The call we get most from Durand is a door that won't move at all, and nine times out of ten it's a torsion spring that let go overnight. That's not random. Durand's housing sits around a median build year of 1950, which is noticeably older than the 1976 median across the rest of the service area we cover from Fenton. Doors and openers installed on homes from that era have usually been replaced once already, sometimes twice, and the hardware underneath - the track brackets, the end bearings - is often a mismatched patchwork from whichever repair happened last.
Older torsion setups in this town tend to run heavier gauge springs than what you'd find on a house built in the 1970s, because the doors themselves were often heavier wood-composite panels before steel took over. When a spring on one of these snaps, it snaps loud and it takes the cable with it more often than on newer doors. We also see more cases here where the opener is a later add-on bolted to original track that was never sized for motorized pull, which stresses the rollers over time and shows up as a door that reverses itself or won't seal at the bottom.
