What air sampling reveals
Air sampling is the most reliable way to measure what is circulating in your indoor environment. By drawing a measured volume of air through a collection cassette, we capture mold spores onto a microscope slide that the laboratory analyzes by genus and concentration. Indoor results are compared to an outdoor control to identify abnormal indoor sources.
Equipment matters
Raphael Mold Inspection uses professional, calibrated air pumps and the cassette types preferred by accredited laboratories. Calibration ensures every sample represents the same air volume — a requirement for defensible results that hold up for real estate, insurance, and remediation use.
Where samples are collected
Inspectors typically sample affected rooms, HVAC return air, common living spaces, and an exterior control. For multi-unit buildings, separate samples may be taken per unit. Sampling locations are chosen based on the visual assessment and moisture findings.
From sample to action
Cassettes ship under chain-of-custody to a partner laboratory. Once results arrive, your report explains spore counts in plain language, compares indoor to outdoor, identifies likely sources, and recommends next steps. We do not perform remediation, so recommendations remain impartial.
