It matters who cleans your carpet. Most carpet manufactures recommend the hot water extraction/steam clean method. And in fact, may require proof of periodic cleaning using this method in order to keep from voiding your carpet warranty. Using this method with our Bane-Clene® equipment, you can be assured that your carpet will be left as clean as possible. We charge by the square foot and not by the room - so you are paying only for what you are getting cleaned and not overpaying for what is not cleaned.
