Extremely pleased with the pleasant experience of working with Nancys Plumbing from booking, corresponding and updates, to the quality and care of the work, couldnt be happier! We had a leaky master bath faucet that needed to be replaced. Field techs did an amazing job, they were courteous and patient - everyone in the organization was very pleasant to work with from the office staff to the field techs, we found a trusted plumbing company with whom I would be very happy to do business in the future.

Got my 3 sinks and disposal done in less than 3 hr with Ricardo and Marlon. Very thorough and professional installations, including taking care of frozen connections which would have made me crazy if I had done this work. They supplied a high quality Insinkerator and sink stopper assemblies that I didnt have to order or shop for. More $$ than I expected but I havent had this much plumbing done for a while. Quality work, on time, good cleanup and leak testing. I will use Nancys Plumbing again. Btw, its Nancy the owner who answers the phone!

We had a leak in the wall of our garage. Nancys plumbing came out right away and did all the work the next day. Chris was our tech. He was really kind and explained everything to us. He also talked us through all of our options before we decided on what to do. He cleaned up everything and left the area all put back together. They also have a great text service keeping you up to date with arrivals and work completed. Invoice and payment also. I highly recommend this local service!

I am very pleased with the bathroom faucet replacement done by Nancys Plumbing. I had a faucet that was dripping in the basin. It was a faucet from the original build in 1991 and needed to be replaced. Their customer service was excellent from the beginning, speaking directly with Nancy to scheduling an appt., then working with the tech Ricardo (Ricky) who is very polite and knowledgeable, to the finish of the job. The response time, scheduling, free estimate and completion all done within the same day. Thank you! I will use Nancys Plumbing again!

I highly recommend calling Nancy's Plumbing in Antioch if you need a plumber's help. An old outside spigot on my patio began leaking water at a fast rate, and I wasn't able to turn it off. Nancy's sent their young man Riccardo out within a half hour of my call. He provided excellent customer service and care. He was able to drive to Lowes right away and purchase a new modern spigot, and install it. I was so relieved to have the repair done so I wouldn't worry all night about the huge volume of water that was being wasted!

I cant speak much to the value because Ive only used Nancys but they are always responsive, on time, professional, and do excellent work. Marlin was fantastic when he came out the first time. Christian was attentive, listening to the problems we were having and quickly fixed the problem with minimal interruption to our water use. I will call them again the next time an issue arises.

I woke up to a puddle of water under my sink and a dripping faucet. I called Nancys Plumbing and they had an available service person that same day. Ricardo called me back promptly and came to my house in less than 30 minutes. A real pro, he had the faucet off in no time flat. I highly recommend this company and I will be using them the next time I have any plumbing needs. I could not be happier with the service.

I had called a different company before calling Nancy but because of the unprofessional and no show from the Mattson people I called Nancy and Im so glad I did. They came and did a great job without having to do any digging. Thanks for working with us at the farm we look forward to having you work with us again in the future.

Toilet shut off valve stared leaking and I wanted a new toilet installed too. I contacted Nancys Plumbing this morning at around 7:30 through their online booking. Within two hours I got a text to schedule an appointment. They came to inspect and install a new toilet and shut off valve same day! New toilet looks great!

Our water heater died early in the morning and I contacted Nancys Plumbing after searching for a local plumber. I was able to see the pricing on their website and was quoted the same and they were able to replace the water heater by mid day. The on-site person (Chris) was very professional and answered a multitude of questions I had while continuing to work on replacing the water heater. I will definitely use this business again when changing out my toilets in the next few months and any other work that arises.

Valve went bad on a tub enclosure and had to shut it down at the main. Called Nancy's Plumbing and explained that I had no water until the valve could be replaced. Chris and his brother arrived within 20 minutes and replaced the entire valve and diverter with modern plumbing. Fast, courteous, professional service. Highly recommend, thank you.

For someone who knows absolutely nothing about plumbing I wasnt sure what to expect for my kitchen sink leak. From the time of call to the end of service, it took less than 3 hrs. The customer service over the phone and in person was excellent. They use a house call home texting app that was very helpful, it alerted me when Chris was on his way, when the job began and ended with a price breakdown and total. Chris was on time, very respectful, knowledgeable and quick! The price seemed fair for the job and I am beyond satisfied with Nancy's Plumbing services. Next time I need plumbing services I'll definitely be giving them a call.
