This was my first time using Steven's Chem-Dry Carpet Cleaning. I know they do not use water to clean the carpets and they did dry quickly after the carpet technician was finished. I was a bit disappointed in the results of the stairs leading into the basement, they did not come clean at all. I am going to wait a few more months and give them a callback and have them come out and try again. The carpet technician was on time for my appointment and was kind and considerate, I just think that the carpet could have been cleaned better.
