We run out of McDonough to work on doors across 17 named areas, and the houses we find when we get there span a wide range. Across the service area, homes were built anywhere from 1938 to 2007, with the median landing around 1976 - which tells you most of what you need to know before you even open the garage. The bulk of the stock in these towns went up in the 1960s and 70s, the era of plain steel sectional doors, chain-drive openers bolted to joists that have since settled, and torsion springs sized for lighter insulated panels that didn't exist yet. Closer in, towns like Locust Grove (7 mi) and Hampton (10 mi) sit inside that same build window. Farther out - Lithonia (19 mi) and Panthersville (20 mi) are the longest hauls we make - you still land mostly in that 60s-70s band, though pockets run newer where subdivisions filled in later. We don't have a lot-by-lot breakdown of when each town was built, so we won't pretend to tell you your house's exact year from this page. What we can tell you: if your door or opener looks original and your neighborhood dates to that mid-century wave, the failure points are predictable, and we've seen them on plenty of jobs out that way.
