Used Cupertino Plumbing after looking through Yelp reviews. Their customer service and response time was excellent. I had an annoying hammering sound coming from under the house right under the bedroom. I had investigated online and through my own plumbing knowledge, my Dad was a plumber, I thought the Pressure Regulator needed replacing. After talking with Frank on the phone Danny came out the next day and he was great to work with. Danny listened to my concerns and my opinions with great patience. He added his own work experiences with hammering and agreed the Pressure Regulator was the correct starting point. At the same time a Heat Expansion tank needed to be added. The very next day Danny came out and installed a new Pressure Regulator, swapped all the old galvanized for copper and brass, and installed the Heat Expansion tank on the water heater line. Danny communicated when he would be arriving and what work he was doing every step of the way. I found Danny's concern for everything to go to my satisfaction to be very genuine. When I called him regarding a noise the new expansion tank was making he came out the very next day and tried to diagnose. The noise returned over the weekend and on Monday Danny was out to install a new Expansion tank. During that time Danny noticed the cold water line from the Hot Water heater was hot to the touch. The water heater was 14 years old and could be causing some of these noises with the expansion tank. I did not feel Danny was up selling me but giving me ideas and options for what could be happening. I knew the water heater was reaching its end of life and decided that having this great service with Cupertino Plumbing and Danny I would go ahead with a new water heater. The hammering sound is gone and I am happy to have found my go to plumbing service in Cupertino Plumbing. Danny always wore his mask during all visits. I would not hesitate to call them again. read more

Frank, Thanks again for patiently guiding us through the Grohe repair process. Yes it's expensive and watching the job being done yesterday on our 20 year old dripping shower fixture I can see why. I can see why Grohe recommends Cupertino Plumbing and no one else in the bay area. I would trust no other plimber in the area with these fixtures now that I see what is involved. Prior to calling Grohe for a recommendation I had asked a 5 star yelp rated plumber to take on the job. He was immediately in over his head. He was trying to repair the water mixing fixture instead of the hot and cold water valves responsible for the problem. He couldn't get it apart so he gave up. He then recommended cutting the fixture out of the tile covered wall and replacing it with a lower quality American Standard fixture for $1500. That would have been a very big expensive mistake. I called Grohe and they recommended that we only allow Grohe approved plumbers to work on these fixtures. The only local approved Grohe specialist is Cupertino plumbing. I am very happy with the final result and so glad I did not go through with the other plumbers recommendation!! read more

Our house needed a complete copper re-pipe, including the pipes from the house to the city water meter at the curb. Another house on our block had had this same re-pipe about six months ago and highly recommended Cupertino Plumbing. The general manager, Frankie C.,was able to provide us with an estimate the same day we requested it, and said his crews could start the next day! Eric and his crews were on time and very productive. The work was accomplished on schedule, at a reasonable cost, and the results were excellent. During the work, Frankie was available to answer all our questions promptly. The job went so well that we decided to replace the faucets in our 5 sinks at the same time. This was also done with efficiency and dispatch. To connect our house to the water meter required tunneling under two sidewalks and a 3-foot retaining wall. A section of brick-on-sand paving in the parking strip had to be lifted to access the meter. All this was accomplished without a hitch, and I was particularly impressed with the great job done to replace the brick paving. In all: excellent work! read more

Definitely would use them again! Tom came out for what I thought would be a "simple" repair job. It turned out to be much more complicated, but Tom stayed put and did a fantastic job in a very reasonable amount of time and for a very reasonable fee - keeping me updated about any additional work and/or charges the whole way through. When I had a second issue, the owner, Frank, called me personally to discuss before sending Tom out again. Tom arrived promptly, as scheduled, and solved the problem quickly - no overcharging. They are very clear about their competitive rates and how they charge when you call for an appointment so, no one should be surprised (i.e., Hardy S. in Mountain View). And, in my experience, they do not waste time on the job or overcharge for parts. If you want to run all over town to pick up your own parts, you wouldn't save. This is a family business and they stand behind their work - no matter what size job. I'll be calling on them when I re-model my master bath. Thanks Frank and Tom! read more

