In our years serving Sandy, we've seen this problem again and again: homeowners ignore a small draft around their garage door, then face a $400+ heating bill spike by December. Weather stripping and seals are your first line of defense against Oregon's cold, wet climate. Without them, conditioned air leaks out, pests crawl in, and your garage becomes an uninsulated liability.
Sandy sits at 2,100 feet elevation in the Cascade foothills. Winter temperatures drop below freezing for months, and moisture from spring runoff creates freeze-thaw cycles that destroy worn seals fast. Rubber and foam materials become brittle after 3 to 5 years of this punishment.
The bottom seal takes the worst beating. It flexes every time your door opens and closes, and standing water from rain and snowmelt accelerates deterioration. We've pulled off seals so decomposed they crumbled in our hands. By that point, the damage is already done: cold air pours in, warm air escapes, and your HVAC system runs overtime.
Most homeowners don't notice until they feel a draft or spot daylight under the door. By then, you've lost months of efficiency.
A proper seal system includes the bottom seal, side seals, and top seal. Together, they create an airtight threshold that blocks wind, rain, insects, and cold air from entering your garage and attached home.
The bottom seal is critical. It bears the most stress and needs replacement every 3 to 5 years in Sandy's climate. Side seals prevent drafts from creeping in along the door's edges. Top seals stop heat from rising and escaping.
Think of it like weatherproofing your front door. You wouldn't leave your entryway exposed. Your garage door is the same. If your attached garage is uninsulated, drafts affect your living spaces directly.

Feel a draft at floor level when the door is closed. That's your bottom seal failing. Look for visible cracks, peeling, or gaps in the rubber or foam. If you see daylight between the door and frame, replacement is overdue.
Another red flag: insects or spiders nesting inside your garage. Gaps in seals are an open invitation. We've found wasp nests, spiders, and even rodent entry points traced directly back to deteriorated weather stripping.
Check the threshold too. It should sit flush against the door. If there's a gap or the threshold is cracked, water pools and cold air rushes in. This is especially dangerous in Sandy during spring thaw and heavy winter rain.
A basic bottom seal replacement runs $150 to $250, plus labor. Full seal replacement for all four sides costs between $300 and $500. That might sound high, but it pays for itself in heating savings within one heating season if your garage is attached to your home.
We offer same-day estimates and installation for most jobs. No waiting weeks. The sooner you seal the gaps, the sooner you stop losing energy and money. Schedule a free quote today and learn the exact cost for your door.
Our team inspects your entire seal system during the estimate. Sometimes only the bottom seal is worn. Other times, side seals are compromised too. We'll give you an honest assessment and a clear price before any work begins.

Professional installation ensures seals sit perfectly flush and seal completely. A DIY install often leaves small gaps that defeat the purpose. We use commercial-grade materials rated for Oregon's wet winters, not hardware store foam that hardens and cracks.
After installation, maintenance is minimal. Rinse seals with a garden hose twice a year to remove dirt and debris. In fall, inspect for cracks before cold weather hits. In spring, check for water damage after snowmelt.
Proper seals also protect your garage door itself. Water that pools against a worn bottom seal can rust hinges, corrode the door frame, and weaken the panels. Prevention is far cheaper than repair.
Your garage door is part of your home's thermal envelope. Neglecting weather stripping and seals costs you money every single day the door is installed. In Sandy's climate, that adds up fast.
Don't wait for winter to arrive. Call Garage Door Sandy at 541-909-8132 or get a same-day estimate. We'll inspect your seals, explain what's failing, and give you a transparent price for repair or replacement.
Your home's comfort and your wallet will thank you.
How long do garage door seals last in Sandy? Rubber and foam seals typically last 3 to 5 years in Sandy's freeze-thaw climate. Moisture, temperature swings, and door use accelerate wear. We recommend inspecting seals annually and replacing them when you see cracks or gaps.
Can I replace weather stripping myself? You can, but professional installation is more reliable. We measure, cut, and install seals to ensure a perfect flush fit with no gaps. DIY installations often leave small leaks that compromise the seal's effectiveness.
What's the difference between a bottom seal and a threshold? The bottom seal is the rubber or foam strip attached to the door itself. The threshold is the rigid track or lip at the base of the frame. Both work together. A damaged threshold may require frame repair in addition to seal replacement.
Do weather seals reduce outside noise? Yes, partly. Proper seals dampen wind noise and some traffic sound by blocking air gaps. They won't soundproof your garage, but they do reduce draft noise and whistling.
Will new seals help my heating bill? Absolutely. If your garage is attached to your home, drafts force your HVAC to heat unconditioned space. New seals reduce that waste significantly. Most homeowners see a 10 to 15 percent drop in winter heating costs after seal replacement.
