What Is Creosote?

When wood burns, it produces creosote, a highly flammable substance that accumulates in your chimney. It is a black or brown, tar-like substance that can accumulate inside your chimney over time. Creosote is dangerous because it can ignite easily, leading to a chimney fire that can quickly spread to your home.

Stages of Creosote Buildup

Creosote buildup occurs in three stages:


  • Stage one, creosote is a light, flaky substance that a chimney cleaning professional can easily remove.
  • Stage two, creosote is thicker and harder, resembling a layer of tar. It requires more work to remove and can be a significant fire hazard.
  • Stage three is the most dangerous stage of creosote buildup. It is a hard, shiny glaze that is virtually impossible to remove without professional help. It is also the most likely to ignite, causing a chimney fire.

What Causes Creosote Buildup?

Creosote buildup occurs when wood is burned inefficiently. Factors that can contribute to creosote buildup include:

  • Burning unseasoned or wet wood.
  • Having a dirty or clogged chimney.
  • Not allowing enough air to flow into the fireplace.

Why Is It Dangerous?

Creosote is dangerous because it is highly flammable and can ignite easily. A chimney fire caused by creosote buildup can quickly spread to your home, causing extensive damage and putting your family at risk.
