company logo

L & S Plumbing offers a wide range of plumbing services to residential and commercial clients in San Mateo, San Francisco, and Santa Clara Counties. In addition to installing, maintaining and repairing all types of plumbing fixtures, the family-owned and operated company has the in-house capabilities to work on water heaters, gas lines, backflow prevention devices, and more.

Office Manager Sergio Ledezma attributes much of L & S Plumbing’s success to its focus on reliability, transparency and customer education. “From the start, we’ve prioritized delivering stellar work and clear communication,” he affirms. “We take the time to walk our clients through their options so they can understand their plumbing issues and feel good about their decisions. That approach has helped us grow into a second-generation business that works with some of the top general contractors in the area.”

L & S Plumbing prioritizes quality control throughout every step of the plumbing process, which Mr. Ledezma says is important for ensuring positive results. “We love being able to see our work from start to finish. Whether it’s the rough plumbing for a remodel or troubleshooting a complex issue, we take pride in meeting the highest standards of quality.”
