To put it plainly, creosote is the residue of fires that sticks to the inner wall of the chimney. It is a result of chimneys that have the job of expelling the by-products of combustion – the substances produced when wood burns. These include smoke, water vapor, gases, unburned wood particles, hydrocarbon, tar fog and assorted minerals. As these substances exit the fireplace or wood stove, and flow up into the relatively cooler chimney, condensation occurs. Thus creating creosote.

Creosote build up is one of the reasons why it is important to have your chimney cleaned regularly, because this crusty or flaky, tar like black stuff is highly flammable. It is important to have a certified chimney sweep regularly clean and inspect your chimney to avoid chimney fires.
