Chimney Sweeping Certificate

A Chimney Sweeping Certificate confirms that a chimney or flue has been swept and inspected by a qualified chimney sweep. Regular sweeping prevents chimney fires and carbon monoxide poisoning. Insurance companies often require proof of annual sweeping for properties with open fires or wood burners.
