23+ years serving San Jose, Santa Clara, Sunnyvale, Cupertino and 13 more South Bay cities. Navien Certified tankless installs, trenchless sewer & water line specialists, and the crew that actually shows up when we say we will.
Two decades in. Same phone number, same license, same crew that started it. We built The Tankless Guys around one idea: pick up the phone, show up when we said, and finish what we started. It's a low bar. Half the South Bay's had to lower theirs to meet it. We didn't.
Full-service residential and commercial plumbing. Navien-certified tankless installs. Trenchless sewer and water line work that leaves your yard alone.
Answered calls. Named techs. Real quotes before we start. Warranty on parts and labor. Every job runs on the same standard we'd want in our own homes.
Nine service lines, one crew, one number. Everything below is handled in-house. We don't sub out the sewer work or the tankless installs and hope the other guys make us look good.
Leak under the sink. Wax ring gone. Shutoff seized. The stuff that ruins a Saturday. We show up, diagnose, quote a real number, and fix it.

Every review below verified through Trustindex. Real Google reviews, real customers, real crew members mentioned by name.
“Came on time and addressed the issue. Very polite and actually wrapped up when I was not home. Finished the whole job in a day. Added extra work for themselves by getting rid of a PVC pipe that extended across the house for the sprinkler and instead attached it to the water line as it should. Great work — very happy with it.”
“The crew arrived on time, explained each step, wore shoe covers inside the house, and were very kind and clean. Exactly the professionalism you hope for when you invite a contractor into your home.”
“Isaias was very professional, friendly, efficient, and knowledgeable. He serviced and repaired my RO system, toilet repair, and installation of a new water softener. I would highly recommend to anyone. Thanks!”
“Isaias arrived when promised and did an excellent job replacing our garbage disposal and air gap as well as repairing a cracked pipe. All work completed in a little over an hour for the price quoted several days before. I highly recommend Tankless Guys for any plumbing work needed.”
“Great service starting with Gert then followed by the crew led by Sergio and Miguel. Amazing work, service, communication, reasonable price, good value for the money. Hire these guys — you will not be disappointed!”
