We Specialize In Glazed Creosote Removal

One of the most dangerous substances to have in your chimney system is glazed creosote (also known as level 3 creosote). This tacky or crusty residue results from incomplete combustion and neglect. You see, any time wood burns in the fireplace or stove, it releases byproducts, which the smoke carries up and out of the flue. When these byproducts cool before exiting the chimney system, they settle along the flue in the form of creosote. If the chimney is not regularly swept, creosote builds up, layer upon layer, forming glazed creosote.

Although standard chimney sweeping tools can be used to remove regular creosote, glazed creosote removal demands a different approach. When we encounter glazed creosote, we use specially formulated chemical products to break down the glaze so that it can be safely removed.

The reason we work so hard to safely remove glazed creosote from the chimney is that, if left alone, glazed creosote can be a serious threat to both home and homeowner. Some of the things that result from glazed creosote include the following:

  • a fast-spreading and dangerous chimney fire
  • restricted air flow (which leads to appliance inefficiency and carbon monoxide/smoke back flow)
  • chimney flue corrosion and damage
  • more creosote!

If you live in Calvert, Charles, St. Mary’s, or southern Anne Arundel or Prince George’s county and have glazed creosote inside of your chimney, we can help. Our team uses professional-grade products that work to effectively remove glazed creosote, without compromising the integrity of your chimney system.

What Can You Do To Prevent Glazed Creosote In The Future?

Good news: there are some things you can do to prevent the development of glazed creosote in your flue:

  • Only burn seasoned firewood. Wet firewood will produce more creosote.
  • Make sure the damper is completely open before starting a fire in your fireplace.
  • Make sure your flue is appropriately sized for your appliance. If you aren’t sure whether your flue and appliance are a good fit, a Chimney Safety Institute of America (CSIA)-certified sweep can help.
