VOC Home Survey Testing

The Green Valley Group provides VOC Home Surveys to test for air quality. Home air quality is a growing health issue throughout the US. Homeowners and potential home buyers are concerned about what airborne contaminants could be present in their homes. VOC testing is an effective tool used to monitor a home for chemicals in the air (VOCs) and actively growing mold (not the presence of mold spores).

What is a VOC Home Survey Test?

A VOC Home Survey is an advanced analysis method used by home inspectors, industrial hygienists, and indoor air quality/environmental consultants to check for hidden mold and airborne chemicals in home air. With a single air sample, IAQ Home Survey reports the total levels of Volatile Organic Compounds (VOCs) and Mold VOCs (MVOCs), produced by actively growing mold. In addition, possible sources of VOC contaminants in the home can be predicted. Information gleaned from these reports can then be used to assess the home’s air quality, and the home occupants can begin to take steps to reduce or remove the offending sources from their home.

How is the survey performed?

The VOC Home Survey test is performed by a home inspector, HVAC contractor, industrial hygienist, or other home service professional by collecting an air sample with a small sampling kit. Once the air sample is collected, it is returned to the laboratory for an advanced, sensitive analysis that determines the total levels of VOCs (chemicals in the air) and active growing mold present in the home. The test is so sensitive that it will even detect mold growing behind walls or in carpeting, and thus not visible. VOC Home Survey Tests do not detect mold spores — only the presence of mold when active growth is occurring.
