Sussex Environmental Consultants (SEC) provides specialized odor evaluations to identify and diagnose chemical, environmental, or building-related odor concerns. Unexplained odors can originate from a wide range of sources—including off-gassing building materials, ventilation contamination, chemical spills, sewer gases, microbial activity, or outdoor infiltration. Our team uses a combination of real-time monitoring and laboratory-based analysis to determine the source and severity of the issue.

SEC utilizes advanced instruments such as VOC meters, photoionization detectors, and humidity/temperature profiling to assess indoor conditions and narrow down potential causes. When a more detailed analysis is required, we offer EPA Method TO-15 summa canister sampling, which captures indoor air for laboratory identification of hundreds of volatile organic compounds at extremely low concentrations. These results help confirm or rule out specific chemical contributors responsible for nuisance odors.

All findings are interpreted by certified environmental professionals, and a clear, comprehensive report is provided outlining likely odor sources, contributing building conditions, and recommended mitigation or corrective actions. Whether odors are intermittent, persistent, chemical-like, musty, or unexplained, SEC’s odor evaluation services provide evidence-based answers and practical solutions to restore a healthy and comfortable indoor environment.
