Factory-spec springs and rollers
That matters more than people think. If your house in Summerset still has its original door and opener, you're not dealing with the worn-out 1980s hardware we see elsewhere in the area. You're dealing with factory-spec torsion springs and rollers that are now pushing fifteen-plus years of cycles, which is right around when springs start to fatigue and nylon rollers start to crack or flat-spot.
