With about 5,734 households in this pocket and a median income of $79,739, Glenn Heights is solidly a homeowner area rather than a rental-heavy one, and that shows in how doors get maintained - or don't. Owner-occupied houses tend to get a door replaced or a spring swapped reactively, right when it breaks, rather than on a maintenance schedule. Combined with the moderate heat load this part of Texas carries, the plastic and nylon rollers common in early-2000s builder-grade doors dry out and crack faster than the steel rollers on older stock. Openers from that era are also hitting the age where capacitors and circuit boards fail on their own timeline, independent of how well the door itself was cared for. So the common call here isn't a bent track from decades of use - it's a spring that was never rated quite heavy enough for the door, or an opener board that finally gave out after twenty-some years of Texas summers.
