Nate was so nice, him and his workers did such a good job on my bathtub in my guest house.
We recently had Nate, the owner of Principled Plumbing, come out to our home to fix a minor sink plumbing issue that a previous contractor had completely missed—and we couldn’t be more impressed.
Nate was honest, straightforward, and clearly takes pride in his work and customer service. He quickly identified and fixed the problem, explaining everything in a way that was easy to understand.
What really stood out was that he also provided us with a quote to replace the plumbing in our manufactured home, and there was absolutely no pressure to move forward. It’s rare to find someone who is both knowledgeable and genuinely respectful of your time and decisions.
If you’re looking for a plumber who is trustworthy, professional, and truly customer-focused, we highly recommend Nate at Principled Plumbing!

Nate, Justus and his team are the best. Great customer service, really knowledgeable, and performs the job right. They go above and beyond to meet the customer’s expectations. They never asked or bugged me for reviews or rate like other companies that I dealt with.
Principal plumbing came right out and figured out what the problem was and got me all fixed up in a very short amount of time and a great Price.⭐️⭐️⭐️⭐️⭐️
Nate, the owner was great. He was responsive and easy to get ahold of. Communication was great. As soon as I scheduled my appointment, I received email confirmation. Nate also sent a text reminder the day before the appointment which I appreciate. Justus from Principled Plumbing installed 3 new shower systems in each of my bathrooms. He did a wonderful job. He was punctual and was very pleasant to work with. The job took all day and Justus maintained a positive attitude throughout. He was very professional, knowledgeable and so helpful. I love my new shower system. What an upgrade to my shower. I definitely recommend Principled Plumbing for all your plumbing needs.
Nate and all of the team were awesome.
Great communication- goes above and beyond to make the customer happy.

These guys are amazing! Helped me get my plumbing issue fixed quick and did a great job👌
Really good Communication, Loved working with them! Fast and efficient!
I went to George Morlan Plumbing to see about buying a recirculation pump. I found that for me to install it I would have to purchase tools that would be in excess of how much a plumber would charge me to install it. I was encouraged to call Principled Plumbing for an estimate. I called and got a text from Nate, the owner, who said they could come out the next day to look at the job. One of his employees, Justus, arrived the next day as scheduled to look at the job and gave me a very reasonable estimate. He arrived the next day on time with George, another employee, to install everything. Both were extremely courteous and professional. I couldn't be happier with the quality of their work and the quick response to my job.
Nate and justus are great! I have worked with them on multiple projects and have always got professional results within timing, price and quality. I highly recommend principled plumbing!
Nate was really kind on the phone and Justus was efficient in completing the work. Justus was very thoughtful and helped educate me on each part of the process. Justus worked quickly and cleared our drain in under an hour despite the challenges of an older plumbing system.
Plumbing issues are never pleasant, Nate and Justus made it a bit easier being timely, kind, and honest.
Flat rates for most projects. Declogging is hourly though!
