If your garage feels drafty, your energy bills are climbing, or you've noticed pests sneaking in around the door frame, your weather stripping and seals are likely worn out. The good news: this is one of the most cost-effective repairs we handle at Glenville Garage Doors, and it makes a real difference in comfort and utility costs.
Weather stripping is the rubber or foam seal that runs around the perimeter of your garage door. The bottom seal (sometimes called the threshold) is the most critical piece. Together, these seals create an airtight barrier between your garage and the outside world.
In Glenville and across the Western NC mountains, we deal with four distinct seasons. Winter temperatures can drop below freezing, and summer humidity is relentless. Your garage door seals take a beating from temperature swings, UV exposure, and moisture. Most weather stripping lasts 5 to 7 years before it hardens, cracks, or separates from the frame.
When seals fail, cold air drafts into your garage. If that space is attached to your home, you're heating or cooling the outdoors. You'll also notice insects, rodents, and moisture finding their way inside. That's when people call us.
Look for these red flags. Visible cracks or gaps in the rubber are obvious. If you can see daylight around the bottom seal when the door is closed, it's time for service.
Run your hand along the frame on a cold day. Feel a draft? That's air escaping through damaged stripping. Another clue: if your garage stays noticeably colder than it should, or if you're finding spider webs and insects more often than usual, seals are the culprit.
We also recommend inspecting seals during spring preparation, which we covered in detail in our spring preparation tips guide. Seasonal shifts expose seal damage that winter weather masked.

I won't pretend weather stripping repair is glamorous, but I will be straight with you about cost. A bottom seal replacement runs between $150 and $350 depending on your door size and material. Side and top seals add another $100 to $200 per section if needed.
Compare that to what you'll spend on wasted heating and cooling over a year. Most homeowners recoup the cost within 12 to 18 months through lower utility bills. That's real money in your pocket.

The bottom seal gets the most wear. It compresses under the weight of the door, flexes with temperature changes, and takes impact from debris on the garage floor. If water pools near your threshold or you see moisture damage on stored items, the bottom seal has failed.
Replacing just the bottom seal is usually faster and cheaper than replacing the entire seal assembly. That said, if your door is older, we often recommend replacing all seals at once. It's more efficient and ensures even protection.
You can buy weather stripping kits online for $30 to $80. Some homeowners attempt DIY replacement. Here's my honest take: if you're handy and patient, you might succeed. But most people underestimate the fussiness of proper installation.
Seals must sit flush with the frame. If they're misaligned, drafts persist. The adhesive or fasteners must be correct for your door material. Install it wrong, and you'll waste time and money.
Our team has installed hundreds of seal systems. We know the quirks of each door type. We get it right the first time, and we stand behind our work. View our full weather stripping service details to see what's included.
The mountains of Western North Carolina present unique challenges. Humidity swings are dramatic. Spring and fall bring heavy moisture. Winter ice and snow put extra stress on seals. Summer heat can warp frames if seals don't provide proper insulation.
That's why we see seal failure more often here than in flatter parts of the state. It's not a defect in your door. It's the environment. Planning for seal maintenance every 5 to 7 years is just smart ownership in this region.
Worn weather stripping and seals are costing you money every single day. Drafts mean wasted energy. Gaps mean pests and moisture. The fix is affordable, fast, and effective.

Don't let another season go by with a leaky garage door. Let's seal it up right.
How long does weather stripping last? Quality weather stripping typically lasts 5 to 7 years in our climate. Extreme temperature swings, UV exposure, and moisture accelerate wear. Inspect seals annually and replace when you notice cracks, hardening, or visible gaps.
Can I replace weather stripping myself? Yes, but it's tricky. Seals must be perfectly aligned and properly adhered. Misalignment defeats the purpose. Most DIY attempts result in drafts persisting. Professional installation ensures the job is done right the first time.
What's the difference between a bottom seal and side seals? The bottom seal (threshold) bears the door's weight and compresses constantly. Side seals prevent lateral drafts and pests. Top seals catch water runoff. All three matter, but the bottom seal fails first and impacts comfort most.
How much does weather stripping replacement cost? Bottom seal replacement runs $150 to $350. Adding side and top seals costs $100 to $200 per section. We provide free estimates. Most owners recoup costs within 12 to 18 months through energy savings.
Will new seals reduce my energy bills? Absolutely. Seals prevent conditioned air from escaping and outside air from entering. In our mountain climate with four distinct seasons, proper seals reduce heating and cooling costs by 10 to 15 percent, depending on your system and usage.
