Dacula sits about 10 miles from our shop in Winder, and the houses out here skew newer than a lot of what we see across the rest of the service area. The median build year here is 2001, which puts most garages into the era of pre-hung steel sectional doors on standard torsion springs mounted on a single center shaft over the opening. That's a different animal from the older one-piece and side-mount setups you find in some of the older pockets we cover. Across the wider territory, the housing stretches from 1976 up through 2012 with a median around 1995, so Dacula sits a few years newer than the area as a whole. That matters because the hardware changed over that window - torsion spring sizing, drum style, even the gauge of track - and a repair that's routine on one house can be the wrong part entirely on another built even five years apart.
