Lab-Certified Mold Testing
for Randolph, MN Properties

The workhorse of mold air testing. Fast turnaround (24–48hr), genus-level ID, quantified indoor vs. outdoor comparison. Appropriate for most routine Randolph residential and commercial testing scenarios.

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 Randolph, MN use case.

Surface sampling confirms whether visible discoloration in your Randolph property is actually mold (not staining or efflorescence) and identifies the species present — affecting which removal protocol and PPE level is appropriate.

ERMI provides a historical record of mold accumulation — not just what's airborne right now. Useful in Randolph properties where symptoms are present but spore trap sampling comes back normal, or for verifying long-term post-remediation success.

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 Randolph building.

Independent post-remediation testing compares treated zone air samples to outdoor baseline — confirming indoor spore counts returned to acceptable levels before re-occupancy. Our Randolph, MN clearance testing uses the same accredited lab protocol as pre-remediation sampling, producing directly comparable data that demonstrates the remediation achieved its objective.
