The Tankless Guys (TTG) was established to address a gap in the local plumbing industry. Gert noticed a lack of quality service, integrity, and a commitment to solving plumbing problems while working for several companies in the Bay Area.

Gert takes pride in his ability to resolve any indoor plumbing challenges. His areas of expertise include traditional and tankless water heater installations, repairs, and replacements, as well as above and underground sewer and water lines.
In his spare time, Gert and his wife enjoy chasing after their two young sons, cooking, and supporting the South African rugby team. Having lived in Sunnyvale for more than ten years, Gert and his family are proud members of the community.

Recommended Customer Reviews

These guys are great! Prompt service and clearly explained our leaky pipe issue. Came in saw issue and fixed right away. Amazing service for a good price. Highly recommended.

Facing a plumbing emergency, I found The Tankless Guys on Yelp and they came out within a couple of hours. They were ultra professional and explained everything in detail. Their service was quick and efficient plus they delivered a high quality product at a truly fair price. They are now our ""Go To"" plumbers and if my experience is any example, if you need plumbing help, The Tankless Guys are the people to call.

I couldn't be happier with the service from Gert at The Tankless Guys Plumbing. ! From start to finish, the experience was top-notch. He arrived right on time, equipped with everything needed, and was incredibly professional throughout. It was clear he knew exactly what he was doing and took the time to explain the issues and options in a way I could easily understand.
The work was done efficiently and carefully, and I felt confident that I was in good hands. What really stood out was the fair and transparent pricing--no hidden fees, just honest, straightforward rates for quality work. If you're looking for a trustworthy plumber who gets the job done right and respects your budget, I highly recommend them
Thank you for making a stressful situation so much easier! A+++

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.
