The Dining Hall dish room floor was badly in need of replacement. To replace it, we had to take everything out: the dishwasher, wash sinks, and the whole assembly line. After that we broke up all the tile and found an unwelcome surprise. Because the tile was falling apart before we replaced it, it has been leaking for years into the subfloor, causing it to rot and mold and even leaking into the laundry room below. We got all the subfloor replaced and prepared it for the new flooring.
