Mold is not a single thing. We use the words like mildew and others to describe common house hold growths such as those seen on food that has gone bad. In fact mold is many different types of fungi. Approximately 1,000 different types of mold in North America alone. When testing the types of mold are narrowed down to a group that are most concerning. Molds that are present when there is water damage or molds that are known allergens.

 

When and When Not to Sample

Samples are generally best taken if visual, non-invasive examination reveals apparent mold growth or conditions that could lead to growth, such as moisture intrusion or water damage.  Musty odors can also be a sign of mold growth.  If no sign of mold or potential for mold is apparent, one or two indoor air samples can still be taken, at the discretion of the inspector and client, in the most lived-in room of the house and at the HVAC unit.  

Outdoor air samples are also typically taken as a control for comparison to indoor samples.
