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.

The business is well organized and well run. Nancy responds promptly from the first call to the completion of the job. Christ goes on the appointment punctuated as scheduled, and patiently explained any issues he saw and recommended solutions responsibly. Of course, they charged the best price among about 10 plumbers in the area I called.

It was a Saturday afternoon and our shower value began to leak heavily after attempting a diy repair. We had to shut the water off to the whole house. After calling about 6 or 7 different companies, Nancys was the fist to confirm a technician was available and ready to be sent out. Chris showed up right on time and was extremely polite and professional. He confirmed the problem was the valve, then went to pick up the necessary parts, then came right back and completed the job with no wasted time. Water to the building was fully restored. I would hire Nancys plumbing again and highly recommend them. Great service. The phone representative was great also. Great customer service. Thank you guys again. You saved our day.

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.

Last week I had Nacy's plumbing come by and repair 2 outdoor hose bibbs (faucets) and they did a great job. Not only was it quality work, but it was also great service all around. They provided me with a detailed estimate based on the variation of complexities that could come up once the work started. In the end, the job was simple and they were done in 15 minutes.
I'm very satisfied with the end result! I will definitely use them for future needs!

I called Nancys plumbing because I was driving behind a cool truck on the freeway on my way home to Brentwood. They were able to schedule me for two days later, and the representative was honest and very thorough as he was trying to deal with my long list of plumbing concerns for my new old home. Their estimate for my outdoor faucet repair was actually less than previous estimates Id received from the bigger companies, and the technician/plumber was very candid about my options and ways to reduce costs. I am going with him for this repair because I appreciate his honesty. Chris was awesome!

Nancys plumbing responded quickly to my voicemail request for a whole-house water filter installation.
Their plumbing technician, Marlon, was very willing to install the G. E. cartridge system that I had purchased through a local hardware distributor. He discussed several options and designed a method that would work with our water supply connection and narrow wall face.
The installation date was scheduled for less than three days from the estimate.
The job was completed within four hours, and included a bypass valve system and the workmanship is excellent.
The price was very reasonable and I would recommend this company to anyone looking for plumbing assistance.

Thanks Nancy's Plumbing. I will be using you from now on! I'm a landlord and my tenants called me to report the smell of sewer gasses! Yuck! Nancy's plumbing came out within the hour! FANTASTIC! Christian did an inspection and texted me the pictures. He came up with a game plan and executed it. Fair prices, excellent service, speaks English, and...
I WOULD DEFINITELY RECOMMEND THEM!!

Arrived 30 min after an emergency call on a Saturday. Chris was professional and very clean in his work. Exceptional detail without needing to remove any additional Sheetrock
After a short time, the line was holding pressure and they were complete.
Reasonable and fair rates, excellent response and service.

Chris and an apprentice came on time and repaired the vanity valves and shower controls with much efficiency and professionalism. The finished in less than 30 minutes. Everything works perfectly. I wished I had called them sooner rather than putting up with this for several weeks. Highly recommend them for any repair or service.

Seriously the best experience ever! I was so stressed about having to call a plumber. They were early. Nancy gave me a heads up call. She fit me in for an appt to accomodate me. The guys were very thorough. They were super nice and professional. They even put down floor coverings to keep my floor clean while they worked. Very informative. Will use forever and ever ! Thank you so much for everything. They also use super cool equipment
