Longoria Plumbing & Drain Services is a great family-owned business. They were very honest, professional, and offered a fair price. I’m very happy with their work and highly recommend them!

Due to Texas clay soils and foundation issues I had to replace my entire underground drain pipe, a very expensive headache. I got quotes from over 10 companies and Longoria was the only reasonably priced company. They worked with my existing plumbing assessment instead of wanting to charge extra to perform their own. They communicate well, show up on time, and took good care of me. They got the job done in a timely manner and even took care of other minor issues like uneven toilets and a leaking water spigot. This was a big job that required a full tunnel underneath my entire house and Engineer inspection of the plumbing from the foundation repair company. Longoria worked well with the foundation company and Engineer and had no issues on the inspection. I am really grateful to Eli and crew for taking care of my plumbing and making the process as painless as possible. I will always recommend them to everyone.
