Recommended Customer Reviews

I have used Benicia Plumbing for many years and after the most recent visit, I realized that I have never posted my satisfaction with this company. The employees are knowledgeable, efficient, professional, and extremely helpful.
They always show up within the appointed time frame and they are prepared to analyze and solve the issues that I called about.
I am very pleased with their service.

Want a good honest plumber? Call Benicia plumbing.On time clean up behind themselves and are efficient communicators.Enough said.

I recently had a emergency water problem, called Benicia plumbing after getting recommendations from other people who had used them.I am so glad I did ,they sent out Chris figured out what my problem was and resolved the problem. Chris checked water pressure from the outside of my house all was ok, all possible causes were checked and were ok. we realized my toilet and all associated parts needed replaced. Which was done to my satisfaction. The restoration of my home from the extensive water damage to be handled by my insurance company. If you're reading this while trying to find a plumber look no further Benicia Plumbing is the one for you! I don't normally take the time to write a review but in this case I was so very happy I had to share my positive experience. Please don't hesitate to call , you won't be sorry.

We recently requested an estimate from Benicia Plumbing to install a toilet. After reviewing our request, the plumber used a water pressure meter on our water supply and said that our water pressure was over code and would require a additional expenose to correct before the toilet installation.
We called the City of Benicia water department to send someone to recheck our water pressure and the City person found our house water pressure to be within code requirements.
Benicia plumbing tried to overcharge us for an unnecessary water pressure device and used an inaccurate water pressure gauge to give us misleading information.

Excellent response time, quality service, fair price. wouldn't consider calling anyone else after our last two very positive interactions

I spent FOUR MONTHS trying to get reimbursed for emergency repair!
I contracted with Benicia Plumbing to replace a shut off valve and the waterline behind my fridge for the service date of July 10, 2023
The technician came and as far as I knew, performed the work I contracted and paid for - a water line and a shut off valve. As I assumed this company was professional, I did not check the work.
On July 14, my downstairs condo neighbor has a leak coming through her fan in her laundry area, from my home.
I immediately call Benicia Plumbing and they informed me that they don't have a service person to send to my home that day.
Anyone dealing with a water leak coming from an upstairs unit to the downstairs unit knows that this is an emergency. Since they didn't have a technician for me, I immediately started calling other plumbers and found one who could arrive in 90 minutes.
The plumber arrived and found the leak to be coming from the water valve that had NOT been replaced per the contract with Benicia Plumbing.
This plumber immediately sourced all of the items he would need to replace the valve, which included, cutting out sheet rock and replacing it, cutting out base molding and replacing it, and of course, all of the necessary plumbing supplies.
The unit downstairs sustained $600 worth of damage that I was also responsible for.
Carlos, the other plumber worked diligently for four hours on a Friday afternoon/evening, until 7 PM. The charge for this emergency work was $900.
Because the emergency repair was only necessary because the valve had NOT been replaced per my contract four days earlier, I submitted the bill for the emergency contractor working in my home and for the contractor working in the home below to Benicia Plumbing for reimbursement. I also requested a refund for the work that was NOT performed per my contract.
I sent a full detailed explanation to BP along with photos. Their response was that they had no idea where or when these photos were taken and they were not going to take responsibility.
I pointed out that there's metadata embedded in the photos that shows the time the date and location of each photo. The photos clearly showed the 20 year old valve and the fact that it had not been replaced per the contract.
Once I pointed this out, Benicia Plumbing said that they could not find the contractors licensing information for the two contractors that helped in this emergency. They said they would only consider paying if I could provide that information and if I couldn't, they would report these other contractors to the California State Licensing Board, which would cause them harm. They also told me they spoke to the technician and he said he replaced the valve and that he had been working there for 4 years and they trusted him. Hmmm....
Benicia Plumbing asked to come and do a physical inspection with a manager and the technician who insisted he replaced the valve - which he did not replace. I allowed the inspection to happen and it took me weeks to hear back.
When I did finally hear back, they told me they would only reimburse me for the $415 for the job they were supposed to have done. This was not a satisfactory response.
I was able to obtain all of the licensing and insurance information from the other contractors and sent it to Benicia Plumbing. I did not hear anything back for one month.
On November 6 I wrote, and informed BP that I had received counsel from a small claims court case manager for Solano, County, and that if I was not reimbursed immediately, I was taking this to small claims court. It did not feel good to me to have to use this approach. I have never been in small claims court and I would have gone if that's what it took to settle this matter.
I received a response from the manager that they would reimburse me for everything I requested.
From the day of the water leak until November 6, I put a lot of time and effort into having all of the proper documentation to have an ethical business transaction with the upmost integrity. This was very stressful for me, and I think their intention was for me to just go away.
My refund check has been received and I chose to write this review so others can have awareness of Benicia Plumbing's business practices.
There's actually more from earlier transactions with Benicia Plumbing, where I had contracted for something, set up service dates, and the technician arrives without the plumbing hardware they needed, or I had previously been told to purchase the wrong items. A different technician who had come out did not thoroughly review the scope of the job, missed quoting for important elements of the job, and the true bid ended up being $700 more than the original quote and contract that I had accepted. I had understood that the technician was at fault and agreed to pay the additional money and move forward with the work. Lesson learned. I needed to have canceled that job and found another plumber.

Michael our plumber was very nice. He looked over the installation process for a complex faucet and went right to work. He had us check everything out when he was done to ensure we were satisfied.
We've used Benicia Plumbing a few times now and they always send great plumbers and give quality customer service. Highly recommend.

I recently had my faucets switched out, as always they were professional and when they left it looked like they were never here. They left the work area clean. They have never disappointed me.

They were very prompt and cleaned up after. They put in new water heater and took the old one. Very nice serviceman. Used quality products and very polite

These guys tried to rip me off. I needed a new water heater, and called Benicia Plumbing. Simple job; water heater in the garage; standard 50-gallon. They sent out a guy to provide an ""estimate,"" which I believe is their way of sizing up one's ability to pay. He quoted a price of $3,500 to replace the water heater. (You read that right.) He then sent me an email with a single-line estimate. In other words, there was no breakdown of the labor, materials, etc. that would total $3,500. So, a 50-gallon water heater costs around $1,000 at the big box stores, and a plumbing company can get a water heater cheaper through a wholesaler. That means that they were planning to charge approximately $2,500 to install the new heater, which is a relatively simple task. Long story short, I was able to have the work done at a fraction of that price. I would look elsewhere.
