According to the National Fire Protection Association (NFPA) standard 211, “Chimneys, fireplaces, and vents shall be inspected at least once a year”.
The Chimney Safety Institute of America (CSIA) also recommends regular cleanings when soot buildup has reached 1/8” build up or more.
The best way to know when it’s time to have your chimney swept is to schedule an inspection annually.
