Sycamore's median household income sits at $80,837, a bit below the $89,488 median across the full service area, and that gap shows up in how long people wait before calling - more households here run hardware to failure instead of replacing it on schedule. A torsion spring rated for 10,000 cycles doesn't care about income; it breaks on the same curve whether the house is in Sycamore or anywhere else, but a thirty-year-old spring in a 1992 house is now well past that curve regardless of budget.
With roughly 7,499 households in Sycamore, a meaningful share of these doors are hitting that same age wall at close to the same time, which is why we're seeing more spring calls here now than we did five years back.
