Is there a simple fix to creosote build-up in your flue? Do chimney sweeping logs work as well as they claim? The answer is yes and also… no.
On a cold winter’s day, there is nothing like warming up in front of a crackling wood fire. However, over time, burning wood in a fireplace can potentially lead to a build-up of creosote in the flue (which can be highly flammable). In fact, creosote build-up is a significant cause of house fires in Canada. Therefore, it is vital that fireplace and woodstove systems are regularly inspected and cleaned to keep you and your family safe.
So, what about chimney sweeping logs? Are they effective? Are they all you need to keep your chimney clean and free of debris? Chimney sweeping logs do work somewhat. These logs contain a chemical catalyst that has shown to reduce early-stage creosote build-up by up to 60% with repeated use. But, can these logs replace a professional chimney cleaning? Absolutely NOT!
A chimney cleaning that is performed by a licensed professional goes well beyond the results produced by a chimney sweeping log. A professional sweep removes the highly combustible creosote that chimney sweeping logs cannot. Many chimneys are constructed with elbows that allow creosote to sit and collect. Only a chimney brush can remove these deposits. Further, debris falls and collects on smoke shelves, baffles, catalytic combusters, etc. and this debris needs to be removed to ensure the proper functioning of the wood burning system. Also, flues frequently contain animal nests, leaves, and other debris that can create a hazard by blocking the flow of emissions from the wood burning appliance.
Another benefit to hiring a professional sweep on a regular basis is that they conduct an inspection which could reveal potentially hazardous situations in your wood burning system. Typical hazards include breaks or breaches in the flue, blockages, tar-like creosote build-up, chimney structure instability, etc. Regular cleanings can alert you to problems before they become dangerous.
