A customer called last Tuesday morning. His electric bill had jumped $40 a month, his garage felt like a wind tunnel, and cold air was pouring in around the door frame. I drove out, took one look at the bottom seal and threshold, and told him straight: his weather stripping was shot. Fifteen minutes later, he had his answer. Weather stripping and seals in Millville stop drafts, keep heating costs down, and protect your garage from moisture and pests. When they fail, you feel it in your wallet.
Most homeowners ignore their weather stripping until something forces their hand. A sagging bottom seal doesn't look like an emergency. But it is. Cold air rushes in. Heat leaks out. Your HVAC system works overtime. Pests slip through. Moisture collects on your cars and tools.
I've been on the trucks for 15 years in this area, and I can tell you: the difference between a sealed door and a failing one is roughly $30 to $50 per month in wasted energy during winter. That's $300 to $600 per heating season. A new bottom seal or threshold kit costs between $150 and $400 installed. The math solves itself in under a year.
Your garage door seals wear out because they're exposed to UV light, temperature swings, and friction every single day. In Millville's climate, with our cold winters and humid summers, rubber and foam deteriorate faster than most homeowners expect. Springs last 7 to 9 years with regular use. Seals? They typically need attention every 5 to 7 years, sometimes sooner if you open and close the door multiple times daily.
The bottom seal is the workhorse. It's the rubber strip that runs along the bottom edge of your garage door, making contact with the concrete threshold as the door closes. When it hardens, cracks, or sags, drafts win.
The threshold is the strip anchored to your concrete floor. It catches the bottom seal and creates a tight seal point. If your threshold is cracked or missing, no seal will work properly. Weatherstripping around the sides and top of the door frame prevents air infiltration at those points too.

Look for visible cracks or tears in the rubber. Run your hand along the bottom seal when the door is closed. If you feel gaps or the seal feels brittle, it's time. Notice cold air flowing in? That's a draft from a failing seal. If you see daylight under the door when it's fully closed, the seal has sagged.
Moisture in your garage, especially after rain or during humid months, signals a broken weather seal. Small insects or spiders getting in? That's often a seal issue, not a pest problem. And if your heating bill climbed without explanation, suspect your weather stripping before blaming your thermostat.
A basic bottom seal replacement runs $150 to $250 in Millville, depending on your door's width and the seal type. Side and top weatherstripping adds another $100 to $200. If your threshold needs replacing, expect $200 to $400 total. A full perimeter seal job with new threshold typically costs between $400 and $600 installed.

How long do garage door seals last? Most weather stripping lasts 5 to 7 years with regular use. In Millville's climate, UV exposure and temperature swings can shorten that. Inspect annually and replace at the first sign of cracking or sagging.
Can I replace the bottom seal myself? Yes, if you're comfortable with basic tools. The seal slides into a channel and is held by a retaining strip. However, getting the seal seated properly requires care. If it's misaligned, drafts will persist.
What's the difference between a seal and a threshold? The bottom seal is the rubber strip on your door. The threshold is the metal or rubber strip on your concrete floor. They work together to create a tight closure point.
Will new seals reduce my heating bill? Absolutely. In winter, a properly sealed door can cut heat loss by 15 to 25 percent in that zone. Over a heating season, that's real money back in your pocket.
Do I need to replace all seals at once? Not always. The bottom seal wears first and matters most. But if the side and top stripping are also failing, replacing everything at once is more efficient and cost-effective than multiple trips.
