Why Do Chimneys Need to be Swept?
Chimneys need to be swept periodically because wood-burning creates soot and creosote. Creosote is a sticky glaze that results from incomplete combustion. Over time, creosote can build up on the walls of the flue and on the smoke shelf. If not removed in a timely manner, creosote becomes a fire hazard because it is highly flammable.

When Do Chimneys Need to be Swept?
It is recommended that all chimneys should be swept at least once a year. Overall, how often you'll need to have your chimney swept depends on how much you use it, how efficient the appliance is, and how quickly soot and creosote buildup in your chimney system.
The National Fire Protection Association (NFPA) Standard 211 states: "Chimneys, fireplaces, and vents shall be inspected at least once a year for soundness, freedom from deposits, and correct clearances. Cleaning, maintenance, and repairs shall be done if necessary."
