Cupertino Plumbing did great work. I was having a plumbing issue and called them. They were responsive and easy to schedule with. The plumber came on time and worked efficiently to resolve the issue in a timely manner. He was professional, polite, and pleasant. I liked that he was clear about what he was going to do. He resolved the issue and everything has been working properly since. The only issue I had was that the cost was pretty high and I hoped it would have been lower. I would probably use a lower-cost plumber next time, but I had an overall good experience and would recommend them.
