Get matched with top tankless water heater repair pros in South Pasadena, CA

"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."

"I had my tankless water heater serviced by Daniel W. Daniel was throughly professional during his entire visit. I would highly recommend Wester Rooter for all of your plumbing needs."

"They promptly answered my request to repair my water heater. During the conversation, I asked about a tankless system. Mr. Leon explained the advantages and I purchased the tankless system. It was installed the next day and I am very happy with it."

"Vicâ s plumbing came to my rescue when I need them. They arrive on time and weâ re able to replace my water heater sooner then the other companies had quoted me. They are professionals and extremely friendly to work with. Vicâ s plumbing is my go to plumber."

"Very professional. Prompt. Tankless water heater has been working fine ever since. Hired another plumbing company before calling G M C. They were half the price. But did not solve the problem. David with G M C diagnosed the problem. Completed the work. No problems ever since. Thank you Angi, thank you David and G M C Plumbing."

"My family recently moved Fresno. When we lived in LA we hired Johns Plumbing to install a new water heater. It was 40 gallon Bradford White water heater. John gave a free estimate first. Then his team installed water heater. Victor and his helper worked fast and accurate. We highly recomend Johns plumbing"

"Stop looking for a plumber! Sam is the man for you job. I can’t say enough about him and his team. He worked within our budget, did top notch service, and even offered free advice for our other bathroom. Sam installed a tankless hot water heater, ran plumbing out to a brand new Adu, and helped us complete a perfect compact bathroom. Sam is a master of his craft and priced well. Thanks again Sam!!!"

"The repair crew is prsessional and also stayed calm in dealing with surprise conditions. Great services. Juan wrote up the quote, I thought he might be just sales,but he actually hand on did the work. He knows his staff!"

"Reliable. Honest. Good communication. Well trained workers. Willing to work with you to get what you want the way you want (flexible). Very happy with the job (offered me options on a water heater and I decided to take the tankless). No pressure either."
