Each method below produces different data. We explain which is appropriate for your Gainesville, VA 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 Gainesville 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 Gainesville, VA use case.
Surface
🎖Surface Swab & Tape Lift Sampling
Surface swab samples from visible growth areas are sent to an accredited lab for culture analysis or direct microscopy — confirming whether visible discoloration is mold and identifying the genus/species. Tape lifts provide a faster direct-microscopy option for surface assessment. Used when the presence of mold on a specific surface needs to be confirmed and identified before committing to a removal scope.
ERMI
🔋ERMI Floor Dust Sampling
ERMI provides a historical record of mold accumulation — not just what's airborne right now. Useful in Gainesville 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
Register-versus-room comparative sampling confirms whether your Gainesville, VA HVAC system is a mold amplifier. Knowing before spending on duct cleaning whether cleaning will actually help is worth the testing cost.
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 Gainesville, VA clearance testing uses the same accredited lab protocol as pre-remediation sampling, producing directly comparable data that demonstrates the remediation achieved its objective.
