After a quick Google search for plumbers near me, I chose Nolasco for their excellent reviews and quick response to emergencies. True to the reviews, they came within 1 hour after calling them. Francisco was very professional and friendly. He came up with a great long term solution to my plumbing problem, not just a quick fix. The quote was a bit higher than expected.

Jeffrey, thank you so much for taking the time to share your experience! We know how stressful it can be to have a broken pipe and suddenly be without water, so we’re glad our team was able to respond quickly and get Francisco out to your home within the hour.
We especially appreciate you recognizing Francisco’s professionalism and his focus on providing a long-term solution rather than simply making a quick repair. We always want our customers to feel confident that the work is done right and built to last.
Thank you for trusting Nolasco Plumbing during an emergency and for your honest feedback. We truly appreciate your business and your 5-star review!

Since my house was renovated and ADU was built then; I had Nolasco plumbing did the entire work and maintained using this company since then. Yearly, I had them fo preventive maintainance and so far had no issues with our plumbing. My recent service was done by Luigi , who is pleasant / professional.. I was just a bit surprised with the price of the service compare to last year while I have supplied the parts for my RO system; my invoice was almost 75% higher. I understand the cost of everything nowadays but knowing that I had been a consistent customer , I would have not expected this much of price increase .. something that I may have to consider now ...

Luigi was the plumber sent to fix our issue with our Navien Tankless Hot water Heater. He turned out to be a great representative for this company. He was courteous, patient, professional and very knowledgeable about our particular model and quickly figured out why our unit stopped heating the water. Luigi had our unit up and running by the next morning with the appropriate part and taught me how to clean the air filter on the unit to help prevent the problem that occurred with our heater. I highly recommend Nolasco in general and Luigi in particular for their service.
