The Chimney Safety Institute of America (CSIA) says that fireplaces need to be cleaned when there is 1/8″ of sooty buildup inside the chimney or flue system. Since homeowners may not be able to judge the condition of the system, it is advised that a professional Chimney Inspection be done by a member of the National Chimney Sweep Guild (NCSG)*. This will determine whether a chimney cleaning is needed. When any glaze is appearing in the flue, cleaning should be done immediately. This glazing is a dangerous state that is susceptible to combustion. When an accumulation of soot and creosote occurs it can fuel a chimney fire that will likely damage the chimney. Many chimney fires that start this way can spread to the roof and home.

The National Chimney Sweep Guild recommends to have your chimney inspected once a year.
