With 1,607 households in Peotone and a median income of $104,792, we see a pattern: owners here tend to replace rather than patch when a door is actually worn out, and the doors we're called to are usually original torsion-spring sectional units from that late-1970s build wave, now 45-plus years old. The springs on those are past their rated cycle count even if they look fine. We also run into standard track-and-roller wear that's specific to that era's hardware gauge - lighter steel than what's used in newer installs, which means rollers bind sooner and need more frequent attention. Add in our region's severe cold winters, and steel tracks that are already undersized flex more in January than they did when the house was built. That combination - older light-gauge hardware plus real cold - is why a door that was fine in October can bind or drop a cable in February. We bring parts sized for that specific hardware, not a generic kit.
