Mold and Moisture

NV5 offers mold and microbial consulting services, including survey, evaluation, abatement design and post-remediation inspection. Per the recommendations of AIHA and several State agencies, NV5 does not offer mold remediation services, in order to avoid potential conflict of interest.

Recent publications by the World Health Organization (WHO) and the National Academy of Sciences (NAS), in conjunction with the US Centers for Disease Control and Prevention (CDC) have concluded that molds are proven to cause allergic response in sensitive individuals. Associated symptoms are primarily limited to allergic response, such as nasal congestion, eye irritation, hay fever, and exacerbation of asthma. Other reported symptoms such as memory loss, infection and cancer have not been proven to be associated with mold exposure in the indoor environment.

With the above in mind, NV5 takes a realistic approach to microbial evaluation and control. Mold should be dealt with, when found. However; reports from some media organizations and uninformed self-proclaimed consultants regarding the need for evacuation in the presence of mold growth is largely unfounded.

Additionally, the use of biocides, ozone and microbial inhibitors is generally not helpful or recommended.

When performing evaluations for mold in the field, NV5 uses only certified personnel, including Certified Indoor Environmentalist (CIE), Certified Indoor Air Quality Consultant (CIAQC), and Certified Industrial Hygienist (CIH). All reports and evaluations prepared by AQC are reviewed and signed by a CIH with more than 15 years experience in dealing with indoor air contaminants.

NV5’s field experience has led us to the conclusion that simply performing air sampling alone is entirely insufficient and prone to yield misleading conclusions. This information has recently been confirmed by such prestigious organizations as AIHA, ACGIH, EPA, OSHA, WHO and ANSI. As such, NV5 combines proven technology and scientific protocols into every survey we do, by performing moisture measurement, visual identification, HVAC inspection, and/or borescope evaluation of wall cavity interiors, along with bioaerosol sampling. Each survey or surveyed facility is different, and any or all of the previously listed scientific evaluation protocols may be used in an effort to provide the most accurate evaluation possible, while minimizing costs to our clients, wherever possible.
