How often should you have your chimney swept?
Once a year.
Best month: August (Northern Hemisphere)
Only some homes need this one. It is optional on the checklist and starts switched off in the tracker.
How to do it
Have a certified chimney sweep inspect the chimney and flue every year, and sweep it when the inspection finds creosote or blockage.
Why it matters
Creosote buildup is the main cause of chimney fires.
Recommended interval: once a year, per Chimney Safety Institute of America (citing NFPA 211).
General guidance for a typical home; the manufacturer's instructions come first.
