Highland Village's housing mostly went up around 1993, which puts a good share of doors here a decade or more ahead of the newer construction found elsewhere across this service area, where the median build year runs closer to 2001. A door and hardware set that's approaching or past thirty years old has had a long run of cable cycles, and galvanized cables from that era weren't built with the coated, corrosion-resistant wire that's standard on newer installs.
North Texas heat plays a role too. Sustained high temperatures dry out the light lubrication on cable strands faster than in milder climates, and that dryness is what turns normal wear into fraying. On a door that's cycled a few thousand times since the early 90s, that's exactly the failure point we expect to find.
With median household income here at $164,459 - well above the $121,724 median across the wider service area - we see more owners choose to replace both cables and the drum together rather than patch one side and wait for the other to go. It costs more up front and saves a second trip.
