Volatile Organic Compounds (VOCs) are carbon-containing chemicals that evaporate at room temperature, releasing gases into the air we breathe. They are found in paints, adhesives, solvents, flooring, cleaning products, and furnishings, and can accumulate to problematic levels in poorly ventilated or recently renovated spaces. Formaldehyde (HCHO) is among the most common and consequential indoor VOCs, particularly in homes with newer composite wood products or laminate flooring, and is significant enough that it is typically assessed separately using its own dedicated sampling methodology.

Exposure to elevated VOC levels has been associated with headaches, dizziness, eye and throat irritation, and fatigue in the short term, with certain compounds — including benzene and formaldehyde — carrying more serious long-term health concerns at sustained elevated concentrations. These adverse health experiences can mimic negative health reactions associated with mold, which is why we perform a complementary initial scan for VOCs using handheld devices whenever we perform a mold inspection.
