A worn bottom seal or damaged weather stripping around your garage door doesn't just let in a chilly draft. It opens the door to water damage, pest infiltration, and premature wear on your entire system. The good news: catching this early and replacing seals before they fail saves you hundreds in repair bills down the road.
Oregon's wet winters and temperature swings hit garage door seals hard. Rain, ice melt, and constant humidity break down rubber and foam much faster than you'd expect. Most weather stripping lasts 5 to 7 years before it cracks, hardens, or separates from the frame.
The bottom seal takes the worst beating. It sits inches from the ground where water pools, snow piles up, and salt or debris can lodge against it. When that seal degrades, water seeps under the door and into your garage. In Kerby and the surrounding Salem Valley area, this isn't just an inconvenience. Standing water in your garage leads to mold, damaged storage, and corroded metal.
Side seals and top seals wear too, but more slowly. You'll notice drafts first. Cold air flows in around the edges, and your heating bill climbs. Then insects find their way in. Spiders, ants, and wasps exploit tiny gaps in worn seals.
Look for these red flags during your monthly garage inspection:
Visible cracks or hardening. Run your finger along the rubber. If it feels brittle or crumbles slightly, it's near the end of its life.
Water pooling inside after rain. This almost always means the bottom seal or threshold is compromised.
Daylight visible under the closed door. Shine a flashlight inside the garage at dusk with the door closed. If you see light leaking through gaps, seals are worn.
Cold drafts or warm air escaping. If your garage feels significantly colder than it should, check where the door meets the frame.
Insects or debris inside the garage. Pests use damaged seals as highways into your space.
If you've experienced issues with your door sticking or refusing to open, worn seals could be a contributing factor. Learn more in our guide on garage door stuck in Kerby and why it won't open.

The cost to replace weather stripping & seals varies based on which seals need work and your door's size. A bottom seal replacement runs less than most repairs. Adding side seals or a full threshold replacement costs more. Most homeowners in Kerby should expect a straightforward estimate to cover labor and materials without surprise fees.

Quality matters. Cheap aftermarket seals fail faster. Manufacturer-grade materials last longer and seal tighter. When you're comparing cost, ask whether the replacement includes high-density rubber or foam, not thin plastic substitutes.
Replacing a bottom seal yourself is possible if you're handy. The door must be fully closed and the old seal removed cleanly. New seal material slides into the channel at the base. However, if the seal channel is damaged or if you're replacing side or top seals, the job becomes fiddly fast.
Misaligned seals create gaps. A seal that's even slightly crooked won't compress properly when the door closes, and you've wasted the material and time. Professional installation ensures the seal sits flush and compresses evenly across the full width.

If only the bottom seal is cracked and the frame is intact, replacement is the answer. If the threshold itself is bent or rotted, you may need threshold replacement, not just a new seal. A bent threshold won't hold a new seal in place.
Inspect the frame around all seals too. Rust, rot, or damage to the frame means the seal won't seal properly no matter how new it is. In those cases, we address the underlying frame damage first.
Once new seals are installed, keep them working by clearing debris around the door base, especially after heavy rain or snow. Don't let leaves or dirt accumulate where the bottom seal meets the ground. A quick vacuum or sweep every few weeks prevents premature wear.
Check your seals each fall before winter hits. Kerby winters are wet. Addressing a small gap now beats dealing with water damage in January.

How long do garage door seals last? Most weather stripping and bottom seals last 5 to 7 years in Oregon's wet climate. Side and top seals can last slightly longer if protected from direct water exposure. Inspect annually and replace at the first sign of cracking or hardening.
Can I replace the bottom seal myself? Yes, if the frame is intact and you're comfortable with basic tools. Slide the old seal out, clean the channel, and insert the new seal. Professional installation ensures proper compression and alignment, reducing the risk of gaps and future leaks.
What's the difference between a bottom seal and a threshold? A bottom seal is the rubber strip that compresses against the ground when the door closes. The threshold is the structural part of the frame at the base. Both work together. A worn seal can be replaced; a bent threshold typically requires replacement of the entire base unit.
How much does weather stripping replacement cost in Kerby? A standard bottom seal replacement typically costs less than most garage door repairs. Full estimates depend on your door size and which seals need work. Call 1-541-813-5949 for a same-day estimate with no hidden fees.
What happens if I ignore worn seals? Water seeps into your garage, causing mold, rust, and damage to stored items. Drafts increase heating costs. Pests and insects find entry points. Small gaps become major problems. Address worn seals before secondary damage spreads.
