Verify the contracting identity
Ask for the legal business name and applicable Washington registration information. Use L&I’s Verify tool to check the record and ask about insurance for the proposed work. This website does not certify contractors or guarantee their work.
Define the assessment and authority
Confirm the address, service fit, availability and any charge before booking. Identify who may authorize work in a rented or shared building. Ask whether the first visit is only an assessment or may begin chargeable work.
Compare scope and responsibility
Ask who handles source repair, extraction, drying, disposal and rebuilding. Request exclusions and the approval process for additional work. Use the scope comparison guide to organize those answers.
Agree on records and communication
Identify the person who explains progress and provides completion notes. Keep authorizations, photographs and receipts. Ask how access will be managed and how adjoining occupied areas will be protected.
Connect the guidance to the service
Review water extraction before discussing the assessment. Confirm the business, address availability, charges and written scope directly.
