rubber and vinyl seals over time. Most bottom seal and threshold seals last 5 to 8 years before they split, harden, or pull away from the frame.
You'll spot trouble before it gets bad. Look for visible cracks in the rubber, gaps where the seal used to sit flush against the door, or pieces actually missing. On cold mornings, feel for drafts around the frame. If your garage feels as cold as outside, your seals are probably gone. Some homeowners notice water pooling inside after heavy rain, which means the bottom seal failed entirely.
The threshold takes the most abuse because it bears weight every time your door opens and closes. If it's cracked or compressed, moisture gets in and can damage the door's bottom edge or nearby framing.
Our location in the Willamette Valley means frequent freeze-thaw cycles, rain that lasts for weeks, and enough humidity to degrade seals faster than drier climates. Winter temperatures drop below freezing regularly, and that's when a failed seal costs you money every single day. A garage loses heat fast without proper sealing, and your HVAC works overtime to compensate.
I've seen homeowners in neighboring areas like Oregon City and Gladstone put off seal replacement for a season and regret it when their heating bills spike. One client waited six months and ended up paying an extra $300 in heat loss before calling us. That's money you'll never get back.
If you've been meaning to check your seals, don't wait until January. Oregon weather accelerates decay, and replacing seals now prevents bigger problems this winter.
Here's where I cut through the confusion. Weather stripping and seal replacement isn't expensive, but pricing varies based on your door type and how much damage exists.
A standard single garage door gets new bottom seal and side seals for $150 to $300, depending on the door width and material. A double-wide door runs $200 to $400. Labor takes 1 to 2 hours. We stock most seal types in common sizes, so we offer same-day service across Molalla and surrounding areas without inflated rush fees.
If your threshold is damaged underneath, replacement adds $100 to $150. Some doors need new weather stripping on the side jambs too, which adds another $75 to $150 per side. Get a free estimate first so you know exactly what you're paying for. No surprises.

Some homeowners tackle this themselves. It's possible if the frame is clean and undamaged. But I've seen more failed DIY jobs than successful ones. Seals must sit perfectly flush or they don't work, and if the frame has rot or damage, a new seal won't solve the draft problem.
Most importantly, a professional inspection catches hidden damage before it costs you thousands. That's worth the service call. If you want to learn more about keeping your whole door in shape, our garage door maintenance guide explains what neglect actually costs you.
If only one seal is cracked or peeling, replacement is straightforward. If multiple seals are failing or the frame is warped, your entire door may be aging. A full inspection tells you whether sealing buys you another 5 years or if a replacement door makes more sense.

How long do garage door weather seals last? Most rubber and vinyl seals last 5 to 8 years in Oregon's climate. UV exposure, freeze-thaw cycles, and moisture accelerate breakdown. Inspect them annually and replace when you see cracks, hardening, or gaps.
Can I replace weather stripping myself? Yes, but it requires a clean frame and careful alignment. If the frame is warped or rotted, a new seal won't seal properly. Professional installation ensures the seal sits flush and performs as designed.
What's the cost difference between bottom seal and full seal replacement? Bottom seal only runs $100 to $150 in labor and materials. Full replacement (bottom, sides, and threshold) typically costs $250 to $400 for a single door, depending on material and frame condition.
Do weather seals really save money on heating? Absolutely. A failed bottom seal lets warm air escape constantly. Replacement pays for itself in 1 to 2 heating seasons through lower utility bills, especially in Oregon winters.
How do I know if my seals are failing? Check for visible cracks, hardness when you press the rubber, gaps between seal and frame, drafts on cold mornings, or water inside the garage after rain. These are all signs replacement is overdue.
