From basic air quality screening to forensic-level fungal investigation — the right test for your situation.
💨
Non-Viable Spore Trap Air Sampling
Spore trap cassettes collect airborne particles that are then analyzed under microscopy to identify mold genera and count spore concentrations. Compared against an outdoor baseline sample, this data shows whether indoor spore counts are elevated and which genera are present. Fastest turnaround for routine Ridgefield, WA air quality assessment.
🏭
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 Ridgefield, WA use case.
🎖
Surface Swab & Tape Lift Sampling
Surface sampling from visible staining in your Ridgefield 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 Ridgefield, WA clearance testing uses the same accredited lab protocol as pre-remediation sampling, so results are directly comparable.
🏢
HVAC & Ductwork Air Testing
Register-versus-room comparative sampling identifies whether your Ridgefield, WA HVAC system is amplifying or distributing mold — essential before deciding whether duct cleaning will actually help.
🔋
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 Ridgefield, WA property. ERMI uses qPCR analysis on settled dust to identify 36 mold species — often used in post-remediation verification or occupant health investigations.
