Giovanny was very professiona. He called to advise me he was on his way. He diagnosed the problem and had the expertise to fix it. We called Bill Howe for a second opinion after a prior plumber told us he had to open up the wall the fix the drain. Giovanny was the right man for the problem. He saved us more than a thousand dollars because is well trained and honest. Thank you Bill Howe Plumbing and thank you Giovanni Martinez, I wiil recommend you to family, friends, neighbors and co-workers.
