Weather Stripping & Seals in Norfolk, CT: Stop Drafts Before Winter
2026-05-04 7 min read
A customer called last Tuesday asking why cold air was pouring into her garage even though her door closed perfectly. After a quick inspection, I found her bottom seal had cracked and separated from the threshold. She'd been losing heat for weeks without realizing it. Weather stripping and seals are unglamorous parts of your garage door, but they're critical for energy efficiency, pest control, and comfort. If yours are worn or damaged, here's what you need to know.
Why Weather Stripping Fails
Garage door seals take a beating. Sun exposure, temperature swings, moisture, and constant compression wear them out over time. Most quality seals last 5 to 7 years before they start to crack or shrink. In Connecticut, where we go from scorching summers to freezing winters, that timeline can be shorter.
The bottom seal bears the most weight and wear. It compresses every time the door closes and expands when it opens. Salt spray from winter road treatment, debris, and UV rays all accelerate deterioration. Side seals and top seals degrade similarly, but less visibly.
You'll notice draft entering your garage, higher heating or cooling bills, or insects and rodents finding their way inside. These signs mean it's time to act.
Spotting Damage Early
Walk around your closed garage door on a sunny day. Look for gaps between the door and the frame where light shows through. Check the bottom seal for cracks, tears, or areas where it's pulled away from the threshold. Press on the seals with your hand. They should be firm but slightly flexible, not hard or crumbly.
If your door is over 7 years old and you've never replaced the seals, assume they need attention. I recommend a free inspection to confirm. Our team at Norfolk Garage Doors can assess the full picture and give you an honest estimate.
Types of Seals and What They Cost
There are three main areas to seal: the bottom, the sides, and the top. A bottom seal replacement typically runs $150 to $400 depending on door width and material. Side seals cost $100 to $250 each. Top seals are usually $75 to $200. Labor adds another $100 to $200 for same-day installation.
Don't cheap out on material. Rubber and silicone seals outperform vinyl. They stay pliable in cold weather and resist cracking. A quality threshold can run $200 to $500 on its own, but it protects your entire seal system and prevents water infiltration.

Installation and Maintenance
Installation is straightforward but needs precision. The threshold must be level, and the bottom seal must sit flush against it with no gaps. Side seals should align perfectly with the door frame. If they're off by even a quarter inch, drafts will find their way through.
After installation, check your seals seasonally. Before winter, make sure everything is compressed and seated properly. Preparing your garage door for fall includes seal inspection as a critical step. Remove debris from the tracks and threshold to avoid premature wear.
Regular maintenance costs almost nothing but saves hundreds in wasted energy. Wipe down seals with a damp cloth quarterly. If you spot minor cracks, a vinyl repair sealant can extend their life by a year or two. Once cracks are deep, replacement is the only fix.
Why Choose Professional Installation
I've seen homeowners try DIY seal replacement. Some succeed. Most don't. The threshold must be perfectly level, or water will pool and damage your door. The seals need to be cut precisely and installed without wrinkles or twists. Poor installation wastes money and leaves you with the same drafts you started with.

Frequently Asked Questions
How long do garage door seals last? Quality seals typically last 5 to 7 years in Connecticut's climate. UV exposure, temperature swings, and salt spray can shorten that lifespan. Regular inspection helps catch wear early before drafts become a problem.
Can I replace seals myself? It's possible but challenging. The threshold must be perfectly level, and seals need precise installation to prevent gaps. Professional installation ensures proper fit and warranty coverage on labor.
What's the difference between bottom seals and thresholds? The bottom seal is the rubber or silicone strip attached to the door itself. The threshold is the horizontal bar on the ground where the seal compresses. Both work together to block drafts and water.
How much does a seal replacement cost near me? Material ranges from $150 to $500 depending on seal type and quality. Labor typically adds $100 to $200 for same-day service. Call 1-860-981-0644 for a free estimate specific to your door.
Will new seals reduce my heating bill? Yes. Drafts around a garage door can account for 10 to 15 percent of home energy loss. New seals eliminate that draft and typically pay for themselves within one heating season.
