Very helpful, they were able to come to our house right the second day after we did the call. We have basement carpet and 3 other bedrooms carpet . I am so pleased with their service, the carpet had a lot of dark stains and tough dirt all over, including paint stains and wax. after they cleaned it retrieved the original colour. Honestly I was not expecting to find the carpet again that much clean. They definitely use a good product and provide good service. Highly recommend them.
