A customer called last Tuesday morning. Her garage was noticeably colder than the rest of her Salisbury home, and she could see daylight peeking under the door. That gap along the bottom seal wasn't just letting in cold air. It was bleeding her heating budget and letting moisture, pests, and exhaust fumes into her home. Weather stripping and seals fail silently, and by the time you notice, you've already paid hundreds in wasted energy.
Garage door seals take a beating. Every time your door cycles up and down, the rubber bottom seal compresses, stretches, and flexes. In Salisbury's climate, we see freeze-thaw cycles that crack seals in ways you won't detect until a draft becomes obvious. Most residential bottom seals last 5 to 7 years before they harden, crack, or separate from the door itself.
The threshold seal (that rubber strip where the door meets the concrete) wears even faster because it absorbs the full impact of temperature swings and moisture. I've seen thresholds deteriorate in 3 to 4 years if they weren't installed correctly the first time.
What makes this worse is that you keep paying the cost long after the seal fails. A failed bottom seal or threshold allows warm air to escape during winter and cool air to leak out during summer. That translates to roughly $40 to $60 per month in wasted heating and cooling costs for an average Salisbury home.
Look for these red flags before the draft becomes a crisis:
Visible cracks or peeling rubber. If the bottom seal is visibly cracked or peeling away from the door, replacement is overdue. Same goes for a threshold that's curled, hardened, or separating from the concrete.
Daylight under the door. Stand inside your garage on a sunny day. Can you see light creeping in around the edges or along the bottom? That's a gap your seals can't close anymore.
Temperature swings in the garage. Your garage should stay reasonably close to outdoor temperature if it's unheated, but a failed seal creates dead spots where cold pools or where pests find easy entry.
Pest activity near the door. Rodents, insects, and spiders use gaps under garage doors to access your home. If you're seeing more activity near the garage entry, inspect your seals immediately.
I once visited a home in Concord where the homeowner had been dealing with mice for months. The real culprit was a deteriorated bottom seal creating a quarter-inch gap. A $200 seal replacement solved a $1,500 pest control problem.
People often ask about the cost for a repair. A standard bottom seal replacement typically runs $150 to $300 for materials and labor, depending on your door's size and condition. A threshold seal costs another $100 to $200. Same-day service is usually available if you call early.

We use commercial-grade materials that resist UV damage and temperature cycling better than budget alternatives. Your replacement seals should last 7 to 9 years with proper installation, not 3 to 4.

The sooner you seal those gaps, the sooner you stop paying for wasted heat. Seal failure is one of the easiest garage door repairs to put off because it doesn't stop your door from opening and closing. But the cost of doing nothing adds up quietly every single month.

How do I know if my bottom seal is bad? Look for cracks in the rubber, daylight under the door when closed, or a visible gap between the seal and the concrete floor. You might also feel cold drafts or notice energy bills rising. If you can see any of these, replacement is needed soon.
Can I replace weather stripping myself? Bottom seals require the door to be secured and lifted slightly to remove the old seal and slide in a new one. Without proper tools and training, you risk the door falling or pinching your hands. Professional installation ensures safe, watertight results.
How long do garage door seals last? Bottom seals typically last 5 to 7 years in Salisbury's climate. Thresholds wear faster, often lasting 3 to 4 years. Regular maintenance extends lifespan, but replacement is inevitable with normal use.
What's the difference between a bottom seal and a threshold? The bottom seal is the rubber strip attached to the bottom of the door itself. The threshold is a separate seal strip mounted on the concrete floor where the door closes. Both are needed for a tight seal.
How much does weather stripping replacement cost? A complete bottom seal and threshold replacement typically costs $250 to $500 for materials and labor. Most jobs qualify for same-day service. Call (980) 447-6193 for a free estimate with no obligation.
