Housing in this area was largely built between 1938 and 2005, with the median landing around 1980 across the wider service territory - but Cherry Hills Village itself centers closer to 1979, and the lots here tend toward larger custom builds rather than production-era subdivisions. That combination - an older door mechanism paired with a heavier, wider, or custom panel - is the root of most calls we take in this specific area. Add Colorado's cold and severe winter swings, and steel torsion springs that have held up for four decades start losing tension unevenly, especially on doors carrying more weight than a standard model. It's a mechanical fatigue problem accelerated by both size and climate, not a design flaw.
