Defining Mold: This mold is a slow growing fungus - Stachybotrys, Aspergillus, penicillium
Mold Inspection Information: Defining Mold

The presence of mold, water damage, or musty odors should be addressed immediately. In all instances, any source(s) of water must be stopped and the extent of water damage determined. Water damaged materials should be dried and repaired. Sampling is then recommended to determine the type and extent of the existing mold. Mold is a structural, health and environmental problem. Some mold defects can't be seen and will only be detected through sampling.


This mold is a slow growing fungus. It grows well on high cellulose materials like straw, grass, saw dust, lumber and drywall plaster board or ceiling tiles. Like a fungi, it requires a moisture source. About 15 species of Stachybotrys can be found worldwide, but it is most common in the Western U. S. Generally, this mold grows where the relative humidity is above 55 percent or the material is water-saturated. In studies conducted in North America, Stachybotrys was found in 2 to 3 percent of home environments sampled. (more about Stachybotrys mold)


A group of molds which is found everywhere world-wide, especially in the autumn and winter in the Northern hemisphere. Only a few of these molds can cause illness in humans and animals. Most people are naturally immune and do not develop disease caused by Aspergillus. However, when disease does occur, it takes several forms.

Some Penicillium species are fairly common indoor fungi, even in clean environments. This particular specie of fungi can proliferate in abundance in indoor environments. P. species can be found at the sub-basement levels offices and rooms, in libraries, auditorium, storage room of paper materials and also in ventilation systems. Some P. species can produce small, nondescript conidia and complex mixtures of metabolites that are more or less toxic. (more about Penicillium mold)
