Older homes, additions, and remodeled rooms can hide different generations of plumbing. A newer home has its own needs. We start with the actual property—not assumptions about what is behind the walls.

When it can’t wait

Safety comes first.

If water is actively escaping, shut off the supply only if you can do so safely, and call the office. An online request is not an emergency dispatch channel.

For immediate danger or a suspected gas leak, leave the area and contact emergency services or your gas utility from a safe location.

Contact our office

Where is Northwest Plumbing Services located?

Our showroom is at 1271 Columbia Blvd, St. Helens, OR 97051. Mail may be sent to PO Box 492, St. Helens, OR 97051.

How do I request plumbing service?

Call (503) 366-1323 or email office@nwplumbingservices.com. Tell us what is happening, where it is located, and whether water is actively leaking so the office can guide the conversation.

What water heaters does Northwest Plumbing Services work with?

The company offers tank and tankless water-heater service. Contact the office with your current system details so the available repair or installation approach can be confirmed.

When should I call about a water heater?

Call when hot water becomes inconsistent, the unit makes unusual noises, or you notice moisture or a leak. If water is actively escaping, shut off the supply when it is safe and contact the office.

Does every recurring leak require a whole-home repipe?

No. Recurring leaks can signal broader pipe problems, but a professional assessment is needed to determine whether targeted repair, section replacement, or a larger repiping plan is appropriate.

Can repiping be part of a remodel or new construction project?

Yes. Northwest Plumbing Services offers remodel and new-construction plumbing, and repiping can be discussed as part of the project’s layout, fixture, and access planning.
