I have been working CUPERTINO PLUMBING for about a year and a half now. I have been happy with their work taking care of a rental house I have. I have found their workmen competent and professional. While their prices may be a little high, they are easy to get a hold of and are close by, making them worth it. I did just have one problem with getting a response from the estimators for a couple of days, but other than that they have been great.
