Do Chimney-Cleaning Logs Really Work?

Chimney Cleaning Logs in Amherst, NHThe fact that there’s such a product as chimney-cleaning logs tells you that cleaning built-up creosote out of chimneys is an important job. Chimney-cleaning logs are burned like any other logs but have special ingredients that are said to remove creosote. Sounds easy and simple. But do the logs actually work?

Look for CSIA-approval

Just because a product calls itself a “chimney-cleaning log” doesn’t automatically mean it will do a good job. Some brands bear the inscription “CSIA Accepted Product.”  CSIA stands for the Chimney Safety Institute of America, the leading agency covering chimney safety and the hearth industry in general.

If you’re going to try chimney-cleaning logs, definitely purchase those accepted by the CSIA. But you may notice some other wording from the institute on the log label that states something to the effect of: these logs are not a substitute for annual chimney inspection and cleaning.

Drawbacks to chimney-cleaning logs

Because these logs cannot replace cleaning performed by CSIA-certified chimney sweeps – technicians who make their livings cleaning chimneys and making them safe – a chimney-cleaning log set can give you a false sense of security.

No matter how much creosote can be removed by burning special logs, it’s not enough to satisfy the CSIA, which provides stringent industry certifications to technicians who have demonstrated exceptional skill and knowledge in the areas of chimney cleaning, inspection and repair.

One big problem with chimney-cleaning logs is that you can’t know exactly how well they’ve worked. Unless you can see inside your chimney, it’s impossible to know what did or didn’t happen in there after you burn cleaning logs. This means you really don’t know how much creosote may still exist inside the flue.

Another drawback is that as the burning logs dislodge creosote, the flammable substance can fall down into a roaring fire, which is like throwing lighter fluid on the flames.

If pieces of creosote don’t hit the flames, they may start stacking up on the smoke shelf just above the firebox. In this case, you still have a large amount of creosote in your chimney, only in a different place.

Trust professional chimney sweeps to clean your chimney

Chimney Inspection in Concord, NHThis article isn’t to knock makers of chimney-cleaning logs or cause them to lose business. What this article is about is safety, and ask anybody in the hearth industry, and they’ll tell you there is no substitute for hiring a professional, certified chimney sweep to clean your chimney.

Chimney sweeps not only have extensive training, but they also have specialized equipment that includes hand and power brushes, vacuums, cleaning solvents, scrapers and video devices that allow them to do many things no log set ever could.

I wanted to give 5 stars but they are very busy which meant I had a good wait for both the inspection/cleaning, then for a quote on repairs and then for the repairs. Their prices seemed a little high to me but I have nothing to compare with as they were highly recommended by someone I trust and other companies had plenty of negatives reviews which kept me from getting additional quotes. I am happy with the work and they promptly returned to fix a mistake that had been made. Chris the inspector, Jennifer in the office, and Alex and his repair crew were all pleasant and took the time to answer all of my questions. Alex and his crew even took their shoes off (it was winter) before entering my house without even being asked! So if you are not in a rush and want to ensure you chimney is as safe as possible then I think you'll be happy with Black Moose.

After a recent sweep of our chimney, it was discovered that our flue tiles were cracked. Black Moose techs were hard working, detail oriented and professional! Nice jobs guys! See you next year for my cleaning!

Excellent I highly recommend Black Moose Chimney and Stove; Kelly and Liam are awesome, they did a great job. Extremely professional, arrived early, went through everything with a fine tooth comb ensuring pellet stove was thoroughly cleaned. They also were respectful of my home, conscientious and cleaned up after themselves. Made sure stove worked prior to leaving and told me to call promptly if anything came up afterward. Will definitely use them again.

We've had Black Moose clean our chimney for a number of years.But recently, we had an emergency situation at our home involving our chimney & oil furnace flue, which was caked full of soot from a malfunctioning furnace. They came & cleaned out both flues in no time, even going up on the roof with snow on it! They cleaned up after their work in the interior rooms where the oil furnace and the woodstove are located. Great work. Reasonable prices. Very nice people. You can't go wrong with Black Moose.

Goods: The technicians know their business, very efficient in cleaning/inspection along with cleaning up after the 'dirty work'.Others: Communications could be more effective. Despite early coordination about scope of work (multiple flues within same chimney) the estimate provided did not reflect this and the final invoice was significantly more than the estimate provided.Quote for follow-on chimney relining was significantly more than that offered by other companies in the area (and far more than neighbors experienced for similar work accomplished by other companies)
