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