DEAR BARRY: We sold our house a few months ago and signed a disclosure statement that said no water problems existed. But the new owners found carpenter ants in a closet, which led them to rip off the drywall and remove the hardwood flooring. What they found was rot in the wall. No one could have known about this rot, but the new owners say we should have seen water stains on the subfloor when we installed the hardwood flooring last year. We don’t recall any stains or we would have disclosed them.
