Median household income in Mount Pleasant runs $49,897, well under the $70,163 figure for the broader Columbia service area, and that gap is worth naming because cable repair pricing here isn't padded to match the higher-income side of the service area. A straightforward cable swap on a single door costs less than a full spring-and-cable job, and replacing both cables on a double door as a pair costs more than doing just one side - but it's the right call given how these doors age.
We don't give a number over the phone sight unseen, because a cable job that turns into a drum replacement or a bent track repair is a different estimate. What we can tell you is that a cable-only repair, with no other hardware involved, is one of the lower-cost calls we run.
