Plumber in Portland: an independent guide to costs, permits and hiring

No public agency publishes Portland-only plumbing prices, so the table below uses national ranges from established cost guides. Use it to judge whether a written quote is in a normal range, not as a price anyone has promised you. Access, pipe material, the age of the house and permit fees all move a real quote up or down.

Nights, weekends and holidays cost more. HomeGuide's drain cleaning guide says after-hours emergency rates are often two to three times standard pricing. Our Portland plumber cost guide breaks this down further by job.

Some problems can wait for a weekday estimate. Others get more expensive by the hour.

• Water spreading from a pipe, fitting or tank. Close the main shutoff first. The Portland Water Bureau says most shutoff valves are where the water line enters the house, often at the front near the hose connection, in the basement near the water heater, or in the garage.
• A gas smell near a water heater, furnace or range. Leave the house. NW Natural says to leave no matter what, even if the smell seems mild, and to call its emergency line at 800-882-3377. Call 911 if anyone is in danger.
• Several drains backing up at once, especially a basement floor drain. That usually points to the main building sewer rather than one fixture. Wipes, grease and roots are common causes; see our guide on tree roots in sewer lines.
• A water bill that jumps for no reason, or a spinning leak indicator on the meter. The Water Bureau's leak-finding guide explains the meter test, and our leak detection page covers what a professional search costs.
• An aging tank water heater that leaks, rumbles or delivers rusty water. HomeGuide puts typical tank lifespans at 8 to 12 years.
• Exposed pipes during a freeze, in crawl spaces, garages or exterior walls.

If something is happening right now, our emergency checklist lists the shutoff steps and the official Portland numbers to call.

Oregon uses two licenses for plumbing businesses. According to the Oregon Building Codes Division, contractors doing plumbing work must hold a Construction Contractors Board (CCB) license and the appropriate BCD plumbing contractor license. The CCB says Oregon law generally requires anyone who works for compensation on improvements to real property to be licensed, and it lists plumbing as an example.

1. Search the CCB number in the CCB license search. Confirm the license is active and that the name matches the company on your quote.
2. Search the plumbing license in the BCD license holder search, by business name or license number.
3. Get a written contract that lists the scope, price, materials and the contractor's CCB number.
4. Ask who pulls the permit. In Portland, replacing a water heater or repairing, replacing or moving pipes needs a plumbing permit, with inspections before work is covered.
5. Pay in stages, and hold the final payment until the work has passed inspection.

Our guide to choosing a plumber in Portland has more questions to ask.

The plumbing services overview explains drain cleaning, sewer line repair, leak detection, water heaters and emergency plumbing, each with sourced cost ranges and Portland permit notes. The service area pages cover Beaverton, Gresham, Hillsboro, Lake Oswego, Milwaukie, Oregon City, Tigard and Tualatin, where utilities and permit offices differ from Portland's. The homeowner guides go deeper on old house plumbing, sump pumps and basement flooding, tree roots and costs.

One Portland fact worth knowing: the Portland Water Bureau states that Portland has never had lead service lines. Its main lead concern is copper pipe joined with lead solder, mostly in homes built between 1970 and 1985, and it offers free lead-in-water testing to residential customers.

Portland Plumber Pros is an independent homeowner information website. We are not a plumber or a contractor, we hold no CCB or plumbing license, and we do not perform, price or schedule any work. We have no phone line and no field staff.

What we do: research and explain costs, warning signs, permits and licensing, with a link to the official or published source for every figure. To reach a plumber, call one of the licensed contractors listed on this page or see all listed contractors. Questions about this guide or a correction: email hello@portlandplumberpros.com. We do not take service requests and do not pass messages on to contractors. A reply usually points you to the license lookups and questions on this site. More detail is on our about page, and the contact page explains what to send.
