ERMI & HERTSMI-2 Dust Testing in Palo Alto, CA
qPCR dust analysis, collected correctly and interpreted honestly — for households in Palo Alto and across Santa Clara County, held to the sensitized-occupant standard and independently verified.
Why this matters in Palo Alto
The service is standard; the building stock is not. What follows is the Palo Alto-specific picture, plus how households across Santa Clara County get matched to providers held to the sensitized-occupant standard.
Creek-adjacent flats with winter rain, mature tree canopy, and high-value remodel churn. Eichler-era and pre-war stock where flat roofs, radiant slabs, and remodel-over-remodel layering create concealed moisture paths that only instruments find.
Where the work starts in Palo Alto
- Slab-edge readings and under-slab supply runs at bathrooms and kitchen
- Flat-roof drains, scuppers, and ponding history above ceiling stains
- Ground-moisture entry paths in high-water-table and flood-history sections
- Remodel-era transitions where new finishes were layered over old assemblies
- 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 Palo Alto?
Creek-adjacent flats with winter rain, mature tree canopy, and high-value remodel churn. Eichler-era and pre-war stock where flat roofs, radiant slabs, and remodel-over-remodel layering create concealed moisture paths that only instruments find. 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.
