Toxic Mold Sampling & Testing
Valley Home Inspection can perform Air tests or take surface samples to help determine if mold is present in a home and if so, what type of mold is present. This service is not part of a standard home inspection but can be added to it.
We use two types of mold testing techniques to collect mold air samples both indoors and outdoors [called outdoor control test].
-
Controlled air testing impactors that use an air pump to draw in and impact airborne mold spores onto the sticky surface of a mold culture plate. These impactors are then sent to a laboratory for analysis.
-
Direct sampling of visually-noticeable mold growth through lift tape sampling which is then sent to a laboratory for analysis.
Is there mold contamination inside the building's heating, ventilating, and air conditioning system [HVAC], and/or HVAC ducts? We can tape mold culture plates [sticky surface facing inward] onto at least one air supply register grill of each zone of your heating, cooling, and ventilating [HVAC system], and then run the HVAC system for 15 minutes to impact possible mold infestation spores onto the sticky surface of the mold culture plates. These plates are then sent to a laboratory for analysis.
