I purchased 48 feet of flex rod and a heavy nylon 6" brush so that I can clean my own chimney. I paid a sweep $125 last October to clean it and when I installed a flue in the pipe roughly two weeks later I found a one inch layer of creosote all around the pipe. I am unwilling to go up on my roof, and even more unwilling to get to the top of the chimney. My plan is to brush the pipe up to the cap from the hearth all while having a large trash bag around the base of the pipe. Is this a proper way to clean the pipe? Am I asking for trouble? Thanks for any help I might get. Bill
