Recommended Customer Reviews

Friendly, professional, practical, smart, honest. Needed my shower fixed, and was able to get ahold of Nathan right away even during the holiday season. Got me scheduled without any hassle. Available for questions. Prices are fair, great service, gives you that peace of mind, pleased overall.

Was looking for plumber and call Nathan based on his 5 star reviews. He was very professional over the phone, and I decided to book an appointment for next day. To my surprise he show up the same day, to fix my drainage issue. It was relatively small job, but I found Nathan very willing to explain the minute details for my benefit...which I was very much appreciative of...too many times in past I have found contractors irritated by questions by the owner (me)...it was nice to find someone who did not mind, and in fact welcome sharing his knowledge.
I would definitely recommend Nathan to family and friends...quick response at a reasonable price...I am planning to schedule Nathan for maintenance on my tankless water heater!

Today, my kids and I woke up to a leaking faucet. Determined to fix it myself, I made several trips to Home Depot but found myself struggling to remove the hardware. I reached out to Plumbing 101 and spoke with Nathan, who immediately put my concerns at ease. Nathan went above and beyond--he kindly FaceTimed me and patiently walked me through the repair step by step.
What truly stood out was his dedication and genuine care. Nathan consistently followed up with me throughout the day to check on my progress and offer further guidance. I was amazed at his encouragement, his belief in me to successfully complete the repair, and most of all, his integrity. Instead of trying to push a service for profit, he focused on empowering and assisting me.
If you're looking for a plumbing company that values its clients, eases the stress of repairs, and offers cost-effective solutions, I highly recommend Plumbing 101. Their professionalism, support, and compassion are unmatched.
Thank you so much, Plumbing 101, and a special thank you to Nathan! We now have running water, and I couldn't be more grateful!

These guys were great!! Called on SUN and they came promptly the next day. Fixed my leak, explained the issue, reasonably priced, and did a great job!

Nathan and his team know what they are doing. Nathan communicates quickly very well via texts and phone and during his work he makes sure you understand what he is doing. I hired him for a shower installation and to fix some of the piping in my walls that are switched from hot and cold. He made sure to leave the bathroom clean and finish the work in good quality. I absolutely would hire him again for a future project.
My only suggestion is to have him write the quotes down or text the amount for you because I had another project for him but I didn't understand that the quote was a total amount for everything versus I thought it was an extra amount on top of everything and if I only knew it was the total I would have hired him for that project too!

Absolutely the best team of plumbers I have ever had to my home. Great work, very professional and fair price.

Nathan the owner is very
Professional and has the integrity I need these days from businesses. Own your work and that's exactly what he does. He's worked on a couple of plumbing issues for me and he's done nothing but outstanding work for me. I HIGHLY RECOMMEND HIM!

We cannot applaud the integrity of this business enough! From answering the phone, possessing the knowledge about the craft, answering questions, offering options, showing up on time, along with contacting us regarding arrival time, we are so very pleased! This is the third plumber we have used within a year and we will look no further. So very accommodating and filled with customer service.

Another great SHOUT OUT to Nathan 101 plumbing!! Installed non-existing waterline for a new fridge. Excellent & professional work/service, very fair pricing as well. He has helped me for the past few years, HIGHLY Recommend & will ONLY call for any plumbing related work. Thanks to his wife Elizabeth as well for scheduling.

Nathan of Plumbing 101 has been our family plumber and repipe contractor for many years, since before he owned his own business. Nathan is honest, beyond fair, trustworthy, kind, helpful and good at checking out all sinks, showers, faucets and toilets for any little issue before it becomes a big problem. He never over sells and is not pushy at all. I strongly recommend you call Nathan for any plumbing issue from little to overwhelming.
