Different questions require different sampling methods. We help you choose the right test for your specific situation — not a default package that applies regardless of context.
Non-Viable
💨Spore Trap Air Sampling
Spore trap cassettes collect all airborne particles — viable and non-viable — and are analyzed under microscopy for mold genus identification and spore concentration. Results typically return in 24–48 hours from an accredited lab. Compared against an outdoor baseline, this data shows whether indoor spore counts are elevated and which genera are present. Standard method for routine Irving, TX residential and commercial air quality assessment.
Viable
🏭Viable Culture Air Sampling
When genus ID isn't enough, viable culture plates give species-level confirmation. Critical for Stachybotrys chartarum investigation and situations where CFU counts and exact species matter — typically health-concern investigations and some insurance scenarios in Irving, TX.
Surface
🎖Surface Swab & Tape Lift Sampling
Surface swab samples from visible growth areas are sent to an accredited lab for culture analysis or direct microscopy — confirming whether visible discoloration is mold and identifying the genus/species. Tape lifts provide a faster direct-microscopy option for surface assessment. Used when the presence of mold on a specific surface needs to be confirmed and identified before committing to a removal scope.
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 Irving, TX 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 Irving, TX 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
Independent post-remediation testing compares treated zone air samples to outdoor baseline — confirming indoor spore counts returned to acceptable levels before re-occupancy. Our Irving, TX clearance testing uses the same accredited lab protocol as pre-remediation sampling, producing directly comparable data that demonstrates the remediation achieved its objective.
