How to Remove Glazed Creosote from Chimney: Everything You Need to Know

How to remove glazed creosote from chimney

Creosote buildup is one of the signs of a chimney fire. It could mean that your chimney experienced a fire, and you didn’t realize it. But, it could also be a potential hazard. For that reason, it’s vital that you know how to remove glazed creosote from chimney.

Having a chimney is a great responsibility as you have to be on top of its maintenance. Your chimney won’t work properly if you don’t give it proper care. So, when talking about creosote, you have to pay close attention if your chimney has high buildup levels.

We invite you to read our blog to learn more about this byproduct. We will discuss what causes glazed creosote and its three forms. Also, we will talk about how to remove and prevent it.

What Is Creosote?

So, what exactly is creosote?

Creosote is a byproduct of wood burning. When you burn wood, you expect it to burn completely. But, this may not happen if there is no proper air flowing to your fire. This inadequate airflow starves the fire, which leads to your wood not burning completely.

The wood that wasn’t completely burned has oils that travel through the smoke produced by the burning. As the smoke rises, it starts to cool. Finally, it condenses with water and other chemicals on your chimney’s flue. This is what we know as creosote.

What Causes Glazed Creosote in Your Chimney?

Unseasoned firewood causes glazed creosote

As we said before, creosote results from wood burning. But, the amount of creosote is small if you use the correct type of wood to burn in your fireplace.

So, what causes high levels of creosote buildup?

The first cause of creosote is a smoldering fire; this fire burns slowly with smoke but no flame. This produces less combustion, which results in more creosote.

Another cause of creosote buildup is burning wood that is not seasoned. In fact, green wood is that type of wood that fills up a chimney with creosote most quickly.

What Are the Three Forms of Creosote?

Use creosote remover to get rid of glazed creosote

There are three forms, levels, or degrees of creosote. When you have a professional come and clean your chimney, they should be able to recognize the type of creosote.

1st-degree creosote is the easiest to remove.

2nd-degree creosote will look like shiny, hard, black flakes.

3rd-degree creosote is the most difficult to remove. This type of creosote is what we know as glazed creosote.

How to Remove Glazed Creosote from Chimney?

To know how to remove glazed creosote from a chimney, you’ll need more than a chisel. You’ll have to buy a creosote remover that will not damage the chimney. An alternative to removing glazed creosote is to replace your chimney liner.

How Can You Prevent Glazed Creosote?

The best way to prevent glazed creosote from sticking to your chimney is only to fire seasoned firewood. If you stop burning unseasoned firewood, then you’ll notice how your chimney produces less creosote.

Proper chimney maintenance can also help prevent glazed creosote. By having regular chimney cleaning, you’ll reduce the amount of creosote buildup. Also, it’s vital that you schedule annual chimney inspections. This will allow you to tell if you need chimney repair or sweeping.
