Across the wider service area the median house was built in 1978, with a lot of stock from the 1960s and 70s still standing. Troutdale runs later than that. The homes in this pocket, about 9 miles from our shop in Happy Valley, cluster closer to 1991, and that 13-year gap matters more than it sounds. A house framed in 1991 was built to a different set of door openings, different header heights, and different garage door hardware defaults than one framed in 1965. With 5,688 households in this specific area, you're not looking at a uniform tract either - some streets are infill from the 80s boom, others came in closer to the early 90s as the area filled out. The point is simple: the doors going bad here skew newer than the ones we're replacing on the older side of the service area, and the fix is different as a result.
