Mount Prospect's median household income sits at $103,911, a notch below the $112,168 median across the wider service area. That gap matters when a spring breaks or a panel caves in, because it changes where the repair-or-replace line falls. On a house at this income level, a $250-$450 spring or roller repair makes sense almost every time. A full door and opener swap is a bigger call, and it's one we walk through with you rather than push.
The other number that matters more here is the house itself. Mount Prospect's housing stock centers on 1969, older than the 1977 median across the broader area we cover. A door built or replaced in that era usually means a single steel torsion spring, an older extension-spring setup in the garage ceiling, or a door skin thin enough that a bent panel is a wall-thickness problem, not a hardware problem. None of that shows up on a newer build a few miles out. It's the reason the same symptom on two different streets can call for two different fixes.
