One of the most common questions we get from people is “How often should I clean my chimney?” It is a great question because most people don’t know and knowing the answer to that question brings peace of mind. The Chimney Safety Institute of America recommends that no more that 1/4 inch of creosote should be on the walls of the flue. If 1/4 inch or more of creosote has build up than you should have your chimney sweep. It is a good idea to have your chimney cleaned every cord to a cord and a half of wood that you burn. A cord of wood can best be described as laying a 4 X 8 sheet of plywood on the ground and the wood is stacked 4 foot tall (about 2 truck loads of wood). Make sure you burn good seasoned wood like Oak or Hickory when at all possible.
