Your garage door leaks cold air. Energy bills spike. You feel the draft every time you walk past the threshold. In our years serving Seaboard, we've seen this problem again and again, and the fix is simpler than most homeowners think: worn weather stripping and seals. A $200 replacement today beats a $1,500 heating bill this winter.
Garage doors aren't sealed boxes. The moving panel creates gaps at the top, sides, and bottom. Weather stripping and seals bridge those gaps. Over time, rubber hardens, cracks, and pulls away from the frame. Temperature swings, humidity, and UV exposure in North Carolina speed up this deterioration. Most seals last 3 to 5 years before they stop doing their job.
The bottom seal takes the worst beating. It sits on concrete, absorbs moisture, and flexes every single time the door opens and closes. Ice, debris, and salt from winter roads accelerate breakdown. When the bottom seal fails, drafts rush in. So does cold air, insects, and rain spray.
Not all air leaks are obvious. Check four zones: the side tracks, the top of the door frame, the garage-door panel edges, and the threshold at the base. Run your hand along these areas on a cold day. Feel a breeze? That's money flowing out of your home.
The threshold is the most common culprit. It's a rubber or vinyl strip that sits between the garage floor and the bottom of the door. When it compresses or splits, it can't seal anymore. A faulty threshold alone can account for 10 to 15 percent of your heating loss.
Seaboard homeowners in older homes often have original seals that are decades old. If your garage door was installed before 2015, replacement seals will almost certainly improve comfort and lower your utility cost.

Weather stripping and seal replacement is one of the most affordable garage door fixes available. A complete bottom seal replacement typically runs $150 to $300. Side seals and top weatherstripping add another $100 to $200. Installation takes 1 to 2 hours.
When you get an estimate, ask whether the price includes removal of old, hardened sealant. Some companies charge extra for cleanup. We don't. Our estimate covers labor, materials, disposal, and testing. We'll show you the worn seals so you understand exactly what we're replacing.
Compare this to the cost of heating an uninsulated garage all winter. If your garage is attached to your home, cold air migrates inside through walls and doors. You end up running your furnace harder to compensate. Over a season, that can easily exceed the cost of new seals.

Some seals are easier to replace than others. Side tracks and top seals can be a straightforward swap if you're handy. The bottom seal is trickier. It requires precise measurement, alignment, and securing. A misaligned bottom seal will wear unevenly and fail faster.
If the threshold itself is cracked or the garage-door frame is bent, DIY becomes risky. Professional installation ensures the seal sits flush against the surface, creating a true barrier. That's the difference between a fix that lasts 3 years and one that lasts 5 to 7 years.
Our team handles the hard part: we measure twice, cut once, and test the seal under the door's weight. You get the peace of mind that it was done right the first time.
Once you've replaced weather stripping and seals, simple care extends their life. Keep the bottom seal and threshold clean. Sweep debris weekly. In winter, check for ice buildup. In spring, rinse salt and dirt off the seals with a hose.
Inspect seals twice a year: spring and fall. Look for cracks, hardening, or separation from the frame. Catch problems early and you'll avoid emergency repairs during bad weather.

Your home's comfort is worth the call.
How do I know if my weather stripping needs replacement? Look for cracks, hardening, or gaps between the seal and frame. Feel for drafts on cold days. If your bottom seal is compressed or pulling away from the door, replacement is overdue.
Can I replace weather stripping myself? Simple side seals are DIY-friendly. Bottom seals require precise alignment and are best left to professionals. Improper installation reduces effectiveness and shortens seal life.
How often should weather stripping be replaced? Most seals last 3 to 5 years in North Carolina's climate. Inspect annually and replace when you notice wear, cracking, or loss of flexibility.
Will new seals lower my heating bill? Yes. Poor seals account for 10 to 15 percent of heating loss in attached garages. Replacement typically saves $20 to $50 monthly during winter months.
What's the difference between weather stripping and a bottom seal? Weather stripping is the rubber or vinyl trim on side and top tracks. The bottom seal is a heavier-duty threshold that runs along the garage floor. Both serve the same purpose: blocking drafts.
