Mold Testing

An ASI accredited mold inspector’s primary mission is to protect the health and well being of both their clients and the general public from microbiological and other environmental hazards in homes, condos, apartments, and other occupied buildings.

ASI performs mold inspections in compliance with the standards of practice set forth by the Mold Inspection Protocol Training Institute.

Because we function as an independent inspection firm and not as a remediation firm, we have no conflict of interest. Protecting your interest and your health is our only concern.

Mold exposure affects certain individuals more severely and quickly than others including:

  • Infants and Children
  • Elderly People
  • Pregnant Women
  • Individuals with Respiratory Conditions or Allergies and Asthma
  • Persons with Weakened Immune Systems (e.g., People with HIV Infection, Chemotherapy Patients, or Organ or Bone Marrow Transplant Recipients, and Autoimmune Diseases)

About Mold Inspections


One very important step in properly diagnosing a potential mold problem is to inquire of any current, existing problem conditions, such as but not limited to the following: moldy odors, humidity problems, condensation problems, any known past or present roof leaks, plumbing leaks or past floods and any visible mold observed.

It is common to find mold growth in and around air conditioners and AC ductwork, under kitchen and bathroom sinks, behind toilets, on shower stall walls, on garage interior walls, under and behind aquarium stands, on drywall material, carpets, and ceiling acoustical tile as well as many other areas in need of inspection.

Digital photographs may also be taken to document your particular conditions.


Often, evidence of mold cannot be visually seen but must be detected instead by taking samples of microscopic mold spores for analysis. Typically, air samples are taken of the outdoor and indoor air by using Air-O-Cell for spore collecting.

This is done to determine if mold spore counts filtered from the indoor air are unusually high in comparison to the mold spore count filtered from the air just outside your property. It also indicates types of mold at the property. The dominating presence of one or two kinds of fungi indoors and the absence of the same kind outdoors may indicate a moisture problem and degraded air quality

The Air-O-Cell is a typical and basic test that is often done as part of a professional mold inspection routine. Depending on visible conditions, other types of mold sampling may be required, and including surface sampling with the aid of swabs and/or simple, clear tape.

Lab Testing and Reporting

It is crucial that an accredited professional microbiology lab be used for analysis of any mold or mold spore samples obtained at the property. The lab report often gives information on the number of spores per cubic meter of air and the specific types of molds found, including their potential health effects. The printed lab results specifying what types of mold were found will be provided to you.

Interpreting Sampling Results

A useful method for interpreting microbiological results is to compare the kinds and levels of organisms detected in different environments. Specifically, in structures without mold problems, the qualitative diversity of airborne fungi indoors and outdoors should be similar. Conversely, the dominating presence of one or two kinds of fungi indoors and the absence of the same kind outdoors may indicate a moisture problem and degraded air quality. Also, the consistent presence of fungi such as Stachybotrys chartarum, Aspergillus versicolor, or various Penicillium species over and beyond background concentrations may indicate the occurrence of a moisture problem that should be addressed and a potential atypical exposure. Generally indoor mold types should be similar and levels should be no greater than outdoor and non-complaint areas. Analytical results from bulk material or dust samples may also be compared to results of similar samples collected from reasonable comparison areas.

Dear Mr. Thornton, I appreciate the time and attention you gave to the department last September at Fire Station 9. The moisture and mold investigation you performed was very professional and your consultation concerning the test was most appreciative. Your detailed report helped us to determine the needed repairs. Thank you very much.

Doug, You performed a home inspection on our new house in Elmore a few weeks ago. During the inspection you noticed that there were no signs of flashing near the dormer. Turns out that there wasn't any flashing! The builder has taken care of it, but said that a previous home inspection took place about 6 months ago and the inspector (or anyone else for matter) didn’t notice that flashing was missing. I don't know how much testimonials would help you, but I am happy to provide mine. I appreciate you doing such a thorough job.
