HVAC Decontamination in San Rafael, CA
Opening, assessing, and restoring the system that touches every room — for households in San Rafael and across Marin County, held to the sensitized-occupant standard and independently verified.
Why this matters in San Rafael
Generic national advice breaks on local construction. This page maps the service to how San Rafael homes are actually built — and to providers serving Marin County who work these exact failure modes.
Marin fog and heavy winter rain with steep hillside lots draining against foundations. Hillside homes with downhill foundation walls, canyon properties under tree canopy, and canal-district flats near sea level — high-touch assessment territory.
Where the work starts in San Rafael

Why does local building knowledge matter in San Rafael?
Marin fog and heavy winter rain with steep hillside lots draining against foundations. Hillside homes with downhill foundation walls, canyon properties under tree canopy, and canal-district flats near sea level — high-touch assessment territory.

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.
