We are building a new house, and we were discussing the design of a masonry chimney with the mason who is doing the work. We decided to go with a closed, for lack of a better term, "masonry chimney cap" and he mentioned that he would morter in a mesh to prevent animals from entering. After asking him how we were going to clean the chimney, he sort of chuckled and mentioned that cleaning the chimney isn't necessary with modern chimney designs. I believe he was referring to the flu spacing that brings the chimney further away from the house. Furthermore he mentioned that we should occasionally burn some pine to burn off any of the creosote.
Is there any truth to this?
