Inland North County valley heat with winter rain. Mixed-era stock from ranchos to 2000s tracts; roof and HVAC condensate issues recur.

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
