San Diego Country Estates sits apart from most of the neighborhoods we cover. Across the wider service area, the typical house went up between 1967 and 1992, with the median landing around 1978. Here, the median build year runs later - 1987. That decade gap matters more than it sounds like it should. A house built in 1987 came with a different garage door opener standard, different track spacing, and in most cases a steel sectional door instead of the older one-piece swing-up slab you still find on the 1960s and 70s stock elsewhere. With roughly 3,408 households in this pocket, we're not talking about a handful of outliers - this is the dominant build era for the whole area, not an exception to it. The mild temperate climate band covering this part of the county means the doors here haven't taken the kind of heat-cycle or freeze damage you'd see further inland or at altitude, so when something fails at this age, it's almost always wear and hardware fatigue, not weather damage.
