Serving White City, we see this problem again and again: homeowners lose hundreds of dollars in heating and cooling energy because their garage door seals have deteriorated. A damaged bottom seal or worn threshold lets cold air pour in during winter and hot air escape in summer. The good news? Weather stripping and seals are one of the cheapest fixes you can make, and replacing them yourself or hiring a pro costs far less than emergency spring repairs or a full door replacement.
Oregon's temperature swings and moisture create harsh conditions for rubber and foam seals. Your garage door bottom seal, side jamb seals, and threshold experience constant compression from the door's weight, UV exposure from sunlight, and freeze/thaw cycles that crack rubber over time.
Most seals last 5 to 7 years before they harden, crack, or separate from the frame. If you notice daylight creeping under your door or feel a strong draft when it's closed, your seals are done. This isn't a cosmetic issue. A gap as small as a quarter-inch wastes energy and invites pests and moisture into your garage.
Look for these red flags. Visible cracks or chunks missing from the bottom seal mean it's time. If your garage feels significantly colder than adjacent rooms in winter, drafts are the culprit. You might also notice water pooling inside after rain or snow melt, which happens when the threshold seal no longer blocks moisture.
Some homeowners ignore minor gaps, thinking they'll save money. They don't. A draft that lets in cold air forces your furnace to work harder, raising your heating bill by 10% to 15% over a season. That's real money. Replacing seals costs a fraction of those wasted energy dollars.

Your garage door uses three main seal types. The bottom seal, or astragal, runs the width of the door and takes the most abuse. Replacement typically runs $75 to $150 for materials and labor if you hire a pro. Side jamb seals line the vertical tracks and cost $40 to $80 each. The threshold, which sits on the ground under the door, ranges from $100 to $200 depending on material and condition.
If you're handy, you can buy DIY seal kits for $30 to $60 and install them yourself, though the job requires patience and attention to detail. Many homeowners find it worth paying a technician to ensure proper fit and prevent leaks. Either way, the cost is manageable compared to other garage door repairs. For context, spring replacement or opener repair can run $200 to $400 or more.
The first step is a free inspection. A technician will look at the condition of your current seals, check for gaps or damage, and measure your door to confirm seal dimensions. This usually takes 10 to 15 minutes. From there, you get a clear estimate for parts and labor. Don't be surprised if the tech recommends replacing all seals at once, even if only one shows obvious wear. Partial replacement often leaves gaps that undermine the whole system.
When comparing costs, ask what type of seal material is included. Budget rubber lasts 5 years; reinforced rubber or vinyl might last 7 to 9 years. The price difference is small but affects long-term value.
If your door has other issues, like a worn spring or opener trouble, seals might be part of a larger tune-up. Check our guide on garage door maintenance in White City to see if other components need attention.
Replacing seals yourself saves labor costs but demands precision. The bottom seal must sit flush against the ground with no gaps at the corners. If you install it crooked, drafts will return. Side seals require proper alignment with the tracks. One mistake means moisture gets in and defeats the purpose.
Hiring a technician guarantees correct installation and often includes a warranty on the work. Many homeowners find this peace of mind worth the $100 to $200 labor fee. If you're not confident with tools or your door is older and needs careful handling, professional installation is the smarter choice.

How often should I replace garage door seals? Most seals last 5 to 7 years depending on climate and use. White City's freeze-thaw cycles can shorten that to 4 to 6 years. Replace them sooner if you see visible cracks, daylight under the door, or water seeping inside.
Can I replace just the bottom seal and leave the side seals alone? You can, but it's often not ideal. Side seals degrade at similar rates, and replacing only one seal leaves gaps elsewhere. A complete seal replacement ensures consistent protection and better energy efficiency across the whole door frame.
What's the difference between a threshold and a bottom seal? The threshold is the metal or rubber strip that sits on the ground and blocks the gap between door and concrete. The bottom seal is the rubber gasket attached to the door itself. Both work together to stop drafts and moisture. Ideally, replace both when one fails.
Will new seals fix my heating bill? Seals won't fix all energy loss, but they address one major source. A gap around your garage door lets heated air escape and cold air enter. Replacing worn seals typically reduces heating costs by 8% to 12% if your door was severely drafty.
How long does a seal replacement take? A professional can replace all seals in 30 to 45 minutes. DIY installation may take 1 to 2 hours if you're working carefully and this is your first time. Rush the job and you'll likely end up with poor results.
