At the IICRC, we believe that the best way to maintain a cleaner and healthier home is to augment your regular cleaning and vacuuming with periodic visits from an experienced certified professional. For those tasks that require a specialist � such as carpet and upholstery cleaning, stain removal, and maintenance of wood and tile floors � only a certified technician will deliver the results you can trust.
