Mold Remediation in San Diego, California
For mold in a San Diego home, use California Public Health’s moisture and mold resources to plan source repair, cleanup, and communication between owners and occupants. A dry outdoor period does not resolve water trapped behind finishes after a pipe leak. Photograph the affected area, identify active wetting, and avoid painting over growth before the moisture problem is corrected.
