Plumbing reviews in Hayward, California

Title: Outstanding Customer Service – Thanks to Lavi!

Great people been a regular customer for years now for my plumbing needs, and while the company itself offers a great selection of products, what truly sets my experience apart is Lavi. Every time I visit, he goes above and beyond to ensure I find exactly what I need. His knowledge of the products, attention to detail, and willingness to assist make every visit smooth and efficient.

Lavi doesn’t just point me in the right direction; he takes the time to help me load up my purchases, ensuring everything is handled with care. His professionalism, patience, and exceptional customer service make Cal-steam my go-to place. Employees like him are rare, and I truly appreciate his dedication and hard work. If you’re shopping there, I highly recommend asking for Lavi—he’ll make sure you’re taken care of!

I made an appointment according to our schedule (old unit stopped providing hot water). Alex from Water Heaters Only showed up at exactly the correct time. After discussing various options I opted to purchase a new water heater. To my surprise Alex was able to install the new water heater while he was here. The job was completed in just under 2 hours. Water Heaters Only service their products 24/7 . . . not all companies service their products or fulfill the warranties . . . Water Heaters Only does!

From the quote to the end of the job, Loni was wonderful! When my water heater died the week of Thanksgiving, I thought I would be spending a week without hot showers, but Loni came through! During the quote, he was polite, explained things well, laid out my potential options, and came up with the best solution out of all the 6 quotes I received. He then returned on Thanksgiving morning, got the job done, and left me with enough time to still make Thanksgiving dinner. I am very thankful both for his professionalism and his willingness to work on a major holiday!

Prompt, courteous and efficient service to replace water heater burner within specified service day and time window.

Easy to schedule timely appointment. Prompt, courteous, efficient service. Installation was in a restricted access unfinished basement which required 2 technicians. Job was completed by highly competent professionals. Highly recommend this company .

Our Water Heaters Only technician, Loni, was fantastic. Our 27 yr old water heater was producing very little hot water and Loni provided everything you would hope for in this situation. He arrived on time, communicated clearly what the problem was and his recommended solution, and then did top notch work installing the new water heater. On top of that, we had the new water heater installed within 2 days of first calling Waters Heaters Only.

I found our water heater tank was leaking in the morning of 9/17/24. I called the company around 10am. A lady told me that a technician would be coming around 11am to 2pm. I received a confirmation text message around 10:30 am that they would send John A. to our house. I received a call from John around 11:00am and he showed up around 11:15 am. After a quick inspection, John clearly explained the options that we could consider. And he provided a quote on the spot. I agreed with the quote. John patiently explained to me about the scope of work. And he did a great job to replace with a new tank. Very speedy, responsive,and professional! Highly recommend!

We had a very old water heater that was failing us. I messaged through Yelp and they were very fast in their response! They don't have a lot of reviews on Yelp but it now makes sense because they use a google review service to leave feedback, so don't feel alarmed like I did initially! I made contact with them on a Saturday and a tech came out the next day which was pretty awesome. Our tech Luis was so nice and friendly. He did a great job. He replaced our water heater before even manning the BBQ at his home later after his work day way done! I would use y'all again 100,%, but not until this nice shiny new one fails us a long time down the road! Thank you for great service.

The installer was great. On time, friendly and professional. Did not leave a mess. Thank you!

Very impressed, extremely responsive. Chrys Zamora was on time, quoted a fair price and explained what was needed. He did not have the tank I needed in the truck, but drove to the warehouse to pick it up, returned and installed it. Everything is working fine. The next day I had a question, emailed the office and received a reply within 15 minutes. I would definately recommend Water Heaters Only. It's exactly what you want in a business - nice people, responsive and fair pricing. Thanks Chrys.

Excellent service from booking; text updates; service call on time; able to repair immediately with parts on hand. Steve is an excellent repairman who I trust and would certainly use again. Thank you to your entire team.

Daniel Chavez was great! He was informative, dedicated and committed to answering all our questions and making sure the water heater replacement process was smooth. Great customer service. He was on time, went above and beyond and maintained a clean work area. Friendly and professional. Great job Dan! It was a pleasure working with you!

Very responsive and arrived within an hour after the time we called for assistance. Super professional (they know water heaters!) and solved the issue quickly. We bought our water heater from them and felt confident reaching out for help when a code was set off for unknown reasons. Recommend them most highly!

Very professional and competitive prices. Quality and timely service. Will did a stellar job removing my old water heater and installing the new one. He was enjoyable to work with and helpful with questions/concerns. I would ask for him again anytime!

Truly appreciate working with Water Heaters! Wesley is exceptional and easy to work with. They are very professional, prompt, and easy to work with. Pricing they were very competitive and their expertise set them apart. Only person to go under my house to check everything out properly for a no surprise quote! This one goes on my list of must haves for my homes.

Confirmed 5 stars (would give more if possible). Wes came back as we had a possible water heater issue. He diagnosed our house's water pressure was too high (120 psi) and noted the regulator connecting into the home was inoperable and causing isssues throughout our house's plumbing. Amazing, plumber is coming to fix our issue tomorrow! Thank you Wes, our go to Water Heater resource.

Called to replacement an old water heater. Got an appointment the very next day. Great communication with company and service tech. Loni was courteous, highly professional and technically proficient. Give him a raise! Would definitely recommend this company for any water heater needs.Thanks you!

Home water heater leaked Friday midnight and I was able to get an appointment for Saturday afternoon. Sean Lee arrived around 3pm, greeted us pleasantly, evaluated the condition, and gave an estimate of cost and time. Once I gave approval, he got started immediately and completed the work in less than the estimated time. We have hot water for Saturday night. Thank you Sean! Great job!

Wesley did a great job taking care of my required replacement hot water heater.
It is never a good day to wake up to lukewarm hot water, but Water Heaters Only was quick, efficient, super careful with the property. They made a bad day better.

Wow! This is a very good, professional company that went above and beyond. Our 14 year old water heater broke, so I called and spoke with Alex and later Cyrus. Both were friendly and provided me a reasonable estimate for replacement and sent technician John out for next day service. He did an impressively clean install job, replacing hardware such as the gas line, strapping, adding grounding wire, and more in a short amount of time I had hot water again. It was a great value and I feel confident their work will last for many years. Thank you!

Lucas P. replaced my 20 year old water heater. He was very knowledgeable and made me feel confident that he would do a good job. I was not disappointed. He did a great job and I now have a new water heater I am can trust was installed by a true professional.

Great experience much better dealing with them than the big box stores that give you the run around. You instantly talk to a knowledgeable person over the phone. Water Heater only, I called them they delivered an excellent product water heater and provided prompt customer service. Prices are all the same, but the service and experience is much better.
