East Port Orchard's housing stock clusters tightly around a median build year of 1978, which means a large share of garage doors in the neighborhood are hitting the same wear point at close to the same time - not one house here and there, but blocks of them. A door built to 1978 standards was never insulated to modern R-values, and the region sits in a mild climate band with occasional freeze, so thermal performance matters less here than in colder markets, but the cumulative flexing from decades of temperature swings still fatigues steel panels and loosens track alignment.
With roughly 2,058 households in this pocket of the service area, the volume of doors built in that same narrow window is real, not incidental. When one homeowner on a street replaces a door from that era, it's rarely a one-off - it's usually the first of several on the same block dealing with the identical age and the identical hardware.
