Which type of mold is frequently found in water-damaged buildings?

Stachybotrys chartarum, commonly known as black mold, is often associated with water-damaged buildings due to its preference for moisture-rich environments. This type of mold thrives on materials such as wood, paper, and other organic substances that have been exposed to water, making it particularly prevalent in homes and structures that have experienced leaks, flooding, or high humidity.

When conditions are right—especially in areas with a history of water damage—Stachybotrys can proliferate quickly and can potentially produce mycotoxins, which are harmful to human health. This is why its presence in water-damaged buildings is a significant concern for mold assessors and remediation professionals.

In contrast, while Aspergillus niger, Penicillium chrysogenum, and Cladosporium sphaerospermum can also be found in damp environments, they are not as specifically associated with severe water damage as Stachybotrys chartarum is. Their growth may not necessarily indicate the same level of water intrusion or resultant health risk, making Stachybotrys the most notable in this context.
