We don't publish a flat number for spring repair because the cost depends on what's actually on the door, and in Elmhurst that's less predictable than in a newer subdivision. A straightforward pair of torsion springs on hardware in decent shape is one job. A door where the drum's worn, the bearing plate is rusted through, or the shaft needs replacing along with the spring is a different job with different parts. Elmhurst's median household income runs well above the wider service area's overall figure - $145,374 against roughly $96,794 - and we mention that only because it doesn't change what parts cost. Age of the hardware, not the neighborhood's income, drives the price. We'll give you a number after we've looked at the actual springs, drums, and shaft, not before.
