We perform a comprehensive inspection which includes visual & infrared screening and moisture detection to detect hidden moisture, and we collect air and surface samples from suspected mold-affected areas.

We use advanced chemical and particulate sensors to detect formaldehydes, volatile organic compounds, fine particulates (PM2.5), carbon dioxide, and other contaminants that may cause similar symptoms to toxic mold exposure.

Samples are analyzed at an AIHA-accredited lab — species identified, spore counts measured — and every result is reviewed by our on-staff microbiologist.

We send you a comprehensive interactive web report containing plain-English findings, microbiologist-verified testing results, recommendations for mold remediation and improved air quality, along with preventive tips to avoid future issues.
