A door that went up around 1993 was almost certainly built with an extension-spring system running along the horizontal track and a single non-insulated steel panel - that was the standard setup for that build year, not a sign of a cheap original installer. Extension springs have a shorter working life than the torsion springs used on most doors built since, and after three decades of cycles, the hardware is past due whether or not it's actually failed yet. With roughly 5,380 households in Highland Village, that's a fairly contained, known pattern across the area rather than a scattered guess - a lot of doors up here are hitting that same age wall around the same time. The moderate heat band this area sits in doesn't push insulation the way a harsher climate would, so the failure driver out here is mechanical age and spring fatigue more than weather stress on the panel itself. That's also why a repair quote and a replacement quote can land close together on these older doors - once the spring system and the track are both worn, patching one piece often just delays the next failure by a season.
