How Do Chimney Sweeping & Annual Inspections Reduce Your Chance of a Potential Fire Hazard?

Inspecting your chimney & appliance before having your first fire of the season

The fall months are just beginning, with winter not far behind. As temperatures begin to drop, it may be tempting to build the first fire of the season in your fireplace or woodstove appliance. However, before you think about building that fire inside your home, it is always important to take safety precautions first, such as chimney inspections & necessary sweeping. The CSIA (Chimney Safety Institute of America) and the NFPA (National Fire Protection Association) state that you should have your chimney inspected annually and cleaned as necessary by a CSIA Certified Chimney Sweep.

It is essential that you inspect the chimney for any potential fire hazards. You should always hire a CSIA Certified chimney professional to perform the chimney inspection. If you don’t take the time to thoroughly check the fireplace, flue liners & appliances along with your chimney’s flue liner, you’re running the risk of your chimney catching on fire or, even worse, your entire home. Chimney sweeping & inspections can go a long way to preparing your fireplace for the cold months ahead, so let’s go over some of the ways chimney sweeping can help to reduce fire hazards.

Creosote Buildup is a Hazard

Fireplaces and wood stoves are designed to safely contain wood-fuel fires while providing heat for a home. The chimneys and flues that serve them have the job of expelling the substances produced when wood burns. These include smoke, water vapor, gases, unburned wood particles, hydrocarbon, tar fog, and assorted minerals. As these substances exit the fireplace or woodstove and flow up into the relatively cooler chimney, condensation occurs. The resulting residue that sticks to the inner walls of the chimney is called creosote.

Chimney Sweeping and Creosote

Chimney & Rotary sweeping is critical to remove the flammable creosote from the chimney. If the temperatures reach high enough within the chimney and if the creosote is thick, it can quickly catch on fire, which will begin to spread. 

The number one leading causes of home fires are directly from heating appliances. It is always ideal to sweep & inspect a dirty chimney after its last use of the winter season. Moreover, it is also equally important to inspect the chimney before its first use of the winter season. By doing this, you can reduce the risk of a chimney or structure fire.
