The service area sits in a cold-moderate climate band, and that swing between summer heat and winter cold is hard on steel hardware over a long season. Tracks expand and contract slightly with temperature, and over enough cycles that movement loosens the bolts holding the track to the jamb - a slow problem that shows up as a door that rattles more than it used to.
Because Triana's housing stock is newer, built around a 2012 median rather than the 1989 median seen across the wider area, we see less rust-through on tracks and springs here than in older sections of the service area. What we see instead is wear tied to use rather than age - openers and springs rated for a set number of cycles, used daily for over a decade, simply reaching the end of that count.
