With 1,002 households in Shady Shores and a median income north of $158,000, this is a town of owners who bought once and haven't had reason to touch the garage door since move-in - which means a lot of original springs are still in service well past the point where they'd normally have been swapped. The heat here runs moderate rather than extreme, so you're not fighting the kind of cable-shrink and lubricant breakdown that shows up in harsher climates, but two decades of Texas summers still dries out factory grease and stiffens rollers that were never upgraded. Add in a housing stock that's almost entirely one era - 2000, give or take a couple years - and you get a very consistent failure pattern across the whole town: original torsion springs reaching the end of their cycle count around the same time, on doors that are otherwise in decent shape.
