Weather stripping and seals are the easiest way to stop cold air leaks around your garage door. A worn bottom seal or cracked threshold lets drafts in, drives your heating costs up, and lets pests inside. We'll walk you through what needs replacing and what actually makes a difference.
Your garage door is one of the largest moving openings on your home. When seals wear out.and they do, especially in Adna's damp Pacific Northwest climate.the gaps add up fast. A missing or damaged bottom seal alone can let in as much cold air as leaving a window cracked open all winter.
We're not just talking comfort here. That draft means your furnace works harder. Your heating bills climb. And moisture creeps in, which invites rust, mold, and rot. Over time, poor seals also let insects and rodents find their way into your space.
The good news? Replacing weather stripping is one of the cheapest preventive repairs you can make. A quality bottom seal, threshold, and side seals typically cost far less than fixing water damage or dealing with a failed opener later.
The bottom seal takes the most punishment. It compresses against your driveway or floor every time the door closes, and it's exposed to moisture, temperature swings, and UV light. Most bottom seals last 5,7 years before they harden, crack, or lose their seal.
A threshold is the metal or rubber strip at the base that helps the seal sit flush. Together, they create a tight fit. Without both working together, you've got gaps.
Your garage door also has seals running up both sides and across the top. These prevent air from sneaking in around the frame. Side seals are especially critical if your door is exposed to wind-driven rain.common in western Washington.
We typically recommend rubber seals over felt. Rubber lasts longer, handles temperature swings better, and resists moisture more effectively. Felt is cheaper upfront but degrades faster in our climate.

Look for these signs: visible cracks or hardening in the rubber, daylight showing under the door when it's closed, drafts coming from the bottom or sides, or water pooling inside after rain. If you're paying more to heat your garage than you used to, worn seals might be the culprit.
Check the threshold too. If it's bent, rusted, or no longer sits flush against the seal, air will leak around it. A threshold replacement often costs $100,$200 and pays for itself in energy savings within a season or two.
Bottom seals run $80,$200 installed, depending on material and door size. Thresholds add $50,$150. Full sealing (bottom, sides, top) typically runs $250,$400. That's honest pricing.no hidden fees, no upselling you on work you don't need.

Seals can be replaced any time, but late fall is ideal in Adna. Winter's coming, and a fresh seal means you're not wasting heat or dealing with ice buildup. We can often do same-day service if you call early in the week.
Installation takes 30,45 minutes. We'll remove the old seal carefully, clean the track and frame, and install new seals so they compress evenly. Proper fit matters.a seal installed loose won't do its job.
If your door has other issues.misaligned tracks or worn springs.those should be handled too. A worn seal can mask deeper problems. That's why we always recommend a full door inspection before sealing work.
Once new seals are in, they'll last longer if you keep them clean. Remove debris from the bottom seal quarterly. In winter, clear ice and snow so the seal compresses fully when the door closes.

How often do garage door seals need replacing? Bottom seals typically last 5,7 years in our climate. Side and top seals may last 8,10 years if the door is sheltered. Annual inspections help you catch wear early.
Can I replace weather stripping myself? You can replace some seals yourself if you're handy, but proper compression and alignment matter. Mistakes leave gaps. We recommend professional installation for lasting results.
Does weather stripping really save money on heating? Yes. A worn bottom seal can account for $10,$20 per month in lost heat during winter. New seals often pay for themselves in one heating season.
What's the difference between a threshold and a bottom seal? A threshold is the metal or rubber base piece; the seal is the compressible strip that rides on top. Both are needed to block drafts and water.
Should I seal my garage door before winter? Absolutely. Fall is the best time to replace seals before cold weather arrives. Call us in September or October to avoid the rush.
