Most houses in Vail were built right around 2007, which means a lot of garage doors out here are still running the exact spring, cable, and opener that came with the house from the builder. Nobody's swapped them yet because nothing's obviously wrong - until a spring lets go or the opener starts grinding instead of lifting. A torsion spring is rated for a set number of open-close cycles, usually somewhere in the 10,000 range, and a door installed in 2007 that gets used twice a day has already burned through most of that. Rollers wear the same way - quietly, then all at once, usually as a loud bang or a door that jumps in the track. On a newer build like most of Vail's stock, the failure is rarely the door panel itself. It's the moving parts underneath it that have been working since the house was framed, and those don't last as long as the door they're attached to.
