A recent plumbing installation by L & S Plumbing

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.”

“We strive to build long-term relationships with our clients by providing them with reliable plumbing services that fulfill their needs. Ultimately, we want them to feel confident in our work, educated about their plumbing systems and valued through exceptional customer service.”

Plumbing innovations can shape the future of your home’s water system.
Plumbing is about more than fixing leaks—it’s about preserving the health of your entire water and waste system. Regular maintenance and quick repairs can prevent costly damage, but emerging technologies are also transforming how homeowners manage water usage and detect problems.

One of the most significant changes in the plumbing industry is the rise of “smart” water management tools. Products like smart water meters made by manufacturers like Flume and Phyn can track water usage in real time, sending alerts for unusual patterns such as potential leaks. “These tools are game-changers because they empower homeowners to catch small issues before they turn into big problems,” says Sergio Ledezma, office manager of L & S Plumbing in Burlingame. “Also, water-saving fixtures like low-flow showerheads and dual-flush toilets deliver high performance while conserving resources, and tankless water heaters offer on-demand hot water without the energy waste of traditional tanks.”

Over the past year, innovations like advanced pipe inspection cameras and hydro jetting systems have also enhanced plumbing services. “The RIDGID SeeSnake, for example, allows plumbers to diagnose issues inside pipes without invasive digging,” says Mr. Ledezma. “This technology reduces disruption and significantly speeds up repairs.” Other advancements include smart water meter shut-off systems like Phyn Plus and Moen’s Flo Shutoff, which not only detect leaks but can also automatically shut off the water supply to prevent significant damage. Some systems even offer earthquake detection, adding an extra layer of safety for homeowners who live in seismic zones.
From efficiency to safety, these plumbing technologies are reshaping how homeowners interact with their water systems. By staying informed and investing in the latest innovations, you can protect your home, save water and reduce long-term costs.

Customer satisfaction is a key concern for any successful business, but it’s even more important for plumbing companies that have earned Diamond Certified. For L & S Plumbing, keeping clients happy comes down to three factors: reliability, clear communication and honest pricing. “Customer satisfaction is crucial because it builds trust, leads to repeat business and generates positive word-of-mouth referrals,” says Office Manager Sergio Ledezma. “We want our clients to feel valued and confident in our work, so we treat their jobs with care, offer upfront pricing and educate them so they can prevent future issues.”

L & S Plumbing has been providing plumbing services for residential and commercial clients in San Mateo, San Francisco, and Santa Clara Counties since 2006. The family-owned and operated company has the training and equipment to install, maintain, and repair all types of plumbing fixtures, and it’s also qualified to work on gas lines, water heaters, and more.

Unlike plumbing companies that take an “assembly line” approach to each job in an effort to maximize their workload volume, L & S Plumbing prioritizes personalized service and transparency. “We take the time to explain every step of our work, which ensures there are no hidden fees,” says Mr. Ledezma. “We also offer preventive maintenance plans and detailed consultations to help our customers avoid costly issues down the line.”

Another distinguishing attribute of L & S Plumbing is its dedication to quality control in every aspect of its work. “Our quality control approach involves thorough inspections at every job stage, from the initial assessment to the final check,” explains Mr. Ledezma. “We make sure all of our work meets industry standards, and before leaving a job, we double-check everything to guarantee customer satisfaction and long-lasting results.”

They are expensive, but the quality of work is really good.

The quality of work is good and the employees know what they are doing. I get little to no information on what they do. I'm in insurance, so the detailed information is important. If they replace something and give no detail to what exactly they did, we can't follow through with the claim. It has been hard to get that detailed information out from them. That is one thing that is challenging when working with L & S.
