When I last used Cupertino Plumbing, they came out to clean the drains from my washer. The next day my machine started acting up, and I found out that they never turned the water back on. So I had to get behind the machine as best I could, to turn it back on. The worker that came out was training a new guy, so I understand the mishap. That was my only issue, as they did a good job, and they've always been great. During the time that I've been using Cupertino, they've been honest, helpful, and saved me money as best they could. So far, aside from the minor issue, everything has gone well, and I might possibly use them again.
