The typical house in this part of the service area went up around 1973, right in the middle of the 1960s-to-1998 build window that defines most of the stock we work on. That era means torsion springs sized for doors heavier than today's insulated panels, extension springs on older single-car openings that were never updated, and openers from at least one generation before the current safety-sensor standard. None of that is unique to Nederland's exact address, but it is unique to a town built out in that window rather than one built in the 1990s or after 2000. The climate here is mild with occasional freeze risk, not the deep freeze-thaw cycle that cracks concrete aprons further north, so the failures we see are age and cycle-count failures - metal fatigue, dried-out lubricant, a cable that's frayed from ten thousand lifts - not weather damage. A door that's original to a 1973 build has had roughly fifty years of cycles on hardware that was never designed to last that long without a spring swap.
