how often chimney sweep

Chimneys should generally be swept at least once a year to remove soot and creosote buildup, which are fire hazards. For wood-burning fireplaces, more frequent sweeping is recommended—typically twice a year or even quarterly if used heavily. If smokeless fuels are used instead, annual sweeping may be sufficient. Sweeping before the heating season and after periods of inactivity is advised for safety and efficiency. Professional chimney sweeps are recommended to ensure thorough cleaning and inspection.
