3 Hidden Dangers That May Be in Your Chimney

Heating systems and chimneys are one of the main sources of home fires in the U.S. Keeping a chimney clean and well-maintained is one of the most important things you can do for your home safety and for your health. Still not convinced? Check out a few of the hidden dangers commonly found in chimneys and fireplaces, and learn why it’s so important to have your chimney inspected and cleaned each and every year.


One of the main threats homeowners who use their chimneys have to deal with is creosote. Creosote is a dark, tarlike substance that builds up in the chimney over time as a result of combustion byproducts collecting in the flue, such as smoke, water vapor, and other gases. This substance is highly flammable, and it is likely present to some extent even if you didn’t use your chimney that often last year, which is why you want to have your chimney cleaned out each year.

Structural Damages to the Flue or the Masonry

Another potential danger that could be present in your chimney is any structural damage left over from a past fire or from all of the wear and tear that your chimney takes on through the years. This makes it easier for a future fire to move out of the chimney and spread to other parts of your home. A Level 1 chimney inspection includes a thorough look at any potential cracks and holes.

Water Damage

One of the best steps you can take to protect your chimney is to waterproof it. Water is actually one of the biggest threats to any chimney, especially in climates with freezing temperatures. Water expands as it freezes, which can cause damage to your masonry, and it can allow creosote to build up faster if it gets in your chimney flue. Having a chimney technician install a chimney cap and use a waterproofing agent on your chimney can help protect against structural damage.
