We perform comprehensive odor identification inspections for indoor malodors and suspected VOCs (Volatile Organic Compounds) concerns to help determine the potential source and origin of the issue. Our investigations evaluate building conditions, potential contaminant pathways, HVAC influences, moisture-related conditions, occupant observations, and other contributing factors affecting indoor air quality.

​

In indoor environments, odors can originate from numerous sources and may indicate the presence of elevated VOCs, moisture intrusion, microbial growth, combustion byproducts, sewer gases, or other environmental contaminants.

Common indoor odor categories include:

​

• Chemical or solvent-like odors – often associated with VOCs from paints, adhesives, flooring, furnishings, or cleaning products.

• Musty or earthy odors – commonly related to moisture intrusion, mold growth, or damp building materials.

• Burning or smoky odors – may originate from tobacco smoke, electrical issues, fireplaces, or combustion appliances.

• Sewer or sulfur-like odors – frequently linked to plumbing defects, dry traps, or sewer gas intrusion.

• Sweet or fragrance-type odors – may be emitted from air fresheners, fragrances, cleaning products, or certain chemical compounds.

• Pet, biological, or organic decomposition odors – can stem from animal contamination, bacteria, or decaying materials.

​

Some VOCs, including formaldehyde, benzene, and compounds associated with tobacco smoke, are classified as carcinogens and may pose serious health concerns depending on the type, concentration, duration of exposure, and individual sensitivity. Elevated VOC concentrations are often more problematic during and after new construction, remodeling, or installation of new furnishings and finishes, where off-gassing from building materials can persist for extended periods.

​

When appropriate, we can also conduct EPA Method TO-15 VOC testing in conjunction with the inspection. This specialized testing method uses calibrated sampling equipment and evacuated stainless-steel canisters to collect whole-air samples for laboratory analysis. EPA Method TO-15 is capable of identifying and quantifying up to 97 volatile organic compounds (VOCs) from the 189 hazardous air pollutants listed under the Clean Air Act.​ The analytical results can help identify specific VOCs and their concentrations, which may then be interpreted and compared to applicable occupational and health-based exposure guidelines such as those established by OSHA (Occupational Safety and Health Administration) and NIOSH (National Institute for Occupational Safety and Health).

By combining detailed odor investigations with advanced VOC testing, we can help identify potential contaminant sources and provide practical recommendations for improving indoor air quality and resolving odor-related concerns.
