Prairie Village's housing stock centers on 1959, a good two decades ahead of the median build year across the rest of the service area. That matters more than most homeowners realize. A door hung in 1959 has had three owners, two openers bolted onto it at different points, and in a lot of cases the original torsion spring and drums are still doing the job they were sized for in the Eisenhower administration. Steel fatigues. Springs rated for a certain cycle count don't send a warning before they let go - they just snap, usually on a cold morning when the metal has already contracted and lost some give. We're coming from Shawnee, about 9 miles east, so when a spring breaks here it's rarely a brand-new part failing. It's hardware that's been quietly wearing out since before most of the current owners bought the house. Add in a winter cold snap - this area sits in a moderate-cold climate band - and the stress on old torsion springs and brittle rollers goes up fast. The fault pattern we see leans toward snapped springs, frozen or seized rollers, and cables that have been fraying for years without anyone noticing until the door won't lift.
