Water in your chimney allows mold to thrive. This is not a good thing. Make sure to waterproof your chimney.

As chimney professionals, a lot of what Chief Chimney Services technicians will talk to homeowners about regularly focuses on preventing fire hazards, maintaining proper draft and keeping up with regular maintenance. It’s also important for us to talk about something that might seem a little less obvious with your chimney system: mold growth.

Mold can and will grow and spread just about anywhere it gets access to moisture and food (like the building materials that make up your home). So if moisture makes its way into your chimney — through damaged masonry or other damaged components — that dark, enclosed and moist space can make a perfect home for mold. Since our chimneys are largely dormant for months out of the year, and Long Island humidity contributes a healthy share of moisture just about year-round, we need to be particularly aware of chimney mold here.

Why Do I Need To Know About Chimney Mold?

Mold growth creates stains and smells, and those annoyances are reason enough to not want it in your home. But related health issues are more concerning. Airborne mold spores have been shown to contribute to a variety of health issues, including respiratory problems, skin and eye irritation and longer-term illnesses. Certain types of mold — so-called “black mold” — are toxic, and have been linked to severe issues from pulmonary illnesses to nerve damage and more. People who already struggle with asthma and other respiratory illnesses or have weakened immune systems have been found to be particularly susceptible to the effects of mold. So it’s important to know about mold growth, and to deal with it quickly if it’s found in your home.

How Do I Know If There’s Mold In My Chimney?

It’s possible that you’ll see the signs of mold on or around your chimney — like discoloration of the masonry or adjacent building materials, or flaky and crystallized white efflorescence, which isn’t mold, but does point to a moisture intrusion problem. More often, though, if mold is growing inside your chimney where it isn’t in plain sight, the first indication will be a musty odor. We all know the smell of mold — it’s what most of us think of as that dank and unpleasant old-basement smell. If you notice an odor, Chief Chimney Services can inspect the chimney to assess whether there’s a moisture issue and mold growth.

How Does Mold End Up In My Chimney?

Mold spores are everywhere, and if they get a dark space to thrive and moisture to feed on, they’ll grow. So mold growth in your chimney is a sure indication that there’s a moisture issue — and dealing with that moisture issue is the key to dealing with your mold.

What Can I Do To Get Rid Of Mold In My Chimney?

The most effective way to get rid of chimney mold: Call Chief Chimney Services. Since breathing mold spores can be dangerous, it’s generally not advised to clean mold yourself on a space that’s any larger than 10 square feet (about a 3 by 3 square). If there’s mold growth inside your chimney, it’ll require special tools to properly get to it, as well. But beyond that, cleaning mold without addressing the moisture intrusion or leak issues is a temporary fix — the mold will grow back again. We can inspect and clean your chimney, find any leaks or moisture intrusion issues (which can be anything from degraded masonry to a cracked chimney crown  or damaged flashing) and provide solutions and repairs.

If you have any questions or concerns about chimney mold, we’re always here to help. Just give Chief Chimney Services a call!
