Creosote Accumulation and the Hidden Dangers of Postponing Service

Creosote removal is the chemical and mechanical extraction of highly flammable tar-like deposits that form inside flue walls during wood combustion. Every time you burn wood in your fireplace, smoke rises and cools against the chimney walls, leaving behind layers of black residue. the National Fire Protection Association (NFPA)|https://www.nfpa.org/)) establishes strict fire safety codes, noting that accumulated creosote is the leading cause of residential chimney fires. If you skip your autumn maintenance, that flammable buildup sits inside your flue all winter long, waiting for a stray spark to ignite an uncontrollable blaze.
