Verify the contractor is insured against possible damage.
Look up a contractor’s license history for license violations.
A contractor registration is required by the State of Washington if a homeowner project involves any work that increases or decreases the value of real estate or consulting on a construction project. Contractors are not required to be registered if the customer needs gutter cleaning or pruning or lawn care or window washing to be performed.
