Principled Plumbing Inc

I had an absolutely outstanding experience with Principled Plumbing. From start to finish, the owner/operator Keeth made the entire process of installing our brand‑new water heater incredibly easy and stress‑free. He came out on very short notice—the day after Christmas, no less—and still treated our situation like a top priority. What really stood out was how clearly he communicated every step of the job. Keeth took the time to explain what he was doing, why it mattered, and how it would benefit us long‑term. That level of transparency and care is rare and deeply appreciated. Professional, knowledgeable, and genuinely committed to doing right by his customers—Keeth and Principled Plumbing have absolutely earned our trust. We’ll be calling them for any future plumbing needs without hesit

I want to give a BIG SHOUT OUT to Principled Plumbing Inc. Late Tuesday night I had a broken pipe and spigot, water was shooting up in the air. I got on Facebook and asked the Alta Sierra community page if anyone knew of a licensed plumber, I got several references. But one stood out from them all and made contact, that was Principled Plumbing Inc. The owner Keeth was very quick to respond to my needs and was very prompt. He had the issue fixed quickly and professionally. I highly recommend Principled Plumbing Inc/Keeth to anyone who needs prompt service and is highly knowledgeable in his field. Thank you again Keeth, for your honesty and prompt attention and for going out of your way. I greatly appreciate it. I highly, highly recommend Keeth. His pricing was fair as well. I will be

The team that installed my propane, gas stove were very professional, clean and thorough. They double checked that everything was working before they left. Jake, the More experienced Plumber of the two, was very patient with his coworker, teaching him as they went along. Keith, the owner, provided excellent customer service and was very flexible when I had to make some changes in the schedule. I highly recommend the company!

We were in need of a plumber for our newly built cottage and quickly realized how difficult it was to find someone professional, licensed, and punctual in the Grass Valley area. After reaching out to several companies, we finally found Keith and his crew, and what a relief that was! From the very beginning, they stood out for their professionalism and communication. They showed up exactly when they said they would, were courteous, respectful, and very knowledgeable. Keith took the time to go over every detail with us and even offered thoughtful suggestions for fixture choices and layout improvements that made a big difference. The team handled everything — installing all toilets, sinks, running the entire plumbing system, setting up the water heater, and installing gas lines. Every step

This is my second shout out to Keith and Principled Plumbing! Keith came out last month to save the day with our shower drain leak... Well, just our luck, we discovered another issue just this past weekend. We caught this leak quick, but had to shut off the water to the house until we could get our shower handle/valve replaced. This was on a Friday night... So early Saturday morning I don't hesitate to call Keith. He responded immediately and I explained our issue. It was pouring rain, and the weekend. Keith said he had everything we needed and headed over in less than an hour! Sure enough, he professionally repaired our shower cartridge and once again saved the day! We were able to turn the water back on and enjoy the rest of our weekend. Thanks again Keith. We can't say enough abou
