1969 later than comparison
Homes in Mount Prospect went up mostly around 1969, later than a lot of the older 1960s stock we see elsewhere in the service area, so the springs, drums, and openers we're pulling out tend to be a second or third generation replacement, not original 1960s hardware. That usually means standard modern parts are already on the door, which keeps a repair simpler and the bill lower than a house still running gear from its first build.
