How to hire a plumber in Hillsboro
Plumbing is one of the few trades where a bad hire can cause five figures of water damage. A few minutes of checking up front is genuinely worth it.
- Decide if it's an emergency. An active leak, sewage backup, or no water at all means you want someone offering same-day service. Anything else — a slow drain, a remodel, a water heater nearing end of life — can wait for a properly vetted quote.
- Verify the license twice. Plumbing businesses in Oregon need both a CCB license and a BCD plumbing contractor license. Check both (details below).
- Get the scope in writing. Ask what's included: parts, labor, permit fees, haul-away, and whether diagnostic time is credited toward the repair.
- Ask about permits. Water heater replacements, repiping, and sewer line work typically require a permit and inspection in Oregon. A plumber who suggests skipping it is a hard no.
- Compare at least two quotes for non-emergency work — and compare the scope, not just the total. The cheaper bid often excludes the permit or the haul-away.
- Confirm the warranty. Ask how long parts and labor are covered, and get it on the invoice rather than a verbal promise.
Verifying an Oregon plumbing license
In Oregon, anyone doing construction work for pay must be licensed with the Construction Contractors Board (CCB), and must show their CCB number on ads, estimates, contracts and invoices. Before hiring, look the number up at search.ccb.state.or.us and confirm the license is active, the bond is current, and liability insurance is in place. CCB licenses renew every two years.
Plumbing and electrical work carry an extra requirement: the business also needs the appropriate Building Codes Division (BCD) contractor license, separate from the CCB. You can check it at oregon.gov/bcd. A company can hold a valid CCB license and still not be licensed for this specific trade — worth two minutes to verify.
Red flags when hiring a plumber
None of these automatically mean bad work — but each is worth a second question before you sign anything.
- No CCB number anywhere on their website, truck, or estimate — Oregon requires it be displayed.
- Pressure to decide immediately, or a quote that expires “today only.”
- Asking for full payment up front, or cash-only with no written invoice.
- Suggesting you skip a permit to save money on water heater or sewer work.
- A diagnosis of “you need a full repipe” without showing you the actual problem.
- No proof of liability insurance when you ask for it.
