L&I Contractor Registration
L&I says all construction contractors in Washington register with it. Its application lists the specialty "SE Construction, fire or water damage clean-up." Use L&I's contractor verification tool to look up the company before you sign.
L&I lists a $30,000 bond for general contractors and a $15,000 bond for specialty contractors, plus liability insurance of $200,000 and $50,000, or $250,000 combined.
