On Duty Chimney Sweep was a very professional and knowledgeable. Cleaned chimney with state of the art equipment, but also had to remove remnants of a brush left by the last person who cleaned chimney (which caused a fire). Bryan inspected the chimney and advised me of its condition after the fire. He found no fire-related damage and gave a complete accounting of what residues and quantities thereof that he found inside the chimney -- invaluable information to those of us who heat with wood; it tells us how efficiently and safely our system has been running. He conducted what is a very messy trade in a meticulous manner, covering surfaces and cleaning up completely after each operation: chimney, flue, and cleanout trap.
