Weather Stripping & Seals in Tenino, WA: Why Your Garage Door Leaks (And How to Stop It)

2026-05-26 7 min read

Most people don't think about their garage door until something fails. By then, water's already pooling on the concrete, cold air's pouring in, and you're wondering why your heating bill jumped $40 a month. The culprit is usually silent: worn weather stripping and seals. In Tenino's wet climate, this isn't a luxury upgrade. It's a necessity.

What Weather Stripping Actually Does

Weather stripping is the rubber or foam seal that runs along your garage door's edges, top, and bottom. The bottom seal (often called the threshold gasket) takes the most punishment. Every time your door opens and closes, it compresses against concrete. Rain, ice, and debris pile up against it. Over time, it cracks, hardens, and stops sealing properly.

When seals fail, three things happen simultaneously. Cold air drafts through, moisture seeps in, and small pests find easy entry. In Tenino, where annual rainfall exceeds 50 inches, a compromised bottom seal means standing water in your garage within weeks. That water leads to concrete deterioration, mold growth, and rusted tools or equipment stored inside.

I've seen garages turn into wet caves because homeowners waited six months too long. The damage compounds. A $150 seal replacement becomes a $3,000 concrete repair plus mold remediation.

Signs Your Seals Are Failing

Look for these warnings before problems escalate:

Visible cracks or gaps in the rubber itself. If you can see daylight under your closed door, the bottom seal is gone.

Water pooling inside after rain. Even a quarter-inch gap lets water in during heavy downpours.

Drafts you can feel when standing near the door on a cold day. Your heating system works overtime trying to compensate.

Pest droppings or insect activity near the garage floor. Rodents and insects exploit tiny openings that seals should block.

The rubber is hard or brittle. Squeeze it with your finger. Good seals compress and bounce back. Failed seals stay compressed or crumble.

Check your door monthly, especially heading into fall and winter. Tenino winters are mild compared to inland areas, but the constant dampness is harder on rubber than cold snaps are. If you spot issues early, you can schedule a same-day replacement before water damage spreads.

Types of Seals and When to Replace Them

Not all weather stripping is created equal. Your garage door likely has three seal zones: top, sides, and bottom.

Top and side seals typically last 5 to 7 years in Tenino's climate. They protect against wind-driven rain and drafts but don't bear weight.

Bottom seals wear faster. Expect 3 to 5 years before replacement becomes necessary. They compress under the door's weight and drag across debris on every opening.

Rubber seals cost less upfront but degrade faster in wet climates. Silicone or EPDM seals last longer and resist UV better, though the initial cost runs 20 to 40 percent higher. For Tenino homes, the longer lifespan usually justifies the upgrade.

Before you replace seals yourself, understand the real cost. A complete seal kit for a standard two-car door runs $80 to $200. Labor adds $150 to $300 depending on complexity. If your door's frame is damaged or misaligned, you'll need frame repair first. That's when you call Garage Door Tenino. A professional can assess whether the frame needs work before sealing it up.

Prevention and Long-Term Care

Seals last longer when you maintain them. Every three months, clear debris from the threshold area. Leaves, dirt, and small rocks accumulate in the bottom track and accelerate seal wear. A simple sweep takes five minutes and extends seal life by a year or more.

In fall, inspect your seals before heavy rain season hits. Tenino's October through March months are when moisture damage accelerates. Don't wait until January when water's already inside.

If your home sits in a low spot or near drainage issues, consider upgrading to a threshold seal with a built-in dam. These cost more but actively push water away from the door rather than just blocking it passively.

What Weather Stripping Costs in Tenino

A basic rubber seal replacement runs $150 to $400 installed, depending on whether you need top, side, or bottom seals. Full seal kits for all three zones cost $300 to $600.

If your frame is damaged or the door is misaligned, costs rise. Frame straightening can add $200 to $500. The good news: we handle all of it in one visit. Schedule a free quote today and stop guessing about your garage's draft problem.

Frequently Asked Questions

How do I know if my garage door bottom seal is bad? Look for visible cracks, hardened rubber, or gaps where daylight shows under the closed door. If water pools inside after rain or you feel cold drafts, the bottom seal has failed and needs replacement soon.

Can I replace weather stripping myself? Yes, if you're mechanically inclined and have basic tools. The process involves removing the old seal, cleaning the track, and installing new stripping. However, if your door is misaligned or the frame is bent, professional help prevents costly mistakes.

How long do garage door seals last? Bottom seals last 3 to 5 years in Tenino's wet climate. Top and side seals typically last 5 to 7 years. Silicone seals outlast rubber by 2 to 3 years but cost more upfront.

Why is my garage door letting water in? A compromised bottom seal is the most common cause. Wind-driven rain also enters through gaps at the sides or top. Have a professional inspect all three seal zones to pinpoint the problem.

What's the difference between rubber and silicone seals? Rubber is cheaper but degrades faster in wet climates. Silicone resists UV and moisture better, lasting longer with minimal maintenance. For Tenino homes, silicone usually saves money over time.
