I just had Waialae Plumbing re-plumb my entire house in Manoa. Emelio was very knowledgable, friendly, and professional as the supervisor. His team showed up on time, finished on time, and did great work. Their estimate was also less expensive than a comparison quote I received. (Per Emelio, the poor reviews on this site were from a former employee that was let go...a litte suspicious that both were entered on the same date, don't you think?)
No reservations to use these guys again.
