Each method below produces different data. We explain which is appropriate for your Cottage Grove, MN property situation before you commit.
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 Cottage Grove residential and commercial testing scenarios.
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 Cottage Grove, MN.
Surface
🎖Surface Swab & Tape Lift Sampling
Surface sampling confirms whether visible discoloration in your Cottage Grove 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 Cottage Grove 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 Cottage Grove building.
Clearance
📄Post-Remediation Clearance Testing
Post-remediation clearance testing for any Cottage Grove property — whether we did the remediation or another contractor did. Written clearance report from an independent accredited lab confirms the job is objectively complete.
