"We are incredibly grateful to Pedro Galvan and his team for stepping in during a moment of urgent need. When our hot water system suddenly failed, leaving us without hot water for daily essentials, Pedro responded with a level of professionalism, clarity, and compassion that is truly rare. From the very first call, Pedro was attentive, transparent about pricing, and committed to solving the problem quickly. He provided us with the most cost-effective and honest quote out of several we obtained—and, even more importantly, was able to come almost immediately when others could not. His workmanship was precise, efficient, and tidy. It was clear we were in the hands of someone who genuinely takes pride in his craft.

"Excellent work completed in less than 24hrs. Wish I?d done my homework for average cost to replace a water heater. $2850 to replace 50 gallon gas water heater seems very steep. "

"I had an awful experience with Cupertino Plumbing. The plumber showed up, barely stayed for 15 seconds, and immediately started swearing at me, saying he didn?t care about the job. Completely unprofessional and disrespectful. If this is how they treat customers, I would never recommend them to anyone."

"Our garbage disposal jammed and made a horrible grinding noise. The plumber showed up on time, diagnosed the problem in minutes, and got it working again without trying to upsell us on a new unit. He was polite, efficient, and super easy to work with. The kitchen is back to normal thanks to him."

We take great pride in our experience, expertise, quality, and customer service that we provide to meet the consumer's needs. It is our mission to provide excellent workmanship and complete customer satisfaction, from the start to the completion of a project. In order to understand the needs and expectations of our customers, we take great care to work and communicate with every customer in a professional manner. Our reputation is based on service, safety, and quality, regardless of how large or small the job.

"We returned from vacation to find pools of water in the front yard caused by a major leak(s) in the water line encased in the attached garage slab. Angie responded right away with plumbing recommendations. We ultimately chose Major League Plumbing who came out the same day and made the assessment. Our house structure allowed them to bypass the leak(s) by rerouting the pipes to the first and second floors in one day thus saving us a ton of money in time, materials, and labor. Michael, the owner, was extremely pleasant and efficient. We certainly appreciate his creative solution and would definitely recommend the company and use them again for our plumbing needs."
