Visible Mold Next-Step Assessment in San Mateo

Ask how moisture sources, confirmation needs and material-specific options will be assessed by the appropriate professionals. Keep the findings and proposed next steps distinct from an assurance that cleaning alone resolves the concern.

EPA says sampling is often unnecessary where mold growth is visible. Ask an experienced professional what uncertainty a proposed test would resolve and how its result would change the work. Testing is not a substitute for documenting the observed condition.

EPA emphasizes correcting the water problem as well as addressing mold. Ask the assessment to identify the moisture concern and who will investigate it, rather than treating a clean-looking surface as proof that the cause is resolved.

EPA advises against running an HVAC system known or suspected to be contaminated with mold because it could spread contamination. Contact an experienced professional for the system assessment; discuss health concerns with a health professional.
