Mold (fungi) is present everywhere, both indoors and outdoors. More than 100,000 species of mold
are currently known, of which approximately 1,000 species are common in the United States. The
most common species encountered include species of Cladosporium, Penicillium, and Aspergillus.
Mold is most likely to grow where there is water or dampness, as in bathrooms and kitchens
,wherever there is plumbing, the underside of carpets and pads, the surface of walls behind furniture
(where condensation forms) ceilings and attics, back side of drywall, wallpaper and paneling, inside
HVAC systems and duct work, clothing and food.
The first step in a mold assessment is to determine the possible cause(s) of the problem and the
location within the building of concern by conducting interviews with tenants that have complained
of health issues and suspect odors. The next step consists of the LandScience representative
conducting a visual inspection to look for evidence of mold and to identify areas that are conducive
to mold growth. Often, the LandScience representative utilizes an infra red camera to identify water
leaks behind walls, ceilings, floors, and other building materials. In addition, the LandScience
representative utilizes a moisture meter to collect moisture measurements on wall and ceiling
surfaces. If areas of concern are identified during the visual inspection, then the LandScience
representative utilizes the latest sampling and analytical equipment to collect air and surface samples
for the analysis of mold and mold spores.
