Here's what most homeowners don't realize about weather stripping and seals: by the time you feel a draft in your garage, the damage is already months old. I've seen homeowners in Westport and throughout Pacific County lose hundreds of dollars in heating costs because they waited for a visible problem. The bottom seal and threshold wear silently, and cold air sneaks in long before you notice the temperature drop. Knowing when to replace your weather stripping and seals can save your energy bill, protect your home's foundation, and prevent water damage that costs far more to fix later.
Your garage door's weather stripping and seals face constant punishment. Rain, freezing temperatures, UV exposure, and the simple friction of opening and closing wear these materials down year after year. In Westport's damp climate, rubber and foam seals degrade even faster because moisture accelerates breakdown.
Most homeowners assume their seals will last as long as the door itself. They won't. A quality bottom seal typically lasts 5 to 7 years before noticeable wear appears. Threshold seals, which bear more weight and flex more often, may fail sooner. Once deterioration starts, it accelerates quickly because damaged seals allow water inside, which softens the underlying wood and metal components.
The cost of ignoring this is real. Mold growth in your garage, rust on the door tracks, warping of the door frame, and energy loss can add up to $2,000 or more in repairs. A simple seal replacement costs a fraction of that and takes hours, not days.
Walk around your closed garage door and look at the bottom seal and threshold. Can you see light coming through? Are there cracks, splits, or chunks missing from the rubber or foam? If yes, that seal is no longer protecting your garage. Even small gaps let drafts slip through and invite water inside during rain.
Feel around the edges of your closed door on a cold day. Cold air should not be flowing in. If you detect a noticeable draft near the bottom or sides, your seals have failed. This is one of the first signs homeowners notice, and it's a clear signal that replacement is overdue.
Water pooling along the garage floor where the door meets the threshold means your bottom seal isn't doing its job. Stains on the concrete or on the lower door panels indicate water has been entering for some time. This damage spreads fast in Westport's rainy climate and can compromise the structural integrity of your garage door opening.
Push gently on the seal material. Quality seals should be flexible and slightly firm. If the rubber feels hard, crumbly, or brittle, it has lost its elasticity and can no longer create a tight fit. This is a material degradation issue and means replacement is necessary.
Dark spots, green growth, or unusual discoloration on the seal itself or on the door frame nearby indicate moisture has been trapped there. This means water is getting past the seal regularly. Mold growth is both a sign of seal failure and a health concern for your family.

I've seen homeowners put off seal replacement for months, thinking "it's just a draft." Then the door frame starts to rot. Then the garage becomes a moisture problem. Then the entire door operation becomes compromised because water has corroded the springs and tracks. What started as a $300 seal job becomes a $2,500 door replacement.
Your garage door is one of the largest moving parts of your home. It protects your vehicles, tools, and whatever else you store inside. The weather stripping and threshold are the first line of defense against water, pests, and energy loss. When they fail, everything downstream suffers.

A bottom seal replacement typically costs between $200 and $500, depending on the door size and material quality you choose. If your threshold also needs work, add another $100 to $300. Most jobs take 2 to 3 hours. Compare that to the cost of water damage repair, mold remediation, or a full door replacement, and the decision becomes clear.

How often should weather stripping be replaced? Every 5 to 7 years for bottom seals under normal conditions. In Westport's wet climate, inspect annually and replace sooner if you notice wear, cracks, or water damage.
Can I replace weather stripping myself? The bottom seal and threshold can be DIY projects if you're mechanically inclined. However, side seals and top seals require careful alignment. Improper installation leaves gaps that defeat the purpose. Professional installation ensures a tight fit.
What's the difference between bottom seal and threshold? The bottom seal is the rubber or foam strip attached to the door itself. The threshold is the raised barrier on the floor or frame. Both work together to keep water and drafts out. Both may need replacement.
Will new seals reduce my heating costs? Yes. A leaking seal lets conditioned air escape. Replacing failed seals can reduce energy loss by 10 to 20 percent, depending on how bad the damage was. You'll notice savings within the first month.
What type of seal material lasts longest? Rubber and reinforced vinyl seals last longer than basic foam. Garage Door Westport installs high-grade materials rated for 7 to 10 years. Ask about options when you request your free estimate.
