Chino Hills is a different build era than most of the towns we cover from Yorba Linda. The median home here went up around 1990, call it twenty years newer than the median across the rest of the service area, where the typical house dates to 1968 and the bulk of the stock is 1960s-70s construction. That gap matters more than it sounds like it should. A door and opener installed in a 1990 tract house is a different animal from one installed in a 1965 ranch - different track width, different spring mounting, often a different opener drive entirely. When we get a call from Chino Hills, we're not walking into the same hardware we see in the older pockets of the territory. We're working on doors that are, on average, two decades younger, which changes what tends to break and when. Roughly 25,485 households sit in this part of the service area, most of them in homes built well after the region's older neighborhoods were already established. That's the starting point for everything else on this page.
