Lords Chimney - Chimney Sweep and Fireplace Vent Service

If you walk down the aisles of your neighborhood big box home improvement store, you are bound to see a wide variety of products designed to help homeowners clean and maintain their fireplaces. While some of these products can be useful, they should not be used to replace regular annual chimney maintenance by a certified chimney sweep.

One such product that our customers regularly ask about are “chimney cleaning logs”. Sold for less than $20 at many home improvement stores, chimney sweeping logs advertise their ability to significantly reduce creosote buildup in the chimney. Because of this, some homeowners purchase and burn these products as their only form of chimney maintenance, patting themselves on the back for saving money on a chimney sweep.

Despite their advertising claims, these logs are no replacement for a professional chimney cleaning. Although they may be able to remove some creosote buildup, there are a number of ways that they are deficient at maintaining the health and safety of your fireplace system.

Why loosening creosote is just part of the job

The primary purpose of a chimney cleaning log is the removal of creosote; the smoke from the log loosens the creosote and causes it to fall down the flue and into the firebox, where it can be safely swept up and removed.

In theory, this is an excellent system. Unfortunately, the reality leaves much to be desired.

Most flues are not a straight vertical line between your firebox and the top of the chimney. Depending on your fireplace’s location, your flue may have one of more curves and bends in it. When this happens, the loosening of creosote by the chimney cleaning log merely causes it to fall and accumulate in the bends of the flue. This may not only block the flue, but can also create a significant fire hazard. Even fireplaces without curved flues may wind up with the majority of the creosote trapped on the smoke shelf, which can be difficult to access and clean without proper training.

A chimney cleaning log is no substitute for a chimney sweep

While a chimney cleaning log may be useful in loosening creosote, it is no substitute for the services performed by a certified chimney sweep.

“I usually tell people using one of those logs instead of having your chimney cleaned manually is like chewing Dentyne instead of brushing your teeth,” said Allan Bopp of Bald Eagle Enterprises. “It may help a little, but it’s a poor substitute for the real thing.”

Likewise, a chimney cleaning log has no way to know or tell you if your chimney is damaged in any way. There are a number of hidden issues such as cracked flue liners, decaying masonry, or damaged chimney caps or crowns that can only be spotted by a sweep during a chimney inspection. Because many of these chimney issues do not affect performance, you may have no idea there is even an existing issue.

Don’t trust the health of your chimney or the safety of your family to a $20 log bought at a big box store. Instead, have an annual chimney sweeping and rest assured that you can safely use your fireplace for the rest of the year. Contact Lord’s Chimney today to schedule an appointment!
