Across the wider service area, most garage doors date to the 1960s and 70s, and Elmhurst fits that pattern closely - the town's own housing runs to a median build year of 1964. Most of the original doors here have already been through at least one roller replacement, sometimes with a mismatched set bought off a shelf without anyone checking the track gauge first.
This area also runs higher household income than the service area overall, where the median household income is $97,861. Elmhurst's own median sits well above that, and we mention it only because it changes what gets fixed versus patched: owners here are more likely to ask for the whole roller-and-track assembly redone properly rather than one bad roller swapped out while the rest limp along.
