Someone had dumped grease and oil down our large sink. Worse, they clogged it and did not let us know. When I found out about this, I contacted Nixco Plumbing, who came out the next day. Chris took care of the clog, cleaned/flushed the pipe and provided something to breakdown the grease. Our large sink is working perfectly and clog-free. I would recommend Nixco Plumbing for any plumbing issue!
Friendly, knowledgeable, on time! Would highly recommend Todd!
Audi Reed was very helpful!
Audie was great ! He was efficient, diagnosed the issue, figured out a solution and fixed the problem. It wasn’t an easy fix but he did it ! Highly recommend. We’re new to the area and will be using Audie and nixco in the future for our plumbing needs. Thank you !
We were extremely pleased with Audie Reed who evaluated the status of put existing Hot Water heater. He explained the options we had concerning either a repair or replacement of the unit. He then whet about his business doing a replacement. His work was of the highest quality. I will recommend him to all my friends.
Audie came first to our house for an emergency where he was quick, efficient, clean and very helpful and polite. We would call and use him again and again for all our plumbing needs. Highly recommend!
Shawn Crank was my plumber today and he was very friendly and informative when explaining the cause of my plumbing issues. He explained several ways to solve my issue along with the pros and cons of each. I am very appreciative of his time and experience to help me resolve my issue.
Lost important plumbing, these folks had someone out in a few hours. Fixed everything. In today's world it seems like a fair price. Either way highly recommended
John and Alex did an amazing job and are very efficient and got us up in running in no time !! Highly recommend!!!!
Finally found someone to solve a problem plaguing us for months with a very simple diagnosis and solution. Update 2/5/26 Had them replace broken garbage disposal. Quick Availability, on time, and quality work
Incredible service Nathan, Alex and Paddy!! We had a floor drain issue where the pitch was not correct (from settling) from the floor drain going out to the main drain out of the house. We spoke with at least a dozen different plumbers and drain “experts” and everyone told us different stories on how to resolve the issue. I called Warren County building permits inspections and they recommended NixCo. Nathan came out to inspect our problem and immediately had a plan on how to fix the issue. Out of all the plumbers I spoke to, his knowledge and recommendation was the one I felt the most comfortable with. We needed about 25 ft (picture below was about 15 ft of repair) of foundation that needed to be jackhammered, new PVC with proper fall and concrete put back. Nathan, Alex and Paddy were always on time, very professional/polite and kept me posted on everything and always happy to answer any questions. Great price, great customer service! I would highly recommend and use NixCo.
Our drains we backing up. I called at 4pm and was able to get someone out next day at 8am. They sent Audie and he did a great job. Made sure everything was working and explained what happened and how to keep it from happening again. Great service! Thank you Audie
Just had Kris and Mason come out to look at our softener and test our hardness. Had a great experience with them both and appreciate their hard work and efforts. Having them put in a new water softener in sometime soon, can’t wait for more excellent service!
Kyle and Paddy did a great job fixing our sink drains and replacing our expansion tank. Thanks guys!!
Sewer line repair waterline I had no water sewer l in would not flow
We had an issue with our drain that was causing a leak when our washing machine was on. From the staff member that initially took my call to Shawn who came out and was so patient and kind and solved the problem ( and an extra one) , the entire process was actually pleasant. We have had many plumbers throughout the years and Nixco is definitely my favorite! They even called the day after to make sure I was happy with the work! Very class act operation and I will definitely be calling them again with if any other plumbing issues come up. Thank you Nixco!!
Audie and his assistant Kyle were excellent. Very professional and friendly. I had 3 toliets. I would highly recommend them and hope they can come when I ne4d them again.
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!!
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.
Audie and John did a fantastic job fixing our water heater. Quick, professional, and great guys.
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.
Chris McClure was professional, on-time, explained everything that needed to be repaired or replaced. Fantastic experience, highly recommend NixCo Plumbing.
I had a few pluming jobs and needed a professional. I have used Nixco in the past and didn’t hesitate to call when this need arose. I was able to get a fast appointment, confirmation emails and a text to alert me of their ETA. Chris Mc arrived on schedule and wore protective footwear to protect my floors. He went from task to task providing options and quotes before work began - it turns out I didn’t need as extensive repairs as I thought and saved some $$. The completed work was perfect and the space left clean. I have no regrets engaging Nixco and can highly recommend them for projects large and small.
On time, knowledgeable, gave me a great feeling for NixCo.
I noticed my dump pump wasn’t working after looking at it I couldn’t find the issue. Called Nixco and the quickly scheduled an appointment for the next morning. Audie gave an ETA and arrived on time! He was very personable, knowledgeable and did his homework on our last repairs. He assessed the issue and much to our surprise, it was just the control panel in the battery back-up. No need for a new sump, only the battery & control panel. He also checked our hot water tank and noticed the expansion tank was faulty. Thanks Nico for being honest and forthcoming…it saved us money & prevented emergency situations. Being a NIXCO CBustomer is well worth it!!!
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.
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. 🙂
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!
John Krusling was very personable and extremely helpful today with our fix. We had water leaking from upstairs into our new kitchen. John was able to diagnose the problem in a matter of minutes. He completed the job in just a few hours when I thought it would’ve taken into the next day. Great experience and will definitely be calling again. Highly recommend John to anyone in need of future repairs.
Had a difficult kitchen faucet replacement. Nixco was timely with the fix and the Nathan did great work
I was informed when Nathan was to arrive, that he was running late and he could still come that afternoon or in the morning, and that he had arrived. He was knowledgeable, professional and personable. Even though it was late he answered my many questions. I did not feel that he was rushing to finish. He assessed the problem, explained the repair and gave me a price to fix it. He replaced a faulty valve and examined the leak from our dishwasher and made suggestions. I think prices could be lower but I feel confident in the work done. I am pleased with the Nixco service and will use them again.
Our 99 year old home had a significant problem with a back up of sewer pipes due to tree roots. Nixco scheduled our service quickly, and Audie was thoughtful in finding the problem and the best solution. Audie and Paddy did an excellent job and were great about communicating what needed to be done and were up front about the cost of the work. We are confident that they have solved our problem. We appreciated their professionalism and hard work. We would highly recommend Nixco.
