A real person answers 7 days a week, 7am to 5pm. We confirm an arrival window that actually works for you.
We diagnose
We pressure test the system to confirm there is a leak and to narrow down where it is before opening anything.

One number, parts and labor, approved before we start. No surprise line items.
We fix it and clean up
We repair or replace the affected section, retest, and meet the inspector where the work requires it.
Straight pricing, no surprises
You get a flat quote before any work starts, and it does not change once we are in the wall. The diagnostic fee is credited toward the repair. For full replacements we offer financing, so a failed tank does not have to turn into a bad month.

Read all 51 reviews on GoogleMy hot water heater fizzled on me Saturday and I called this morning. Christina said Alex could come out today, which was great. She checked out what was wrong and said she could replace it today. Which she did. I was impressed how she got the work done. And I got hot water! Yay! I will Definitely use them in the future, and I will refer them to friends and family. Great to support a local woman owned an operated business.
Alex and the team at Northwest Plumbing are outstanding. We had an emergency with a significant leak on our side of the city water main, discovered first thing the morning by city crews. I reached out to Northwest via their web interface, and Alex and her office team both called back within an hour and a half. She had availability (thankfully!) in the afternoon, and we were fully fixed and back up before 3 PM - amazing. The project also came in squarely within her estimate range at a very fair price, especially for short-notice work. The little things also really mattered - they send text updates when they are en route, when the service is active and complete, and also sent pictures with the invoice via email of the repair before and after the work. It was refreshing to have all of this customer-facing communication. Overall the customer service experience on top of the actual high-quality plumbing service was fantastic. The fact that they are local and woman-owned is also a great bonus.
A major leak at my commercial building. These ladies got me right into the schedule and took care of it all. From my first call to completion it was less than 5 hours. Communication was so great. I knew when they were coming, received a call about the task at hand and what the cost would be then the work was done. The day could have gone completely different for me and my tenant but it all went so smooth. I will continue to support this small Humboldt County women owned business.
Gas leaks and repairs questions
Leave the building, do not switch anything electrical on or off, and do not use a phone inside. Once you are outside, call the gas utility first. They will make the site safe. Then call us for the repair.
We isolate the gas system and put it under pressure to see whether it holds. If it does not, the system has a leak, and the rate of loss helps narrow down where to look before anything is opened up.
Yes. New gas line runs and gas line repairs are permit work and get inspected. Pulling the permit and meeting the inspector is part of the price we quote you.
Yes, that is common work. What matters is whether the existing supply can carry the extra appliance, which we check rather than assume before quoting.
Tankless units draw far more gas at once than a tank does, so the existing line frequently cannot supply them. It is one of the main reasons a tankless install costs more than the unit alone suggests.
Call and tell us what you have. Propane is common outside the city limits here and changes some of the specification, so it is worth saying up front when you book.
