Chimney fires cause over 14,000 fires every year in the U.S. and nearly $35 million in property damage, according to the National Fire Protection Association.  What’s even more startling is that most of these chimney fires burn and extinguish themselves and initially are unnoticed by homeowners.  Damage produced by an undetected chimney fire is only discovered later when the homeowner has a chimney sweep company come to their home and provide a chimney sweep and inspection service.  The NFPA recommends that chimneys be swept every year.  It is important to hire a professional company that knows how to sweep a chimney. Homes in Silver Spring, MD need chimney sweeps in the same manner that every other home requires.  

Here are some reasons why homes need a chimney sweep every year

1. Creosote buildup in the chimney

Creosote buildup is responsible for the majority of chimney fires. Smoke emitted by burning fossil fuel or wood rises into your chimney where it cools and produces volatiles, carbon, and water condensation. Unless removed, this condensation quickly converts into an oily, black residue chimney sweeps call creosote.

Creosote develops in three stages: 1) crunchy or porous soot; 2) a sticky, tar-like substance; 3) a hard glaze that is real creosote. Be aware that creosote remains highly combustible in any stage and can almost instantly produce a dangerous, volcanic-like chimney fire.

Conditions that promote creosote buildup include:

  • Flues too large for unlined inserts (wood-burning appliance)
  • Restricted or reduced air supply
  • Burning rain-saturated or unseasoned wood
  • A surface flue temperature that is cooler than normal

2. Animals nest can clog the chimney flue

Even if you only use your chimney occasionally, Birds, bats, squirrels and raccoons may clog the flue their nests. In fact, chimneys with the least amount of use of the most common targets of animals seeking a place to build nests.

3. Chemicals alone won’t do the job

The Chimney Safety Institute of America (CSIA) does not recommend relying on chemicals to clean your chimney. Commercial chimney cleaning products claim to remove creosote from chimneys via fire-supported catalytic action. However, the CSIA states that these chemicals should not be used to replace a thorough cleaning and inspection performed by a professional chimney sweeper.

4. Unseen mortar and/or flue tiles problems

Broken or cracked flue tiles, deteriorated mortar and missing bricks may be inconspicuous to homeowners. Chimney sweepers are trained to detect the smallest hairline cracks and other minor damage that, when exposed to fiery heat, could cause a fast-moving fire.

5. Industry standards require an annual chimney sweep

The National Fire Protection Association’s standard recommends that chimneys be inspected every year.  This requirement is detailed in NFPA standard 211.

Tips for Preventing Chimney Fires

Only burn seasoned wood. The ideal moisture content of seasoned wood should be between 15%-20%. The best way to find out the moisture content is by using a moisture meter.

Use only dry kindling or clean newspaper when starting a fire. Never use kerosene, gasoline, wrapping paper, cardboard boxes and especially, your Christmas tree!

Finally, the Chimney Safety Institute of America strongly urges homeowners to have their fireplaces, vents and chimneys inspected at least one a year by an experienced chimney sweeper for “correct clearances, freedom from deposits and soundness“.

    My and I moved into a home that has fire place right at the start of November and we have loved using it! But, like the article mentions, spring is in the air and that time to do some serious cleaning has come. We have never owned a fireplace before though, so we aren’t sure how to go about cleaning it. After reading this, I see that the best and safest option is to have a service come and and do it the right way.

    Thanks for the post. I think when your dealing with fire it makes sense to hire a professional who knows what they are doing. I like that they inspect the chimney for any issues that could cause serious problems. I didn’t realize that chimneys should be inspected yearly. I can’t remember the last time I had mine inspected.
