Most people don't think about their garage door until something stops working. But if you live in Manzanita, the salt air and coastal dampness are silently eating away at your weather stripping and seals right now. I've been pulling trucks up to homes here for 15 years, and I can tell you that a failing bottom seal isn't just an inconvenience. It's costing you real money in heating bills and letting moisture damage creep into your garage, your insulation, and eventually your home's frame.
The Oregon coast isn't kind to rubber and foam. Salt spray corrodes metal tracks, but it's the constant dampness that really hammers your seals. Manzanita sits 26 miles south of Cannon Beach, and we get the same relentless moisture year-round. Rain doesn't just fall here; it sits, pools, and finds its way into every gap.
Weather stripping and seals have a lifespan. Most bottom seals last 5 to 7 years before they crack, shrink, or lose their compression. Side seals wear faster if your door sees heavy use or sits in direct ocean wind. Once they fail, water creeps in. Cold air drafts in. Your heating system works overtime.
I've seen homeowners patch a leaking threshold with caulk, thinking that fixes it. Spoiler: it doesn't. Cheap caulk peels away in six months on the coast.
A failing bottom seal creates a draft. That draft pulls conditioned air out of your garage and heated air from your home if the garage connects to living space. Over a winter season, that can add 15 to 25 percent to your heating bill. For a household spending $150 a month on heat, that's an extra $225 to $450 by March.
Water is worse than air. When rain gets past your seals, it pools on the garage floor. Moisture migrates up wooden door frames and into wall cavities. Mold starts quietly. By the time you smell it, remediation costs thousands.
This is also a safety issue. Wet floors in a garage are slip hazards, especially if you have vehicles parked inside. And if water reaches your door's bottom bracket or torsion spring assembly, rust accelerates the wear cycle. A $200 seal replacement now beats a $2,000 spring and track replacement later.

Not all seals are equal. Your garage door has four seal points: the bottom seal, two side seals, and a top seal. Each one handles different water and air infiltration.
The bottom seal (or bottom weather stripping) is a rubber or vinyl extrusion that compresses against the concrete threshold as the door closes. If your threshold is uneven or settling, the seal won't compress evenly, and gaps open up. That's when you get that "I can feel the draft" complaint.
Side seals run along the vertical tracks. They're narrower but critical. Many homeowners miss them during inspections because they're less obvious than a cracked bottom seal.
For Manzanita specifically, we recommend thicker, marine-grade weather stripping. Standard residential seals fail faster here. The cost difference is usually 20 to 30 percent more upfront, but you get 8 to 10 years instead of 5 to 7. We've written more about long-term maintenance strategies in our garage door maintenance budget guide, which covers seal replacement alongside other tune-ups.
Walk into your garage on a cold, rainy day. Do you feel a draft at the bottom of the closed door? Can you see light coming through gaps on the sides? That's your answer.
Open the door and look at the bottom seal. Is the rubber cracked, hardened, or peeling away from the metal channel? Press your finger against it. Does it compress, or is it rock hard? Hard rubber means it's not sealing anymore.
Look at your concrete threshold. Is it cracked or uneven? A broken threshold can't support a seal properly, and you'll need to address that first.
Check the side seals and top seal too. Consistency matters. If one seal is failing, the others aren't far behind.

A bottom seal replacement typically runs $150 to $300 depending on your door size and seal type. Side seals add another $100 to $150 each. If your threshold is damaged and needs repair or replacement, add $200 to $500.
Our garage door cost and pricing guide breaks down typical expenses across common repairs. Weather stripping usually falls in the affordable range compared to spring replacement or opener repair.
If your door is also losing heat through the panels themselves, insulation upgrades might make financial sense. Better insulation plus new seals gives you the biggest return. We've seen homeowners recover those costs in heating savings within two winters.
The difference between a DIY seal replacement and a professional job is precision. Your door tracks must be aligned. Your threshold must be level. The seal material must match your door's channel dimensions. One millimeter off, and you're back to drafts.

How often should I replace garage door weather stripping? On the Oregon coast, plan for replacement every 5 to 7 years. Salt air and moisture accelerate wear. Standard residential seals in inland climates last 7 to 10 years.
Can I replace weather stripping myself? Yes, for bottom seals on single-car doors. You'll need to remove the old extrusion from the channel, clean debris, and slide the new seal in. Side seals require more precision. If you're unsure, hire a pro.
What's the difference between a threshold and a bottom seal? The threshold is the concrete or metal lip at the base of the garage opening. The bottom seal is the rubber/vinyl strip that compresses against it. Both matter for a tight fit.
Will new seals reduce my heating bill? Yes. Eliminating drafts from failed seals can reduce heating costs by 10 to 20 percent depending on how badly they've failed and whether your garage is insulated or connected to living space.
Why does my new seal still leak after one year? Likely causes: misaligned tracks, uneven threshold, or incorrect seal size. Have a technician inspect the tracks and door alignment. A poor fit defeats even quality seals.
