We had a water heater problem and they fixed it quickly

We had a pretty large clog in our kitchen sink drain pipe that came about pretty suddenly (I'm sure it was building for a while). Warranted Plumbing was exceptionally fast with response time and scheduling an appointment same day. Luis and Samuel arrived on time and completed the job very quickly. They were both very professional and very kind. Hopefully I won't need any plumbing services for a long time, but if I do I will definitely be using Warranted Plumbing!!

Quick response!
Paul came to fix our kitchen faucet that was moving. He came the day after I called and fixed our faucet.
Very good service and on time

I hired Arch to fix a botched plumbing job (bathroom sink fixture installation) by another company. I'd gotten an estimate from another plumber, who quoted me what I felt to be too high a price. That plumber didn't really take the time to investigate what the problem might be, just said it could be a really time consuming job.

Carlos showed up and his attitude was totally different from the 2 previous plumbers - he was actually upbeat and friendly and didn't complain about how hard the job was, like the other 2 did. He actually took the time to investigate the source of the problem, and then explained the possibilities and my options in a way that felt completely transparent and also easy to understand. From the way he talked about it, I felt confidence that this guy knows what he's doing. We'd agreed that I'd go back to the original plumber and have them fix their mistakes (and Carlos wouldn't charge me for giving his assessment), when he decided to have one last look. He identified something that could be causing the problem and was able to fix it, and also finished work left untouched by the OG plumber.

I was super happy with the outcome and that I didn't have to go back to the first plumber. Carlos mentioned that he enjoys doing plumbing work and it shows in both his knowledge and attitude. When a service professional explains the causes of a problem and your options for fixing it, your confidence in that assessment depends not only on the words being said but also the attitude of the pro. It's hard to believe a grumpy, unfriendly plumber. Thanks, Carlos, for making a stressful day better and for a way better experience than I expected! You guys are now my go-to plumbers!

Geoff Albertson has cared for our plumbing for the past 6 years. He first installed a sump pump in our flooding basement. Took the massive industrial pump left by previous contractor off our hands and replaced it with an appropriately sized one for a house. No more flooding. Such a relief to find someone willing to take over a small scale job some else didn't finish.

When we wanted to upgrade our tiny second bathroom, Geoff designed us a great one. We were especially happy with the solution he thought of that gave more room in the corner shower without crowding the sink and toilet. This job would have been within budget if we hadn't opted for a high end rain shower fixture.

Over the years he has replaced a disposal, fixed faucets and drains, ran our rear irrigation piping under the sidewalk and brick wall and installed a gray water system in our garden shed.

We enjoy working with Geoff Albertson. He is personable, appreciates copper, fits our small jobs into his bigger ones. We've referred him to appreciative friends.

Great communicator and knows his stuff.  Showed up on time and on Christmas Eve, no less, to connect our dryer.  Now, we can wash clothes and be comfortable when guests arrive.  I would definitely call them again.

Wow great service! We had a backed up storm drain, I called a few plumbing companies but just got voicemail.  Diamond Plumbing answered the phone on the first call and had an appointment set and the drain unclogged within an hour!  Couldn't be happier!  Thank you!

Sunday evening, hot water spraying out under bathroom sink. I was looking for a 24 hour emergency plumber. I am 70 and unable to get water turned off. I called and he informed me that they were not open on Sundays, but give him a few minutes and he would be right over in less then 10 minutes.  Here comes this wonderful man named Michael and fixes the problems right away, I felt so bad taking him away from his family at 7:30pm on a Sunday. a Fantastic man, there to help, showed me where outside off valve was and suggested that due to the age of the valve it really did need to be replaced, but he didnt pressure at all. I will be having him install a new valve and also have a few other projects around that I will be having him do also.  It is wonderful to see that there are still people that really do enjoy helping others in need.  If you need a plumber for anything, give Michael and his company a call, you will not be disappointed. They really deserve way more then 5 stars!!!

They just completed our sewer-lateral overhaul for Alameda Co. compliance.  Service is professional, amicable, and transparent  ((quoted price for the work and final invoice were nearly identical))  Also, our sewer lateral was especially deep-down, but was apparently no problem for Will and his crew.   10/10 would recommend, and will certainly be calling them back for internal plumbing work in the coming months.

Our water heater failed and we had to have it replaced right away. They were fast to arrive and provided me a quote. I was back and running by the afternoon. Excellent service

Good experience. Knows the business well, explains everything, doesn't up-sell, explains everything & then asks you what you want to do after options covered. I'll repeat service because of the honesty here.

Bill is the real deal plumber.  He is honest and dependable and knows his trade.  If follow-up is needed he comes back.

Sharky's Plumbing is professional and fast!! The owner even met me at Home Depot so I purchase items on my Home Depot credit card and he hauled the items to my house.  The service was so fast and he even gave me a discount on the pricing which was way lower than my Warranty Insurance.

Great service and can't wait to work with them again.

What more can I say about Michael and his crew Kit? I spent about 3 months planning on a backyard renovation which included adding a gas line to my fireplace so why not add 2 additional connections for a BBQ and fire pit. Kit came on scene and provided a honest quote for approximately 1 day of work. I accepted and the job was completed professionally and quickly. There was just 1 minor glitch but Michael made sure it was taken cared of within 24hrs. So far this has been the simplest part of the renovation. When I finally decide on adding the fireplace insert and fire pit I know who to call. Thanks Michael and Kit for the clean and professional job you did. I wish more contractors would be as concerned as Michael about pleasing their customers.

The team was super quick to respond to my bid on Yelp, and scheduled me right away for the next day afternoon, which was amazing since it was a Sunday. Mike came on time, changed into bunny shoes to keep my apartment clean, and started on the job immediately. Unfortunately, the job couldn't be done due to the weight limitations on my wall, and I have to say I extremely appreciated their professionalism to rather not be paid for the job than to install something that was not safe. Mike was super nice and friendly! I would recommend them in terms of their approach and professionalism.

Very very good at his work. He came on time and finished his job by staying couple of extra hours. He is very professional and efficient.

I have nothing but good things to say about Ron at Maintech. Punctual, friendly, knowledgeable, honest and his prices are very reasonable.

Mario is great! Came over within 20 minutes and got the water heater working again. Best part is he was honest and transparent. Another plumber was talking about replacing everything for thousands of dollars. Mario got me back on track quick and gave me affordable options for the future.

Responded ASAP with a quote, gave very reasonable flat rate for the job, came on short notice, wore a heavy duty mask. It was my first time needing to hire a plumber and he was friendly and knowledgeable and solved the problem ASAP, and then did some testing to make sure it stayed solved. Thank you again!
