What is black mold?

Black Mold Removal

Black mold, also known as ‘toxic black mold’ or Stachybotrys chartarum is a type of fungus that can produce toxins and cause a wide range of immune system reactions and health problems in humans. It typically grows on household materials that have been exposed to moisture and contain organic matter, such as drywall, carpet, insulation, or sub-flooring. The leading causes of black mold causing moisture are water damage, water leaks, condensation, water infiltration, or flooding. Essentially, black mold must have a constant supply of moisture to grow, so an undetected leak in your home is its favorite food supply.

Just because black-colored mold is found in your home, does not mean it’s the notorious black mold. The word “black” is a little misleading. This variety of toxic mold does not necessarily need to be black in color, it can range in color from greenish-black to gray, to brown.

How to Identify Black Mold

Stachybotrys, or black mold, is dark in color and typically has a musty, earthy scent. This type of mold typically grows in rings and can sometimes have flecks of orange or white interspersed throughout the affected area. Most of the time, black mold has a slightly furry appearance. If the mold growing in your home checks these boxes, call a professional. The only true way to know if the mold growing in your property is Stachybotrys is to get it tested by a professional.

You can get your home tested for mold through an environmental testing company. Mold testing typically involves a technician coming to your home and taking air and surface samples, which are then analyzed in a lab to determine if mold spore levels indicate a risk. Then, you’ll be given recommendations on what is to be done, and a restoration company can be brought in if necessary.

Where does black mold appear?

Areas susceptible to moisture are usually towards the lower portions of the home, such as basements or crawl spaces that may have small leaks from water sources. Black mold may also occur in bathrooms that are not well-ventilated or in laundry rooms if a leak occurs.

An unexpected place where black mold often appears is in HVAC systems. Air conditioning units and vents are often dark and have plenty of dust, which provides the organic matter that mold needs to thrive. Add in moisture, and you’ve got the perfect conditions for mold. Mold in HVAC systems is often overlooked because it typically grows on internal components. However, these are among the most dangerous places for mold to grow, as air traveling through the vents can help distribute mold spores and hasten allergic reactions.

What are the health risks of black mold?

Black mold can cause many serious health hazards. There are numerous negative health effects from mold exposure, such as mental impairment, breathing problems, internal organ damage, and in a few serious cases, even death.

How can I prevent black mold growth?

identifying mold presence in drywallBlack mold thrives on water damage caused by leaky pipes or appliances. Once leaking water seeps into a porous material like drywall, black mold will take up residence. Water leak detectors can help you catch leaks before mold even enters the picture. Place water leak detectors around toilets, water heaters and boilers, sump pumps, washing machines, and faucets in your home, and you’ll be able to catch most leaks before they become moldy disasters.

If sensors aren’t in your plan for mold risk management, be sure to regularly check your property for leaks, dampness, or existing mold growth. Common problem areas can include closets, bathrooms, or basements. Because mold thrives on moisture, using a dehumidifier in these areas can sap your indoor air of excessive moisture and inhibit mold growth. Keeping humidity below 50% can help prevent black mold and its other moldy cousins from showing up.
