A door installed around 1993 has had three decades of cycles on the same torsion spring, and torsion springs are rated in cycles, not years. At two to four openings a day, that spring is well past its expected working life in most Highland Village homes, even ones that look fine from the driveway. The failure mode is usually sudden: the spring snaps, the door won't lift, or it slams down because the spring that was supposed to carry the weight isn't carrying it anymore.
The other common issue is the opener itself. A unit from the 90s or early 2000s is on borrowed time electrically, even if the motor still turns. Capacitors dry out, logic boards fail, and replacement boards for units that old are getting hard to source. At that point we're usually talking opener replacement rather than repair, which is a different conversation and a different price than swapping a spring.
Highland Village's higher household income compared to the wider service area means we also see more owners who've already upgraded to a newer belt-drive opener on an otherwise original door. That mismatch - new opener, old hardware underneath - creates its own failure pattern when the old track or rollers can't keep up with the newer opener's pull.
