Quick answer
Ask for the plumber's Oregon CCB license number and check it at ccb.state.or.us, compare 2–3 written quotes, and look at both Google rating and review count.
Hiring the right plumber saves money and headaches. In Oregon, contractors must be licensed with the Construction Contractors Board (CCB) and show their license number in their ads. Here's a quick checklist before you hire.

Step 1: Check the license
- Ask for the CCB license number — Oregon contractors must put it on their websites, ads and business cards.
- Look it up on the CCB license search at ccb.state.or.us. Searching by license number is the most accurate.
- Can't find them by name? Try a shorter name or different spelling before assuming they're unlicensed.
- Individual plumber licenses can be checked with the Oregon Building Codes Division license search.
- CCB customer service: (503) 378-4621.
Step 2: Compare written quotes
- Get at least 2–3 written quotes for bigger jobs.
- Make sure each quote covers the same work, parts and permits.
- Check Google ratings and the number of reviews — a 4.8 from 900 reviews tells you more than a 5.0 from 5.
Typical Portland plumber rates run about $85–$165 per hour — see our plumbing cost guide for job-by-job prices.
