What Washington requires
Washington does not have a specific mold remediation license, but contractors must be registered with the Washington State Department of Labor and Industries and hold appropriate contractor credentials. Washington has strong environmental and worker safety regulations that apply to mold work. Washington OSHA has occupational exposure guidelines for mold remediation workers.
Standard homeowner policies in Washington generally cover mold from sudden water damage. Western Washington's wet climate makes mold a persistent concern, while eastern Washington's dry climate presents lower risk. Homeowners in rain-heavy areas should review their mold coverage limits carefully.
