I have lived in the Bay Area my entire life and possess more than 30 years in the plumbing and construction field. My partner Alex Diaz and I were colleagues at a plumbing company, where we realized that we share the same goals and values regarding integrity, loyalty, customer service, and satisfaction. We dreamed to one day work for ourselves. After a few years, we chose to go into business together. From the beginning, our plan has been to maintain simplicity and foster a positive work atmosphere for our team and our customers. This is truly a family-run business, and all four owners are actively engaged. We find joy in tackling challenges and the creative elements of our work. Establishing this company with the Diaz family has been a gratifying experience. We are proud of our team and what we have accomplished together at Water Heaters Masters Inc..

Recommended Customer Reviews

The Navien heater is the class of the field. This is the one to buy for your house.
As for Water Heaters Masters, the installation was on time, quick and professionally done and the guys doing it were on time, clear in explanation left things tidy. And the price for all the work was fair.
Here's where you learn how good a business is, when there's a glitch. Our Navien had a problem after about a year and change and it was a difficult one to diagnose. It took a few tries, but they were really persistent, easy to schedule and wouldn't quit till they solved it. This is the best follow up service I have ever had. No product is perfect so it can happen, the difference is that they stand behind their work. My strongest recommendation for WHM!

There was a gas pipe leak behind the wall of the water heater. The technician came out on time, opened up the wall, found the issue, and repaired it at a very very reasonable price. I know b/c I compared it with quite a few other places before going with water heater masters.

Today Alex and team installed water heater on my property. Brian was the tech. Very nice and professional job. Brian was friendly and very professional. Work looks too class. Thanks to Alex and Brian for helping me on this.

We bought a house with an old water heater and no gas shutoff valve. I called WHM and they had availability for a same day site visit. The quote was good so I scheduled for work the following day and Sam got us hot water and a gas shutoff valve before our planned move in date. Sam is patient, professional and knowledgeable. I recommend WHM and will be using them for any future water heater or gas line needs. Thank you Sam. We appreciate you.

Came home after being away for several days to find the water heater leaking. I called several companies for estimates and all were responsive but WHM was not only responsive but substantially less expensive. Plus they came out the same day to do the work and did a great job. Kudos to Alex and Brian. Very pleased with the work, the price, and the professionalism.

These guys were just amazing all around in replacing our tankless water heater. Jorge did the installation and Alex was very helpful in consulting on a few questions that I had. Both took their time to ensure that we understood everything. The installation is clean and professional. We could not be happier.

After 16 years our water heater finally gave up. Called Water Heater Masters this morning and by this afternoon I had a new water heater installed. Sam, the service tech was awesome and did fantastic work! On time and competitive pricing with the Yelp discount applied. I would recommend this company to any of my clients, work colleagues or friends. Thank you for the quick and efficient service!

Water heater was nearing the end of its life expectancy and I wanted to take the initiative before a surprising blowout. Called on weds to get an estimate for a water heater replacement and met w/ Jorge. Jorge was very knowledgeable, experienced and professional and was clearly the right choice to go with. Jorge installed a new Bradford White water heater, valve, Grundfos circulating pump and made several modifications to accommodate the new install. He was very thorough, efficient and clean. Solder joints were nicely done and the overall install was great. I would highly recommend him for your next water heater replacement!

If I could give Sam 10 stars, I would. I've had this same problem of low hot water pressure throughout the house for years. I called WHM and they sent Sam out within a couple hours. He spotted the name of the heater, and said he had seen this problem before. He got straight to work and a short time later, fixed it. Now all the pressure is perfect.
(BTW, other companies wanted to replace the huge water heater, and wanted to upcharge me to bring 3 extra people to exchange the heaters up and down my stairway. When I inquired about a tankless heater, they wanted to redo all my plumbing and replace my gas line. The quote was over $10,000.)
I can't recommend WHM enough, and Sam. Such an honest and experienced company. WOW! Don't hesitate to call them. Their pricing was amazing, too.

Promptly responded to quote request. Readily scheduled service appointment within the same day as quote. Replacement job completed within the same day. High quality of products used and professional service was done. Pricing is upfront and no surprised of additions. Brian was excellent at his work and service.
