Flue cleaning is the process of removing soot, debris, and creosote buildup from the flue of a chimney or venting system. This is important for maintaining safe and efficient operation of heating appliances, such as wood stoves, fireplaces, and furnaces. Regular cleaning helps prevent chimney fires and ensures that harmful gases can escape properly. During a flue cleaning, a professional chimney sweep uses specialized tools to scrub the interior surfaces of the flue. They may also inspect the chimney for any damage or blockages. It is recommended to have flue cleaning done at least once a year, especially before the heating season begins.
