A customer called last Tuesday morning. Her garage was ice cold, her heating bill had jumped forty dollars that month, and when she opened the side door, cold air rushed in like someone had left a window wide open. The culprit? A deteriorated bottom seal on her garage door. By the time she noticed, drafts had already cost her hundreds in wasted energy. Weather stripping and seals in Siletz fail quietly, but the damage they cause is anything but silent.
Your garage door's weather stripping and seals are the first line of defense against drafts, moisture, pests, and energy loss. When they wear out, you're not just uncomfortable. You're bleeding money and inviting bigger problems down the road. See our guide on .
Siletz sits in the Pacific Northwest, where moisture and temperature swings are relentless. That combination is tough on rubber and foam seals. Most garage door weather stripping lasts five to seven years before it hardens, cracks, or pulls away from the frame.
The culprits are straightforward. UV exposure cracks the material. Freeze-thaw cycles expand and contract the rubber until it loses elasticity. Debris gets wedged between the door and frame, forcing the seal to stretch unnaturally. By the time you feel the draft, the damage is already significant. Read about manual release mechanisms: protecting your family.
The bottom seal takes the worst beating. It drags across concrete, absorbs standing water, and flexes every time the door cycles. If you notice your threshold is cracked, discolored, or missing chunks, your bottom seal is already compromised. That gap might be narrow, but it's enough to let rodents inside and let your heated air escape.
Energy waste is the least of your worries. Yes, drafts will spike your heating and cooling costs. But here's what I've seen go wrong: water intrusion. A failed bottom seal lets rain and snowmelt seep into your garage. Over months, that moisture warps wooden door frames, rusts metal components, and creates conditions for mold to take hold.
Then there's pest entry. Gaps wider than a quarter inch let insects and small rodents inside. Spiders build webs. Ants nest in corners. I've responded to calls where homeowners discovered mice nesting behind stored items because the garage door seal was missing entirely.
Finally, a failed seal puts extra stress on your garage door opener and springs. When the door doesn't seal properly, air pressure changes as it opens and closes, forcing the motor to work harder. Springs last 7 to 9 years under normal conditions, but poor sealing can shorten that lifespan. If your seals are failing, your springs may be next.

Look at the threshold where your door meets the concrete. Is it cracked, missing, or visibly compressed? That's a clear sign the bottom seal needs replacement. Open your garage at night and look for light around the edges. Daylight visible around the frame means seals have failed.
Feel for drafts with your hand. Cold air flowing into your garage in winter, or warm air seeping out in summer, indicates compromised weather stripping. You might also notice an increase in noise when the door opens and closes. Without proper seals, vibrations aren't dampened.
Some homeowners notice their garage smells musty or see water stains on the concrete after rain. Both point to seal failure. The longer you wait, the more damage spreads to the frame itself.
A weather stripping and seal replacement typically costs between 150 and 400 dollars, depending on door size and seal type. Your estimate will depend on whether you need just the bottom seal, full perimeter weather stripping, or both. That cost is minor compared to water damage repairs or replacing hardened springs that failed early.

What's the difference between weather stripping and a bottom seal? Weather stripping refers to the rubber or foam strips that run around the perimeter of your garage door frame (sides and top). The bottom seal is the specialized rubber threshold that runs horizontally along the bottom and makes contact with the concrete floor.
How often should I replace weather stripping? Most weather stripping lasts five to seven years in the Pacific Northwest. Check annually for cracks or hardening. If you see visible damage or feel drafts, replace it sooner rather than later.
Can I replace weather stripping myself? It's possible for simple tasks, but improper installation can leave gaps that defeat the purpose. A professional ensures the seal is level, properly compressed, and aligned with your door movement.
What are the signs of a failed bottom seal? Look for visible cracks, missing chunks, water stains on your garage floor after rain, or drafts you can feel. A badly compressed seal that no longer makes contact with the floor is also a sign of failure.
Will new seals reduce my heating bill? Yes, noticeably. A failed seal forces your HVAC system to work harder to maintain garage temperature. Homeowners typically see a 10 to 20 percent reduction in heating costs after seal replacement, depending on garage usage.
