From basic air quality screening to forensic-level fungal investigation — the right test for your situation.
💨
Non-Viable Spore Trap Air Sampling
The workhorse of mold air testing. Spore traps collect non-viable particles — both live and dead spores — giving total spore counts by genus. Standard for most Markham residential and commercial testing scenarios.
🏭
Viable Culture Air Sampling
Culture plates capture live, culturable mold spores that then grow in the lab — allowing species-level identification and colony-forming unit counts. Used when species-level data matters: occupational health concerns, Stachybotrys investigation, or situations where genus-level data from spore traps isn't sufficient for your Markham, VA use case.
🎖
Surface Swab & Tape Lift Sampling
Surface sampling from visible staining in your Markham property confirms whether it's mold (not just discoloration) and which species — important for remediation protocol decisions.
📄
Post-Remediation Clearance Testing
Independent clearance testing after any Markham, VA remediation job — whether we did the work or another contractor did. Lab report confirms the job is objectively complete.
🏢
HVAC & Ductwork Air Testing
Testing at HVAC registers and returns identifies whether the air distribution system is a mold source. High spore counts at registers compared to room-level samples indicate the system is contributing to indoor air quality problems — a critical finding before any duct cleaning or coil remediation decision in Markham.
🔋
Bulk & ERMI Sampling
ERMI dust sampling for your Markham property gives a historical picture of mold accumulation — useful when symptoms are present but air sampling comes back normal, or when assessing long-term remediation success.
