"Jake Q. from The Water Heater Company recently helped us with a tankless water heater inspection and descale, as well as installing a pressure regulator, valve, and some copper pipework. He arrived within the window for our initial appointment on 3/7 and was very professional and thorough. The job ended up taking longer than originally estimated, but it was clear he was taking the time to do everything correctly. A pipework part needed to be ordered, so he had to come back to finish the work. The follow-up visit was moved from 3/11 to 3/12 due to a previous job running long, and he arrived slightly after the scheduled window, but once on site he completed the remaining work efficiently and with the same level of professionalism. Overall, I’m very happy with the quality of the work and Jake’s attention to detail. Despite the project taking a little longer than expected, I’d recommend The Water Heater Company and would gladly use them again."

"Did a $59 consult only. Turned out the cost of repairing the old heater was almost as much as a new one, so we got a new one, and handled the install ourselves. Luis B was great, knowledgeable, friendly, didn't try to upcharge just to sell a heater, which we appreciated. Gave us an honest evaluation, several options, and was right on time. I will say, though, that the company failed to call me when he was on his way... not a big deal. All in all a good experience."

"Jose and Alex were very professional and friendly. They knew their job and did it quickly. We had a small problem with an electrical outlet which they diagnosed and worked around so that our tankless water heater works perfectly."

"I contacted California Drains because my parent's home was completely backed up to the point where dirty water was coming out from the drains inside and outside their home. They promptly answered and booked me in the same day. They were able to contain the water from continuing to come out of the drains overnight and returned the next day first thing in the morning to get the problem fixed. Price was very reasonable, and the workers were very professional. Left everything clean and drains were completely cleared. It has been months since they came and there has not been an issue since. 10/10 will highly recommend to family and friends."
