Weather Stripping & Seals in New London: Stop Drafts Before Winter
2026-06-29 7 min read
In our years serving New London, we've seen this problem again and again: homeowners lose heat and cool air through failing weather stripping and seals around their garage doors, then wonder why their energy bills climb. A worn bottom seal or deteriorated threshold can cost you 10 to 15 percent more per month in wasted conditioning. The good news? This is fixable, and it doesn't require replacing your entire door.
Why Weather Stripping Fails in New London
Our North Carolina climate isn't kind to rubber and foam. Summer heat softens seals. Winter cold makes them brittle. Spring and fall temperature swings stress the material year after year. Most weather stripping lasts four to six years before it needs replacement, depending on sun exposure and how often your door operates.
The bottom seal takes the hardest hit because it contacts the ground, absorbs moisture, and flexes every time the door opens and closes. If you see light under your garage door on a sunny day, that's a draft. If you smell outside air or feel temperature differences, the seal has failed.
What Happens When Seals Go Bad
A failing bottom seal doesn't just waste energy. It lets pests in. Moisture seeps into your garage and crawls into walls. In New London homes, this can lead to mold and wood rot that costs thousands to repair later. Your HVAC system works overtime. Your garage becomes an uncontrolled space instead of a buffer zone.
We've also seen water damage to stored items, rusted tools, and damaged boxes because homeowners didn't address a failing threshold seal early. This is why regular inspection matters. You can check your own door's condition in less than five minutes. Look at the rubber seal along the bottom and sides. If it's cracked, compressed, or missing pieces, it's time to act.
Types of Seals and What We Install
The bottom seal is the most critical component. It bears weight and endures constant friction. We use commercial-grade rubber that resists UV damage and stays flexible through temperature swings. The threshold itself should be solid aluminum or steel, not cracked or bent.
Side seals and top seals matter too. These prevent drafts along the frame and stop pests from entering at corners. Many homes in New London have gaps here because the original seals were installed poorly or have compressed over time. Our team inspects all three areas during a service call.
If your door is older, we also check the frame itself. Sometimes the door frame has warped, and even new seals won't seal properly until we shim or adjust the frame. This is why a proper estimate matters before you buy parts online.
How Much Does Weather Stripping Cost?
The cost depends on door size, seal type, and whether the frame needs adjustment. A basic bottom seal replacement runs 150 to 300 dollars. Adding side and top seals brings the total to 300 to 500 dollars. If the frame is warped or the threshold is damaged, expect 500 to 800 dollars. We can provide an exact estimate after inspection. See our garage door cost and pricing guide for more detail on what affects pricing.

When to Replace vs. Repair
If the seal is compressed but not cracked, sometimes cleaning and lubricating helps temporarily. But this is a band-aid. Real seals need replacement when they lose their shape. If you've had the same seals for five years, don't wait for them to fail completely. Replacing them proactively costs far less than handling water damage or paying extra on your heating bill all winter.
We recommend checking seals during your annual garage door maintenance in fall. This catches problems before the heating season starts. Addressing seals in September costs less stress and money than calling in December when everyone is busy.
DIY vs. Professional Installation
You can buy weather stripping kits online. Some homeowners install them successfully. But improper installation leaves gaps and defeats the purpose. If the bottom seal isn't seated correctly or the sides have an air leak, you're throwing money away.

Frequently Asked Questions
How long do weather stripping and seals typically last? Quality seals last four to six years in North Carolina's climate. UV exposure, temperature swings, and door use frequency affect lifespan. Inspect annually and replace as soon as they compress or crack.
Can I replace just the bottom seal, or do all seals need replacement? You can replace seals individually. However, if the bottom seal has failed, side seals are often failing too. We inspect all three areas and recommend a complete seal package for consistent performance.
Will new seals reduce my energy bills? Yes, noticeably. A good seal can reduce heating and cooling loss by 10 to 15 percent in garage spaces. In New London's climate, that translates to real savings over a heating season.
What's the difference between a threshold and a bottom seal? The threshold is the metal track at the base of the door. The bottom seal is the rubber gasket that sits on or in the threshold. Both must be in good condition for a proper seal.
