Does your basement have a musty odor? Have you seen spots of various colors on the different surfaces in your home? Air quality testing can be conducted to determine if the types of mold spores on the exterior of the home match that of the interior of the home. If there is an elevated number of mold spores (of a different type) on the interior of the home, it may be necessary to mitigate. This is a non-viable testing method and all testing materials (air cassettes) are sent to a lab and examined underneath a microscope. If there is apparent visible mold, samples will be gathered on every surface and from every different color of mold using swabs and bio-tape.
