What Can Go Wrong
Duncan is a small town, only around 1,676 households, so the call volume we get from here is lighter than from the bigger named areas we cover. That doesn't mean the doors are simpler. It means when something does fail, it's usually tied to the age of the house, not wear from heavy daily use across a dense grid of streets.
Most of the broader Greer service area has housing going back to 1938, with a median build year of 1983 across the 32 communities we handle. Duncan runs newer than that average, with a median build year closer to 2001. That matters for the door itself. A house built in that window usually came with a factory steel door on a standard extension or torsion spring setup, not the older one-piece or hand-built wood doors you still find in the pre-1980s pockets elsewhere in the territory. The common failures we see out this way are the parts that wear out on a 20-plus-year-old standard system: a worn torsion spring, a stretched cable, a cracked roller, or an opener board that's finally given up after two decades of duty cycles. Track misalignment shows up too, especially on homes where the slab settled a little over the years. Panel damage from a backed-into door is as common here as anywhere.
The DIY Question
A torsion spring under tension can put someone in the hospital
And that risk doesn't change because the house is newer. If your door won't open and you can see a gap in the spring coil above the door, or the door is noticeably crooked when it's partway up, that's not a project for a Saturday with a borrowed wrench set.
What you can check yourself
The sensor eyes at the bottom of the tracks are clean and aimed at each other, the track bolts haven't worked loose, and the opener's travel limit hasn't drifted. Those are five-minute checks that solve a surprising number of 'my door won't close' calls. Past that, cable replacement, spring adjustment, and anything involving the torsion bar need a tech who does it regularly. We'd rather talk you through what you're looking at over the phone than have you find out the hard way why this is a two-person job with the right tools.
The Cost of This Job
We don't have a Duncan-specific price list to quote here, and giving you a number without seeing the door would be a guess dressed up as a fact. What we can tell you is what drives the cost on jobs like the ones common in Duncan's newer housing stock: whether it's a spring job or a full opener swap, whether the track needs realignment along with the repair, and whether the door is a standard single or a double that needs two springs instead of one.
Duncan's median household income, around $51,596, runs a bit below the wider service area's $55,671, and we factor that into how we talk about repair versus replace. On a door from the early 2000s, a repair is usually the right call before replacement even enters the conversation, since the hardware from that era isn't hard to source.
Booking a Visit
We run out of Greer, about 5 miles from Duncan, so a visit here means a short trip for the truck, not a cross-county haul. That's close enough that scheduling isn't the bottleneck it can be for some of the farther towns on our list, like Inman or Landrum.
When you call, tell us the age of the house if you know it and what the door is doing, or not doing. A door that won't budge, one that opens a few inches and stops, or one that's visibly off its track all point to different fixes, and knowing which one it is before the truck rolls saves time on-site.
What the Fix Involves
On a standard torsion spring replacement
A tech unwinds the old spring safely, measures the new one to match the door's weight and track length, winds it to the correct turns, and checks balance by hand before touching the opener. On an opener swap, it's disconnecting the old unit, mounting the new rail and motor, setting the travel limits, and re-pairing the safety sensors so the door stops and reverses correctly.
Most Duncan jobs we'd expect to be straightforward given the housing age here, standard hardware, no exotic parts
The exception is a house that's had a non-standard door installed at some point, custom width or an odd spring configuration, where parts might need to be ordered rather than pulled off the truck. That's the one honest limitation worth naming: if your door isn't a standard size or setup, the first visit might be diagnosis and the second is the fix.
