Owen W
Service: Navien tankless water heater installation

"Had a Navien tankless water heater installed by Predictable Plumbing and couldn't be happier with the experience. The plumber was professional, knowledgeable, and clearly knew the system inside and out. Everything was set up the right way—from gas pressure calibration to venting—and he took the time to explain how to use and maintain the unit. The installation was clean, efficient, and done right the first time."

Jason E
Service: Navien tankless installation – next-day service
"Jack at Predictable Plumbing is awesome. Very professional & knowledgeable and was able to install a new Navien tankless water heater the next day. I highly recommend Jack for your plumbing needs!"

Claire P
Service: Navien boiler service – 45-minute response
"Jack was super helpful. I'm a new homeowner so he walked me through the Navien boiler system to ensure confidence. He answered the phone quickly and was able to service the boiler within 45 minutes of me calling. Great service, would recommend!"

Tom B
Service: Navien NHB-080 Combi boiler parts
"Jack performed admirably and went far above the norm in customer service in assisting us in obtaining Navien parts for my 2017 Navien NHB-080 Combi boiler/water heater."

Service: Water heater installation
"Predictable Plumbing did a wonderful job installing a water heater at our home in Monticello!! Highly recommend."

TJ W
Service: Emergency water heater replacement
"Our water heater failed and was leaking. Predictable Plumbing was able to schedule immediate service. Plumber Jack was professional, friendly and did an excellent job replacing the water heater with a topline product. He also did a new installation of water supply to our new refrigerator while on site. They are our preferred plumbers from now on."

Reviews About Honest Service & No Upselling

Customers consistently highlight Predictable Plumbing's transparent pricing and willingness to recommend the most cost-effective solution—even when it means less work.

Anab A
Service: Sump pump troubleshooting – free phone support
"I had an emergency recently when my sump pump suddenly started spewing out water—it was overwhelming, to say the least. I reached out to Predictable Plumbing, expecting the usual runaround or pressure to book an urgent (and expensive) service call. But what I got instead was something rare: genuine honesty and real help. From the very beginning, the plumber kept it honest with me. He didn't try to upsell me or create unnecessary panic. Instead, he calmly and clearly walked me through the issue step-by-step over the phone, helping me troubleshoot it on my own. And here's what really impressed me: even after we resolved the issue, he offered to follow up and check in to make sure everything stayed in good shape. That kind of integrity is hard to find."

Mark P
Service: Valve repair – honest assessment
"Jack told me straight up that the valves were probably still ok even after 30 years, a little tightening job would fix the leak. I appreciated the straight shooting. However, I proceeded to replace them after that amount of time so I won't have to think about them ever again. Jack is professional, honest, efficient and personable. This was my first time using Jack but if I need another service, or plumbing need I will be calling Jack. I have been without a good contact since last good plumber retired."

Josh B
Service: Plumbing assessment – no unnecessary upsells
"Jack was very prompt, thorough in his assessment of our issue, provided a clear explanation of our options, and did not try to sell us services we did not need. We will definitely be calling Predictable for our future plumbing needs."

Bryce S
Service: Water heater anode rod – free phone guidance
"They were very helpful over the phone on a Saturday evening when I decided to check and change the anode rod in my water heater. It seemed like a diy task that was right up my alley but the top of the rod broke off when trying to remove the old rod. I had not even considered that possibility so I had no idea what to do. They walked me through the steps to remedy the situation and I was able to finish the job! I really appreciated their help and would definitely recommend them for their knowledge and no hesitation willingness to help."

Reviews About Quality Work & Expertise

Predictable Plumbing is known for catching issues other plumbers miss and ensuring code-compliant installations.

Chad H
Service: Vanity install, water line, RPZ correction
"A contractor had Jack install a vanity faucet and drain for us as part of a larger home remodeling project. We had him come back to reroute a water line from our utility room to our refrigerator and, while he was working on that, he noticed that an RPZ that another plumber recently installed lacked a necessary air gap and drain line leading from the RPZ's vent to a nearby drain. He got all three projects done quickly and we're very happy with the work! He also provided a number of replacement options for when our old water heater eventually bites the dust."

Valerie E
Service: Faucet repair + gas leak detection
"Jack Mattila was friendly and professional, made me aware of possible gas leak while repairing a leaky faucet in the utility room. Which was confirmed by CenterPoint Energy, who I was able to seal the leak same day. Made homeowner aware of other problematic issues and fixed them providing convenience and safety of mind. Provided additional feedback about unrelated repairs and recommendations of suitable materials to complete inspection requirements."

Eric S
Service: Code compliance consultation
"Jack is an expert at his trade. He goes above and beyond the expectations. He had no problem answering and solving any code related questions and requirements we had on our project. A+ service and communication! Highly recommend."

Amber L
Service: Plumbing repair – correcting prior work
"Great job fixing a poor contractor's plumbing work. Very prompt and easy to work with! Highly recommend Jack!"

Kalie H
Service: Reverse osmosis system installation

Ryan R
Service: Water softener replacement
"Jack was great! I can't recommend anybody higher for plumbing repairs. Jack's communication and quality is first class. He explained everything during the repair clearly and the price was clearly stated with no surprises. He was on time and took great care while working in my house replacing my water softener. I will definitely use again in the future."

Janelle R
Service: Water softener + filter system + toilet
"I had Jack come back to replace a water softener/filter system along with a toilet replacement as he did such a great job previously. He is very knowledgeable and explained how the system(s) work, efficient, affordable and very pleasant to speak with. You have to give him a call for your plumbing needs."

Service: Kitchen sink drain repair – older home
"Fantastic experience. Jack helped fix problems with my kitchen sink drain in my old St. Paul 100 year home. Replaced some DIY plumbing. Showed up on time, easy to schedule, and I knew the price before he began work. 5 stars! Thank you."

Matt Van B
Service: Plumbing diagnosis
"Jack did a great job of identifying our problem, as well as a solution."

Bobby W
Service: Tub spout, valve, and showerhead replacement
"I was fortunate enough to have Jack Mattila work on my tub today. I really enjoyed his expertise, friendliness and professionalism. This young man is top-notch and your company should be very proud that he is employed with you. He explained everything he did....installed everything professionally and perfectly, and I couldn't be happier with the job he performed. He replaced a new spout, a new water controller, and a new showerhead. What was also amazing was he completely cleaned up the area when he was done. Vacuumed up any loose particles....so impressed!"

Nicholas K
Service: Faucet repair
"Had a noisy faucet and reached out to Predictable Plumbing to check it out. Jack quickly diagnosed the issue, explained the fix and cost clearly, and got the job done with the right parts. Very professional, easy to work with, and overall a smooth experience. Highly recommend!"
