Overview
Mold Testing: what we actually do.
Mold testing is the lab component of assessment — used when visual inspection alone can't answer the question. The most common uses: confirming Stachybotrys before a major remediation, establishing a pre-remediation baseline, post-remediation verification (PRV), and legal disputes where samples need chain-of-custody.
When to call us
- Confirm or rule out Stachybotrys (toxic black mold) before remediation
- Post-remediation verification clearance testing (PRV)
- Health-complaint investigation with no visible mold
- Tenant-landlord legal dispute requiring admissible samples
- Indoor air quality (IAQ) baseline for asthma or sensitivity concerns
Our process
01
Sampling plan
Determine which rooms, which heights, which comparisons (indoor vs outdoor, affected vs unaffected). AIHA protocols drive this.
02
Air cassette pumps
Air samples at 15 L/min for 5–10 minutes per location. Sealed cassettes with chain-of-custody forms.
03
Surface swabs
If visible growth is present, direct swabs or tape-lifts from suspect areas.
04
Lab processing
Sealed, logged, shipped same day to the AIHA-accredited lab. 3–5 business day standard turnaround, 24-hour rush available.
05
Results + interpretation
You receive the lab report directly. We provide interpretation: what the numbers mean, whether they exceed normal outdoor baseline, whether remediation is warranted.
The real causes we see in Long Island homes
Asthma flare-ups
Parents trying to figure out why a child's asthma is worse at home than at school. Air-sampling a child's bedroom often reveals elevated Pen/Asp from a hidden leak.
Real-estate disputes
Buyer's inspector flagged mold; seller disputes the scope. Independent third-party testing resolves the question.
Post-remediation verification
Every remediation of 10+ sqft should end with PRV clearance testing. Independent (us) versus same-company (not us) — we're the independent option.
Pricing
Two-point air sample (inside + outside): $450–$650. Full IAQ panel (5 samples + 2 swabs): $700–$950. Rush 24-hour turnaround: add $200.
Every quote is fixed after inspection — no hourly billing, no change orders unless the substrate reveals hidden contamination.See full pricing guide →

FAQ
Questions homeowners ask about testing
The drugstore kits are borderline useless — they grow whatever lands on them, including normal outdoor spores, and don't quantify. For any meaningful result, you need pump-sampled cassettes sent to an accredited lab.
There's no legal threshold. The standard interpretation: interior spore counts significantly above outdoor control suggest an indoor source. Species matter: Stachybotrys and Chaetomium are never normal indoors.
About 30 days. After that, conditions (humidity, HVAC, occupancy) can change enough that the baseline shifts.
No — visual inspection and lab testing are billed separately. Most clients bundle: inspection + 2-3 air samples is common.

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.
