James Island's median house went up around 1971, which puts a big share of the island's garages a full generation ahead of the newer subdivisions you see elsewhere in the Charleston service area, where the broader median lands closer to 1989. That gap matters more than it sounds like it should. A door and opener installed in the early-to-mid 1970s has usually been replaced at least once by now, but the track brackets, the header clearance, and sometimes the framing around the opening are still original to the house. We see a lot of garages here where someone swapped in a newer door or a newer opener over the decades but left the old jamb hardware in place because it still technically worked. That mismatch is where most of our island calls start - not a dead opener, but an opener fighting hardware that was never sized for it. With roughly 4,398 households on the island, that older build pattern isn't a handful of outlier homes, it's the baseline we plan a job around before we even load the truck.
