Fernando was extremely thorough and responsive to understanding the problems I had with my existing plumbing under the sink. He listened well to the sequence of how and when my kitchen was remodeled, and then explained where previous mistakes were made and how serious they were. He then addressed how to approach my immediate problem with installing a dishwasher. And subsequently provided a quote for the work to be completed to correct previous errors. Nahman is lucky to have Fernando working for the company. I recommend him highly!
