Plano's service area runs from doors built as early as 1973 up through 2015, with the median landing around 2001. Corinth sits a few years ahead of that midpoint - most houses here went up closer to 1997. That's not a big gap on paper, but it's enough to matter on a garage door, because cable drum styles and track spacing changed more than once in the run-up to 2000.
A door installed in 1997 is old enough that its cable drums are usually the earlier stamped-steel style, not the grooved aluminum drums that came standard a few years later. When the cable finally frays or jumps the drum, replacing just the cable without checking the drum groove wear is how you end up back at the same door in eight months.
We drive out from Plano to reach Corinth, about 20 miles each way, so we're not doing walk-up diagnostics - every call gets a full look at the drum and track before we quote the fix. That's less about convenience and more about not making two trips for one door.
Corinth's roughly 8,143 households mean a fair number of these late-1990s builds are still on original hardware, which is the piece that actually breaks first.
