Have a fireplace? Each year there are approximately 25,000 chimney fires in the United States resulting in millions of dollars in damages and disrupted lives.  A neglected chimney collects a buildup of creosote along their walls. Creosote is a highly combustible material left behind when wood burns.  When this product accumulates into large amounts it is easily ignited when temperatures are high enough. To keep your family safe and warm ServiceMaster South of the James recommends you contacting a professional chimney sweep and have them inspect and clean your chimney.
