Your garage door stays closed most of the time, so you might not notice when its weather stripping & seals start failing. But by the time you see drafts or feel cold air seeping in, the damage is already costing you money. Here's what to watch for before a small problem becomes expensive.
The bottom seal takes the worst beating. It drags across your driveway thousands of times per year, exposed to UV rays, moisture, and temperature swings that Burlington winters throw at it. If you see cracks, tears, or chunks missing from the rubber, replacement is overdue. See our guide on essential garage door maintenance tips for homeowners.
Look for gaps between the seal and the ground when the door closes. In summer, this might seem harmless. But come November through February, that gap becomes a highway for cold air, moisture, and pests. I've seen homeowners ignore small tears, only to find their heating bill jumped $80 to $120 per month because warm air was escaping constantly.
The threshold seal matters just as much. This sits at the base of the door frame and catches water before it pools inside. When it cracks or compresses (losing its shape), water runs straight into your garage during our Pacific Northwest rainy season. Damage to stored items, vehicle rust, and mold growth follow quickly.
Most people don't think about their garage door until it stops working. But weather seals are working (or failing) every single day. A small draft doesn't announce itself loudly. You might notice the garage feels a bit chilly, or you see condensation on windows on cold mornings. By that point, the seal has been leaking for weeks.
Moisture is the real danger. Our region gets 45 inches of rain annually. If your weather stripping is compromised, water seeps into the garage, the door frame, and the wall cavities behind it. Mold grows in darkness and damp. Wooden door frames rot from the inside out. Once rot sets in, you're not just replacing a $200 seal anymore; you're looking at frame replacement that costs thousands.
Check your door's side seals and top seal too. These are easy to forget. They don't touch the ground, so they seem less critical. Wrong. Side seals prevent wind-driven rain from entering during storms. The top seal stops water from pooling on top of the door and running down the sides. If either is peeling, cracked, or missing, you need replacement.

Weather seal replacement is one of the cheapest preventive repairs you can make. A bottom seal replacement typically costs between $150 and $300, depending on door size and material. A complete seal package (bottom, sides, top, and threshold) ranges from $350 to $600. Compare that to repairing water damage or replacing a rotted frame, and the math is obvious.
The best time to address this is before winter. Once rain and freeze cycles begin, damaged seals let water into cracks. That water freezes, expands, and splits wood or metal further. By spring, a $250 repair has become a $2,000 frame replacement. Garage Door Burlington sees this pattern every year.
If you're unsure whether your seals need replacement, don't wait for the problem to announce itself loudly. A free visual inspection takes 10 minutes and gives you a clear answer. We can provide an estimate on the spot and schedule same-day service if needed. Our technicians have seen every failure mode, so we catch problems most homeowners miss.

Some homeowners try DIY seal replacement. The work itself isn't complex, but getting the fit right matters. An improperly installed seal leaves gaps that defeat the purpose. You also risk injury if the door is spring-balanced and you're working near the springs.
Professional installation guarantees proper fit and function. Our team aligns seals perfectly, tests them under load, and ensures water runs away from your garage instead of into it. Visit our weather stripping & seals service page to see what's included.
Don't let small signs become big problems. Cracked seals, visible gaps, drafts, or condensation all warrant action. Schedule a free quote today or call 360-637-1592. Same-day service is available for most Burlington-area addresses. Catching this early saves thousands in water damage and heating bills over the next few winters.
A functioning weather seal system protects your garage, your vehicle, and your home's foundation. It's one of the simplest investments you can make in weatherproofing your property.
How long do garage door weather seals last? Most rubber seals last 5 to 8 years depending on sun exposure, temperature swings, and maintenance. Pacific Northwest conditions age them faster due to moisture and UV rays.
Can I replace weather stripping myself? Yes, but fit and alignment are critical. Improper installation leaves gaps that defeat the seal's purpose. Professional installation ensures watertight performance and proper door operation.
What's the difference between a bottom seal and a threshold seal? A bottom seal attaches to the door itself and moves up and down. A threshold seal sits stationary at the base of the door frame. Both prevent water and drafts from entering your garage.
Will replacing seals reduce my heating bill? Absolutely. Drafts account for 15 to 25 percent of heating loss in garages with damaged seals. Replacing them can lower winter utility costs by $50 to $150 monthly depending on door size and usage.
How do I know if my seals need replacement soon? Look for visible cracks, tears, missing chunks, peeling edges, or gaps when the door closes. Also check for drafts, condensation, or water pooling inside. Any of these signs means replacement is due within weeks.
