The crew did a great job on my home in Napa in the last part of September, October and November of 2025. They will be back to flush my water heater that they installed in September of 2026. I had a total repipe done of whole entire house and a new water heater was installed in my garage. It took a few months for the crew with Eric to get the job done but all my pipes are still working. They had to crawl underneath my house and dig a trench in the front yard to put in the copper pipes and drill through my closet in the bedroom behind the bathroom to put in more copper pipes and they put in new faucets in the bathroom and kitchen and sink in the garage. It took a long time, but I am grateful I have good water pressure though out my 1941 home in Napa. read more

They came out to do an inspection and bid for work we need done on a house we just bought. 99.9% sure they did the cup of water splash scam on me because they showed me a pipe in my garage/basement that had a LOT of water dripping out and a good splash of water on the plastic storage bins and floor below. They said it was coming from my shower, knowing we just bought it and never actually showered here. They were running the lines for a few minutes each to test them all. After they left I ran the shower for 20 minutes and that pipe and area of my house was was bone dry. (I ran the other sinks and shower just to be sure, dry.) Then on top of that we were quoted $8000 for a halo 2 carbon filter which is double or more the real cost ($2500-4000) read more

Gray Plumbing overall was great but thank goodness my drain cleared itself because the tech quoted me $791 to snake my kitchen drain. Once I picked myself off the floor I was doubly glad I didn't need the service!! Somebody has to be cheaper...this is a rip off!! read more

Never requested anything other than replacing the gasket. So you were planing and hoping that I would pay for work I Never requested? Great way to attract customers! Again Never do business with Gray Plumbing. read more

Estimate scam and fraud. Fake reviews We did use them before for toilet repair which was not good, the job needed to be redone. This time we called them to unclog the drain. What can go wrong, right? Wrong! They requested $700 for some bogus repairs. We have refused, then they have declared they will charge credit card on file $120 "for estimate" without our approval. We got the job done with another company for a FRACTION of the price they requested. They have 360 positive reviews on Google Maps. The reviews say "they came to my house...". On Google Maps you can not leave a review unless your location history shows you have been to their office. Fake reviews left by multiple accounts from their office. Never call those guys. Never give them your credit card details. read more

Joined their yearly program, however after they came the first time their prices skyrocketed up ridiculously. I think they are a good company but when you have good clients please don't take advantage of them read more

I found their ad in the Fairfield Our Town magazine. I requested a quote through their website seeing as it was News Year Day. They called promptly the next morning and were able to fit me in within three hours. Brandon came and did a wonderful job on the servicing and explanation of what was going on and different options to attack the problem in this case my tankless water heater I will definitely be using them again because I got my money's worth and I feel it was a very well done job and I would highly recommend them read more

I'm under a lot of stress, sold my home and trying to move when garbage disposal went out. They came out first thing. Brandon Fixed the problem, explaining things along the way. A1 service read more

Gray plumbing did a great job. Brandon, Andrew and Eric worked so hard to ensure that the work they did on our house is great and to our full satisfaction. They are all very professional and hardworking. I will recommend them and the company they represent to use for the plumbing needs anyone need done in their home. Thank you! read more

Gray Plumbing Wanted to charge me $2000.00 for a 1 hour toilet replacement. I even had the new toilet. Don't pay the $125 dispatch fee unless $2,000 an hour is within your budget. read more

I needed a plumber after finding a small water spot on the ceiling, and ultimately chose Gray Plumbing for their positive reviews on Yelp and Google, and Diamond Certification. Devontae was sent over first thing the next morning to investigate the source of the leak. After a thorough assessment, he showed me the exact pipe that was leaking, and carefully explained the repair scenarios and overall repair process. I never felt never pressured choose one over the other. In fact, he provided me a couple different quotes on the spot to allow me to decide what is best for my family. I'm glad I found this company for its knowledge and quality, efficient service. read more

requested a service call for broken toilet and replacement quote. Quote was for over 2k! then I was charged a $125 service fee because I declined the work due to outrageous quote. I called roto-rooter, had toilet removed and new one installed in less than 4 hours for $900! gray plumbing is ridiculous. The service tech was very polite but good grief! read more

I cannot speak more highly of this company. First, they were able to get me an appointment within 2 hours of my call. Next they sent over JEREMY SMITH...nice guy, polite, informative, and a Skilled repairman. The guy made the price alot more digestible, which I will say was pretty high but not outside of the average costs of a plumber. Very refreshing to see a Skilled Trades guy come out with this sort of salesmanshipand professionalism. Gotta appreciate a company that keeps guys like this on staff. IT MEANS THINGS WILL GET DONE RIGHT THE FIRST TIME. They will be my go to plumbers from now on! read more

