Creosote is a sticky mix of tar, soot, and condensation that forms inside chimney liners when wood burns. It is highly flammable and one of the main causes of chimney fires.
“Seasoning” wood means drying it out properly before burning it. Freshly cut (“green”) wood contains a lot of moisture — often 40–60% water. Seasoning reduces that moisture so the wood burns hotter, cleaner, and safer.
Tips to avoid a fire inside your chimney. Common causes Infrequent chimney cleaning Burning wet or unseasoned wood Poor airflow or ventilation Blocked flues Excessive soot and creosote build-up
