Most of the garages we open around here were built between 1938 and 2004, with the bulk of the stock dating to the 1960s and 70s and a median build year near 1970. A door and track installed in a Harrisburg rowhome in 1965 is a different animal from new construction today - different spring sizing, different headroom, sometimes hardware nobody makes anymore.
We cover 53 named communities in this region, from Uptown a mile out to Wormleysburg and Lemoyne across the river at 2 miles, Camp Hill and New Cumberland a few minutes south, and out through Colonial Park, Linglestown, and Hershey toward Monroe at 13 miles. A lot of them share the same bones: narrow lots, single-car bays, and doors painted over two or three times since the Johnson administration.
This region also sits in a cold, severe winter climate band, and that matters as much as the build year. Earlier-built homes tend to carry heavier steel sections and older torsion hardware, while later ones run lighter doors with more opener electronics to go wrong. Either way, the fix starts with knowing which era you are standing in rather than guessing from a chart.
