I have used Clean Sweep Chimney & Stove for the last few years. Recently, they came out to do their annual cleaning of the chimney. The techs are always very clean around their work. They are fast and efficient. It is always very easy to set up an appointment and they are always on time. I highly recommend using Clean Sweep Chimney & Stove. I certainly will continue using them in the future. It is a great company!
