Parts We Carry
We carry both 7-ball nylon rollers and steel ball-bearing rollers on the truck
Plus the stems and bushings that go with each. Most doors built around 2002, which covers a good chunk of Davidson, shipped with plain nylon rollers that have no sealed bearing at all - just a stem riding in a plastic sleeve. That's fine for a few years. It's not fine twenty-plus years later, which is where a lot of these doors sit now.
We stock the common stem lengths and both 7-inch and 10-inch options
Because one size does not fit every bracket on a door from this era. If your track is the narrower builder-grade profile that was common in early-2000s construction here, we match roller diameter to that, not to whatever's cheapest. We don't carry every obscure OEM roller for every door brand - if your opener or track is a less common make, that part may need to be ordered, which adds a day or two.
Why This Fails Locally
The housing stock across the broader service area runs 1959 through 2005, with a lot of it clustered in the 1980s and 90s. Davidson sits at the newer end of that - the typical house here went up around 2002. That matters because it tells you what kind of roller is wearing out right now: not the older steel-wheel hardware from a 1970s build, but builder-grade nylon rollers from a door that's only now hitting the twenty-year mark where the plastic gets brittle and starts to shed chips at the stem.
The cold-moderate climate here doesn't help. Nylon stiffens in winter, and a roller that's already thinning from two decades of cycling will crack at the stem junction on a cold morning instead of just wearing smooth. That's the failure we get called out for most on doors from this build era - not a seized bearing, but a roller that's physically broken and dropping fragments into the track.
The Cost of This Job
We don't have a flat number to quote here without seeing the door, so we won't make one up. What drives the cost is how many rollers need replacing, whether you upgrade from nylon to sealed steel ball-bearing rollers, and whether the track itself has been scored by the broken roller you're calling about. A full set swap on a double door costs more than fixing one bad roller on a single, obviously.
One honest note: a higher household income in an area doesn't change what the builder put on the door in 2002. We see plenty of well-kept Davidson houses running the same plastic rollers as anywhere else built in that stretch, because the roller isn't something most owners think about until it cracks.
How We Fix It
We run the job from Mooresville
It's about seven miles to reach Davidson, so there's no separate branch or depot here, just the truck making the drive. On site, we pull the bottom bracket rollers first since those take the most load and wear fastest, then work up the track checking each roller for flat spots, cracking, or a bent stem.
If the track has scoring from a broken roller dragging through it
We check whether it's cosmetic or deep enough to catch the next roller and cause the same failure again. Swapping rollers without addressing a damaged track just buys you a repeat call. We set tension and alignment after the swap so the door isn't riding heavy on one side, which is often what finishes off a roller that's already going.
Doing It Yourself
The bottom two rollers on each side are usually manageable for an owner with the door disconnected from the opener and the track section loosened - no spring tension involved at that bracket. The rollers up near the top, close to where the torsion spring and cable drum sit, are a different story. That's high-cycle, high-tension hardware, and a mistake there can put a cable under load you don't expect.
We also don't stock every roller size at retail counters nearby, so if you go the DIY route and need an exact stem length for a specific track profile, be ready to order and wait rather than finish it same-day. If you're not sure which rollers are load-bearing versus the easy ones, that's a reasonable thing to ask us over the phone before you start pulling brackets.
