Mount Prospect has roughly 22,003 households, and the median household income runs about $103,911 - higher than the roughly $96,794 median across our wider service area of 325,582 households. That income gap shows up in the calls we get: more requests for insulated steel doors and quieter belt-drive openers, fewer calls asking us to stretch the life of a door past what's reasonable. None of that changes the physics of a 1969-built garage, though. The hardware still ages the same way, springs still fatigue on the same cycle count, and the cold still stiffens metal parts every winter regardless of what the house is worth. What it does mean is that when we're out this way, we're usually replacing rather than nursing along, and homeowners tend to want the job done once rather than patched twice.
