TL;DR
Clearance sampling is the collection of air or surface samples after mold remediation, ideally by a third-party hygienist, to verify the work area is clean before containment comes down. Spore-trap air samples inside the containment are compared with outdoor and unaffected-area baselines, sometimes supplemented by tape lifts or swabs of cleaned surfaces.
What it means
Clearance sampling is the collection of air or surface samples after mold remediation, ideally by a third-party hygienist, to verify the work area is clean before containment comes down. Spore-trap air samples inside the containment are compared with outdoor and unaffected-area baselines, sometimes supplemented by tape lifts or swabs of cleaned surfaces. Paying for it separately from the remediation contractor avoids the conflict of interest of a company grading its own work.
