Atlanta's service area runs through 36 named areas, and the housing underneath nearly all of them dates to the same stretch - median build year 1978, most of it going up in the 1960s and '70s. That means a huge share of the doors we're called to are original torsion or extension setups on hardware that's now decades past its spring-cycle life, or replacement doors installed on brackets that were never upgraded when the door itself changed. Add the region's cold-moderate climate band, where temperatures swing enough over a winter to stiffen grease, shrink steel cables just slightly, and make a spring that's already fatigued finally snap on a cold morning instead of a mild one. That's the pattern across the metro's 232,839 households and 80,135 owner-occupied houses we serve: it's not that Atlanta doors are unusual, it's that so many of them are the same age, carrying the same worn springs, in a climate that stresses the metal in the same direction every winter.
