The pattern we see across this stretch of Clackamas County - Happy Valley, Damascus three miles off, Oatfield at four, Gladstone at five - comes straight from when these neighborhoods were built. A house framed in 1978, the median year for this area, got a door sized and hung to the standards of that decade: lighter gauge steel, simpler spring systems, openings cut to the rough dimensions builders used then. That hardware was never built to run forty-plus years, and the climate here doesn't help it along - mild most of the year, but with enough freeze nights to make old steel brittle and crack at the bottom panel seam where moisture sits. With 44,493 owner-occupied houses out of 87,301 households across the service area, a lot of these doors are still the first one the house ever had. The failure mode is almost always the same: the opening hasn't moved, the house hasn't changed, but the door and hardware simply aged out of a job they were only ever built to do for twenty or thirty years.
