Trusted Slab Leak Repair & Detection Services in the Greater Cincinnati & Mason, OH Areas

Nathan was professional, efficient and explained everything so I knew what the root cause was. I additionally appreciated the short notice response. Great service overall. Thank you!

Our experience with Nixco was (and always is) incredible-I would recommend them to anyone

Clogged drains. Frozen pipes. Old house! In a world where many jobs are completed when "it's good enough", that is not the case with Nixco! If it isn't right to their expert high standards...they work until it is! Jared goes way beyond "good enough" AND is friendly, skilled, and obviously knowledgeable. Thank you Jared. Thank you John. Thank you NIXCO!

We had Chris McClure from Nixco Plumbing onsite for our annual backflow system inspection, and once again he provided excellent service. Chris is extremely knowledgeable, thorough, and professional, ensuring everything was inspected properly and clearly explained. He is consistently reliable, respectful of our facility, and mindful of our operational needs. Chris is our preferred technician, and for good reason—he always takes great care of our needs and makes the entire process smooth and stress-free. We truly appreciate his attention to detail and dependable service, and we highly recommend both Chris and Nixco Plumbing.

Chris McClure always goes above and beyond to fix whatever plumbing problem you have. Great at troubleshooting until he gets to the root cause. Chris is respectful of your property and cleans up everything when he's done. Very happy that I have him for a plumber.

Todd and Mason were very friendly and professional came in to my home and replaced my water heater in a very short period of time so I could get back to having hot water again!!

After hours emergency frozen water pipe breach Immediate and timely response Plumber was courteous and efficient in handling the repair

I have utilized Nixco since I moved here 8 years ago. I had 2 issues today..a sink not draining and a toilet seat that broke!! I called yesterday and Mary was friendly and quickly scheduled me for today. Chris came out on time and was efficient, friendly and very professional He quickly resolved both problems.Nixco is my “ go too” for all my plumbing needs. They are a local family owned company that has always done a great job for me💕

I definitely recommend Nixco for all of your plumbing needs. I’ve used Nixco to install a water heater, modify the plumbing to my refrigerator water filtration system, and most recently they fixed a problem with water backing into my dishwasher. Todd and Paddy did a great job fixing the water backup issue I have been experiencing most recently. They quickly diagnosed the problem and fixed it without overselling beyond what was necessary to correct the problem. This kept the price down. In 2018, Todd also installed my water heater. He fitted it with a tub under the water heater and a pcv pipe to the basement drain. I’ve never had a problem with the water I’ve been using Nixco for 15 to 20 years. I started with Nixco with my previous house and continued after moving into a condo. They are trustworthy, reliable, and they don’t oversell.

Audie is a professional. Appreciate his time and expertise.

Every service call we’ve had with NixCo Plumbing has been extremely professional. Called on Tuesday, Mason W and Kris B were out on Wednesday to provide estimates for what we thought was a serious water pressure issue raised by our RO water company. They tested and explained why their finding wasn’t as serious as we were told. There are items we have to discuss with our HOA before making any repairs/adding a pressure valve but I am extremely confident that NixCo will do a great job. There were a few other items we wanted estimates for (two leaky faucets, bathroom remodel/shut off valves needed and corrosion on water main). Mason and Kris checked those items out, explained what the work involved would require, then gave estimates for those as well. Very appreciative of their time and professionalism.

Audie and John did a fantastic job fixing our water heater. Quick, professional, and great guys.

Todd did an excellent job not only did he and his crew install a new gasoline, but when our hot water stopped working he was very responsive and helped fix our issue quickly! Couldn’t be more happy with the service we received from everyone at Nixco!

Had a faulty water heater that needed replaced. I definitely was not happy that I had to replace a water heater, but oh the joys of home ownership. I was fortunate to get ahold of NixCo (I used to work with Neyer, but NixCo and Neyer seemed to have merged) and that they happened to have an appointment available that day (that was a miracle!). Kris B. was my service technician and Mason W. was his helper. Both were friendly, polite, patient, and well trained (Kris was doing a a great job coaching Mason). Kris and Mason made it a pleasant experience. They were conscientious of not making a mess and told me what I needed to know, and answered all of my questions. They installed a Bradford White ICON System that comes with a 10 year warranty. They started at 2 PM and wrapped up just before 4 PM. I'm glad to be able to have hot water. I would definitely ask for both of them back and this experience with NixCo seems consistent with my prior experiences with Neyer.

This was our third use of Nixco for plumbing problems. Today Jared and John came to work on our dead water heater. Just as with the other two visits the guys were knowledgeable, skilled, and courteous. It's good to have plumbers you can trust. We send all of our friends to Nixco with confidence.

Jared and his assistant (sorry forgot his name) were prompt, polite, professional, and answered all my questions! I was given options to fix my plumbing issue, a first! I will request Jared again if possible!

