Burlington is a smaller piece of the service area we run from Florence, about 6,691 households compared to the roughly 97,578 across the whole territory. A smaller town doesn't mean fewer calls, but it does mean the calls cluster around the same kind of house. Most of Burlington went up around 1999, which is a full fifteen years newer than the 1984 median we see across the broader area. That gap matters more than it sounds. A door built in the late 90s or 2000s is almost always a steel sectional on torsion springs, not the older one-piece slab doors or light-duty extension-spring setups you still find on houses from the 1938-2005 spread elsewhere in the territory. The failure points follow the hardware. In a torsion system, it's the spring cycling out, the center bearing wearing, or the cable fraying at the drum. You don't see the same rate of flat-spring snaps here that you do in the older pockets of the area, because there just aren't as many of those doors left standing in Burlington to begin with. The climate band is the same severe-cold zone as the rest of the area, so winter still shortens spring life no matter how new the door is - cold steel flexes less and cycles harder on the coil.
