Creosote is highly combustible. It develops when wood is burned at a low temperatures, and the oils in the wood cause an incomplete combustion. The smoke begins to rise through the chimney flue and as it is cooling down it causes moisture. This moisture and soot condense together to the interior surface of the chimney. A residue develops that sticks to the inner walls of the chimney, which is creosote. Creosote can be black or brown in color, and it can be flaky and crusty in appearance. It is a tar-like substance that is sticky or hardened, depending on its age. Creosote is highly combustible, and if the creosote builds up, it can ignite quickly causing a chimney fire. This could result in a house fire if the creosote buildup isn’t removed. It is very dangerous and many homes have become engulfed in flames due to a fire in the chimney, which was due to creosote buildup. Creosote can be easily removed. A professional chimney sweep can clean the chimney and remove all creosote from a chimney. If the chimney liner is deteriorated due to creosote buildup then a new chimney liner should be installed. A chimney liner is the heart of the chimney and should be maintained. ChimFab is the leading supply company in Connecticut for chimney liners. We offer a variety of liners along with kits.
