The failure pattern in Western Springs tracks the housing stock, not bad luck. A door installed when the house was built around 1960 has had 60-plus years of cable cycles, and even a replaced cable on old, un-resurfaced drums wears unevenly because the drum grooves themselves have deformed over time. We're in a cold moderate climate band here, and cable strands that have any fraying tend to snap on the first hard cold snap of the season, when the steel contracts and the lift load spikes on a stiff door. Add in original torsion bars that were never rated for a heavier insulated door if one got swapped in later, and you get a cable doing more work than its gauge was built for. This isn't a Western Springs-specific defect - it's what happens anywhere a large share of the housing predates modern door hardware standards, and Western Springs' 1960 median build year puts a lot of doors in that window. The honest limit here: if the drums are also worn or pitted, we're not just replacing a cable - that's a drum-and-cable job, and we'll tell you that on-site rather than sell a patch that fails again in a year.
