ERMI & HERTSMI-2 Dust Testing in Chula Vista, CA

qPCR dust analysis, collected correctly and interpreted honestly — for households in Chula Vista and across San Diego County, held to the sensitized-occupant standard and independently verified.

Why this matters in Chula Vista

Every market fails in its own way, and Chula Vista is no exception. Below: the local failure patterns this service has to account for, and how vetted matching keeps the work honest across San Diego County.

South Bay marine influence with canyon drainage patterns. Mix of mid-century slab homes and 2000s stucco tracts with window-flashing vintages worth checking.

Where the work starts in Chula Vista

  • Slab-edge readings and under-slab supply runs at bathrooms and kitchen
  • Fog-side and north-facing elevations for chronic condensation loading
  • Stucco penetrations, weep screeds, and window-flashing terminations
  • 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
RED FLAGS WE SCREEN OUT
  • A single hallway air cassette sold as a building screen
  • Scores interpreted without any building context
  • No documentation of collection sites and method
THE OUTCOME

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.
