Hardware differs by era
That matters more than people think. A door installed in 1985 uses different spring sizing and a different track profile than one put in during a 2005 remodel, and the opener hardware from each era fails in its own predictable way. We work on both: torsion and extension springs, steel and wood panel doors, chain-drive and belt-drive openers, rollers, cables, and the tracks that warp when a door gets slammed off its rails.
