In our years serving Gates, we've seen this problem again and again: homeowners ignore a worn bottom seal, energy bills spike 15 to 20 percent, and by the time they call, the damage spreads to the door frame itself. Weather stripping and seals aren't glamorous, but they're your first line of defense against drafts, moisture, and the Oregon climate.
The Willamette Valley's wet winters are relentless. Rain, freeze-thaw cycles, and temperature swings degrade rubber and foam seals faster than most homeowners expect. A typical rubber bottom seal lasts 5 to 7 years before it hardens, cracks, or compresses so much it no longer blocks air and water.
We've pulled off seals that looked fine from a distance but crumbled when touched. Once the threshold seal fails, cold air rushes in, moisture seeps underneath, and rust begins eating at the door frame and tracks. In extreme cases, we've seen water damage spread into the garage and into adjacent walls. That's when a $150 repair becomes a $2,000 frame replacement.
The seals around your garage door come in three main types: the bottom seal (or sweep), the side seals, and the header seal at the top. Each one wears at different rates depending on how often you open and close the door and how much direct weather exposure it gets.
Look for these warning signs today. If you see daylight under the door when it's closed, your bottom seal has compressed. If you feel a cold draft or smell moisture in the garage on humid mornings, the threshold or side seals are compromised. Discolored or chalky rubber is a clear sign the material is degrading.
Pay special attention after heavy rain. Walk around your garage and look for water pooling near the base of the door or inside the garage. Even small puddles mean the seal isn't doing its job. In Gates and nearby Salem, we see this most often in fall and winter when the rain doesn't stop for weeks.
One easy test: close the door and turn off the lights. If you see light bleeding in from outside, you have a draft problem. Grab a piece of paper and try to slide it under the door. If it moves freely, the bottom seal needs replacement.
A new bottom seal typically costs between $80 and $200 for materials and labor, depending on your door's width and the seal type. Side seals and header seals run $50 to $150 each. If all three need replacement, budget $250 to $500 total. Compare that to a single month of inflated heating bills or water damage repair, and the math is clear.
Garage Door Gates offers same-day service for seal replacement in most cases. If you call before 2 p.m., we can often schedule a technician the same afternoon. The job takes 30 to 60 minutes. We'll inspect your entire door assembly, check the tracks for rust or debris, and make sure the threshold is level before installing new seals. A crooked threshold wastes even the best new seal.

Once new seals are installed, maintenance is simple but critical. Every three months, inspect the seals visually. Wipe them down with a dry cloth to remove dirt and debris. Keep the tracks clean so the door closes evenly and the seals compress uniformly. A door that sticks or closes crooked will wear seals unevenly and fail early.
In winter, check seals after heavy rain or snow. Clear any ice or standing water around the base of the door. If you live in an area prone to flooding or high moisture, consider upgrading to commercial-grade seals, which last longer and handle extreme weather better.
If your garage door hasn't been serviced in over a year, schedule a full maintenance tune-up. We'll check springs, cables, opener function, and all seals as part of a complete inspection. See our budget-friendly garage door maintenance guide for more details on what's included.
Sometimes a single seal can be replaced. Other times, the door frame or threshold has warped or rusted so badly that new seals won't seal properly. If you've had water damage or the door is over 15 years old, we may recommend replacing the entire door assembly instead of just the seals. We'll give you an honest cost estimate and let you decide.
Learn more about garage door replacement costs in Gates if you think replacement might be necessary. If your door is relatively new and only the seals are worn, a replacement is the smart move.

How long do weather seals last on a garage door? Bottom seals typically last 5 to 7 years with normal use. Side and header seals may last 7 to 10 years. The exact lifespan depends on climate, usage frequency, and maintenance. Oregon's wet winters accelerate wear.
Can I replace weather stripping myself? Yes, if you're handy and have basic tools. Removal is straightforward: unscrew the old seal bracket and slide out the worn seal. Installation takes 15 to 30 minutes per seal. If you're unsure, call a professional to avoid installation errors that waste new seals.
What's the difference between a bottom seal and a threshold? The bottom seal (or sweep) is the rubber strip attached to the door's bottom edge. The threshold is the metal or composite track at the base of the opening. Both work together to stop drafts and water. Both may need attention during service.
Will new seals stop all drafts? New seals eliminate drafts caused by worn rubber. If your door is warped, doesn't close evenly, or the threshold is uneven, drafts may persist. We inspect these issues before sealing to ensure the repair actually works.
How much does weather stripping replacement cost near me? In Gates, typical bottom seal replacement costs $80 to $200. Side seals and header seals run $50 to $150 each. Full seal replacement across all three positions typically costs $250 to $500. Call us for a free estimate.
