If no mold has been found upon the visual inspection process and the client and inspector may decide to do in air sampling to determine the amount of mold spores in the air. Two samplings must be taken, one outside the building is a standard, and the other in the infected area.
The Air-O-Cell™ Air Sampling cassette is a sampling device designed for the rapid collection and analysis of a wide range of airborne aerosols. These include fungal spores, pollen, insect parts, skin cell fragments, fibers, and inorganic particulates. Air enters the cassette, the particles become impacted on the sampling substrate, and the air leaves through the exit orifice. The airflow and patented cassette housing is designed in such a way that the particles are distributed and deposited equally on a special glass slide contained in the cassette housing called the “trace.”
Tape test inspection
Some mold may impregnate itself within the fibers of the material, where a swab test would be unpractical, i.e. ceiling tiles, concrete block etc. A tape lift is used for surface sampling by stripping the suspect area surface with specially designed clear tape. The sample is then transferred to a microscope slide and then placed in a seal tight container and transported to a Dr. Mold laboratory for complete analysis.
Swab testing for mold
This type of testing is normally done were visible mold is found to determine the type of fungi. The results of this testing will determine if the mold as present in this area alone toxic or non-toxic. If visible mold is found in more than one location on the property a swab test must be done at each location. Laboratory results will determine the type of microbial growth that is present.
Visual Mold Inspection
The visual inspection will reveal any mold on surfaces and determine if there is any mold problems that may be hidden inside cabinets or under sinks. A moisture meter will detect moisture within the drywall or deeper into the wall. If an area has been determined to be high in moisture content then and high-tech invasive probe can be sent down inside the walls to visually see within the walls. This will determine if there is a existing problem due to a roof, siding, or plumbing leak.
A Dr. Mold certified mold Inspector will come to your property. He will do a complete visual walk-through. He will check for moisture problems, pipe supply lines, drain leaks, and other types of water intrusion that may or may not be obvious. This will include, but is not limited to, the following:
- Inspection of the siding
- Inspection of the attic
- Inspection under sink cabinets
- Inspection of Windows
- inspection of walls
- inspection of carpets
