Types of Mold To Look Out for After Water Damage

4 min read

If you have recently experienced water damage due to a roof leak, leaky pipe, fire extinguisher, or an unexpected event, their could be a risk and possibility for mold growth in your home.

However, it’s worth noting that there are different types of mold out there. They come in various colors ranging from the typical white, brown, and black to hues of yellow, orange, green, and pink. Additionally, the rate at which they spread and how they affect your property also differ depending on the type.

While a professional mold removal company should be able to address whatever contamination you may have in your home, there’s no harm in educating yourself. To help you get started, here are some of the most common types of mold in homes after water damage.

1. Stachybotrys chartarumCommonly known as “black mold” or “toxic mold,” this type of mold can grow in any room in a water-damaged house. It appears pitch black and is typically slimy to the touch.Unfortunately, mold can spread quickly once it lands on a damp spot in your basement, attic, bathroom, kitchen, or any other area. What’s worse is that the Stachybotrys chartarum is also known to produce toxins that can cause a range of health problems, from allergic reactions to severe respiratory problems.
2. CladosporiumThis variety of mold thrives in both warm and cold temperatures and is often found in the following areas after a water damage event:
   • Basement
   • Attic
   • On sinks, bathtubs, and around faucets
   • On damp curtains and furniture
   Starting as little black dots scattered over the contaminated area, the Cladosporium typically forms large green patches as it grows. When left unchecked, prolonged exposure to this type of mold can not only irritate the skin and respiratory system but also cause serious health issues.
3. AspergillusAspergillus is another common type of mold in homes affected by water. It often appears as powder-like white or black spots, but it also has yellow specks that make it easy to distinguish.Not all molds in this variety are harmful; some people can inhale their spores without experiencing any symptoms. However, people with asthma or existing respiratory conditions may have itchy eyes, runny nose, and rashes after exposure. Ingesting aspergillus can also cause severe allergic reactions and, in the rare cases, an infection called Aspergillosis.
4. AlternariaThis type of mold usually thrives outdoors, but it can easily enter homes through open doors and windows. Once inside, it can quickly grow in damp basements and attics and humid bathrooms and kitchens, appearing in black or green fuzzy spots and giving off a musty smell.If inhaled, Alternaria can cause serious symptoms such as coughing, difficulty breathing, and wheezing.
5. AcremoniumAcremonium is a slow-growing type typically appearing as a white or gray powdery substance. Besides its striking features, this type also gives off a noticeable unpleasant odor.What’s tricky about locating Acremonium is that it often grows inside water-affected drywall and insulation, making it challenging to address early on. Acremonium exposure can unfortunately cause nausea, diarrhea, and vomiting, so prompt mold removal is crucial.
6. ChaetomiumThis is another type of mold that can grow on water-damaged wood, wallpaper, insulation, drywall, and ceiling tiles. Chaetomium often begins as white or gray fuzzy growths until they turn bluish-green as they grow.Like other types of mold, this variety can easily cause severe allergic reactions and respiratory issues in people with weakened immune systems. In rare cases, it has also been associated with liver damage, cancer, and fatal brain infections.
