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.
Our clients' needs are our top priority. We recommend the most efficient and budget-friendly options, ensuring they are done right the first time—guaranteed.
Gert, originally from South Africa, has called the Bay Area home since 2000. He brings over 20 years of plumbing expertise, including two years aboard a private yacht in the Bahamas.
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.
Gert and his wife spend their leisure time with their three and five-year-old sons, cooking, and cheering for the South African rugby team. The family has been local residents of Sunnyvale for over a decade.

Recommended Customer Reviews
Naomi D.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.
Bhavin P.I had a leakage issue for external connection. They throughly figured out the root cause and fixed the issue.
They explained everything in details and what to expect throughout the process.
Thank you very much for helping me.
Not the cheapest but I'm glad I called them. My wife complained about a leaking faucet, TTG came out and diagnosed the problem for free.
Turns out I had high water pressure.
They put in a pressure regulator to resolve the main issue of a leaking faucet(s), I'm glad Sergio educated me on the importance of a PRV.
These guys offer you the long term solution not the band aid fix.
The Tankless Guys far exceeded every expectation we had. Gert arrived at our home and had a wealth of knowledge to share across plumbing (of course), electrical systems, and heating, and was able to clearly and succinctly explain how these systems interacted to cause the issues we were seeing in our home. It was clear that Gert had enormous hands-on industry experience to draw from. Gert was prompt, honest, trustworthy, polite, and at no point did we feel pressured to spend money; it was actually quite the opposite, he went above and beyond to think of ways to save us money. He was able to diagnose our problems quickly and offered effective solutions and was very upfront about his costs.
I wish I could give The Tankless Guys more than 5 stars. Gert, Sergio, Daniel, and Miguel are such a professional team. They are hard working, efficient, clean, and above all, trustworthy. I had the pleasure of having Gert, Sergio, and Daniel working on a plumbing ""makeover"" of my house last year, and could tell they took pride in what they did. This year The Tankless Guys added a separate water shutoff line for my irrigation and did such a beautiful job. They go above and beyond what's necessary, and you get so much more than what you've paid for. The best part is that they are truly nice and honest human beings, something that has no price tag.
I highly recommend The Tankless Guys for all your plumbing needs!
Shortly after purchasing our first home, we started having issues with our main water line. Finding a company that was honest and affordable was key for us. That's where The Tankless Guys come in. Sergio visited our house and told us exactly what the issue was and what the timeline would be. We couldn't beat the price either so we decided to hire them and we are glad we did. We were very pleased with his professionalism and the detail in his work.
A friend of mine recommended the tankless guys after my water heater abruptly stopped working. They sent someone to my house the same day I called and were installing a tankless water heater the next day! If you're looking for quality work, this is the company!
