Most people don't think about their garage door until something stops working. But long before a spring snaps or the opener fails, your weather stripping and seals are quietly leaking heat, cold, and your hard-earned money. A worn bottom seal or cracked threshold lets drafts pour in year-round, driving up energy bills faster than you'd expect. The good news: fixing this is straightforward, affordable, and something we handle all the time here in Bunn.
Your garage door's weather stripping and seals serve one critical job: creating an airtight barrier between your garage and the outside. The bottom seal is the workhorse. It's the rubber or vinyl strip that runs along the bottom edge of the door and compresses against the threshold when the door closes. The side seals do similar work along the left and right jambs.
When these components work properly, they keep out wind, rain, insects, and temperature swings. Your HVAC doesn't have to compensate for garage air leaks. Your heating and cooling stays where you want it. When seals fail, all that goes away.
Weather stripping and seals aren't meant to last forever. UV exposure, temperature cycling, and constant compression break down rubber and vinyl over time. In North Carolina's humid climate, moisture speeds up that decay. Most seals last 5 to 7 years before they crack, harden, or shrink.
The bottom seal takes the most punishment because it slides against the concrete threshold every single day. It collects dirt, grit, and moisture. Over time, it becomes brittle and loses its seal. Side seals often outlast bottom seals, but not by much.
If you notice daylight around the edges of your closed garage door, or you feel a draft even when everything looks shut tight, your seals have probably reached the end. That's the signal to call. We can schedule a free quote and check your door's condition same-day.

Here's the honest math. A worn threshold and bottom seal can add 5 to 10 dollars per month to your heating or cooling bill, depending on the season and your thermostat settings. Over a year, that's 60 to 120 dollars in wasted energy. Over five years, it's 300 to 600 dollars. And that's just the energy cost. You're also letting in moisture, which can damage stored items, encourage mold, and shorten the life of anything metal in your garage.
Replacing seals costs a fraction of that waste. It's one of the smartest maintenance moves you can make, especially if you also perform routine maintenance on your garage door.
Look for these signs:
1. Visible cracks, splits, or hardening in the rubber or vinyl. 2. Daylight visible around the bottom or sides when the door is closed. 3. Water pooling or staining on the garage floor near the door. 4. Cold air or drafts even when the door is sealed. 5. Debris or dirt caked on the seal that won't clean off.
If you see one or more of these, replacement is overdue. It's a simple, non-emergency fix that we can handle quickly.
Replacing weather stripping and seals is straightforward. We remove the old, degraded material, clean the frame, and install new seals that match your door's profile. Most bottom seal replacements take under an hour. Side seals may take a bit longer depending on how they're attached.
The key is using the right material for your door type and local climate. We stock seals suited to Bunn's weather and can match your door's specifications exactly. No guessing, no ordering the wrong size.
Replacing worn seals is part of keeping your garage door healthy overall. When seals work properly, they reduce strain on your opener and springs because the door doesn't have to fight wind or pressure imbalances. They also protect your door from water intrusion, which can rust springs and corrode hardware.
If you haven't had your seals checked in a few years, or if your energy bills have been climbing, reach out. We'll inspect your door and give you honest pricing with no surprise charges. Contact us to get a same-day estimate or call (252) 557-8293.
Q: Can I replace weather stripping myself? A: You can if you're handy and have the right tools, but precision matters. Seals must fit snugly or they won't work. Professional installation ensures no gaps and proper compression.
Q: How long do new seals last? A: Quality seals typically last 5 to 7 years in North Carolina's climate. Harsh weather and frequent door cycles may shorten that window.
Q: Will new seals stop all drafts? A: New seals stop drafts from the door itself. If your garage has other air leaks (gaps around the frame, poor insulation), those need separate fixes.
Q: Is this an emergency repair? A: No. Worn seals are a maintenance issue, not an emergency. Plan ahead, but don't delay too long or you'll keep wasting money on energy.
Q: What's the difference between rubber and vinyl seals? A: Rubber handles temperature swings better. Vinyl is often cheaper but hardens faster in cold. We recommend the best fit for your situation and budget.
