The wider service area runs from 1938 to 1993 with a median build year of 1970, but Oakfield doesn't sit on that median - most of the houses here went up around 1960, a full decade earlier than the area norm. With 516 households, it's one of the smaller pockets in the coverage area, and a good share of those garages are original to houses built in that same narrow window. That decade matters more than it sounds like it should. A door and track installed in 1960 was built to a different set of assumptions about spring tension, panel weight, and bracket spacing than one installed in the 1970s stock that makes up more of the area overall. The median household income here, a bit over $100,000, runs meaningfully above the wider area's figure, which shows up less in the doors themselves and more in what people choose to do with an aging one - replace it outright rather than nurse it along.
