Mount Pleasant's median home here was built around 1981, which puts most of the housing stock a few years ahead of the older 1938-built homes you still find scattered through the wider Columbia service area. That matters because a house built in 1981 almost never has the original one-piece door anymore, but it very often still has the original torsion spring setup or a first-generation chain-drive opener bolted onto it decades later. Across the broader area we cover, the housing runs from 1938 up through 2013 with a median around 1986, so Mount Pleasant sits close to that overall average but leans slightly older. With roughly 2,055 households in this area and a median income near $49,897, we see a lot of owners doing careful repair-over-replace math rather than swapping a door out just because it's aging. That's a reasonable call in plenty of cases - a worn 1980s door with solid panels and a bad spring is usually a repair, not a replacement. Where it stops being reasonable is when the track is bent, the panels are rusted through, or the opener is an older unit with no safety reversal sensors. We'll tell you straight which category your door falls into instead of defaulting to a sales pitch.
