ERMI & HERTSMI-2 Dust Testing in Dallas, TX
qPCR dust analysis, collected correctly and interpreted honestly — for households in Dallas and across Dallas County, held to the sensitized-occupant standard and independently verified.
Why this matters in Dallas
The service is standard; the building stock is not. What follows is the Dallas-specific picture, plus how households across Dallas County get matched to providers held to the sensitized-occupant standard.
Humid subtropical with severe storm and hail seasons plus occasional deep freezes. Slab-on-clay stock where foundation movement, hail-damaged roofs, and freeze-burst pipes each contribute casework.
Where the work starts in Dallas
- Slab-edge readings and under-slab supply runs at bathrooms and kitchen
- Shower and tub assemblies past their service life
- Water-heater closets and laundry connections
- Attic-side bath-fan ducting and termination
What's included
- Collection planning: composite versus room-specific sampling matched to the question
- Proper collection sites: undisturbed dust reservoirs, not floors or fresh surfaces
- Accredited-lab qPCR analysis of water-damage and outdoor marker species
- Species-level interpretation against building findings, not just the composite score
- Baseline documentation for valid post-remediation comparison
- A single hallway air cassette sold as a building screen
- Scores interpreted without any building context
- No documentation of collection sites and method
A defensible answer to 'is this building a problem' with species-level detail that directs the inspection — and a baseline your final clearance will be measured against.

Why does local building knowledge matter in Dallas?
Humid subtropical with severe storm and hail seasons plus occasional deep freezes. Slab-on-clay stock where foundation movement, hail-damaged roofs, and freeze-burst pipes each contribute casework. Providers who work these exact failure modes find sources faster and scope work more accurately than generalists applying a national template.
What standard is the work held to?
The sensitized-occupant standard: written scopes, verified negative-pressure containment where remediation is involved, no fogging or biocide-and-leave treatments, chemical disclosure, and third-party verification as the release condition for final payment.
