They are an incredible company—reliable, knowledgeable, and always punctual. Over the years, I have consistently received excellent service from them. As a property manager, I can confidently recommend their team for any task, as they handle projects of all sizes with the same high level of quality.

Fantastic. I called other larger chain plumbers first and they estimated ridiculous prices. Called Marin H20 and they came in very reasonable. And I'm so happy with their work - they also ultimately did a ton more than I originally asked for. I've found my plumber !!

450 Architects hired Marin H2O to help one of our clients determine why they consistently had sewer back-up issues. After a few hours using a camera to scope the lines, they determined exactly what the issue was. Josh, their technician, was very helpful and had a great attitude. I highly recommend the Marin H2O team. Richard Parker, AIA, LEED AP, Principal, 450 Architects
