Most of the housing in this service area went up between 1950 and 2004, with the bulk of it clustered in the 1980s and 90s across the eighteen named communities we cover. That means a lot of torsion springs and steel tracks installed during the same stretch of years are all hitting end-of-life at roughly the same time - springs are rated for a set number of open-close cycles, and a 40-year-old spring doesn't care that it still looks fine on the outside. Add in a cold-moderate climate band: steel contracts and stiffens when temperatures drop hard overnight, grease in the rollers and hinges thickens, and a door that worked fine at 5pm can bind or snap a cable by morning. Homes near Lake Quivira, about 2 miles out, deal with extra overnight condensation off the water, which speeds up rust on cables and hinge pins faster than it would in a drier garage. None of this is damage from one bad day - it's cumulative, and it shows up as a sudden failure because that's how fatigued steel and dried-out lubricant finally give..
