Cedar Mill sits apart from a lot of the territory we cover. Across the wider service area the typical house went up back in 1978, but Cedar Mill's median build year lands around 1992 - a solid decade and a half newer. That gap matters more than it sounds like it should. A house framed in 1992 came with a different garage door section profile, different track spacing, and almost always a chain or belt-drive opener instead of the older screw-drive or early chain units builders were still putting in through the 1970s. The 6,578 households here are mostly living with hardware from a narrower, later window than you'd find a few miles south or west, where 1960s and '70s construction still dominates.
That later build date also tracks with household income in this area, which runs well above the service-area median - a number that often correlates with earlier adoption of insulated steel doors and keypad entry rather than the bare single-layer panel doors common on older stock. None of that means Cedar Mill doors don't fail. It means they fail in a different order than older houses do, and a tech who assumes 1970s hardware here will bring the wrong parts.
