Weather stripping and seals keep cold air, pests, and moisture out of your garage. When they fail, your heating bill climbs fast. Most Mount Holly homeowners don't realize their drafts come from worn seals, not poor insulation. Here's what actually happens and how to fix it right.
Your garage door's bottom seal, threshold, and side seals take a beating. They compress and decompress thousands of times per year as your door opens and closes. UV exposure from our North Carolina sun hardens the rubber. Temperature swings between cold mornings and hot afternoons crack the material. Salt air from nearby regions also accelerates breakdown.
Most seals last 5 to 7 years before they stop creating an effective barrier. If you've never replaced them, they're probably due. A damaged bottom seal lets cold drafts in during winter and lets your air conditioning escape in summer. That's money leaving your garage.
Walk around your garage door on a clear day. Look for light coming through gaps at the bottom, sides, or top. Run your hand near the frame. Feel a draft? That's your seal system failing. You might also notice:
Visible cracks or peeling in the rubber seal material. Gaps wider than a quarter inch between the door and frame. Daylight visible under the door when it's fully closed. Increased pest activity or unexplained drafts inside your garage.
If you're seeing these signs, don't wait for winter to hit. A small draft becomes a big problem when temperatures drop.
Your garage door uses three seal systems working as a team. The bottom seal is the workhorse, taking the most impact and wearing out fastest. The threshold sits under the door and seals the gap where the door meets the concrete floor. Side seals run vertically along both edges and prevent lateral air leaks.
All three must work together. A perfect bottom seal won't help if your threshold is cracked. Our team at Garage Door Mount Holly replaces all three when needed, not just the visible problem. That's the difference between a temporary fix and a real solution.

Pricing depends on which seals need replacing and your door's condition. A bottom seal replacement typically runs between $150 and $300. Adding side seals or a new threshold pushes the cost to $300 to $500. Full seal replacement on an older door might reach $600 to $800.

Delaying seal work costs more later. Drafts force your HVAC system to work harder, raising your energy bill by 10 to 15 percent during winter. Over a season, that's $200 to $400 in wasted heating costs. A $300 seal replacement pays for itself in energy savings alone.
Some homeowners try replacing seals themselves using kits from hardware stores. The materials cost $30 to $60. But removing old seals cleanly takes skill. Improper installation leaves gaps. You also need the right tools to remove the door safely from its tracks if you're replacing the bottom seal.
Professional installation ensures a perfect fit and proper alignment. We handle the heavy lifting and get it right the first time. If you've already had repairs that didn't stick, give us a call to schedule a free quote and let us do it properly.
Spring and fall are ideal times to address seal problems. Winter drafts are painful to live with, but rushing a repair in cold weather isn't smart. Late summer is smart planning before autumn cooling costs spike.

How long do garage door seals last? Most seals last 5 to 7 years depending on climate and use. North Carolina's sun exposure and temperature changes accelerate wear. Inspect them annually and replace when you see cracks or gaps.
Can I replace just the bottom seal, or do I need to replace all three? You can replace seals individually. However, if the others are also worn, replacing all three at once ensures consistent draft protection and prevents repeat trips.
What's the difference between a bottom seal and a threshold seal? The bottom seal attaches to the garage door and compresses against the concrete. The threshold is a permanent fixture on the ground. Both work together to block drafts at the bottom edge.
Will new seals reduce my energy bills? Yes. Proper sealing can reduce drafts by 80 to 90 percent, lowering heating and cooling costs by 10 to 15 percent during peak seasons. Savings vary based on your existing door condition.
