If you use your fireplace often, you might notice that at times it doesn’t work as well as it once used to. This can be due to the buildup of creosote. This is a common problem that can be extremely harmful to your chimney system and the house. Here’s everything you need to know about creosote:

So, What Is Creosote?

When burning softwoods for a long period, the chimney walls tend to get covered with a dark, tar-like substance that’s greasy to the touch. You may think of this as soot, but it’s actually a hazardous chemical compound that results in several health complications for residents if not cleaned regularly. This black residue is called creosote and can cause structural damage to your home.

The Different Stages of Creosote

The creosote in the chimney goes through three different stages. These are:

Stage 1 – This is the initial stage when it’s a flaky deposit. You can easily brush this away with the right tools.

Stage 2 – Over time, this loose deposit builds up and becomes difficult to remove. A professional may require a special scraper or brush to remove it.

Stage 3 – This is also known as creosote. If the chimney isn’t cleaned regularly, the creosote hardens and even brushing, and scraping can’t help. This stage can be dangerous as it can increase the risk of a flue fire.

How Can Creosote Damage The Chimney?

  1. Fire

One of the most obvious damages is a fire. Sometimes a small fire may go unnoticed by homeowners, which can build up over time. If there’s enough creosote inside the chimney, the fire can be massive and pose a health risk to all members present in the house and those nearby.

  1. Carbon monoxide 

Creosote causes an airflow blockage, which prompts dangerous carbon monoxide to enter the house when the fire is burnt. If the chimney is not cleaned, there’s a high chance that the vent is blocked, making it more problematic. CO is odorless and colorless, making it even more difficult to detect.

  1. Erosion

Creosote is acidic, leading to erosion of the chimney liner and other internal materials. If ignored, this can lead to expensive repairs in the long run.
