Types of deposits requiring chimney cleaning in NH

Chimney deposits can be found in a variety of forms but can be divided into three basic types as shown below:

Soot, since it is made of carbon, is combustible.

Soot is primarily composed of carbon particles but may also contain ash. Soot has a soft texture and will be black or brown in color. The flammability of soot will depend on the concentration of soot and ash. Ash is noncombustible.

Creosote is a by-product of incomplete combustion.

Creosote can be defined as a combustible deposit in the venting system which begins as condensed wood smoke including tar fogs and vapors. Creosote will be hard brown or black and form either curly, flaky deposits or even bubbly deposits in the venting system. Creosote is flammable.

Glaze is also the most difficult type of deposit to remove.

Glaze is a form of deposit that presents itself as a shiny, tarry substance. Glaze can form puddles or drop down and make formations that resemble black icicles. Glaze is the most dense type of wood burning deposit and, therefore, represents the greatest amount of fuel to burn in the event of a chimney fire.

There are several reasons to remove chimney deposits:

  • To ensure that the appliance vents properly to the outdoors.
  • To prevent chimney fires.
  • To reduce or eliminate chimney odors.
  • To remove blockages that could cause carbon monoxide gases to enter the home.
  • To prevent deterioration of the chimney interior caused by acids in the deposits.
