In today's economy & status, it's hard to find a skilled professional in many fields, Mr. Longoria is one of those people. My Water Heater just quit, working in the morning, at 3pm, no hot water. I called Longoria Plumbing at 4pm, and he was at my house next morning with a brand new Rheem 50 gal heater. Replaced my old unit and hauled it off as well. Him and Longoria Sr. were at my house less than an hour, professional, tidy, & respectful. Honest pricing, very fair for professional plumbing. I've had the pleasure of working with him once before on a busted water main to my house, both times, fair pricing, professional work, and GREAT customer service. He is the PLUMBER to go to. 100% recommend his service & Company.
