A customer called last Tuesday asking why cold air was pouring into her garage despite the door being closed. After 15 years on service calls around Cottage Grove, I knew exactly what she'd find: worn weather stripping and a failed bottom seal. The answer is straightforward. Weather stripping and seals prevent drafts, reduce energy loss, and keep pests out of your garage. When they wear out, your heating and cooling costs climb fast.
Your garage door isn't solid rubber or foam. It's made of panels with gaps around the edges. Weather stripping fills those gaps. The rubber or vinyl strips run along the top and sides of the door opening. The bottom seal (also called a threshold) sits underneath and takes the most abuse since it drags across your driveway every time the door opens or closes. See our guide on permits and regulations: what every homeowner should know.
These components work together to create an air-tight barrier. Without them, heated air escapes in winter and cool air leaks out in summer. Pests like spiders, rodents, and insects find their way in through gaps. If you've got a climate controlled garage, poor seals cost you real money month after month.
The Pacific Northwest throws everything at garage doors. Rain, freeze-thaw cycles, UV exposure, and constant moisture all degrade rubber and vinyl faster than in drier regions. A bottom seal that might last 5 to 7 years in Arizona might only make it 3 to 4 years here in Cottage Grove. Read about preparing your garage door for storm season: essential tips.
I've pulled off seals that were cracked, hardened, or completely disintegrated. Some customers don't notice until they see water pooling on the garage floor during heavy rain. By then, the damage is done. Preventive replacement saves you from water damage, mold, and ruined stored items.
When seals fail, you get draft. That draft turns into higher utility bills. Think of it this way: a failed bottom seal is like leaving a window cracked open all winter. Your furnace works overtime to compensate.
Check your seals twice a year, especially before winter and after our rainy season. Look for cracks, gaps, or areas where the rubber has become hard and brittle. If you can see daylight around the edges of a closed door, your seals are past their prime.

How long do garage door seals last? In Cottage Grove's wet climate, bottom seals and weather stripping typically last 3 to 5 years with regular use. UV exposure, freeze-thaw cycles, and constant moisture accelerate wear. Annual inspection helps catch failure early.
Can I replace seals myself? You can remove old seals, but proper installation requires precision to ensure a tight fit. Misaligned seals won't seal drafts effectively. Professional replacement guarantees a weather-tight barrier and proper alignment with your door frame.
What's the difference between weather stripping and a bottom seal? Weather stripping runs along the top and sides of your door frame, sealing horizontal and vertical gaps. The bottom seal (threshold) runs across the bottom and handles moisture and ground contact, making it wear faster.
Will new seals reduce my energy bills? Yes. A failed bottom seal or worn weather stripping lets conditioned air escape constantly. Replacing them typically reduces heating and cooling loss by 10 to 20 percent, depending on how badly the old seals had deteriorated.
How do I know if my seals need replacement? Signs include visible cracks or hardening, daylight visible around a closed door, drafts, water entering the garage during rain, or unusual heating and cooling costs. Have a technician inspect if you're unsure.
