A customer called last Tuesday complaining his garage felt like a freezer. He'd checked the door itself, springs looked fine, opener worked great. But cold air poured in around the edges like his garage door was wide open. The culprit? Deteriorated weather stripping and a failing bottom seal. This happens constantly in Chehalis and across Lewis County. When rubber and foam break down, you lose the thermal barrier your garage needs, your heating bill climbs, and moisture creeps in. Replacing weather stripping and seals is one of the cheapest fixes that actually moves the needle on comfort and energy waste.
Chehalis gets wet. We're talking 50+ inches of rain annually, plus freeze-thaw cycles every winter. That environment destroys rubber and foam seals faster than anywhere in the country. See our guide on security lighting: protecting your family.
Weather stripping on garage doors takes abuse. Sun, moisture, temperature swings, and constant compression from the door opening and closing all wear it down. Most quality stripping lasts 5 to 7 years before it cracks, hardens, or separates from the frame.
The bottom seal is the first casualty. That rubber gasket at the threshold compresses against the concrete floor thousands of times. Ice, salt residue, and standing water accelerate the decay. When it fails, water and drafts get in immediately. Read about material selection guide: what every homeowner should know.
Side seals and top seals fail more slowly, but they fail too. You'll notice gradual light showing through, increased dust inside, or a draft you can feel with your hand near the frame. These aren't emergency repairs, but they are real maintenance items that deserve attention.
Weather stripping and seals are affordable repairs. A basic bottom seal replacement runs $150 to $350 depending on door size and seal type. Side and top seals cost similar amounts, sometimes less if done at the same time. A complete seal job for all three perimeter areas typically lands between $300 and $600.
That price includes labor and materials. We can usually diagnose worn seals in under 15 minutes and provide a same-day estimate. If you need the work done that afternoon, we handle it quickly. Chehalis homeowners appreciate not waiting weeks for comfort and energy savings.
Quality matters here. Cheap adhesive-backed foam deteriorates within two years. We use compression seals and gaskets rated for Pacific Northwest weather. They hold up 5 to 7 years minimum with normal use.

You don't need perfect seals to function safely. A garage door operates fine with worn stripping. But you will waste money and lose comfort.
Replace weather stripping if you see daylight around the frame when the door closes. Check the bottom seal by getting down and looking across the threshold. If it's cracked, compressed flat, or torn, replace it immediately. Water damage inside accelerates from there.
If you're already planning a tune-up or addressing garage door maintenance in Chehalis, add seals to the list. It's logical timing and keeps everything on one service call.
Drafts around the sides and top are lower priority if they're minimal, but they waste heating energy. In Chehalis winters, blocking every draft saves real money month to month. If your heating bill climbs unexpectedly or you notice cold spots in the garage, failing seals might be the reason.
Installation is straightforward. Most seals come in kits with adhesive backing or screw fasteners. We remove the old material completely, clean the frame, and apply new seals according to manufacturer specs. The work takes 30 to 45 minutes for a full perimeter job.
For material, compression seals work best in wet climates. They compress slightly when the door closes, creating a tighter fit than rigid stripping. Foam backing is fine for insulation value, but rubber or silicone faces last longer against moisture.
Threshold seals come in several profiles. Some are U-shaped gaskets that slide into a base channel. Others are full-width rubber bars that glue directly to concrete. We recommend the channel style for durability. It costs a bit more upfront but performs better through multiple freeze-thaw cycles.

Worn seals are invisible until they fail completely. Most homeowners don't think about weather stripping until they notice a problem. That's fine, but don't wait once you see light or feel a draft.

Protecting your garage from weather and water is basic maintenance. Weather stripping and seals are cheap insurance against bigger problems down the road.
How often do garage door seals need replacement? Quality seals last 5 to 7 years in the Pacific Northwest. Cold snaps, rain, and UV exposure accelerate wear. Check them annually and replace when you see cracks, gaps, or light leaking through the frame.
Can I replace weather stripping myself? Yes. Adhesive-backed foam is easy to install if the frame is clean and dry. Rubber compression seals require more precision. If you're unsure about the fit or material choice, professional installation ensures proper sealing and durability.
What's the difference between a bottom seal and a threshold? A threshold is the metal or rubber base attached to the concrete floor. The bottom seal is the gasket that compresses against it. Both work together. Replacing just one won't fix a draft if the other is worn.
How much does weather stripping reduce heating costs? Sealing drafts around your garage door can lower heating costs 10 to 15 percent if the garage is insulated and conditioned. Unheated garages see less direct savings but still benefit from moisture protection and cleanliness.
Do I need to replace all seals at once? No. Replace the bottom seal first since it fails fastest. Side and top seals can wait until they show visible wear. Doing them together saves one service call and labor, so many homeowners prefer bundling the work.
