A failing bottom seal or threshold lets more than just cold air into your garage. Water pooling on your floor, rodents finding shelter, and energy bills climbing month after month are real consequences I've seen in Westbrook homes. The fix is straightforward: inspect your weather stripping now, before winter hits hard.
Your garage door's weather stripping and seals work year-round to block drafts, moisture, and pests. They're rubber or vinyl strips running along the bottom, sides, and top of the door frame. Connecticut's freeze-thaw cycles are brutal on these materials. Temperature swings from 50 degrees to 20 degrees overnight cause rubber to crack and shrink. Sunlight degrades the material over time too. See our guide on preparing your garage door for hot weather: essential tips.
Most homeowners don't notice until something obvious breaks. A gap appears at the threshold. You spot water stains on the concrete floor after heavy rain. Your heating bill spikes 15 to 20 percent because conditioned air escapes through gaps. By then, the seal has already been leaking for weeks or months.
When your bottom seal deteriorates, you're not just losing energy. Water intrusion is the real danger. I've responded to calls where standing water in a Westbrook garage froze and cracked the concrete foundation. Repair cost: thousands of dollars. The weather stripping itself? Maybe $150 to $300 installed. Read about garage door price surprises westbrook homeowners miss.
Pests are another hidden problem. A quarter-inch gap at the threshold is an open invitation for mice, spiders, and insects. Once they're inside your garage, they move toward your home's interior. Pest control then becomes expensive. Rodents can also chew through wiring in your garage door opener, creating a safety hazard.
Energy loss compounds silently. A worn threshold seal means your HVAC system works harder to maintain temperature. Over a winter season in Westbrook, that draft can cost $200 to $400 in wasted heating. Over five years, that's $1,000 to $2,000 in unnecessary bills.
Check your seals quarterly, especially before winter. Look for visible cracks, peeling material, or sections that no longer make contact with the frame. If you can slide a credit card between the seal and door, it's time for replacement.
Run your hand along the bottom seal while the door is closed. You should feel a slight resistance. No resistance means air is moving. Open the door and inspect from inside the garage. Sunlight streaming in around the frame edges signals failing seals.
Water damage shows up as dark stains or rust spots on the concrete near the door. Moisture on the walls or musty odors are also red flags. These indicate your current seals aren't protecting against Westbrook's humidity and rain.

How long do garage door seals last? Most weather stripping lasts 5 to 7 years in Connecticut's climate. UV exposure, freeze-thaw cycles, and regular door movement accelerate wear. Inspecting annually helps you catch failure early before water or pests enter.
Can I replace just the bottom seal, or do I need the sides too? You can replace sections individually, but we recommend inspecting all seals at once. If the bottom is failing, the sides and top are likely wearing too. A complete seal job ensures consistent protection against drafts and water.
What's the difference between a threshold seal and a bottom seal? The threshold is the metal or rubber strip at the base of the door frame. The bottom seal attaches to the door itself and compresses against the threshold when closed. Both must work together to block drafts and water.
How much does weather stripping cost in Westbrook? Typical cost ranges from $150 to $400 installed, depending on door size and seal type. We provide a free estimate before starting work. Prices are much lower than emergency water damage repairs down the road.
Will new seals fix my drafty garage? Worn seals are the most common cause of garage drafts. If your frame is straight and the door closes fully, new seals will solve the problem. If the door won't close properly, the frame may be bent and require additional repair.
