I called Sherman's to get a quote - and he offered me a deal for $250 to do tile and grout cleaning and chem dry carpet cleaning on a 1200 square foot house. This is a great deal! The service technician was on time (early) and finished in under 2 hours. The tile looks fabulous! The carpet....not so much. It looks the same as before they came. I mentioned it to the service tech and he said that some of the dark spots would fade as it dried. I went back to the house the next day and the stains and dingy high traffic areas looked the same. I called Jason - the owner and told him about this. He quickly told me he would have the service tech contact me and abruptly ended our conversation. I never heard back from either one of them. I think the results of the carpet have to do with the chem dry method itself, not necessarily due to this company specifically. Still, I appreciate good customer service. Don't tell me you're going to have someone contact me and then drop the ball. You should be concerned about customer satisfaction and follow through.
