Here's what most homeowners don't realize about weather stripping and seals: a deteriorating bottom seal or threshold doesn't just let in a little air. It creates a draft that forces your heating and cooling system to work 15 to 20 percent harder, and it invites moisture, pests, and seasonal weather damage into your garage and home. By the time you notice the problem, you've already lost money on your utility bills for months.
The good news? Replacing weather stripping and seals is one of the most straightforward maintenance tasks you can do, and it pays for itself quickly in Arlington's unpredictable Pacific Northwest climate.
Our region cycles through wet winters, dry summers, and everything in between. That temperature swing and constant moisture exposure breaks down rubber and foam seals faster than in stable climates. UV rays, salt air if you're near the coast, and simple age all contribute to seal degradation.
Most garage door seals are designed to last 5 to 8 years under normal conditions. In Arlington, expect them to need attention closer to the 5-year mark. The bottom seal takes the most abuse because it bears weight, flexes with every open and close cycle, and sits where rain pools and temperatures fluctuate wildest.
If you haven't had your door inspected in a year or two, the seals are likely compromised. You might not see obvious cracks, but small tears and compression loss create gaps that let cold air, moisture, and unwanted pests inside.
Your garage door has several seal points: the bottom seal, side seals along the vertical tracks, and top seals near the header. Each serves a different purpose.
The bottom seal is the workhorse. It compresses against the concrete threshold as the door closes, creating a tight seal. Over time, it hardens and loses its flexibility, leaving gaps. A failing bottom seal is usually the first culprit behind drafts and moisture problems.
Side seals run along the inside of the vertical tracks and catch wind-driven rain and air leakage. These often outlast the bottom seal, but they still need periodic inspection.
The top seal sits at the header and prevents leaks around the garage opening's highest point. This one matters less in single-story garages but becomes critical if you have living space above.

A complete weather stripping and seal replacement typically runs between $150 and $400, depending on your door's size and seal condition. It's one of the best-value maintenance investments you can make. If you're experiencing energy waste and moisture problems, this repair pays back its cost within one heating or cooling season.
Getting an accurate estimate requires a technician to inspect your door in person. Garage Door Arlington provides free quotes with no obligation. We'll check your bottom seal, threshold condition, and side seals, then give you a clear picture of what needs replacing and why.
If your door hasn't been serviced in years, you might also benefit from a broader maintenance check. Our garage door maintenance guide covers the full scope of what homeowners should monitor, and it pairs well with seal replacement.
Watch for these red flags: visible light coming through gaps around your closed door, drafts you can feel near the door, water pooling on the garage floor after rain, or a spike in your heating bill during winter. Some homeowners also notice bugs or rodents finding their way inside.
Don't wait for all these signs to appear. If it's been five years since your last seal replacement, schedule an inspection now. The Pacific Northwest's wet season is coming, and a failing seal invites moisture damage that's far more expensive to repair than seal replacement.
Our cold weather preparation guide offers additional context on seasonal door care and why seals matter most as temperatures drop.
You can replace bottom seals yourself if you're comfortable working with basic tools and following instructions. The material costs roughly $30 to $80. However, improper installation leaves gaps that defeat the purpose. A professional ensures the seal compresses evenly and creates a true weathertight barrier.
For side seals and top seals, professional installation is especially worthwhile because they're fiddly to align correctly. Garage Door Arlington handles all three seal types as part of our routine service offerings. Schedule a free quote to discuss your specific needs.
Weather stripping and seals are just one part of keeping your door running smoothly and protecting your home. Springs, cables, openers, and hardware all require attention too. If you're addressing seals, it's a good time to ask a technician about your door's overall condition.
Your garage door works year-round in Arlington's harsh weather. Keeping seals in good shape prevents cascading problems down the road. Don't let a small leak become water damage or energy waste.
Call Garage Door Arlington at (360) 282-0676 to get a same-day estimate for weather stripping and seal replacement. We'll inspect your door thoroughly and recommend only the work that actually needs doing.
How often should I replace garage door weather stripping? In Arlington's climate, plan on replacement every 5 to 8 years depending on exposure and use. More frequent inspection catches problems early and prevents moisture damage.
Can I replace just the bottom seal, or do I need to replace all seals at once? You can replace seals individually. Most homeowners start with the bottom seal since it fails first. Side and top seals can be addressed later if inspection shows they're still functioning well.
What's the difference between a bottom seal and a threshold seal? The bottom seal is the rubber gasket on your door itself. The threshold is the concrete or metal edge at the floor where the seal compresses. Both matter for a tight fit.
How long does weather seal replacement take? Most jobs take 30 to 60 minutes. Same-day service is available across Arlington if you call early in the day.
Will new seals reduce my heating and cooling costs? Yes, significantly. Homeowners typically see a 10 to 15 percent reduction in energy costs after seal replacement, especially during heating season.
