Mold Air Quality Testing · California
How do you test for 'black mold' in California?
Short answer
Testing for 'black mold' (Stachybotrys) involves air sampling and surface swabbing. Because these spores are heavy and sticky, they aren't always found in the air, making professional surface sampling essential for detection.
While the term 'black mold' is often used to describe Stachybotrys chartarum, many types of mold appear black. Some are relatively harmless, while others are known to produce mycotoxins. ClearPoint Environmental identifies the specific genus of mold present. If we find Stachybotrys, it is a clear indicator of long-term water damage that requires immediate attention.
