Each method below produces different data. We explain which is appropriate for your Riverdale, IL 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 Riverdale 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 Riverdale, IL.
Surface
🎖Surface Swab & Tape Lift Sampling
Surface sampling confirms whether visible discoloration in your Riverdale 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
Environmental Relative Moldiness Index (ERMI) sampling uses qPCR analysis on settled floor dust to identify and quantify 36 specific mold species — providing a historical picture of mold accumulation in a Riverdale, IL property rather than a snapshot of current airborne levels. Used for post-remediation verification, long-term occupant health investigation, and situations where previous mold activity may have settled into dust but isn't actively airborne.
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 Riverdale building.
Clearance
📄Post-Remediation Clearance Testing
Post-remediation clearance testing for any Riverdale property — whether we did the remediation or another contractor did. Written clearance report from an independent accredited lab confirms the job is objectively complete.
