You will have your job done by a journeyman plumber, not by new individuals just learning the trade. What does it mean? Oregon law requires business entities or individuals conducting construction activities within the State of Oregon to be licensed with the CCB. A license means the contractor has a surety bond and liability and property damage insurance. Once I saw the quality of his work and the lower cost, I decided to hire him for extra work. He was prompt, efficient, and affordable. I will definitely keep his card for future plumbing needs.
