Across the wider service area we cover out of Wheaton, the housing stock runs 1938 to 2003, with the median sitting around 1976. Homer Glen skews newer than that - most of the homes here went up around 1988. That decade matters for off-track calls. Builders were shifting toward lighter steel track sections and plastic roller brackets around then, cheaper to install but more prone to flexing under an unbalanced door than the heavier gauge track used on older builds. When a spring goes weak or a cable frays on one of these doors, the door doesn't just bind - it tends to walk sideways off the track hangers faster than it would on older, stiffer hardware.
The climate here still falls in the cold-moderate band, same as the rest of the region we work in, so frost heave under a slab-mounted track bracket is still in play even on a house built in the late 80s. A bracket that's lifted a quarter inch over a hard winter is enough to throw a roller off its rail the next time the door cycles. It's a newer-house problem wearing an old-house cause.