Our hot water heater was not working.....we did call another company we worked with in the past....and they said send us pictures and we are going to charge you for travel time we sent them pictures but no response then when I called and they said we did not get. I went and looked at other companies and Cupertino Plumbing had a good rating so I called - got right through, the person I talked to was so helpful he gave me a high level quote and said when do you need we can get someone out TODAY...I was like terrific! They came out as promised but when they saw our tank they said oh what we have will not work but not to worry we will get the right one and come right back and they DID! They were so professional, courteous, and just nice to do business with! We had a new hot water heater that day!!! Going forward any plumbing issues I have I will call Cupertino Plumbing! Thank you! read more

I needed to repipe from the meter to the house. The existing pipe ran under the driveway, several brick sidewalks, and landscaping stones. I got three bids. The first two wanted to cut a one- foot slab out of the driveway, tunnel under the sidewalks, and rake back the stones the lay the pipe. They estimated three days to do the job including repouring the opening in the driveway. Their bids were in the $8000-$10,000 range. Frankl Cardia of Cupertino Plumbing told me he had a pneumatic piston that could go under the driveway and sidewalks without cutting the driveway, could do the job in one day, and bid about half what the other two were. I had my doubts, but the price was right. They arrived at 8:30AM; by 3:00PM, the holes were bored, the pipe was laid and we had water! If you want a plumbing job done right, fast, and at a fair price, Cupertino Plumbing is the goto company. read more

Cupertino Plumbing has come out to my house many times to repair plumbing, for example, plugged plumbing in my bathroom and kitchen sink, installing a water filter, a garbage disposal and repiping the water system in my house. Very recently Cupertino Plumbing remodeled the master bathroom in my house. Mr. Cardia came out to give me an estimate on the remodel and made several suggestions that I acted upon. I was concerned about the carpets in the hallway and bedroom would be soiled and my fears were unfounded as the plumbers and tiling experts laid out carpet protectors . The retiling was done professionaly and without incident of having to do extra cleanup on my part. I am thrilled that I have a whole new bathroom completed as written on the estimate writen up by Mr. Cardia. read more

One look at my old water heater told me that it was time to stop procrastinating. Called Cupertino Plumbing, They came out inspected the old water heater and told me my options. Replace with the same or a tankless water heater that does not reside in the house. I opted for the outdoor tankless option. They ordered the materials and scheduled the work. I actually had to cancel and reschedule which Cupertino Plumbing accomodated with no complaints. The plumber that arrived was clean, courteous and professional. He installed the water heater and took the time to explain the maintenance requirements. They took away the old heater, and removed the unnecesary piping that was left. The plumber even inspected my handi-work at my request and gave me a few pointers. read more

We though our sump pump underneath our house had failed and called our home insurance company who referred us to Cupertino Plumbing. They responded within 48 hours and on the day of the appointment actually called and requested to come out earlier than scheduled. Plumber was very professional and friendly. He assessed the situation and informed us nothing was wrong other than maybe our float switch may have gotten stuck which caused our alarm to go off. He made sure to tell us that he would not charge us due to free estimates and was very helpful with recommendations on how we can prevent this and other issues from happening in the future. Next time we need a plumber we will be sure to call Cupertino Plumbing! read more

I had a leaking water heater on Sunday night. I tried calling several plumbers but they were not available (even though I told them I had an emergency - I did not want my house flooded!). The other plumbing companies only had receptionists who answered the phones. Fortunately, I called Cupertino Plumbing and the plumber who answered was able to walk me through the process of safely shutting off the water and gas lines. The next day, Cupertino Plumbing came and had the 50 gallon replacement water heater all ready for installation. The installation took a few hours and the plumber was very friendly and courteous and answered all my questions. The price was reasonable and everything was working fine afterwards. read more

I had been thinking about getting my galvanized pipe replaced in my sixty year old home for a while and looked around for the best contractor. After dissatisfying talks with many people I remembered my neighbor had the same repair done. She directed me to Cupertino Plumbing. Frank came out and gave me an estimate that was fair and comparable to the others I had. I decided on his company and I am glad I did. There service was excellent, their crew was extremely helpful and professional. The cleanup after can not be faulted. All in all, I am very happy with the results and would make the same choice again. I just wish I would have done it earlier. I had no problems with the work and am very happy with the results. read more

