Discovering high formaldehyde levels doesn’t mean immediate panic, but it requires prompt action to protect occupant health. Solutions may include improving ventilation, removing contaminated materials, sealing surfaces to reduce off-gassing, or replacing problematic products with safer alternatives. Professional testing provides specific recommendations based on contamination sources and concentration levels. For commercial buildings, mitigation may be required for employee safety and regulatory compliance. Documentation from professional testing supports warranty claims against manufacturers and provides evidence for insurance purposes. The key is addressing problems quickly to minimize health risks and prevent long-term exposure.
