Most homeowners don't think about their garage door until something breaks. But your weather stripping and seals? They're quietly failing right now, letting cold air seep in and your heating dollars seep out. A damaged bottom seal or worn threshold can cost you hundreds in wasted energy each winter. The good news: fixing it is straightforward, affordable, and something we handle same-day here in New London.
Garage door seals take a beating. UV exposure, temperature swings, moisture, and constant opening and closing all wear them down over time. In New London, our winters are brutal. That freeze-thaw cycle is especially hard on rubber and vinyl seals. They crack, shrink, and lose their grip on the frame. See our guide on commercial garage doors in new london: heavy-duty solutions that last.
When seals fail, you're not just losing comfort. Drafts pull warm air from your home. Pests get easier access. Your HVAC system works overtime. Over a heating season, poor seals can add 10-15% to your energy bills. A bottom seal replacement costs between $150 and $400 depending on damage and door size. Compare that to the energy waste, and you're looking at payback in one or two winters.
We've been installing and repairing seals across New London and nearby communities for 15 years. The pattern is always the same: people wait too long, the damage spreads, and the cost goes up. Read about your spring garage door maintenance checklist for new london homeowners.
Your garage door has multiple sealing points. The bottom seal is the most critical. This rubber or vinyl strip runs along the base and compresses against the floor when the door closes. A worn bottom seal leaves a visible gap. You'll feel cold air, see daylight, or notice bugs getting in.
Side seals run vertically along the frame edges. Top seals sit where the door meets the header. All three wear out, but the bottom seal goes first because it bears the most pressure and contact with the ground.
Threshold seals are slightly different. These sit on the concrete floor itself and work with the bottom seal to create a complete barrier. If your threshold is cracked or missing, no amount of door sealing will stop drafts completely.

Look for these warning signs. Visible cracks or tears in the rubber. Gaps between the door and frame that you can see light through. Cold drafts in your garage even when the door is closed. Dust or debris buildup along the threshold. A musty smell (often mold from moisture getting in). Insects or spiders nesting near the door edges.
The easiest test? Close the door and shine a flashlight around the perimeter at night. If you see light, your seals are failing. Don't wait for January to figure this out.

A typical bottom seal replacement runs $200 to $350 in labor and materials for a standard residential door. Side seals add another $100 to $150 each. If your threshold is damaged, that's an additional $150 to $250. Full seal replacement on all points typically costs $400 to $600.
Get a free estimate before committing. We'll inspect all your seals, check the condition of the frame, and give you an honest assessment of what needs replacing versus what can wait another season.
Installation takes 1 to 2 hours depending on complexity. We remove the old seal (usually adhesive backed, sometimes fastened), clean the frame, and install new material with proper compression. Done right, seals last 5 to 7 years before needing replacement again.

You can buy bottom seal kits online for $30 to $80 and install them yourself if you're handy. The process is straightforward. Remove old material, clean the frame, measure twice, cut the new seal, and apply it.
But here's what we've learned on the trucks: most DIY installations fail within a year. People underestimate how critical proper compression is. They skip frame cleaning. They use the wrong adhesive. The seal peels away or doesn't sit flush, creating gaps.
A professional install guarantees the job is done right. We use commercial-grade materials, ensure proper compression, and stand behind the work. If something fails, we fix it.
Don't wait until November. Spring and summer are ideal times to inspect and replace seals. You're not in a rush, weather is cooperative, and we can usually get you scheduled within a few days.

Weather stripping and seals are small components that make a massive difference in comfort, energy cost, and home protection. Don't ignore them.
How often do garage door seals need replacing? Most seals last 5 to 7 years with normal use. In harsh climates like New London winters, they may need attention sooner. Check them annually for cracks or gaps.
Can I replace seals myself, or do I need a professional? DIY kits are available and affordable. However, improper installation often leads to gaps and premature failure. Professional installation guarantees proper compression and longevity, typically costing $200 to $350.
What's the difference between a bottom seal and a threshold seal? The bottom seal is attached to the door itself and compresses against the floor. The threshold seal sits on the concrete and works with the bottom seal. Both are needed for complete weather protection.
Will new seals reduce my heating bill? Yes. Worn seals can add 10 to 15% to heating costs over winter. New seals typically pay for themselves in one to two heating seasons through energy savings.
