When water got on the floor and I pointed it out He asked if I had towels to clean it up, he then went out and got towels from the truck and put them on the ground. When he was finished he just picked them up and left the floor wet. I had to dry the floor. I have laminate floors and when they get wet they are ruined. All other workers I have had place floor protection down before they begin. The worker should have expected water would leak when changing a shutoff valve.
