The median home in Highland Village was built around 1993, which puts a lot of original hardware at roughly thirty years of service - past the rated life of a torsion spring under normal cycling, and right in the window where nylon rollers start cracking from sun and heat rather than cold. This part of Texas sits in a moderate heat band, so the common failure here isn't a frozen track, it's UV-dried lubricant and brittle plastic idler bearings that finally give out on a July afternoon. With household income in this area running well above the regional median, a fair number of these doors also got a cosmetic upgrade at some point - insulated inserts or a new skin - without the torsion spring or opener ever being touched, so the spring underneath is still the original, now mismatched to a heavier door than it was sized for.
