With 15,184 households in Newark, the housing stock here is smaller than the roughly 148,749 households across the full coverage area, but it's concentrated enough that the mid-1970s build era shows up consistently on our calls. Newark's median household income sits at $164,909, close to the area-wide figure of $168,292, and that tracks with what we see on site: owners maintaining original doors rather than replacing them outright, because the hardware still works even if it's aged. The area sits in a mild temperate climate band, without the freeze-thaw cycles or extreme heat swings that shorten spring and cable life elsewhere in the country. That's part of why 1970s-era hardware in Newark often still runs, just tired rather than failed outright. It also means panel warping from heat is less of a driver here than it is in hotter parts of the region. What ages a door here is mostly cycles and time, not weather.
