Mold Testing & Assessment

Mold testing is appropriate in five specific scenarios — outside these, visual inspection alone is often sufficient. (1) Real estate transactions on properties with disclosed water history, basement moisture indicators, or buyer-stated symptom concerns. Pre-purchase mold testing produces lender-acceptable documentation for closing files and protects the buyer against post-closing surprise. (2) Post-water-damage assessment 14-21 days after an intrusion event. Standard air sampling 14+ days post-event verifies whether mold growth has been triggered; this is the diagnostically meaningful window for catching slow-growing species (Stachybotrys, Chaetomium). (3) Habitability or litigation matters where independent evidence with chain-of-custody is required. Court-format reports require AIHA-accredited lab analysis, photo documentation, and methodology that survives cross-examination. (4) Symptom-driven testing where building occupants report respiratory, neurological, or other symptoms that may correlate with environmental exposure. Important: testing identifies environmental conditions; the clinical interpretation belongs to the treating physician. (5) Post-remediation clearance testing after professional mold remediation. NYS Article 32 requires the clearance assessor be different from the remediator; we perform this work for remediation contractor partners. For pre-purchase situations without specific concerns or symptoms, mold testing is buyer-discretionary. Cost-benefit favors testing in pre-1970 housing with basement-heavy construction or in any property where the seller acknowledges water history.
