I’ve had a lot of work done with them, from my home to multiple properties I manage. Most recently, they completed a major underground leak repair. Everything was done in a timely manner with open and consistent communication throughout the entire process. They are always responsive and available often the same day or the very next. They also clean up thoroughly and never leave a mess behind. I will absolutely continue to use them time and time again.

This company went above and beyond for me. They were extremely knowledgeable, very affordable, and truly cared about helping me and not just fixing the problem. They took extra time, explained everything clearly, and made a stressful situation so much easier. You don’t find service like this often anymore. I’m beyond grateful and highly recommend them!

I recently had a major issue with a cracked pipe under my house that was causing foundation problems. After receiving three different and conflicting quotes from other plumbing companies, I was feeling overwhelmed and unsure of how to proceed. That’s when I called Longoria, and I am so glad I did. Eli from Longoria came out and immediately stood out from the competition. He took the time to explain why the other companies' assessments were incorrect and even showed me the exact location of the crack using his scope. His explanation of the necessary repairs was clear and made perfect sense. Not only was Eli's diagnosis more accurate, but his quote was also 40% lower than the others, even though he recommended doubling the amount of tunneling to ensure a thorough and lasting repair. Once the work began, it was clear that Eli’s initial assessment was spot on. The other companies would have cost me more in the long run with their incorrect and incomplete solutions. During our conversation, I mentioned that several foundation companies had told me I needed to fix the plumbing before they could address the foundation issues. Eli informed me that Longoria also specializes in foundation repair and referred me to his colleague, Robert. Just as with the plumbing, I had received three other quotes for the foundation work, and none of them left me feeling confident. Each company suggested repairs in different areas of the house, and it felt like they were all just guessing. When Robert came out, he provided a thorough evaluation and explained in common-sense terms what needed to be done and why. Robert’s recommendation involved installing more piers than the other companies had quoted, yet his price was still HALF the cost of the competition. His team uses high-quality steel piers that are pushed 15 to 20 feet into the ground to a pressure of 10,000 PSI. A solid concrete piling is then placed on top of the steel pier to support the house. I was in the house when they raised the foundation, and the results were instantaneous. The large cracks in my walls sealed up immediately, and the expansion joint on the side of the house returned to its normal position. To top it all off, the work comes with a lifetime warranty, giving me complete peace of mind. Throughout the entire process, both Eli and Robert were incredibly responsive to all my questions and went above and beyond to ensure the work was done to the highest standard. I am so grateful to have found a company that is not only honest and professional but also delivers top-notch results at an affordable price. Thank you, Longoria, Eli, Robert, and your amazing teams! I highly recommend their services to anyone in need of plumbing or foundation repair.