I was very happy with all the work Cupertino Plumbing completed. We had major sewage backup in our house. Owner of Company contacted me right away. We had extensive pipes replaced. They were always on time. Completed the work in time they estimated. Explained extensively the problems and solutions. Everything now is working great. The owner took care of all the major details of contacting the City several times, making sure proper permits were signed off, and always got back to me when I had questions right away. So did not have to spend anytime contacting city inspectors or scheduling appointments. The owner took care of all those details. I will certainly use them again if I need to. Lyn B.

My company sells and manages residential properties and we have been in business for over 35 years in this area. We have had a great deal of experience with various plumbing contractors during that time and based on those experiences, I would not hesitate to recommend this company. Our clients expect us to use qualified workmen when we have plumbing work performed and Cupertino Plumbing has never disappointed us. I estimate that we have used them for more than a dozen copper repipe projects as well as for many smaller jobs and they have always impressed me with the quality of their work. I always feel confident that the job will be done right when I hire them. read more

We have had a problem with our water pipes for a long time. We put off having them replaced but finally decided to go ahead and do it. We got several estimates and ultimately chose Cupertino Plumbing. Frank, the owner, came out and met with me and my husband. His presentation was very thorough and he patiently answered all of our questions. The plumbers came out as scheduled and worked full days. Dave the lead plumber was really nice as was his helper and they cleaned up after themselves. I can't say I enjoyed having my water turned off but they had it back on that same day. I will definately refer Cupertino Plumbing to my friends. read more

I've used Cupertino Plumbing for a number of jobs over the past 20 years on two houses, and again just recently on a sewer line replacement. They did a copper re-pipe ~ 16 years ago which is still working perfectly, and the most recent sewer work was very well done. About 10 years ago I purchased all my bathroom fixtures from them for a bathroom remodel. In all cases I've always found their employees easy to work with. They are very good about getting the permits and arranging inspections, which is a big plus. The owner provides the quotes for the work, and goes over the details of the job on site, which is also a big plus. read more

I had a fantastic experience working with this team, and I specifically want to highlight Danny and Frankie. Danny's actual work was absolutely top-notch--he is incredibly detail-oriented, efficient, and clearly takes a lot of pride in what he does. The quality of the final result exceeded my expectations. Equally impressive was Frankie's professionalism as a manager. He kept everything running smoothly, communicated clearly throughout the entire process, and ensured the project was completed to the highest standard. It's rare to find a team with both exceptional hands-on talent and strong leadership. Highly recommend! read more

These guys came over when there was a disgusting smell coming from under my house. They got someone over who cleaned up right away and got the pipe fixed the same day. I was only down for one day and though it was more than I wanted to spend, I'm pretty sure it was a good price. I liked that I could talk to the owner, Frank, and then his son came over, a nice kid who seems to know what he is doing. Clearly the one star yelpers don't have any idea what plumbers cost and the difference between having a guy with a license and a guy working out of the back of his truck at Home Depot read more

User Rating: 5 out of 5 stars - great company, great work by Aleen 02/11/2010 Frank and his team did a complete copper repipe on my home December 2009. It has been great to have water available when it had previously been somewhat slow due to the age of the pipes. On the last day of the job, one of his team members came by to review the work that was completed, answer questions I had about shutoff valves and do a final clean up. The team did a good job. Everyone was very nice. Frank took care of the permits and I am happy the job was completed before the holidays. read more

We contacted Cupertino Plumbing, as we had a leak with the main water service line from the meter. Cupertino Plumbing was quick to respond, with Danny coming onsite to provide an estimate. He always responded in a timely manner to my questions and addressed all the concerns. Danny and his team were clear on what work was needed and how long it would take, and finished the job on time and cleaned up as needed. I felt comfortable with them, and will definitely recommend Danny, and the Cupertino Plumbing team to my friends and family for any plumbing projects. read more
