ERMI & HERTSMI-2 Dust Testing in Oakland, CA
qPCR dust analysis, collected correctly and interpreted honestly — for households in Oakland and across Alameda County, held to the sensitized-occupant standard and independently verified.
Why this matters in Oakland
Local building knowledge is the difference between finding the source and billing for a search. Here is how the Oakland housing picture shapes this work, and how matching gets it done to a written standard across Alameda County.
Bay-influenced humidity with wet winters; hill neighborhoods add hillside drainage against foundations. Craftsman-era stock with basements and post-and-pier crawl spaces that stay damp through winter.
Where the work starts in Oakland
- Vented crawl-space humidity, insulation contact, and subfloor moisture gradients
- Basement wall moisture and slab-to-wall joints below grade
- Fog-side and north-facing elevations for chronic condensation loading
- Uphill foundation walls and surface-drainage paths against the structure
- Unvented wall cavities and single-pane condensation zones in original assemblies
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 Oakland?
Bay-influenced humidity with wet winters; hill neighborhoods add hillside drainage against foundations. Craftsman-era stock with basements and post-and-pier crawl spaces that stay damp through winter. 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.
