Plano's housing stock was built mostly between 1973 and 2015, with the median home going up around 2001. That's not a small detail - it means a huge share of the doors, springs, and openers in this service area are now somewhere between 10 and 25 years past their install date, which is right where torsion springs fatigue, nylon rollers crack, and the first-generation openers from that construction boom start dropping signals or grinding gears. A door installed in 2001 wasn't built to last forever; it was built to the standard of the year it went in, and that standard has moved.
The moderate heat band this area sits in adds a second layer. It's not brutal like a desert climate, but summer heat cycles still dry out lubricant on tracks and cables faster than owners expect, and steel doors expand and contract enough over a season to loosen hardware that was torqued down 20 years ago. Combine a two-decade-old spring with a track that's never been re-lubed and you get the two most common calls in this area: a door that won't lift and a door that slams down. Neither is really about age alone - it's age plus heat cycling plus original-builder-grade hardware that was never meant to be maintenance-free.
