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.
Water heater questions
On the coast, 8 to 12 years for a tank is normal, and hard water or a neglected anode rod pulls that number down. If yours is past 10 and needs a second repair, replacing it is usually the cheaper path.
Age and what has failed. A thermocouple or a thermostat on a five year old tank is worth fixing. A leaking tank is not repairable at all, and a second significant repair on a unit past ten years is money better put toward a replacement.
Sometimes. Incoming water on the coast runs cold most of the year, which lowers the flow a tankless unit can deliver at temperature, and many installs need a gas line or venting upgrade. We size on your actual fixture count and your coldest month before recommending one.
We keep common sizes moving, but the exact unit depends on what your house needs. If we have to source it, replacements are usually next day rather than same day.
Yes. Removal and disposal of the old unit is part of a replacement, not a line item you find out about afterwards.
Yes. Water heater replacement is permit work, and pulling the permit and meeting the inspector is included in the price we quote you.
