CREOSOTE: THE FIRE HAZARD HIDING IN YOUR FLUE
Creosote is a flammable byproduct of burning wood that coats flue walls. Advanced glazed creosote is especially dangerous; chimney fires contribute to 25,000+ U.S. house fires annually.
Warning signs include dense, dark smoke; unusual heat from the chimney; loud cracking or popping; flames or sparks visible at the chimney top; and a strong hot-burning smell.
NFPA 211 recommends annual professional chimney inspection and cleaning for chimneys in service. Schedule yours before fall’s first fire.
Home inspectors document visible firebox, damper, cap, and crown conditions when accessible. Full flue-interior evaluation requires a certified chimney professional. Never attempt DIY flue cleaning.
