Kennewick's housing stock and its climate band work against original garage door hardware in a specific combination. Most of the houses in this service area, across the roughly 19,085 owner-occupied homes on this side of town, went up during the 1981-2000 stretch, which means a lot of torsion springs, cables, and chain-drive openers are now thirty to forty years into a service life that was never meant to run that long. Add a cold-moderate climate, and steel contracts and expands every winter-to-summer cycle enough to work bolts loose and stress metal that's already fatigued. It's not one dramatic failure - it's the slow accumulation of thousands of open-close cycles on hardware that was installed once and never touched again. We see the same calls repeat across the service area: West Pasco four miles out, Pasco at five, Riverview just north, Finley and Burbank further on, but it concentrates hardest right here in Kennewick's older blocks, where that original-era hardware is still doing the daily work it was never upgraded to handle.
