I called in Cupertino Plumbing to deal with a drainage issue and I wasn't very satisfied with their work. The kitchen sink was blocked and their guy did the work; he also cut out some pipe, which, I wasn't convinced, was necessary. It seemed initially to have fixed the issue, but then they had to come back the next day as the leak began again. It also took longer than I thought it was necessary, because of the pipe issue: he took an hour and a half for something that should have been done in half an hour. Their pricing was also unsatisfactory. They charge by the hour with a minimum of an hour, but the hour begins fifteen minutes prior to the job. Overall, I'm not happy with them.
