We believe that if you are going to spend valuable money it should be on assuring your home or facility stays clean and not on outsourcing your cleaning needs. With fast success in NH performing commercial floor cleaning, Clean Sweep expanded its operations to also include industrial and residential cleaning to its list of services. Within the short few years of operations we have developed many valued customers in a wide variety of markets and have gathered a team of experienced and professional cleaners for all service types.
