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
The workhorse of mold air testing. Fast turnaround (24–48hr), genus-level ID, quantified indoor vs. outdoor comparison. Appropriate for most routine Lancaster residential and commercial testing scenarios.
Viable
🏭Viable Culture Air Sampling
Viable culture plates capture live, culturable mold spores that grow on culture media — allowing species-level identification and colony-forming unit counts. Results take 5–7 business days but provide species-level data that spore traps can't. Used when species-level identification matters: Stachybotrys confirmation, occupational health documentation, or situations where genus-level data from spore traps isn't sufficient for your Lancaster, PA use case.
Surface
🎖Surface Swab & Tape Lift Sampling
Surface sampling confirms whether visible discoloration in your Lancaster 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 Lancaster 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 Lancaster 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 Lancaster, PA clearance testing uses the same accredited lab protocol as pre-remediation sampling, producing directly comparable data that demonstrates the remediation achieved its objective.
