Weather Stripping & Seals in Spanaway: How to Stop Drafts Before Winter

2026-06-15 7 min read

If you've noticed cold air seeping into your garage or energy bills climbing during Spanaway winters, worn weather stripping and seals are likely the culprit. A damaged bottom seal or deteriorated threshold lets drafts steal your heat, forcing your heating system to work harder. The good news: replacing weather stripping and seals is one of the most cost-effective upgrades you can make, and it delivers results you'll feel immediately.

Why Weather Stripping Fails in Spanaway

Our Pacific Northwest climate is tough on garage doors. Rain, temperature swings, and moisture create the perfect storm for rubber seals to crack and deteriorate. Most weather stripping lasts 5 to 7 years before it needs replacement. If your garage door was installed before 2019, chances are your seals are already past their prime.

The bottom seal takes the most punishment. It bears the weight of water pooling against it, flexes with every door cycle, and endures repeated temperature changes. When this seal fails, you lose the thermal barrier that keeps your space conditioned. Cold air rushes in. Moisture follows. Your garage becomes a drafty, damp liability.

Spanaway homeowners often overlook this issue until they feel the chill or notice water stains on the garage floor. By then, secondary damage may have already started. That's why catching worn seals early matters.

The Real Cost of Ignoring Poor Seals

A deteriorating bottom seal or threshold does more than let in cold. It invites moisture that can damage stored items, corrode tools, and create conditions for mold growth. If your garage is partially finished or houses sensitive equipment, the stakes are higher.

Energy loss is measurable too. Studies show that poor garage insulation and sealing can increase heating costs by 10 to 15 percent. Over a heating season in Washington, that adds up fast. Weather stripping and seals are inexpensive insurance against both comfort and cost.

Beyond comfort, there's the safety angle. A compromised seal can allow pests and rodents easier entry. It also reduces the structural integrity of your door's seal system, potentially affecting the door's ability to operate smoothly.

What to Look For in Your Own Garage Door

Start with a visual inspection. Open your garage door fully and look at the rubber seal running along the bottom. Is it cracked, flattened, or peeling away from the frame? Check the side seals and top seal too. Any gaps, discoloration, or hardened rubber is a red flag.

Next, do the daylight test. Close your garage door on a sunny day and look for light streaming in around the edges. If you see obvious gaps, your seals aren't doing their job. You should also feel along the threshold for drafts or moisture.

If you find problems, don't wait for spring. Winter in the Puget Sound region brings heavy rain and cold that will only worsen existing damage. Addressing it now prevents water damage and keeps your heating bills reasonable through January and February.

Professional Replacement vs. DIY

Some homeowners attempt to replace weather stripping themselves. It's tempting because the cost of materials seems low. However, proper installation requires precision. The seal must sit flush against the door frame, with no gaps or wrinkles. If it's installed even slightly off, drafts will still get through and the seal will wear unevenly.

Professional technicians have the right tools and experience to ensure a perfect fit. They'll also inspect the underlying frame for damage that you might miss. If the frame is warped or the door is misaligned, no seal will perform well until that's corrected.

Can I replace weather stripping myself? While it's possible, professional installation ensures a proper seal. Technicians have specialized tools and can spot frame damage or misalignment that affects seal performance. Improper DIY installation often results in gaps and premature failure.
