ERMI & HERTSMI-2 Dust Testing in Sacramento, CA
qPCR dust analysis, collected correctly and interpreted honestly — for households in Sacramento and across Sacramento County, held to the sensitized-occupant standard and independently verified.
Why this matters in Sacramento
Every market fails in its own way, and Sacramento is no exception. Below: the local failure patterns this service has to account for, and how vetted matching keeps the work honest across Sacramento County.
Valley floor with wet winters, flood-history neighborhoods, and hot dry summers. Mix of raised-foundation older neighborhoods and modern slab tracts; winter crawl-space dampness recurs.
Where the work starts in Sacramento
- Vented crawl-space humidity, insulation contact, and subfloor moisture gradients
- Slab-edge readings and under-slab supply runs at bathrooms and kitchen
- Unvented wall cavities and single-pane condensation zones in original assemblies
- Ground-moisture entry paths in high-water-table and flood-history sections
- Shower and tub assemblies past their service life
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 Sacramento?
Valley floor with wet winters, flood-history neighborhoods, and hot dry summers. Mix of raised-foundation older neighborhoods and modern slab tracts; winter crawl-space dampness recurs. 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.
