Weather stripping and seals are your garage door's first line of defense against drafts, rain, and unwanted pests. After 15 years of service calls across Shady Cove and the surrounding areas, I can tell you straight: a worn threshold or deteriorated seal is one of the easiest problems to fix and one of the costliest to ignore. Let me walk you through what actually matters.
Your garage door has three critical seal points: the sides, the top, and the bottom. The bottom seal (also called a threshold) takes the most abuse. It compresses under the door's weight, flexes with temperature swings, and bears the brunt of water intrusion during our rainy Oregon winters.
When seals fail, cold air streams into your garage. That draft pulls conditioned air from your home, forcing your HVAC system to work harder. Moisture sneaks in too, inviting mold and rust on metal components. If your garage is attached to your house, you're also heating the neighborhood.
Weather stripping around the sides and top keeps the draft at bay. A good seal reduces energy loss by 10 to 15 percent on average. Over a heating season, that's real money back in your pocket.
Look for these red flags. Visible cracks or chunks missing from the rubber bottom seal are obvious. If you see daylight under the door when it's closed, you've got a threshold problem. Weatherstripping that's hardened, crumbling, or peeling away is past its service life.
Feel around the door frame in winter. Cold air leaking around the sides means the weatherstripping has lost its compression. Water stains or mold growth inside the garage are also telltale signs that moisture is winning.
Most weatherstripping lasts 5 to 7 years in Shady Cove's climate. The bottom seal often wears out sooner due to constant friction and exposure.
A full weather stripping and seal replacement typically runs between $150 and $400, depending on your door's size and condition. A bottom seal alone might be $75 to $200. These are ballpark figures; your actual cost varies based on material quality and labor.
The good news: this is one of the fastest repairs we do. Most jobs take under an hour. If you call us for a same-day estimate, we can often complete the work before you head to work the next morning. Same-day availability is standard for seal jobs in our area because they're straightforward and high-impact.

You can replace weatherstripping yourself if you're handy. The sides and top are forgiving. The bottom seal requires more precision because misalignment can cause binding or uneven wear on your door opener.
If your door is older or if you've noticed other issues, have a professional inspect it first. We've seen homeowners install a new seal only to discover the door frame is warped or the threshold bracket is rusted through. A proper diagnosis saves frustration and money later.

Shady Cove winters are wet and cool. A failing seal means moisture creeping in around your door, settling on metal springs and hinges, and accelerating corrosion. We've replaced corroded springs that might have lasted years longer if the seals had been intact.
Summer brings less dramatic wear, but summer heat can bake rubber seals, making them brittle. A seal that looked fine in July might crack and fail by October.

How often should I replace my garage door bottom seal? Every 5 to 7 years under normal conditions. Shady Cove's wet climate may shorten that timeline. Replace it sooner if you see visible cracks, hardening, or daylight underneath.
Can a bad seal damage my garage door opener? Yes. Moisture and draft can corrode springs, hinges, and electrical components. A failed seal invites rust that spreads throughout your door assembly over time.
What's the difference between weatherstripping and a bottom seal? Weatherstripping is the rubber or foam trim along the sides and top of your door. The bottom seal is a heavier-duty threshold that bears the door's full weight and blocks water from underneath.
Is weather stripping repair covered under warranty? Most new doors include seals. Replacement seals after that are typically not covered. Ask us for details on your specific door when you call for an estimate.
How long does a seal replacement take? Usually 30 minutes to an hour. Same-day service is available for most jobs in the Shady Cove area.
