Belvedere has about 2,314 households, smaller than the wider service area's roughly 20,921, and median household income here runs about $57,933 - noticeably above the $51,180 median across the full coverage area. That income gap shows up in the calls: more Belvedere homeowners ask about full door replacement with insulated panels rather than patching an old one, and more are willing to upgrade hardware rather than just keep a worn spring limping along.
The area sits within the broader stretch of homes built mostly in the 1960s and 70s across this part of the service territory, but Belvedere's own median year, 1967, runs a bit older than some of the newer pockets closer to Aiken. That means original steel is more common here, and original-spec springs and track are more likely to still be in place, unreplaced, on houses that haven't changed hands in a generation.
Climate here is mild with occasional freeze, not the deep-freeze cycling that cracks metal elsewhere, so most of what we find is wear from age and use rather than weather damage. It's a slower kind of failure, but it's steady, and it's exactly what you'd expect from hardware that's been turning since the Johnson administration.
