qPCR dust analysis, collected correctly and interpreted honestly — for households in Fairfield and across Solano County, held to the sensitized-occupant standard and independently verified.
Why this matters in Fairfield
Generic national advice breaks on local construction. This page maps the service to how Fairfield homes are actually built — and to providers serving Solano County who work these exact failure modes.
Wind-gap city where delta breeze and winter fog meet valley heat. Post-war and modern tracts; wind-driven winter rain finds every unmaintained penetration on west-facing elevations.
Where the work starts in Fairfield
- Fog-side and north-facing elevations for chronic condensation loading
- Ground-moisture entry paths in high-water-table and flood-history sections
- Wind-driven rain entry at exposed elevations and unmaintained penetrations
- Shower and tub assemblies past their service life
- Water-heater closets and laundry connections
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.
