When you have a fireplace in your home, the most essential maintenance step you can do is hire a professional chimney sweeping company, such as Weststar Chimney Sweeps, to perform an annual cleaning of your chimney. This task ranks high in importance, as annual chimney sweepings prolong the life of your chimney as well as ensure the safety of your fireplace and chimney. The Chimney Safety Institute of America (CSIA) has published The Homeowner’s Guide to Chimneys, Fireplaces, and Woodstoves to provide helpful information for understanding how these heating systems work and how to properly maintain them. We would like to share some facts from this guidebook with you to help you understand why annual chimney sweepings are so important.
Removal of Chimney Deposits
According to the CSIA, there are three types of deposits that build up on chimney walls:
- Soot — Primarily composed of carbon particles and possibly ash remnants, soot can be highly flammable, depending on the concentration of soot and ash. Since ash is not combustible, a higher ash content in soot reduces its flammability.
- Creosote — Naturally formed during the condensation process, creosote is a highly flammable residue of the by-products of incomplete combustion. Varying in its appearance, creosote can be black or brown, hard and shiny, sticky and tar-like, or crusty and flaky. No matter what it looks like, creosote deposits are hazardous as they are one of the main causes of chimney fires.
- Glaze — The most difficult deposit to remove, this shiny, tarry substance creates a large amount of fuel to burn and poses a serious danger of a destructive chimney fire.
Removing these deposits is the major reason for annual chimney sweepings. Preventing chimney fires, eliminating chimney odors, ensuring proper venting to the outdoors, removing blockages that could cause toxic gases like carbon monoxide to enter the home, and stopping deterioration to chimney walls from the acids in these deposits are all accomplished during a professional chimney cleaning by removing buildups of soot, creosote, and glaze.
Discovering Essential Repairs
Another important reason to have your chimney swept once a year: CSIA-certified chimney sweeps, including our staff at Weststar Chimney Sweeps, will look at the exterior of your chimney for loose bricks and mortar and other signs of water penetration damage, examine the condition of your flue liner to check for cracks and deterioration, and monitor the venting system of your chimney to ensure the toxic by-products of combustion are exiting through the chimney. When we find any needed repair work, we can fix it for you. We specialize in crown repair, resurfacing, repairing, or replacing damaged flue liners, water leak repair and prevention, and customized repair or replacement of flashing where your chimney meets the roof.
While an annual chimney cleaning generally is sufficient to keep your fireplace and chimney safely maintained, more frequent chimney sweepings should be scheduled under certain conditions. The number of cleanings needed depends on the amount of time your fireplace is used, the installation of your fireplace, the type of fuel used for your fires, and your burning habits. Our chimney sweeps can tell you if your chimney needs to be cleaned more often than once a year.
