Professional water loss assessment provides comprehensive documentation including water categorization, moisture mapping results, affected area identification, and specific restoration requirements based on contamination levels. Post-restoration verification conducts comprehensive testing to verify that affected areas are properly dried and free from contaminants before reoccupancy. Independent verification provides documentation that restoration objectives have been achieved and meets industry standards for health protection. This documentation supports insurance claims, demonstrates compliance with health and safety requirements, and provides liability protection by proving that restoration was based on scientific assessment and proper protocols.
