Creosote is often mentioned when discussing chimney concerns, but most of you are wondering, what is creosote? You might know by now that creosote is bad, but that’s usually where the knowledge of creosote begins and ends. It is important to know what we are talking about when discussing creosote and how to avoid it in your chimney.   

What is Creosote?  

Creosote mainly consists of tar produced when you burn wood inside your fireplace. When your fireplace is hosting a fire, smoke rises from the flames and creates creosote when mixed with cold air. This tar substance builds up as it sticks to the chimney liner or brick. It poses a safety hazard because it is very flammable, and the more creosote present in your chimney, the greater the risk of a fire.   

Creosote also never goes away, but instead, it grows. It coats the chimney flue, which creates a narrow passageway for smoke and additional creosote. If left untreated, it can build up and completely block the chimney flue, possibly causing a house fire, or at the very least, it can make the chimney unusable.   

How to Avoid Creosote in your Chimney   

There is no way to completely avoid at least small amounts of creosote in your chimney, but it’s only problematic when there’s a creosote build-up. Since build-up happens when your chimney is not properly ventilated or regularly cleaned, those are two simple ways to reduce creosote build-up. The safest and most reliable way to get rid of creosote is to call the professionals. It is not completely impossible to remove creosote yourself, but it is not safe for the average person to execute the removal. Creosote causes many health concerns, including irritated skin and eyes, respiratory issues, and possibly even cancer if improperly exposed. You will avoid exposure to creosote if your chimney is cleaned at least once a year by a professional  

Creosote Stages and Removal Process   

Whether your creosote build-up is standard or more severe, it is important to leave the removal process to the professionals. There are three different stages of creosote build-up, and each is more severe. Stage 1 creosote build-up is when small amounts are present, and the texture closely resembles soot. It is thin and flaky with a shallow coating that is easily removed with the right equipment. Stage 2 creosote build-up is when more residue is present, and it is a thick tar instead of just soot. There is usually quite a bit more present, and it is a harder texture that is more difficult to remove. Removal at this stage usually requires chemicals and heavier machinery than a standard metal brush. Stage 3 creosote build-up is when a significant amount of creosote is present, and it is heavily concentrated in certain areas. The creosote at this stage is hard, sticky, and oily, making it even more difficult to remove.
