Overview
Indoor Air Quality Testing: what we actually do.
Indoor Air Quality (IAQ) testing is a broader panel than mold testing — it can include VOCs, formaldehyde, carbon dioxide, particulate matter, and bioaerosols. We focus on the bioaerosol/mold side specifically. For full VOC panels, we partner with industrial hygienist firms.
When to call us
- Asthma or respiratory complaints in a specific home or room
- Post-construction verification after a remodel or new-build
- Sensitivity panel for immunocompromised residents
- Comparative sampling across multiple rooms to find a source
- Baseline sampling before moving into a new home
Our process
01
Consultation
Understand the specific complaint: symptoms, timing, rooms affected. Design a sampling plan that will actually answer the question.
02
Multi-point sampling
Air samples in each room of concern + outdoor control. Same methodology as mold testing, but broader interpretation.
03
Temperature/humidity logging
Data loggers placed for 48–72 hours capture environmental baseline. Elevated humidity in a specific room often reveals the source.
04
Lab + report
Full panel from AIHA lab. Interpretation with remediation recommendations (if warranted) or 'all clear' with data to prove it.
The real causes we see in Long Island homes
Kids with worsening asthma
The #1 reason people call for standalone IAQ testing. Finding the source (hidden leak, HVAC mold, bedroom humidity) is often life-changing for the family.
Post-construction dust and VOCs
After a major remodel, particulate levels stay high for weeks. Worth confirming before an infant or asthmatic resident moves in.
New-home purchase baseline
Before closing on a new build, a baseline IAQ panel protects you from 'inheriting' a problem.
Pricing
Basic IAQ panel (3 samples + control): $550–$750. Full panel (5 samples + temp/humidity loggers + report): $800–$1,200.
Every quote is fixed after inspection — no hourly billing, no change orders unless the substrate reveals hidden contamination.See full pricing guide →

Air Quality TestingFAQ
Questions homeowners ask about air quality
Mold testing focuses on mold spore counts specifically. IAQ testing can include broader bioaerosol panels, humidity logging, and sometimes VOC/formaldehyde panels. Mold is always a component of IAQ; IAQ is broader than mold.
There's no single number. Generally: indoor mold spore counts comparable to outdoor baseline, humidity 40–60%, CO2 under 1,000 ppm, no detectable formaldehyde (under 0.1 ppm), PM2.5 under 12 µg/m³.
If they're mold-related, yes — through our remediation arm (with separate licensing per NY Article 32). If they're HVAC, duct cleaning, or VOC source issues, we refer to specialists.
Once, unless something changes. A post-remediation verification, a post-construction baseline, or a move-in baseline. Annual testing is usually overkill unless there's an ongoing health concern.

Mold Remediation
Full IICRC S520 remediation — containment, HEPA filtration, removal, and clearance. Our core service. Long Island's housing stock — 1950s–70s construction with limited vapor barriers, poor attic ventilation, and South Shore flood exposure — creates persistent mold conditions that require professional remediation, not surface cleaning. We follow Category 3 containment protocol on every job: negative-air machines with HEPA filtration, zipper-door decontamination chambers, full PPE, and independent post-remediation verification (PRV) clearance before we close out. South Shore towns like Freeport, Merrick, and Valley Stream carry elevated mold risk from storm surge flooding. Nassau County Health Dept guidelines for mold remediation in occupied buildings require written scope, proper containment, and clearance testing on jobs over 10 sqft — we document every step for insurance and compliance purposes. Most residential remediation projects in Nassau and Suffolk run $2,000–$8,000. Post-flood jobs in South Shore towns can run $3,000–$12,000 depending on scope.
