Air Sampling
Air sampling is a more inclusive type of testing that determines the quality of breathable air within your home. We use spore traps as these cassettes are designed for rapid collection of a wide range of airborne aerosols including mold spores, pollen, insect fragments, skin fragments, pet dander, natural fibers, synthetic fibers, non-biological debris, combustion residue, HVAC duct residue.
When doing Air Samples our protocol requires a minimum of one outside control sample to establish a baseline, and one indoor sample. In order to establish a baseline an outdoor control sample close to the exterior is always required.
Then using a series of targeted questions, sophisticated tools, and knowledge gained from experience, our inspectors will determine where the interior air samples should be performed. They will discuss these locations with you before proceeding.
In certain conditions, and if deemed necessary The Mold Guyz can also perform "Cavity" air samples that can confirm if there are hidden mold colonies existing in the cavity space. These samples are considered destructive sampling, as drilling holes into the wall is required to gain access to the wall cavity.
A Chain of Custody is used when sending the samples to a certified independent laboratory for analysis. Their report will show the types of mold, and the amount of mold in the air per cubic meter.
Surface Sampling
If there is visible microbial growth observed in an area of concern we could choose to use this specific type of mold testing. Using a wet sterilized swab or bio-tape to lift a sample of visible growth from the surface. The independent AIHA certified laboratory results will include the name of the mold spores identified on the sample.
In some cases we will use swab / tape lift sample in conjunction with air samples to confirm or deny that the visible mold is affecting the air quality with the area.
Bulk Sample
Bulk Sampling is another form of mold testing that can be a useful tool instead of using swab or tape lift samples. In cases where the home owner or building owner allows, we can remove a bulk sample of the growth on the building materials. These can be in as small size as 3"x 3" or as large 5"x 5". For Example, a piece of drywall, carpet, curtain, baseboard.
