Every chimney should be swept at least once a year. Annual sweeping removes soot, debris and blockages, confirms the flue is clear and drawing correctly, and satisfies your home insurance requirements.
If your stove or open fire is in constant use throughout the winter, quarterly sweeping is recommended. Heavy use means heavy soot buildup — and soot buildup means chimney fire risk.
Burn dry. Sweep annually. Stay safe.
