Marin H2O came out very quickly last night to fix the leak in the apt. upstairs and address the water that had leaked through to my apt. as well. Great service!

All plumbers are NOT created equal. They blasted through the clog, showed me the problem and fixed it. They are completely professional, have high tech equipment friendly professional servicemen and they get the job done when others can't.

Bob N.
