It only flooded because the floater sensor in the sump pump got stuck one time, so it didn't realize it needed to suck up the water, it wouldn't have flooded otherwise. We rented a dumpster and tossed most of what was in the basement (various things were on shelves or in the elevated crawlspace and didn't need to be tossed, like my old NES games), ripped out the carpet, and hired a mold remediation company that ripped out the bottom two feet of our drywall. And we will replace the sump pump soonish, although it hasn't had a problem since. It's fine down there now. Wasn't cheap to get it to that point, though. Especially since our insurance company doesn't cover sump pump failures unless you have a specific rider, which apparently we didn't have. Still might not be good enough for you, and that's fine. But I suspect you wouldn't notice if you went down there and didn't know it had once flooded beforehand. About the only telltale thing down there is a bump here and there where the seam of the bottom two feet of the new drywall is.
