Water damage & mold help in California
California's water damage risks are distinctive. Winter atmospheric rivers bring heavy rain and flooding, as in the 2023 storm series. Wildfires cause fire and smoke damage across large areas, including the January 2025 Los Angeles fires. Earthquakes can break pipes and water heaters. Coastal fog and older homes with poor ventilation add mold risk.
