I called James to come over and he immediately called back and scheduled an appointment for the next day. He came in and did a phenomenal job with our three bedrooms and two area carpets for a really fair price. I would definitely recommend him to everyone looking for a true professional and nice guy. Unfortunately, my dog vomited all over one of the carpets a few days later. I called James right away and he's coming back over today. Great service!
