Why Choose Us — Austin, TX

Why Our Austin, TX Mold Testing Produces Meaningful Results

Method selection, baseline collection, COC documentation, and use-case report format — every job, every time.

Outdoor Baseline Collected Every Job
Mold spore concentrations vary enormously by season, weather conditions, and regional vegetation in Austin, TX. An indoor spore count compared to no baseline is uninterpretable — you can't know if 400 Cladosporium spores/m³ is elevated for your specific Austin location on that day without knowing what the outdoor count was simultaneously. We collect outdoor comparative samples on every Austin, TX testing job.
Method Matched to the Question
Four methods, four different questions. We explain which method addresses your specific Austin, TX testing scenario before you commit to sampling.
Chain of Custody on Every Sample
COC form completed at every sampling event. Sample integrity documented from collection through lab receipt. Required for results to be legally defensible in Austin, TX.
Accredited Lab Partner — Not In-House
Accredited laboratory partner for every Austin, TX testing job. Individual lab accreditation documented. Not in-house analysis or unaccredited third-party processing.

Testing Methods — Austin, TX

Six Mold Testing Methods Available in Austin, TX

The sampling method determines what question gets answered. We match method to question — and explain the difference before booking.

Spore Trap
💨
Spore Trap Air Sampling
Standard routine screening method. 24–48hr results. Genus ID and spore counts. Outdoor baseline included. Appropriate for most routine Austin and Austin, TX residential and commercial scenarios.
24-48hr Results
Genus ID
Outdoor Baseline
Viable Culture
🏭
Viable Air Culture Sampling
Viable culture plates capture live, culturable mold spores and grow them on culture media for species-level identification and CFU counting. Takes 5–7 business days for results but provides species confirmation that spore traps can't. Required for: health-complaint investigations where species matters clinically; Stachybotrys chartarum confirmation; occupational health documentation; and some insurance use cases in Austin, TX.
Species-Level ID
CFU Count
5-7 Business Days
ERMI
🔋
ERMI Floor Dust Sampling
Environmental Relative Moldiness Index (ERMI) analysis uses qPCR on settled floor dust to identify and quantify 36 specific mold species — providing a historical picture of mold accumulation over time rather than a snapshot of current airborne conditions. Useful when current air sampling is normal but historical mold events are suspected, or when post-remediation verification of long-term success is needed.

Bulk Material Sampling
Bulk material samples — pieces of suspected contaminated material (drywall, ceiling tile, insulation) sent to the accredited lab for culture analysis — confirm whether visible discoloration is mold and identify the species. Used when surface appearance is ambiguous or when species ID on a specific material is needed before removal protocol selection.

HVAC Register Comparative Sampling
Sampling at HVAC supply registers and compared to room-level samples identifies whether the air handling system is amplifying or distributing mold. Elevated register counts versus room counts confirm the system is the source — critical before duct cleaning decisions in Austin commercial and larger residential properties.

Mold Testing Reviews From Austin, TX

★★★★★
The outdoor comparative sample is what made the difference. Another testing company gave us an indoor spore count with no context. Cheap Mold Removal collected an outdoor sample simultaneously and the indoor count in our Austin master bedroom was 8x the outdoor count in the same genera — that comparison is what gave our doctor the environmental data that mattered.

★★★★★
HVAC register sampling before committing to duct cleaning for our Austin office building. Register counts vs. room counts confirmed the AHU coil was the amplification source — not the ductwork. That data saved us from duct cleaning that wouldn't have helped and directed the budget toward coil remediation that actually addressed the source.
Tim W.
Facilities director, Austin, TX
★★★★★
Bulk material sampling confirmed the dark staining on our Austin basement ceiling tiles was Aspergillus niger — not Stachybotrys as we'd feared. Different species, different removal protocol. That confirmation changed both the PPE requirement and the disposal approach. The right test before the wrong remediation protocol saved us about $3,000 in unnecessary enhanced containment costs.

FAQ — Mold Testing in Austin, TX

What Austin Clients Ask About Air Quality Testing

Mold spores are naturally present in outdoor air everywhere — the outdoor concentration varies enormously by season, weather, and regional vegetation, and it's different on a dry fall afternoon than on a humid summer morning in the same Austin location. Without knowing what the outdoor concentration is on the same day as the indoor sample, you can't determine whether the indoor count is elevated relative to background. A count of 500 Cladosporium spores/m³ might be normal if the outdoor count that day is 600, or it might indicate a problem if the outdoor count is 40. The comparison is what produces a finding — not the raw number alone.
ERMI (Environmental Relative Moldiness Index) uses qPCR analysis on settled floor dust to identify and quantify 36 specific mold species. Because settled dust accumulates over time, ERMI reflects the historical mold load in the property — not just what's airborne at the moment of sampling. This makes ERMI appropriate for: properties where current air sampling is normal but past mold events are suspected; post-remediation verification when you want to confirm long-term improvement, not just current-condition clearance; and properties where current airborne counts fluctuate with weather and ventilation in ways that make point-in-time sampling unreliable.
Outdoor baseline, chain of custody, accredited lab, use-case report format, AIHA-method compliance. These five factors separate meaningful testing from results that look official but can't be used for the purpose you need them for.
Minimum three samples for an interpretable result: outdoor comparative, area of concern, unaffected reference area. Scope scales with property size and question. We explain the specific sampling plan before you book.
For insurance purposes, mold test results need to: (1) establish that elevated mold conditions exist (indoor-to-outdoor baseline comparison); (2) identify the mold genera/species present; (3) correlate with a covered water event that caused the moisture condition; and (4) be produced by an accredited lab under chain of custody to be credible to the adjuster. Our Austin, TX testing documentation includes all four elements, and the written report is formatted to provide adjusters what they need to evaluate the claim without requesting additional documentation.
