Recommended Customer Reviews

The workers were polite but the communication was not very clear. They took 4 hours repairing a leak in the ground. Although they needed to dig 1.5 feet to repair a 1""pvc pipe, it doesn't justify the repair cost of $953.00 dollars. I'm outrageous about the cost considering it's a pipe leak, even if the explanation given by the owner was that it's a Saturday. Think twice before giving them a call!

What great service? Our hot water heater needed repair and they thought they couldn't be available for 4 days because only a few staff were trained in our model. But they kept us on the list and the next day when they had a cancellation they came to do the repair. In addition, though another firm estimated over 3 hours at $250/hr., they took an hour at $165/hr, and were wonderfully pleasant and informative. They are our go to plumbers from now on.

one of the best plumbing companies I've used, I work for a property management company and every time I've needed any plumbing emergencies pacific plumbing has always been there regardless of the date and hour. Also, there prices are very reasonable. Special shout out to Carlos, usually he's the guy that gets send out to our property and always does the job right in a timely manner. don't get me wrong, I've seen the other workers job capabilities and they are really good as well but most of the time its Carlos here on our property. overall great service and great time management.

I am so grateful to Carlos for his great work installing my reverse osmosis kitchen sink water filter and to Pacific Plumbing for the way they do business. First off, the kit I bought online was missing a piece and Carlos hunted down the right part at my local hardware store and did it all so fast he was still able to complete all the required steps to do a proper installation in that one appointment. And second, I had a bit of trouble finding a plumbing business which would give me a clear estimate over the phone, work by the hour, and not charge me a flat ""consultation fee"" just for walking through the door. When I called Pacific Plumbing I was immediately connected to a person who talked out parameters of the job with me, gave me a clear estimate, including contingencies, and scheduled the appointment to come and do the work only a few days from then. All and all it was a wonderful experience and I'm recommending Pacific Plumbing to all my neighbors.

They did a great job for us. It took them few minutes to figure out the problem. They fixed it within 45 minutes and charged us a decent cost. I would recommend them for sure and would call them next for sure if needed. They respond promptly and work efficiently.

We needed an emergency 2"" domestic water line repaired in Hayward. Our regular service company was unable to respond with 48 hours on site, so we called Joe to see if we could get some help. He had a team there within two hours ready to rock and roll. Lamberto was the crew lead and immediately gave the open option of being able to start immediately hand digging once asphalt removed or waiting for the utilities to be marked if we preferred. I somewhat knew the layout of the parking area utilities and only had one gas line to be careful of, so I called my office and got our PM's approval to start without delay. Within two hours, they had found not only the line but the breach without waiting for any locators which to me shows exceptional skill on task for traditional plumbing. By 4pm same day the building was restored, lines flushed and trench safely back filled and covered to await paving repair.
Excellent service, professional work and timely..... timely was quite important here as we had a food service client down due to the line break.
Lamberto, Fernando and Antonio great job.

I had a good experience working with Pacific plumbing. I did Gas line trenching and sewer line replacement with them, which needed a lot of crews and time. Since they are a big company which has a lot of experience, I didn't have to worry about anything while I was working with them. They'd done their job properly and worked so professionally.

Pacific Plumbing recently came to our rescue in Livermore. A leak that required tracking down its source in a very odd plce, working me into a very short window and doing it for a more than reasonable. I would recommend Ron and his crew anytime.

I arrived home from a week long business trip to a house without hot water. I called on Friday afternoon, and Jose came out within 2 hours. He quoted me an all-in price of $2900 for the water heater and I assumed he was trying to rip me off. Then he explained that I have a 75 gallon power vent water heater and invited me to shop around and call him if I change my mind. No charge for the inspection and advice.
I called Home Depot, who don't carry this type of heater. Then I called Lowe's. Their model was $3,150 plus tax, installation and old tank removal, $3,800. Oh, and it would take 2 weeks to order the replacement. I called Affordable Water Heaters and Plumbing, who wanted to charge $4,990. Water Heaters Only would only say the cost would be between $3000-$3600, depending upon the installation expense and cost of new code compliance rules. They could install it on Tuesday.
I called Joe back. He said that he could get the new water heater Monday morning and have it installed Monday afternoon. He was also very flexible to work with my insurance company, because he wasn't on their list of plumbers in my area.
All in all, I'm satisfied with Pacific Plumbing for being reliable, friendly and responsive. I'd recommend them to any of my friends.
