Residential & commercial mold air testing — done by the book.
Our certified and experienced technicians at HBH - Healthy Buildings & Homes help homeowners and businesses across Long Island and NYC safely identify airborne mold using best-in-class protocols. Mold spores are a normal component of household and workplace dust, but abnormally elevated levels are a health hazard and a clear sign that an active source exists somewhere in the building.
If you're experiencing unexplained allergy-like symptoms, persistent musty odors, or you've had recent water intrusion, mold air testing gives you objective data — not a guess.
- Calibrated, pump-driven spore-trap sampling
- Indoor samples compared to outdoor controls
- Accredited environmental microbiology lab
- Same-day appointments often available
- Reports interpreted by a CIE
- Residential, commercial, and pre-purchase testing
What's included
What our mold air testing covers.
We follow established indoor environmental sampling protocols so the data we deliver is defensible — for insurance claims, real-estate transactions, or your own peace of mind.
Outdoor Baseline Sample
Ambient outdoor air is sampled first as a control — without it, indoor results can't be properly interpreted.
Per-Room Indoor Sampling
Targeted samples in suspect rooms (basements, baths, HVAC supply, sleeping areas).
Calibrated Pump-Driven Cassettes
Volumetric spore-trap cassettes draw a precise air volume — no passive guessing.
Accredited Lab Analysis
Samples processed by an AIHA-accredited microbiology lab with full genus identification.
CIE-Authored Report
Your results are interpreted by a Certified Indoor Environmentalist, not just printed lab data.
Clear Next Steps
If anything is elevated, we recommend an inspection or remediation plan — no upsell pressure.
Our Process
A clear, certified workflow — start to finish.

FAQ
Frequently asked questions
Questions we hear most often. Don't see yours? Reach out and we'll answer.
How does mold air testing work?+
A calibrated pump draws a known volume of air through a spore-trap cassette over a fixed time. The cassette is sealed and sent to an accredited lab where spores are counted and identified under a microscope.
Why do I need an outdoor sample?+
Outdoor mold spores are normal and ever-present. The only way to know whether your indoor levels are abnormal is to compare them against an outdoor control taken at the same time.
How many samples do I need?+
Typically one outdoor baseline plus one per suspect area. Most single-family homes need 2–4 indoor samples; larger or symptom-driven assessments may need more.
What do the results actually tell me?+
Genus identification (Aspergillus, Penicillium, Stachybotrys, etc.), spore counts per cubic meter, and a comparison against outdoor and reference levels — interpreted by a CIE so you know exactly what action, if any, is warranted.
How fast can I get results?+
Lab turnaround is typically 3–5 business days. Same-day rush analysis is available for an additional lab fee when timing is critical.
Is mold air testing enough on its own?+
Air testing is excellent for screening but doesn't replace a visual inspection when an active leak, visible growth, or specific structural concern exists. We'll tell you which approach fits your situation.
