Recommended Customer Reviews

Excellent service, fast reaction time, great communication. Fixed our issue quickly and professionally. Honest, easy to work with and very happy with the results. Would use their services again without hesitation. Gurt and Daniel L. Did an awesome job

Both Gert Visser, Sergio Rico, and their team were a pleasure to do business with. They were upfront and professional throughout the whole process. Compared to the other plumber I contacted, they identified the issue immediately and provided step-by-step and detailed options to resolve the problem. I will reach out to them for all my plumbing needs and for the larger scale project in the next year ahead.

Gert, Sergio, Rey, and Daniel (?sorry if I got your name wrong) deserve 5 stars for their service. They were the 3rd plumber company I called to solve an intermittent hot water problem, and they diagnosed issues with patience, told and showed me exactly what's going on, transparent and on-time. After that didn't resolve the issue, they quickly went back out and were able to fix the shower valve.
They even called the water heater company to double check that our flow rate was right and nothing was wrong with the heater, and reconfirmed if the softener was working correctly.
I'm very pleased with their service. Even though not the cheapest, is very high quality and people who cares about my full house water system and not just trying to make some quick bucks.

These guys are great! Courteous. Transparent. Knowledgeable. On time. Professional. Did amazing work. We would absolutely recommend them and will use them again for future work.

Service guy Sergio is very professional, patient, and responsible. The company is operating in a very efficient way and communicating each step clearly and quickly to clients, so there is no surprise. I feel safe to work with Sergio. I will definitely refer him to my friends.

tankless guys were so quick to respomd and diagnose and fix the problem between my dishwashet snd sink . kind and efficient. thank

If you're looking for straightforward honest professional clean timeless work, this group is for you. This group found numerous deficiencies In my property caused by my previous hired Plumbers. The two major deficiencies they found on my property were the improper installation of my toilet and the installation of the water wast line. They are exceptional group of professionals.

Good value, excellent communication and follow up. Straightforward guys who make sure the job is done right.

Sergio and his team came to our rescue after we had our water heater shut off by PG&E for a safety issue. We received a detailed estimate after a thorough evaluation. Sergio provided us a range of options and patiently answered all our questions. We decided to also fix other issues we'd been considering and we were provided with a fair estimate for completing all the work at once. We agreed to also install a pressure regulating valve and a home filtration system. The Tankless Guys team was punctual on the day we began the work. They did the best they could to minimize disruptions, letting us know when we would have a water interruption and returning it as soon as possible. I was impressed by their professionalism, communication throughout the project, and attention to detail. They took their time to clean up the area they were working on at the end of the day, covering potential hazards and marking them off, and organizing the space to begin the next day. The team did uncover a couple of issues in our older home, which caused the project to take a little longer. They did not cut corners - Sergio, Daniel and Ray took their time to fix the issues so the installations could be installed properly and up to code, and to avoid other problems in the future. We are thrilled with the quality of the work, the attention to detail, and the peace of mind that our home is safe again. It was a pleasure to work with the Tankless Guys! I'm sure we will call them again for our next plumbing project.

The Tankless Guys are our go-to for our home's plumbing needs. In the past, they expertly assisted us with our tankless hot water heater, and recently installed new faucets in our kitchen and guest bathroom, replaced old pipes, adjusted water pressure throughout our entire house and cleaned filters. Additionally, they are very communicative, timely and have reasonable prices.
