Indoor mold forms when moisture, building materials, and airflow create the right biological conditions. This section explains how mold grows, how spores move through a home, how mycotoxins form, and which testing methods provide reliable insight into contamination. You’ll also find guidance on identifying mold-like smells, learning where mold hides, and understanding how moisture affects microbial dynamics.

These articles distill scientific principles used in professional mold investigations — including spore trap analysis, culture-based testing, PCR diagnostics, and mycotoxin toxicology. You’ll learn how to recognize early microbial indicators, how to respond to high-spore environments, and how to interpret mold-related symptoms inside a home.

If water contamination may be part of your mold issue, you can quickly screen for bacterial activity using the Detekt Home Mold Test, which identifies microbial intrusion in plumbing systems often mistaken for mold.
