The median house in Elmhurst went up in 1964, which puts a good share of the neighborhood ahead of the 1976 median we see across the rest of the territory we cover out of Naperville. That gap matters for springs. A door built in the mid-1960s was almost certainly hung with a torsion spring on a raw steel shaft, no galvanizing, no oil-tempered coating standard on what ships today. If nobody's touched that spring since the house was built, it's been flexing under the same 5,000-plus cycles a year for six decades, and it's well past the point where fatigue failure is a matter of when, not if.
We run this call from Naperville, about 15 miles out. We don't keep a branch or a stocked van sitting in Elmhurst, so we're honest about it: we're driving in for the job, not around the corner from it. That doesn't change the work once we're on site, but it's worth knowing before you call expecting a same-hour drop-in.
