Mold Testing (Indoor Air Quality Testing)

Home Inspection Mold Seal

Mold Information

If moisture content is found in a home, and/or a strong musty odor is present, an Indoor air quality test can confirm the presence and type of mold fungi present.

The presence of mold spores can cause irritation  to the the eyes, nose, throat, and lungs. It can trigger asthma attacks and can be particularly troublesome for immune-suppressed persons.

4 of the most common molds found indoors are; Penicillium, Aspergillus, Cladosporium and Alternaria.

The effects of a particular mold species on the occupants of a home should be evaluated and advised by a medical professional.

Testing Information

Indoor air testing will alert to the presence of mold, when a musty smell is present.

An air pump set at 15 lpm (liters per minute), draws a sampling of air through a collection device, called an air-o-cell cassette. The air-o-cell cassette has a laboratory slide contained within, that captures mold spores. This cassette is analyzed by a laboratory, and the concentration level of mold is included in a report.

 

 

  • A sample is taken outside, nearby an exterior door (preferably a Northern facing door),  as a control sample.

  • A second sample is taken in the center of an interior room where conditions are likely for mold growth.

  • A chain of custody form is completed for each sample (logging serial numbers, temperature, humidity, locations, etc.)

  • The collection media and chain of custody forms are overnighted to InspectorLab in Florida, who will in turn, send out a report on the presence and concentrations of mold, the same day.
