For a straightforward spring or roller swap on original hardware, the door goes back into service the same visit - that part isn't in question. Where it slows down is parts that aren't common stock: an odd-width original track bracket or a drum sized for a door style nobody's made in decades. Median household income in Niles runs around $49,987, noticeably below the $62,149 median across the wider service area, and that's part of why we lean toward repairing original hardware where it's sound rather than defaulting to full replacement - it's usually the cheaper path for a household budget in this range, and it keeps the door out of the landfill a while longer. With 8,506 households in Niles against roughly 62,317 across the whole service area, this is a smaller pocket of older housing, and we plan the truck's parts around that pattern rather than around what a newer subdivision would need.
