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.

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.

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.

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.

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!!!

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.

I would highly recommend Nixco Plumbing. Ask for Audie Reed next time you need service. 🙂

We are beyond thrilled with our experiences with Nixco plumbing. We recently moved into an older home and they have been knowledgable and helpful. They never try to upsell and they ensure we get exactly what we pay for. I love that I can request appointments online and we have never had to wait more than 48 hours for someone to come out (typically less)! Thank you!

My original 10-year old sump pump got water in the case and shorted it out. Called Nico in the morning and two technicians, Nathan and John, arrived that afternoon. The troubleshooting, removal of old pump, and installation of the new one took about one hour. Great same day service. The guys were courteous and competent. They are highly recommended.