Chris and Alex came out to update my sewage pump. I bought the pump and they did a great job installing it, including a new plastic 8-bolt cover. Chris worked extra hard to get the sump sealed for both water and gas leaks. They wanted to use a different check valve, but I wanted to keep my specialty one for quiet operation. Honestly didn't see a need for a different check valve as mine was 2 months old, so they agreed and used mine. Great guys to work with. They are sensible and knowledgeable.

Shawn was quick to inform of the problem, to tell me the cost. Pleasant and knowledgeable.

Very responsive to the first call, on time and quick resolution. Very satisfied

Chris McClure was professional, on-time, explained everything that needed to be repaired or replaced. Fantastic experience, highly recommend NixCo Plumbing.

Good experience from initial contact through installation. Scheduling appointment was easy, and I appreciated the reminders for the appointment and the notice when the technicians were on the way. Nathan and Mason did an outstanding job with the installs; efficient, clean, great quality. I appreciated their expertise, answering questions thoroughly, and very personable.

Nixco was able to send someone out within a hour of calling for service. Shawn did a great job explaining why my sewer line backed up a second time in just a couple of months. He was able to clear the clog and gave me recommendations for keeping that line clear. I am very satisfied with the service provided and will definitely use Nixco again.

Shawn is great. He explains things well and treated us fairly!

We had an “emergency” situation on Sunday and the on-call technician (who had to travel many miles) was here within 2 hours. Not only was he very knowledgeable and professional, but he was also very friendly and willing to answer all my questions. He got the job done quickly and efficiently. I would highly recommend Nixco Plumbing. Ask for Audie Reed next time you need service. 🙂

Chris McClure was our technician. He is super friendly, knowledgeable and efficient. He was able to take care of multiple issues we had all in one visit. He was a pleasure to work with.

Fixed original problem and identified others needing work. Stayed late and completed all

Audie did a great job fixing my pressure valve and other plumbing issues, smoothly and professionally.

Todd Reed has always done a wonderful job on my projects and repairs

We had our Rinnai tankless water heater replaced. John and Alex did an amazing job 👏 on this installation and was completely done in the estimated time we were given in the estimate. Thanks again guys.

Both Nathan and Mason of NixCo Plumbing did a great job with replacing my 75 gallon gas water heater and a water pressure valve. Was having problems with the water pressure and that was resolved. The guys did a great job with a quick installation so we could get the water back running and an excellent cleanup job. Very friendly and competent.

Installation on short notice was greatly appreciated.

Kyle was fantastic to work with. Did a great job, was very efficient and was here within 10 minutes of calling for repairs! Nixco is always honest about what the options are and what the best recommended option for the customer is.

Audie and John did a great job replacing our main shutoff and water softener. Nixco is a bit more expensive, but they are my go-to in no-water situations. Thanks!

Kyle Cox did an excellent job. Very happy. He was very professional, polite, and honest. No surprises. Would highly recommend.

Kyle Cox did an excellent job! Very honest and thorough. No surprises. Very happy with today's job done by Kyle and Nixco and would highly recomend.

Punctual, courteous, and competent- what else do you want, eh?

Shawn was so supportive and helpful over the weekend to get me set up for new hot water heater early in the week. John and Alex were wonderful and efficient with the new installation am I am thrilled to be heading into a hot shower!

Fantastic service!!

Shawn Crank from Nixco arrived and quickly evaluated the drainage problem in our basement. He explained everything, explained options, explained what he was going to do and why and presented a fair price. When complete he cleaned up the area, tested for flow, leaks, water pressure, etc... ALWAYS GO WITH NIXCO!!!

Used Nixco to repair a damaged underground water supply line. John and Alex were great, helping all along the way to diagnose, locate, and then ultimately fix.

I’m just starting to work with them but I’m so glad I found them. They were very knowledgeable and courteous. I wouldn’t work with anyone else going forward. They contacted all the correct people. A+

Shawn came on time and resolved the situation quickly and completed the repair efficiently.

Excellent service from start to finish! John showed up on time, did a great job, and was easy to work with.

I’ve always had a great experience with Nixco. Audie and John replaced my water heater today. Very friendly and very knowledgeable.

Shout out to Nathan. Good job on fixing my gas leak

Shawn did a great job. He was quick to access the issue and professional and efficient in fixing the problem. He kept a high degree of courtesy and friendliness throughout the process.

Mr Todd Reed was very professional, knowledgeable and fixed my main line. Never been so happy to do my laundry and dishes, lol. Wonderfull customer service and very nice. Will call for Mr. Reed in the future.

Nathan with Nixco Plumbing worked out a complex situation with my shower valve. He was very professional and solved a problem others were not able to. My "hats off" to Nathan and Nixco Plumbing.