I called to replace a kitchen faucet in kind. I had exactly the same faucet my husband tore his rotator cuff and could not do it. They charge $125 just to come out which is fine. I was shocked to find out they wanted $900.00 for a simple kitchen faucet exchange! We paid the $125.00 for nothing and sent them packing. When I called to make the appointment I was told they would estimate the work when they got here. Never in a million years did I think this simple thing would be such an exorbitant amount. I feel taken advantage of and there is a lack of transparency when you call. Could they not of quoted the pricing with a video or a picture. The tech Andrew said the pricing was company policy. I do not recommend them. I feel taken advantage of and scammed. How many $125 visits do they do and no real work. read more

Excellent service! Éric was professional, on time, and great in communicating my issue.

Their team is always helpful and they make sure your project is done correctly. Michael was very courteous and respectful. He would wear his booties in the house and made sure I understood the work that needed to be done. They have worked on my son's house also! They may not be the cheapest plumber but they are professional and get the job done and many times you end up getting what you pay for - if you go cheap - you get cheap! They have a quick response time and are always friendly to deal with. read more

Highly recommend Gray Plumbing for reliability, expertise, efficiency, hard work, value and courtesy. Plumbers Eric and Michael were lifesavers before Christmas when I had major plumbing problems. I had contacted an individual plumber who found a pipe problem under my house that was more than he could deal with. I contacted Gray Plumbing and Eric came promptly, identified the problem, explained it and showed photos. Eric and Michael replaced several badly corroded and leaking pipes under the house, keeping me abreast of what they were doing. They laid paper in the house keeping the floors immaculate. They were quiet, polite, and worked quickly. Thank you, Eric and Michael for doing a great job. read more

Had slow drain in master bathroom sink. Easily booked convenient appointment. Eric was on time. He completed check of all plumbing fixtures. Replaced pipes under bathroom sink. Also replaced parts in toilets. Left us a happy home. Thanks Eric. read more

Deontae Frank did a superb job all around. He explained about the company first and asked specific questions to narrow down the exact issues. Once that was done he explained, well, more than any other service person in recent memory. He was thorough, to say the least. I never felt he was rushing through the process. He examined every plumbing feature inside and out, another first. In short, I cannot say enough about how great a job Deontae did. Bravo! read more

Deontae Frank was great to work with. Kind and very knowledgeable about his job. Looking forward to working with him again soon. I've been a customer for 6 years. read more

Jeffrey and Kivon arrived after Public Works turned off the main water line to our home. They inspected the front yard where the water was flowing uncontrollably and advised us what steps will be taken to resolve the issue. They went above and beyond to investigate the copper water pipeline and could not locate the break. During this time they made sure we had running water right away. Kevin (arrived later) and Kivon replaced the waterline with a new copper line and added additional shut off valves (city requirement). This morning the work was inspected by the city inspector and all is good. Who knows how long the copper pipeline was broken. We noticed the water pressure in our downstairs bathroom improved. We are happy homeowners and would highly recommend Jeffrey Gray Plumbing to others in need of plumbing repair. read more

Jeremy came out to replace hoses for garbage disposal. He was honest on was needed to be completed. He was very pleasant, professional and explained every step. read more

Installed new water service pipes from meter to home. Very expensive. Sprinklers wouldn't work after work was completed. Called them and they came out but said it wasn't anything they did even though they didn't check above the meter. Turns out it was their fault and there was a crack and hole in the sprinkler line where they worked. They would not respond to my emails or my phone call so I had the sprinkler fixed. Very disappointing. I would not recommend this company. read more

Outstanding prompt service done right at reasonable prices. Definitely would recommend.

Gray Plumbing gave me a clear understanding of what was going on and what it would take to fix the problem. They were kind curious and timely! read more

These guys were super professional...covered their shoes, wore their masks without me asking, and were careful with everything, including not letting my cat out. They arrived as promised, unpacked the toilet, finished the whole job and then carried away my old toilet and the packing of the new one. I imagine you could pay a few hundred dollars less somewhere else, but I doubt you could get better service, or more professionalism anywhere. And they came the same day I called! Susan S read more

We called Jeffrey Gray Plumbing to come out and fix a wax seal and supply line leak in our toilet base. When he arrived he quoted $524 to do the job. We said that seemed high, and he said it was a "flat fee". This was for our rental property. When I went home I checked my bills for the exact same thing done by Ken Mays Plumbing, and the bill was $200. After he finished he said that he would give us a "senior citizen" discount and reduced the bill by 10%. Watch out for this company. Seems there are many reviews on this same issue. read more

