Coto de Caza's housing stock centers on 1995, noticeably newer than the broader service area's 1983 median. That gap matters more than it sounds like it should. A door installed in the mid-1990s is a different animal from one installed in the early 1980s - heavier insulated panel construction became standard by then, and most garages were built with wider openings to match. With roughly 5,010 households in the area and a median income well above the regional figure of $136,352, a lot of these doors were higher-spec to begin with: thicker steel, factory insulation, sometimes custom wood-look overlays. That changes the failure pattern. The springs sized for a lighter 1970s door are undersized for a 1995 insulated one, so when a homeowner here swaps a spring without checking the door weight, it fails again within a year or two. We see that mismatch often enough that it's one of the first things we check before touching anything else.
