What is Creosote?

Creosote is a carbon material naturally created during wood and fossil fuel combustion. When the distillation of tar mixes with air and moisture, it leaves a light ash-like coating known as creosote. Draft problems that result in incomplete combustion can produce more creosote in the flue. There is an increased risk of a chimney fire the longer it remains in the flue.

1st Degree Buildup

In this stage, the creosote is a grayish ash-like coating that is relatively easy to remove with a standard chimney brush. However, failure to properly sweep the chimney regularly will cause the buildup to continue, leading to 2nd and, ultimately the most dangerous type, 3rd-degree buildup.

2nd Degree Buildup:

In this stage, the creosote is starting to harden into dark tar-like flakes with a hard, shiny surface. It’s a little harder to brush away, so it takes longer to remove. The hardened tar is also flammable, which increases the risk of a spark starting a chimney fire.

3rd Degree Buildup:

This is where the creosote has hardened into a thick, tarry, crusty material that can cover the flue lining, interior walls, damper, and other components. It is also highly flammable and complicated to remove without professional help. All it takes is a spark from a hot ember to ignite the creosote causing a devastating chimney fire that could spread throughout the house, resulting in extensive property damage and even endangering the lives of those residing in the home.
