Restoring Homes After Wildfires, Interviews with Practitioners about Common Cleanup Approaches and Knowledge Gaps

Summary

Wildfire smoke and ash contaminate homes, leading to indoor air and surface pollution and persistent odors. This report from Lawrence Berkeley National Laboratory summarizes findings from interviews with 10 remediation companies to understand their common cleanup and odor removal methods. The study, completed in 2026, highlights a consensus on thorough cleaning as a first step but identifies significant differences in opinion regarding the effectiveness and safety of various chemical treatments like ozone or chlorine dioxide, and acknowledges knowledge gaps in how these chemicals transform contaminants. There is a recognized need for clearer understanding and communication about these methods, as well as the impact of insurance companies on remediation scope and laboratory testing.
