Mold Air Quality Testing · California
Do I need air testing if I already see mold?
Short answer
Yes, air testing is recommended even if mold is visible. It determines if the spores have spread to other rooms through the HVAC system and establishes a baseline to ensure the air is safe after the mold is removed.
Seeing mold on a wall is just the tip of the iceberg. Air testing tells us how many microscopic spores you are actually breathing in and whether the contamination is localized or systemic. ClearPoint Environmental provides this data so you can determine if you need a simple surface cleaning or a full-scale professional remediation with containment. After remediation, we also offer 'clearance testing' to prove that the air quality has returned to normal levels.
