What Is Creosote Deglazing?

One of the biggest reasons why you need to have your chimney professionally swept every year is to have all of the creosote that has accumulated on the walls of your chimney removed. A natural compound that develops during the combustion process of burning wood, creosote is so flammable that the Chimney Safety Institute of America (CSIA) has named it as a leading cause of chimney fires. Usually, a professional chimney sweeping will remove all of the creosote from your chimney, but sometimes the creosote can build up so badly that it turns into a glaze that coats the chimney walls that cannot be removed by a typical chimney sweeping. Weststar Chimney Sweeps knows what to do in this type of situation to get all of that glazed creosote out of the chimney. We would like to tell you more about our creosote deglazing services.

A detailed mechanical cleaning, creosote deglazing is the process we use to remove creosote that has become baked onto your chimney walls. Weststar Chimney Sweeps uses special tools, including a high-speed half-inch drill and a 24-inch wizard whip, to break down the rock-solid glazed creosote and remove it from your chimney. Standard chimney sweeping tools are not powerful enough to do this task correctly.

How did the creosote become glazed in my chimney?

Creosote buildup happens in three stages. In the first stage, the creosote has a fluffy and velvety texture, and in the second stage, it becomes flaky and crumbly. When creosote reaches the third stage, it turns into a shiny, black glaze that coats the inner chimney walls. Although creosote is a natural and expected residue of burning wood, the third stage of creosote usually occurs due to user practices, especially burning unseasoned wood. When you burn wood that has not been allowed to dry sufficiently, the fire burns at a lower temperature because it is spending a lot of energy drying out the moisture in the wood. A cooler fire can accelerate the development of creosote, which can lead to creosote glazing. Another user error that allows creosote to glaze is not opening the damper completely during a fire, as this allows the fire to smolder. Installation errors can also encourage the development of glazed creosote. Newer fireplace inserts are typically much smaller than masonry chimneys and need professional installation to work properly. Weststar Chimney Sweeps can install a stainless steel chimney liner to provide a correctly sized flue for your insert. This will prevent the drafting problems that can lead to glazed creosote on your chimney walls.

What Is Creosote Deglazing?

When our Chimney Safety Institute of America (CSIA)-certified chimney sweeps from Weststar Chimney Sweeps clean your chimney, we take great care to remove every bit of creosote from its interior walls. However, sometimes it takes more than just a typical chimney sweeping to get rid of this flammable residue. Creosote evolves through three different stages, and when it gets to the third and final stage, it becomes glazed on the walls of your flue. Glazed creosote can be very difficult to remove because it is like a thick shell of chocolate stuck to your chimney walls. It is impossible to remove with our regular chimney sweeping tools, so we will need to give your chimney a professional and detailed mechanical cleaning. Creosote deglazing is very important to keep your chimney safe from dangerous hazards, and we would like to tell you more about this service and why it is so essential.

What exactly is creosote, and why is it so hazardous?

A compound that forms naturally during the combustion process of burning wood, creosote sticks to the inner walls of your chimney and can accumulate into large deposits. If these deposits become large enough, they can block your flue and even ignite a chimney fire if the internal temperature of your flue reaches a high enough point. As the CSIA says, chimney fires can be caused by dirty chimneys. This is why the CSIA and other national fire safety organizations recommend that a chimney should be professionally swept annually.

What causes creosote to become glazed?

Although creosote occurs naturally when you burn wood, there are some precautions you can take to keep it from reaching the glazed state. The most important thing you can do to prevent glazed creosote is to always burn only seasoned wood, or wood that has been dried for at least six months. When you burn freshly-cut, wet wood, your fire burns at a lower temperature because it is too busy trying to burn off all of the excess moisture. This cooler temperature causes more creosote to form and dry at a slower pace. New layers of creosote begin to form over layers that are still wet, which leads to the development of glazed creosote. Another important thing to always do when you use your fireplace is to be sure the damper is completely open, which prevents the fire from smoldering and producing more creosote.

What is a creosote deglazing?

A detailed mechanical cleaning, creosote deglazing involves our trained technicians using a mechanical high-speed, half-inch drill and a 24-inch wizard whip to be able to safely remove the glazed creosote by breaking it down so that it will not damage the interior walls of your chimney.
