We have the newest Snap lock rotary cleaning system, This system combines spinning plastic whips combined with chains and stainless-steel cables depending on the level of creo-soot. This system dose a far better job cleaning all kinds of creo-soot buildup than the old brushes. Sweeping can be done from bottom or top of chimney. Included in the chimney sweep we always do a video inspection of the liner to confirm cleanliness of the liner and integrity for safety.
