Different questions require different sampling methods. We help you choose the right test for your specific situation — not a default package that applies regardless of context.
Non-Viable
💨Spore Trap Air Sampling
Spore trap cassettes collect all airborne particles — viable and non-viable — and are analyzed under microscopy for mold genus identification and spore concentration. Results typically return in 24–48 hours from an accredited lab. Compared against an outdoor baseline, this data shows whether indoor spore counts are elevated and which genera are present. Standard method for routine Lawrence, MA residential and commercial air quality assessment.
Viable
🏭Viable Culture Air Sampling
When genus ID isn't enough, viable culture plates give species-level confirmation. Critical for Stachybotrys chartarum investigation and situations where CFU counts and exact species matter — typically health-concern investigations and some insurance scenarios in Lawrence, MA.
Surface
🎖Surface Swab & Tape Lift Sampling
Surface sampling confirms whether visible discoloration in your Lawrence property is actually mold (not staining or efflorescence) and identifies the species present — affecting which removal protocol and PPE level is appropriate.
ERMI
🔋ERMI Floor Dust Sampling
ERMI provides a historical record of mold accumulation — not just what's airborne right now. Useful in Lawrence properties where symptoms are present but spore trap sampling comes back normal, or for verifying long-term post-remediation success.
HVAC
🏢HVAC Register & Return Air Testing
Testing directly at HVAC supply registers and return grilles identifies whether the air distribution system is distributing mold spores throughout the property. Elevated counts at registers compared to room-level samples confirm the AHU or ductwork as the amplification source — critical before any duct cleaning or coil remediation decision in your Lawrence building.
Clearance
📄Post-Remediation Clearance Testing
Independent post-remediation testing compares treated zone air samples to outdoor baseline — confirming indoor spore counts returned to acceptable levels before re-occupancy. Our Lawrence, MA clearance testing uses the same accredited lab protocol as pre-remediation sampling, producing directly comparable data that demonstrates the remediation achieved its objective.
