Comment: We had two rooms to be cleaned, both the "victim" of a diabetic cat I'm sure was getting back at us for restricting her diet by peeing on the floor. We tried cleaning the spots with things recommended by Carpet One, with no success, so the man there suggested Dalworth. We thought the young man was excellent...until this morning when we noticed some spots in one of the rooms that look like they hadn't been touched. I know he worked in that room, but didn't watch him. The spots look much like some he DID remove, so I'm wondering why it wasn't possible to at least lighten them. Five hundred dollars is a LOT to pay for something that still looks like it needs to be cleaned!
