A worn bottom seal or deteriorated weather stripping lets drafts in, water leaks through, and your heating and cooling escape. The fix is straightforward: replace the damaged seal or stripping before the problem spreads to your door frame or garage interior. Most Arlington homeowners can have this done same day.
Your garage door isn't just an entry point for your car. It's part of your home's thermal envelope. When the rubber seal at the bottom of your door cracks, splits, or hardens, cold air pours in during winter. Rain and snow seep into the garage. Summer humidity finds its way past a failed threshold seal and into your walls. Over time, moisture damage becomes expensive.
Weather stripping runs along the sides and top of the door frame. The bottom seal is the workhorse, absorbing impact every time your door closes. Both wear out at different rates depending on your climate and door cycle frequency. In Arlington, where we see rain, cold snaps, and occasional snow, seals typically last 3 to 5 years before they need replacement.
The draft you feel isn't just uncomfortable. It's money walking out of your garage. A compromised seal can increase your heating or cooling costs by 10 to 15 percent over a heating season. That adds up fast.
Look for visible cracks or gaps in your bottom seal. If you see daylight under the door when it's closed, the seal has failed. Run your hand along the rubber stripping on the sides and top. If it feels hard, brittle, or crumbly instead of flexible, replacement is overdue.
Water pooling in your garage after rain is another red flag. So is a musty smell near the door frame. Both indicate that moisture is getting past your threshold and settling in the concrete or drywall.
Some homeowners notice their garage feels noticeably colder or hotter than it should. If your door opener seems to work harder, or if you hear more wind noise than before, worn seals are likely the culprit. When to repair versus replace is outlined in detail here, but the short answer is: if the seal is visibly damaged, replace it.

A bottom seal replacement typically runs between 150 and 300 dollars, depending on your door size and seal material. Side and top stripping adds another 100 to 200 dollars. Full weatherization (all seals plus threshold) usually lands between 300 and 500 dollars.
These numbers are industry standard for the Arlington area. The work takes 30 to 60 minutes. You can schedule a free estimate to get an exact price for your door. Bring photos or measurements of your current seal condition if you'd like a quote before we visit.
The cost difference between a basic rubber seal and a premium compression seal is usually 50 to 100 dollars. Premium seals last longer and compress more effectively against the door frame, which means better draft prevention and water shedding. For Arlington's wet climate, the upgrade often pays for itself in energy savings and reduced moisture damage.
At Garage Door Arlington, we measure your door frame, verify the seal type your door uses, and install the correct replacement. We don't guess. Mismatched seals create gaps and fail prematurely.
We stock the most common seal profiles for same-day installation. If your door uses a specialized profile, we order it and schedule your replacement within 24 to 48 hours. Either way, you're not waiting weeks.
After installation, we test the door's operation and inspect the seal under load to confirm it's making full contact with the frame. A seal that doesn't compress evenly won't perform, and we won't leave your job until it's right.
Our full service menu and capabilities are here. Whether you need just the bottom seal or a complete weatherization overhaul, we've got you covered.
A tiny gap feels minor until November hits and your heating bill spikes. Water damage starts small, too, then spreads into framing and insulation. Catching seal failure early prevents bigger, costlier repairs down the road.
If you spot cracks, gaps, or hardness in your weather stripping or bottom seal, call us at (360) 282-0676 or get a same-day estimate online. We'll inspect your door, tell you exactly what needs replacing, and give you a firm price before we touch anything. Same-day service is available for most Arlington locations.
Your garage door should seal tight and operate smoothly. A worn seal does neither. Let's fix it.
How long do garage door weather seals last? Most rubber seals last 3 to 5 years in Arlington's climate. Compression seals and premium materials can extend that to 7 years. Regular inspection catches failure before water damage starts.
Can I replace weather stripping myself? Yes, if you're handy. Stripping pulls out of the frame groove. New stripping slides in and snaps into place. Bottom seals require more precision to align correctly and ensure full contact under load. Professional installation guarantees the job is done right.
What's the difference between a bottom seal and threshold stripping? A bottom seal is the rubber piece attached to the bottom edge of your door itself. Threshold stripping sits in the frame opening below the door. Both seal the gap, and both wear out. A complete seal requires replacing both.
Will new seals reduce my energy bills? Yes. A failed seal can increase heating or cooling costs 10 to 15 percent. Replacing it typically recovers that loss within one heating season, depending on usage and local energy prices.
How do I know if my seal is beyond repair? If it's cracked, split, hardened, or missing chunks, it needs replacement. Small cracks can sometimes be sealed temporarily, but a full replacement is the permanent fix. We'll assess the condition during your free estimate.
