Independent third-party assessment prevents conflicts of interest that can occur when restoration contractors also perform assessments, as contractors may have financial incentives to either over-treat or under-treat damage. Independent assessment ensures that restoration decisions are based on scientific evaluation rather than cost-cutting measures or profit maximization. Professional independent oversight provides objective evaluation of water categories, affected areas, and necessary restoration procedures without bias toward specific restoration approaches. This objectivity protects both immediate health and long-term property value while providing crucial documentation for insurance claims and potential liability issues.
