All You Need to Know about Glazed Creosote Removal

If you have a wood or oil-burning furnace or fireplace, you may have heard about glazed creosote. Information online, in the hardware store, and from well-meaning friends or loved ones may be confusing.

Chief Chimney Services has all the information you need to keep your home or business safe from glazed creosote.

What is it?

Creosote is a highly flammable, tar-like substance created when fuel is burned at high temperatures. This powdery residue can remain on the walls of a smoke box or chimney and compound over time in several layers. A professional will sometimes call this buildup glazed creosote, or level three creosote. At this level of buildup the creosote bubbles and boils when high-temperature fires burn in the furnace, then cools into a solid, very flammable, mass.

This hardened buildup can become a hazard as it begins to obstruct the chimney, causing the heat, smoke, and gases to slow, and begin to heat the flammable substance.

CSIA-Certified Chimney Technicians

At Chief Chimney Services, we are qualified, licensed, and insured to clean and repair damage caused by glazed creosote. Our licensed chimney sweeps are the difference in chimney maintenance. Using the proper tools we can transform the glazed creosote into a more pliable substance to be easily removed.

What We Do

The Chimney Safety Institute of America (CSIA) recommends regular chimney cleaning and inspections, and urges consumers to not depend only on chemical cleaning products like those found in hardware stores. A licensed and experienced chimney sweep provides fast service, inspections, and offers expert advice.

The way our chimney sweeps remove the creosote will depend on the consistency of the buildup. If it is gummy or moist we may use a chemical designed to transform the creosote to a powdery substance. This allows our sweeps to brush it out. These chemicals are safe for your home or business, and our chimney sweeps are qualified and experienced in their use. If a chemical remover isn’t needed, we use tools and brushes to detach the creosote from the chimney walls. After the creosote is properly removed, the chimney returns to safe function.

What You Can Do

As a home or business owner you can regularly check your firebox and chimney for signs of creosote buildup. Burning a high-temperature fire, with plenty of oxygen to the flames, helps the fuel burn completely. Also, burning proper fuel can help prevent creosote buildup. Proper wood should be cut and set aside to dry. This process could take as little as six months, or up to two years for denser types of wood.

Creosote is caused primarily when wood isn’t completely burned. So using improperly seasoned wood raises the risk of buildup.

In addition to burning proper fuel, home and business owners should not skip an annual cleaning and inspection. A regular cleaning should remove creosote before it reaches level three buildup.

Creosote in the Chimney

Dealing with Creosote Build-up inside the Home

What’s that black, shiny, coal-like substance that’s starting to accumulate in your chimney walls? That’s creosote and it can get thicker and thicker if not removed by a certified sweep. It can lead to bigger problems like negative air pressure and worse, a house fire. Here at Chief Chimney, we take this very seriously and encourage homeowners to have their chimney inspected annually. The safety, security and stability of your home is at stake and we want to make sure that you and your family get maximum enjoyment without having to worry about chimney problems.

Creosote forms naturally when you burn anything. However, you need to ensure that it is removed regularly to keep it from building up.

Creosote is the result of incomplete combustion of wood and coal products that eventually forms tar. The residue of smoke that comes out of it results in soot build-up or what we earlier identified as creosote.  It sticks to the chimney walls and in the chimney flues making it harder for air to exhaust out into the open via the chimney flue.

As experts we look out for these three things:

• The length of time creosote has been inside the chimney
• The thickness of the creosote
• The color, texture and odor of the creosote

Through this, we can determine the level of creosote. Once we know what level your creosote has reached, we perform the task of literally scraping them out by use of a specific, unique kind of brush that can thoroughly clean the inside of your chimney. However, if creosote has already become too thick, we can do weekly scraping to somehow lessen the thickness but completely getting it out of your chimney, unfortunately, is not possible. That’s why it is always important to have your chimneys inspected and cleaned annually (and more often if you use your fireplace often) to see if creosote has started to build-up in your furnaces.

With regards to your health, creosote definitely poses a threat. It can cause toxic air or carbon monoxide to fill the room and poison you — make sure you have a working carbon monoxide detector.

There are many ways for creosote to destroy your home but don’t allow it to happen. Call on us! We will remove and clean your chimney making it creosote-free.
