Every testing scenario covered with accredited methodology.
💨
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 Churchton residential and commercial testing scenarios.
🏭
Viable Culture Air Sampling
When genus-level ID isn't enough, viable culture plates give you species confirmation. Critical for Stachybotrys chartarum investigation and occupational health documentation in Churchton, MD.
🎖
Surface Swab & Tape Lift Sampling
Surface sampling from visible staining in your Churchton property confirms whether it's mold (not just discoloration) and which species — important for remediation protocol decisions.
📄
Post-Remediation Clearance Testing
After mold remediation, clearance testing compares treated zone air samples to outdoor baseline — confirming indoor spore counts are back to acceptable levels before re-occupancy. Our Churchton, MD clearance testing uses the same accredited lab protocol as pre-remediation sampling, so results are directly comparable.
🏢
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 Churchton.
🔋
Bulk & ERMI Sampling
Bulk material samples and ERMI (Environmental Relative Moldiness Index) floor dust sampling give a cumulative picture of historical mold presence in a Churchton, MD property. ERMI uses qPCR analysis on settled dust to identify 36 mold species — often used in post-remediation verification or occupant health investigations.
