Moisture is the number one fundamental threat to chimneys. Chimney mold is among the problems caused by moisture intrusion. Water makes its way into chimney systems as a result of deterioration. Whether the mortar, chimney crown, or masonry is damaged, these components and others will accommodate moisture intrusion unless they are repaired in a timely manner. The flashing can pull away, or the chimney cap could suffer disrepair in a storm. 

Mold thrives anywhere it is moist and dark. The inside of a leaky chimney is a great breeding ground for mold. 

Is Chimney Mold a Threat to Health?

Besides being unsightly in appearance, mold can cause problems far worse than creating a musty smell. Health problems caused by mold can be as mild as itchy eyes, sneezing, and skin irritation. Spores released into the air by mold can also aggravate allergies and cause asthma attacks. Even worse effects of mold are possible, including those associated with mold poisoning. Symptoms include:

  • Chronic fatigue
  • Dizziness
  • Difficulty breathing
  • Chronic coughing or sneezing
  • Persistent headaches
  • Nausea
  • Asthma attacks

What are Signs of Mold Growth?

If you see mold on the outside of your chimney, it may be an indication that it is growing inside your chimney, as well. Chimney mold appears as black or green spots. An earthy, musty smell coming from your fireplace is another good indication that you have chimney mold. 

How Do You Get Rid of Chimney Mold?

Because it is a toxic substance, be sure to contact your trusted chimney sweep company for the removal of chimney mold. You can find do-it-yourself solutions for removing chimney mold, but there would likely be no way to access mold growth deep within the chimney flue. Professional chimney sweeps have the training, experience, and tools to effectively and safely remove chimney mold.

Is There a Way to Prevent Chimney Mold?

A good question to ask is whether chimney mold is a problem that can be avoided in the first place. Simply using your fireplace regularly during cold weather helps by circulating air and preventing the accumulation of moisture. Scheduling annual chimney inspections and cleaning is recommended by the National Fire Protection Association (NFPA). The Chimney Safety Institute of America (CSIA) also recommends annual chimney inspections, but they suggest having your chimney cleaned when the buildup of creosote is 1/8” thick.

There’s another vital thing you need to know about chimney mold. It is essential to get a chimney cap installed if you don’t already have one. The chimney cap is a first line of defense against moisture getting into the chimney and creating problems such as mold growth.

After your chimney has been inspected and has been found with no signs of water intrusion, schedule waterproofing of the chimney. Contact chimney sweeps for this service because it is important that the correct sealant be used. Also, proper application makes all the difference.
