Your garage door's weather stripping and seals are doing heavy lifting you never notice. Until they aren't. A worn bottom seal lets cold air pour into your garage (and your home), and a failing threshold lets water and pests slip underneath. Replacement typically runs $150 to $400 depending on your door size and seal condition. The good news: it's one of the cheapest garage door fixes you can make, and it pays back fast through lower heating bills.
The Pacific Northwest climate is brutal on rubber. Rain, temperature swings from 30s to 60s, and constant moisture break down seals faster than in drier regions. Most weather stripping lasts 5 to 7 years before it hardens, cracks, or separates from the door frame. See our guide: Weather Stripping & Seals in Federal Way.
You'll notice signs before complete failure. Look for daylight creeping around the door edges when closed. Feel for draft at the garage floor. If you see water pooling inside after rain, or if pests have found a way in, your seals are compromised. Many homeowners catch these problems during routine maintenance checks, which is why we recommend inspecting your door at least twice yearly.
Replacement pricing depends on three factors: seal type, door size, and whether you're replacing just the bottom seal or the full perimeter. See our guide: Weather Stripping & Seals in Federal Way.
A simple bottom seal replacement (the most common job) runs $150 to $250. This is the rubber or foam strip at the base of your door that takes the hardest wear. Perimeter seals (top and sides) add another $100 to $200. If your threshold is also damaged, budget an extra $50 to $150 for that replacement.
Labor typically accounts for half the cost. The work itself is straightforward, but a technician needs to remove the old seal cleanly, measure precisely, and install new material to prevent drafts and water intrusion. A same-day service call for this repair is standard in Federal Way and the surrounding areas.

If you're losing heat through a bad seal, that loss compounds through winter. An uninsulated garage with a failing bottom seal can raise your heating costs by 10 to 15 percent. In Federal Way, where heating season stretches from October through April, that adds up.
Here's the math: if replacement costs $200 and saves you $30 a month in heating costs over six months, you break even by spring. After that, it's pure savings. Add in the fact that good seals keep water and pests out, and the return on investment becomes obvious.
This repair also pairs well with other seasonal work. If you're already scheduling garage door maintenance in Federal Way, adding seal inspection and replacement takes minimal extra time and maximizes your investment in door health.
Homeowners sometimes tackle this themselves to save money. It's possible, but there's a catch. Improper installation leaves gaps where drafts slip through, which defeats the whole purpose. Professional installation ensures seals fit snugly and last their full 5 to 7 years.
If you want a free estimate before committing, schedule a free quote and have a technician assess your door's actual condition. You'll know exactly what needs replacing and what the real cost is for your home.
A technician will inspect the entire door frame, not just the obvious problem area. They'll check the bottom seal first, then look at top and side seals, the threshold, and the door's alignment. Misaligned doors can't seal properly no matter how new the stripping is.
Replacement takes 30 to 60 minutes for a standard residential door. You'll be able to use your door immediately after. Modern weather stripping bonds quickly and doesn't require curing time.
Once new seals are installed, basic care extends their lifespan. Keep the door track clean of debris and water. In winter, clear ice and snow from the threshold and bottom edges. These simple steps reduce premature wear and keep your seals functioning longer.

Weather stripping and seals are small components that prevent big problems. A $200 replacement today stops $500 in water damage, pest control costs, or heating waste later. If your garage door is letting in drafts or water, don't wait for winter to worsen the problem.

How often should I replace weather stripping? Weather stripping typically lasts 5 to 7 years in Federal Way's wet climate. Inspect it annually and replace when you see cracks, hardening, or visible gaps.
Can a bad seal cause my heating bill to spike? Yes. A compromised bottom seal or threshold can increase heating costs by 10 to 15 percent during cold months by allowing warm air to escape into an unheated garage.
Is weather stripping replacement a same-day service? Most replacements are completed in 30 to 60 minutes. Call (253) 264-0137 to schedule same-day service if availability allows.
What's the difference between bottom seal and threshold? The bottom seal is rubber or foam attached to the door's lower edge. The threshold is a separate component on the ground where the door closes. Both prevent drafts and water intrusion.
Will replacing seals stop water from leaking under my garage door? A new bottom seal and threshold will stop most water intrusion. If water still leaks after replacement, the issue may be door alignment or grading around your garage. We'll diagnose the root cause during your estimate.
