Longoria Plumbing has been a great resource. I work in real estate locally and coordinate with contractors for a wide range of projects, and this team has consistently been professional, responsive, and straightforward to work with. They communicate clearly, show up when they say they will, and complete the work in a timely manner. Everyone I’ve interacted with, from the office staff to the crew on site, has been friendly and respectful. If you’re looking for a reliable plumber, foundation, and/or sewer company who does solid work and keeps the process simple. I highly recommend them.

Longoria Tunneling and Plumbing repaired a broken water line at our apartment complex (Villa De Oro). The works were very courteous and and understanding of the tenants concerns about when the water would be turned back on. They cleaned up the area they were working in.

Hot water wasn't working and they came out in a very timely manner. They did a very thorough inspection and discovered that it was the auto shutoff device that I was unaware of. After turning it back on they made sure everything was working before heading out at no cost to me since this was part of the initial inspection. I appreciate the service and for helping me understand more about how my water heater works. Definate reccomendation!
