When visible growth or staining is present, surface sampling -- via swab or tape lift -- collects a sample directly from the suspect area to confirm whether it's actually mold and identify the species, which can help determine remediation approach.

  • Swab or tape-lift sampling of visible growth or stains

  • Species identification to help inform remediation approach

Keep in mind: If there's no visible growth and your concern is general indoor air quality or an odor without a visible source, air quality sampling is the more appropriate starting point.
