I would use this service again if I could afford the full price, and that's why the 'B' overall . The other reason I rank them a 'B' on professionalism, and this is true of many kinds of repair/remodel people that come into your home, is their boots are dirty from other jobs, etc., and they don't put covers on them or take them off. So that is a general comment, not just this service. Once they've cleaned a drain, they are standing in the shower running water to make sure everything works, what do you think is going to happen next? The floors and carpets get dirty from the wet, dirty boots and then it's clean up time for you. That's exactly what happened. My hallway carpet has to replaced because of a bathroom remodel. Be sure to ask them when they arrive, most have the boot covers in their trucks. Otherwise they are professional.
