Chimney sweep is needed to remove creosote deposits, animal nesting and other debris from chimneys and vents. Creosote buildup in chimneys can lead to chimney fires or flue blockages and cause dangerous fumes to be forced into your home. During a chimney fire temperatures inside the chimney often exceed 2000 degrees and this can destroy your chimney and may set your house on fire. When first moving into a home, or before using a chimney or fireplace for an extended period of time, it is crucial to have a complete Chimney cleaning and inspection prior to lighting the first fire of the season.
