Cupertino Plumbing did a lot of work for us last year, on multiple occasions, and they were just wonderful. They undertook plumbing work in that they replaced the copper piping, and after that, we have called them up on other issues. Whenever we have reached out with any problem, they have responded very promptly. They also have good follow up, which I appreciate. Overall, it's been a very good experience working with them, and I'm very satisfied.They are very good at what they do and they are conscientious about their work. They offer compteitive pricing, especially given the quality of their work, but they are also flexible, which is great.