I initially contacted them to get a quote to replace a 1500 gallon grease interceptor. An appointment was made and Jeffrey and his assistant came out to assess the job approximately a week later. He told me he would work on the quote; obtain material and permit prices, contact the Contra Costa County Sanitary District for requirements and e-mail me a bid. I attempted to follow up with him approximately two weeks later by phone and no response. I e-mailed him and still no response. I called again the following week, leaving yet another voice mail and no response again. I made one final attempt by e-mail to contact him and never received a response. I think maybe this guy bit off more than he could chew with saying he could replace the grease interceptor but once he saw the job, couldn't admit it was over his head. Just by the fact he could not man up and admit the job was too much for him to handle, rather ignore my calls and e-mail, I would not recommend him for any plumbing job going forward. The thing is, had he been responsive initially, whether he could do the grease interceptor job or not, he could have had all our plumbing business for an assisted living facility. read more

Fast response, pleasurable to deal with, and fair prices. Jeffrey Gray plumbing was called the morning after a major stoppage incident in my new home. They were able to arrive within 3 hours of the call, and had a quick diagnosis of the issue. Jeffrey and his son dug out the old clean-out near my house and installed a new two way clean-out in the same location. From here, he snaked the line, ran a camera, and ensure the issue was completely resolved. Jeffrey was a punctual, happy guy, who seems to enjoy what he does and explained everything that was happening as I barraged him with questions. read more

They came out for a scheduled appointment on a leaky faucet. We were charged app. $900. We felt they price gouged us because we had to get it fixed immediately and couldn't call another plumber. Their previous visit for a leak in the front of the house was only $150. read more

Was having trouble getting a part off to complete our sink installation n Kevin easily removed it and explained how we could some avoid some other problems down the line too for completing the installation without just saying they needed to be done and charging us. I appreciate an honest company who won't just try to take your money! Thank you so much Jeffrey Gray plumbing! read more

This was a first-time call to Gray's after doing a little web searching for a local plumber. The call was quick and professional and they were able to come out the same day with a scheduled arrival time between 12 and 2 pm. Due to an error on my part, I was not home and received a call at 12:02 that they were at the house, ready to go. I know better than to expect that every time, given the unknowns of any earlier work they may be on, but needless to say it made one heck of a first impression. Michael and "Manny" were thorough, professional, and worked through the challenges of dealing with 40+-year-old kitchen faucet piping, corroded shut-off valves, seized fittings, etc, in 2 adjacent houses. After an inspection, the reasonable price was quoted upfront and that was what it was when it was all said and done. We are back up and running, with 2 new faucets, cleanly installed water lines, and no trace of all the cutting, bending, and other efforts they had to put into making it happen. 100% chance they will be our first call for any work we need moving forward. Thank you Michael, Manny, and Gray Plumbing. read more

It was shocking what Jeffrey Gray wanted to charge for work at my son's house which I manage when he is deployed. Mr. Gray wanted $2,700 to replace a supply hose on one toilet, and to also put a new supply hose on each of the other two toilets to prevent future leaks. I just paid a local plumber $75 to do the same thing to one toilet upstairs. It's really shocking what Mr Gray tried to do to a woman whom I guess he thought wouldn't know any better. I really don't know. I paid him $300 for his ELABORATE estimate with a bunch of pictures which I can never use (could have potentially been useful for insurance but only to the degree of the value of a REPAIR) but I really wanted to find a plumber that I could hire to fix things for future years there in Suisun City. I love to write positive 5 star reviews. I have never, ever given anyone a 1 star before on any web site. read more

Jeffrey is punctual and professional. We've hired him for 2 different jobs at our house and he quickly replied to our requests. He's a nice guy too! read more

We had them come out because our pilot light kept turning off and my husband looked online and thought it might be the thermo coupler. He wasn't comfortable changing it so had Jeffrey Gray Plumbing come out and take a look and my husband told him what he thought it was. He took out a volt meter and said oh no that's not it, told us he could change out our water heater for just over $2,000. My husband said no thank you, went to Lowe's and got a $12 thermo coupler, changed it and it's now been a month and our water heater is still operating perfectly!!! This company is a straight up RIP OFF!! read more

Woow! On time, below budget and great job. Really nice people, the kind you WANT in your home or business. Got the job done so easily and way below the other estimate. read more

Great Service from Jeffrey Gray Plumbing! Arrived on time, friendly, knowledgeable. The cause of the leak was located and the service person explained he had to do to fix it. I would definitely use them again. read more

I needed to replace my 24 year old water heater which was leaking very badly. I lucked upon Jeffrey on the internet and was very pleased with the results. He did not try to sell me services or goods I didn't need. He was very detailed and made it a point to show me the severity of the damage and his work was very cost effective in comparison to other places I reviewed. Thank you, Jeffrey. I highly recommend Jeffrey Gray Plumbing. read more
