Each method below produces different data. We explain which is appropriate for your Unionville, PA 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 Unionville 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 Unionville, PA use case.
Surface
🎖Surface Swab & Tape Lift Sampling
Surface sampling confirms whether visible discoloration in your Unionville 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 Unionville, PA 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
Register-versus-room comparative sampling confirms whether your Unionville, PA 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
Post-remediation clearance testing for any Unionville property — whether we did the remediation or another contractor did. Written clearance report from an independent accredited lab confirms the job is objectively complete.
