Instrumented, independent assessment of the full moisture envelope — for households in Napa and across Napa County, held to the sensitized-occupant standard and independently verified.
Why this matters in Napa
The service is standard; the building stock is not. What follows is the Napa-specific picture, plus how households across Napa County get matched to providers held to the sensitized-occupant standard.
River-valley floor with winter fog, flood-history districts, and damp cold-season soil. Historic downtown Victorians on raised foundations with chronically damp winter crawl spaces, plus wine-country remodels layered over old assemblies.

River-valley floor with winter fog, flood-history districts, and damp cold-season soil. Historic downtown Victorians on raised foundations with chronically damp winter crawl spaces, plus wine-country remodels layered over old assemblies. 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.
