If you've noticed cold air sneaking into your garage or felt a draft around your garage door on a wet Chimacum afternoon, your weather stripping is probably shot. A worn bottom seal or threshold lets in rain, leaves, and heat loss that costs you real money on your energy bills. After 15 years on the trucks around Jefferson County, I can tell you this is one of the easiest maintenance items homeowners overlook, yet one of the most effective.
Living in Chimacum means dealing with rain, wind, and temperature swings that wear seals faster than you'd expect. Your garage door's weather stripping serves three critical jobs: it blocks water from pooling under the door, stops drafts from escaping conditioned air, and keeps pests and debris out.
Most homeowners think about insulation only after they notice their heating bill spike. That's backwards. A damaged bottom seal or worn threshold can leak as much heat as an uninsulated door. If you've already invested in insulation, skipping seal maintenance wastes that effort entirely. We've covered the energy side in detail in our post on garage door insulation in Chimacum and how R-value affects performance, but seals are just as critical.
The rubber compounds in weather stripping deteriorate from UV exposure, freeze-thaw cycles, and constant flexing. In our climate, you're looking at 5 to 7 years before most seals need replacement, sometimes sooner if your door opens and closes frequently.
Your garage door has seals in multiple locations, and each one has a job.
Bottom seal (or threshold): This is the workhorse. It takes the most abuse because it sits where water pools and the door flexes hardest during opening and closing. When this fails, water runs straight into your garage and cold air pours in underneath.
Side seals: Mounted on the vertical tracks, these prevent drafts and debris from entering along the door's edges. They're often overlooked but critical in high-wind areas.
Top seal: Located where the door meets the header, this one keeps rain from dripping down into the tracks.
Weatherstripping tape: Applied around the frame perimeter, this flexible seal bridges small gaps that solid seals can't reach.

You don't need a technician's eye to spot trouble. Look for these red flags: daylight visible under the door when it's closed, water pooling inside after rain, drafts you can feel with your hand, debris accumulation at the threshold, or visible cracks and hardening in the rubber itself.
One trick I use is the dollar bill test. Close the door on a dollar bill at various points along the seal. If it pulls out easily without resistance, that seal isn't sealing. Try this at the bottom, sides, and top. If you're failing the test in multiple spots, you've got a problem.
The cost to replace weather stripping is modest, typically ranging from $150 to $400 depending on your door's size and which seals need work. Compare that to heating bills, potential water damage, or pest intrusion. It's one of the best returns on a garage door maintenance dollar.
Some homeowners attempt seal replacement themselves. If you're handy and your door is older, you might manage it. However, modern sectional doors often require specific seal profiles matched to your door's make and model. Using the wrong seal creates gaps that defeat the purpose.
Our technicians at Garage Door Chimacum can assess all four seal types, source the right parts, and have you sealed up during a single visit. We'll also inspect your garage door maintenance schedule while we're there to catch other wear before it becomes costly.

Once new seals are installed, keep the tracks and bottom threshold clear of debris. Leaves, dirt, and standing water accelerate seal breakdown. A quick vacuum of the track every month during fall and spring adds years to your seals' life. In winter, avoid using rock salt near your garage door; it corrodes seals and hardware. Use sand or kitty litter for traction instead.
Also consider our garage door safety features overview to ensure your door's auto-reverse and photo eye work properly. A malfunctioning door that hesitates or stalls will stress seals unnecessarily.
Worn weather stripping and seals are fixable problems that shouldn't be ignored. The longer you wait, the more your energy costs climb and the greater the risk of water damage inside. If you're seeing daylight under your door or feeling drafts, call us at (360) 234-3537 for a same-day estimate. We'll get your garage sealed tight against Chimacum's weather.
How long do garage door seals typically last? Most weather stripping lasts 5 to 7 years in the Pacific Northwest climate. Freeze-thaw cycles and constant use accelerate breakdown. If your door is older than that and you're noticing drafts, seals are likely due for replacement.
Can I replace just the bottom seal, or do all seals need replacement? You can replace individual seals. However, if the bottom seal is worn, side and top seals are probably deteriorating too. We recommend inspecting all four during any service call and replacing them together for maximum efficiency.
What's the difference between a bottom seal and a threshold? The threshold is the stationary part attached to the concrete floor or frame. The bottom seal is the rubber strip attached to the door itself that rides on the threshold. Both work together; if either fails, your door won't seal properly.
How much does weather stripping replacement cost in Chimacum? Typical cost ranges from $150 to $400 depending on door size and seal complexity. We provide free estimates, so call (360) 234-3537 for an exact quote tailored to your garage door.
Will new seals help my heating bill? Yes, noticeably. A missing or damaged bottom seal can leak as much conditioned air as an uninsulated door. Replacing worn seals typically cuts heating costs by 10 to 15 percent, especially if your garage is conditioned or adjoins your home's living space.
