Mold comes up in almost every Long Island real estate transaction — as a fear, a finding, or a negotiation point. Here’s how to approach it with accurate information instead of alarm.
When Is Mold Testing Recommended
Visual evidence of moisture damage, musty odors in the basement or attic, known flooding history, or HVAC systems that have experienced water intrusion — these are legitimate triggers for air quality or surface mold testing. Mold testing without a specific concern is a low-yield exercise; testing with a real trigger gives you actionable information.
Air Quality vs. Surface Testing
Air quality sampling measures airborne spore counts in affected areas versus a control sample from outdoors. Surface swabs or tape lifts identify the species on a visible growth. Both have their place. Air sampling is useful when you can smell something but can’t find the source; surface testing confirms what you’re looking at and whether remediation is necessary.
What to Do With Positive Results
Not every mold finding means the deal is dead. Localized mold from a single moisture event — a past roof leak, a failed window seal — is remediable. Widespread mold from chronic water intrusion or HVAC contamination is a different category. Your inspector can help you understand the scope, and a certified industrial hygienist (CIH) can provide a remediation protocol if needed.
The Inspection Boys offer mold testing as part of or separate from a standard home inspection. Book at homeinspectionsli.com.
