After getting a very high quote from a major plumbing chain, we decided to contact Water Heater…read moreMasters. We had an absolutely fantastic experience with Water Heater Masters. Alex sent our technician, Rojo, who helped install a new 40-gallon gas water heater in our indoor utility closet, and he was incredibly diligent, professional, and efficient from start to finish. Installing a tank in an inside closet can be tricky, but Rojo handled the entire job seamlessly in just 2 hours. He replaced everything with high-quality components, including: * New hot and cold water flex lines * A brand new water shut-off valve * A new gas flex line and sediment trap * Fully reworked earthquake straps (to meet California safety codes) * Properly updated T&P line and venting He also took care of the removal and disposal of our heavy 18 yr old tank, leaving the utility closet completely clean. If you want fair pricing, expert specialized service, and a technician who respects your time and home, call Water Heater Masters and ask for Rojo. Highly recommended!

After a frustrating experience with another company, I'm incredibly grateful I found this team…read more My water heater started leaking from the second floor into the first, and I needed help fast. From the moment I called, they were responsive, professional, and honest. They were able to come out within an hour, which was a huge relief given the situation. The technician quickly assessed the problem and gave me a straightforward, fair quote $2,300 to replace the water heater, which was significantly lower than what another company had tried to charge me. No pressure, no upselling, just clear communication and solid work. They completed the entire installation in about two hours, and everything has been working perfectly since. You can tell they know what they're doing and respect your time. What really stood out to me was their honesty. I asked what they would have charged to replace my laundry room valves (something I had just paid way too much for elsewhere), and they told me around $350. That level of transparency says a lot about their integrity. If you're looking for a company that is reliable, reasonably priced, and professional, I highly recommend them. I'll definitely be using them again for any future plumbing needs.

They were the most competitively priced, easy to schedule, showed up on time, and were incredibly friendly. The installation process was smooth and professional--couldn't have asked for a better experience. Fast forward three years, and we suddenly weren't getting hot water. The only Rinnai approved plumber for servicing in our area came out and couldn't figure out the issue, which was frustrating. I called Hakim directly, and he came out the very next day and resolved the problem. His level of service was truly outstanding--knowledgeable, responsive, and great to work with. I'll definitely be a repeat customer and highly recommend them.

Enter Oakland Rooter & Plumbing. Jose, the plumber that came to service my kitchen plumbing, was kind, professional and very skillful.

Hired Water Heaters Only to replace a water heater in Hayward. Often the truest test of a quality…read morebusiness is how they perform when things do not go well. In my case, I have quite a story of having to go five days without hot water because the unit I received was defective. The day after the install we found the tank had shut down. After a reset and restart done over the phone with the installer assisting, the unit failed again, a short time later. The next day which was a Saturday, another technician came out to swap out a heat sensor which appeared to be the problem. While changing out the part, the tech noticed that insulation near the assembly had burned, and ash was present. He vacuumed it out and restarted the unit. It made a horrible noise, and he spent a half an hour on the phone with the manufacturer tech support trying to diagnose the problem. The noise eventually went away and he finished the repair. Unfortunately the machine shut down again after we got one warm shower. I called on Sunday, and explained that I was no longer comfortable with the unit being in our house and I wanted a replacement, of a different maker. Without hesitation they agreed, and Monday morning, after acquiring a, more expensive model of a different make from a supplier, we got a replacement installed, at no additional cost. These problems are rare, and not the fault of the installer. I could not have asked for a more timely and considerate treatment as a valued customer of this business.

I called Excalibur and they said this wasn't true. They could install a similar model of tankless water heater to the one I had. Their quote was almost $2000 less than the other plumber. I since had an HVAC company come out for something else and mentioned I had to change the heater recently. I told him what I paid and he said that was honestly a good price. Excalibur seemed honest and helpful and they were able to come out first thing the next morning and get my heater replaced. They did a good job and the new unit looks better installed than the original. They also gave me advice on how to maintain it and what maintenance I could do myself to descale it etc so it doesn't break again. Overall happy either way the service even though overall it was expensive it was still less than other quotes I got.
