Palmer has around 745 households, which is small enough that most of the town's garage doors were put up within a narrow window rather than spread across decades. The median home here dates to 1988, which puts a lot of doors and openers right in that late-80s stretch - steel panel doors on torsion or extension springs that are now well past the age where lubrication and adjustment stop being optional.
Compare that to the wider service area, where houses run from 1976 through 2014 with a median around 1996 across thirteen named communities. Palmer sits on the older side of that range, which means the springs, rollers, and cable drums we see on a Palmer call are more likely to be original or first-generation replacements than the newer torsion setups common in houses built after 2000.
A small town like this also means fewer doors getting attention on any kind of schedule. In a bigger suburb, someone eventually calls because a neighbor did. In a town of 745 households, a door can run rough for years before anyone decides it's worth a truck coming out ten miles from Waxahachie.
