Cherry Hills Village's housing stock centers on 1979, putting it right at the front edge of the service area's broader 1980s-90s wave. That generation of door hardware was built for a different set of expectations - lighter openers, simpler torsion setups, steel that wasn't engineered for the freeze-thaw cycling a severe cold climate puts it through year after year. Steel contracts in deep cold and expands again in a January thaw, and that repeated flex is what loosens hinge screws, stiffens spring steel, and eventually throws a track out of alignment by a few millimeters - enough to make a door bind or reverse on its own. With 2,227 households in Cherry Hills Village, this is a smaller, higher-value pocket than the roughly 60,666 households and 33,238 owner-occupied homes across the wider area we cover, but the doors themselves age on the same clock as everyone else's. The metal doesn't know what the house is worth.
