In our years serving Whitsett, we've seen this problem again and again: homeowners ignore a worn bottom seal or cracked threshold, then wonder why their heating bill climbs or bugs find their way inside. Weather stripping and seals are not glamorous, but they're the difference between an efficient garage and an energy sieve. Here's what you need to know to keep your door tight and your wallet fuller.
Garage door seals take a beating. The bottom seal slides across concrete dozens of times a day, absorbing UV rays, temperature swings, and moisture. In North Carolina's humid climate, rubber degrades faster than most homeowners expect.
Most bottom seals last 5 to 7 years before they crack, harden, or lose compression. The threshold (that rubber or vinyl strip at the base) can fail even sooner if your driveway settles unevenly. Once gaps appear, warm air escapes in winter, cool air leaks out in summer, and pests find entry points.
Whitsett sits in Randolph County where we see real seasonal shifts. Summer heat and winter cold put constant stress on seals. If you haven't replaced yours in five years or more, it's worth a quick inspection.
A small draft might seem harmless. It isn't. A quarter-inch gap around your door can waste the equivalent energy of leaving a window cracked open all day. Over a heating or cooling season, that adds up to real money on your utility bill.
Beyond energy loss, drafts invite: - Moisture that promotes mold and rust, Insects and rodents seeking shelter, Dust and pollen into your garage, Moisture damage to stored items
We've had customers in nearby Asheboro report $30 to $50 monthly increases during winter because their seals had failed. Once they replaced the bottom seal and threshold, that cost vanished.

Not all seals are created equal. The bottom seal is the most critical. It compresses against the concrete as the door closes, forming a tight barrier. If it's cracked, hardened, or no longer sits flush, replacement is overdue.
Side seals and top seals prevent drafts along the edges. These tend to last longer but still need inspection annually. The threshold is the horizontal strip at ground level. Unlike the bottom seal (which hangs from the door), the threshold is mounted to the concrete itself. If your driveway has settled or shifted, the threshold may no longer align properly with the door.
Replacing these is straightforward work, but it requires the right parts and technique. Using the wrong seal material or improper installation means the job fails in months instead of years. That's why getting an accurate estimate from a local pro matters more than you'd think.
You can buy replacement seals at hardware stores for $20 to $60. Installation looks simple: remove old seal, slide in new one, done. Reality is messier.
If the track is bent, the seal won't compress evenly. If the door isn't level, gaps remain. If you use the wrong gauge or material, it'll fail early. Most homeowners who try this find themselves frustrated and calling us within a month.
Our team handles it right the first time. We inspect the entire assembly, level the door if needed, and install seals that last. The cost is reasonable, and you avoid two trips to the hardware store plus a redo.

The best time to replace seals is late summer or early fall, before cold weather arrives and heating demands peak. Spring is the second-best window. Winter and mid-summer are tougher because temperature swings can stress new seals before they've settled.
That said, if you're losing energy now, waiting six months costs money every single day. Don't let a small seal problem balloon into a big bill.
Seal replacement shouldn't be expensive. If a company quotes over $300 for a bottom seal and threshold, ask why. Honest pricing means you pay for the parts, labor, and a brief inspection. Nothing more.

How do I know if my bottom seal needs replacement? Look for cracks, hardening, or gaps between the seal and concrete when the door closes. If you see visible light under the door or feel a draft, replacement is due. Most seals last 5 to 7 years in North Carolina's climate.
Can I replace seals myself? Yes, if your track is straight and the door is level. Many homeowners succeed. If the door isn't perfectly aligned, DIY seals fail quickly. A professional inspection costs little and saves frustration later.
What's the difference between a bottom seal and a threshold? The bottom seal hangs from the door and compresses against the ground. The threshold is a fixed strip on the concrete. Both prevent drafts, but they wear differently and may need replacement at different times.
How much does weather stripping replacement cost? Expect $150 to $300 for bottom seal and threshold replacement, depending on your door size and condition. Get a free estimate to know the exact cost for your garage in Whitsett.
When should I replace seals? Late summer or early fall is ideal, before heating season. If you notice drafts or energy loss now, don't wait. Call us for same-day service and stop wasting money today.
