Weather Stripping & Seals in Wilsonville: Stop Drafts and Energy Loss
2026-05-27 7 min read
A customer called last Tuesday asking why her heating bills had spiked in spring. During our inspection, we found the bottom seal of her garage door had cracked and separated from the frame. That single gap was letting conditioned air escape and letting outside moisture creep in. Weather stripping and seals are not glamorous, but they're foundational to keeping your home efficient, dry, and pest-free.
Why Weather Stripping Fails
Garage door seals endure constant movement and temperature swings. In Wilsonville, our mild winters and wet springs put real stress on rubber and foam materials. UV exposure, repeated compression cycles, and moisture penetration break down even quality seals over time. See our guide on motion detection: protecting your family.
The bottom seal typically wears first because it bears the load of the door's weight and contacts the threshold directly. Side and top seals experience less stress but still degrade. Most seals last 5 to 7 years with regular use. If yours is cracked, hardened, or visibly compressed, replacement is overdue.
The Real Cost of Poor Seals
Drafts aren't just uncomfortable. A gap under your garage door can account for 10 to 15 percent of your home's total air leakage. That means higher utility bills year-round. In winter, heated air escapes. In summer, cool air does the same. Read about preparing your garage door for hot weather: essential tips.
Beyond energy loss, gaps invite pests, dust, and moisture. Rodents need only a quarter-inch opening. Once inside, they damage insulation and wiring. Moisture promotes mold, rust on your door frame, and rot in surrounding wood. The threshold itself can warp or crack if water sits against it repeatedly.
Replacing seals costs far less than remedying pest damage, mold remediation, or reframing a garage entry. A quality bottom seal and weatherstripping package runs between 150 and 400 dollars, depending on your door's size and material. That investment returns itself in energy savings within 12 to 18 months.
Types of Weather Stripping & Seals
Not all seals are created equal. Rubber is durable and compresses well but can crack in cold. Foam is softer and cheaper but degrades faster in sun. Vinyl blends the two, offering reasonable durability and flexibility.
The bottom seal, also called the bottom astragal or gasket, sits in a track or channel and compresses upward as the door closes. It must seal against the threshold without binding the door's operation. Side seals and top seals usually attach to the frame itself and compress against the door panel.
Professional installation matters. A seal that's too loose won't seal. One that's too tight binds the door and strains the opener and springs. Garage Door Wilsonville installs every seal to exact compression specs, ensuring smooth operation and genuine draft prevention.

When to Replace vs. Repair
Small cracks in foam seals sometimes warrant a repair with weatherstripping tape. But tape is temporary. If the seal is more than 20 percent compressed, hardened, or missing chunks, replacement is the right call.
If you're already planning a repair visit, bundle seal replacement with other work. Many homeowners discover seal issues while troubleshooting other problems. Our garage door repair guide covers signs that warrant a professional inspection.
Newer doors with insulation often include better factory seals. If you're considering garage door installation, upgraded seals and weatherstripping should be part of your material choice conversation.
Installation and Maintenance
Installation requires removing the old seal cleanly and measuring the track or channel precisely. Debris left behind prevents proper sealing. The new seal must be cut to length and seated firmly, with no gaps at corners or joints.
Once installed, seals need minimal maintenance. Keep the threshold clean and free of dirt. In Wilsonville's rainy climate, check seals annually for water pooling or visible separation. A quick visual once a year catches problems early.
Your garage door system works harder when seals fail. Worn seals force your opener to work longer and put extra strain on springs and rollers. Replacing seals is preventative maintenance that protects your entire assembly.

Frequently Asked Questions
How often should I replace my garage door seals? Most seals last 5 to 7 years. Check annually for cracks, hardening, or compression loss. Climate and door usage influence lifespan. Wilsonville's moisture accelerates wear, so inspect every spring.
Can I replace seals myself? Small foam weatherstripping can be a DIY job. Bottom seals require precise measurement, cutting, and installation in a track. Misalignment causes binding and opener strain. Professional installation ensures proper compression and function.
What's the difference between a bottom seal and weatherstripping? A bottom seal sits in a track beneath the door and compresses upward as it closes. Weatherstripping attaches to the frame sides and top, compressing against the door panel itself. Both are essential.
Will new seals reduce my energy bill? Yes. Seals stop air leakage, which can represent 10 to 15 percent of home heat loss. Combined with an insulated door, proper seals deliver measurable monthly savings on heating and cooling.
How long does seal replacement take? Most jobs take 1 to 2 hours, depending on seal type and door condition. We offer same-day service across Wilsonville, so scheduling is quick and convenient.
