I had a good experience with Cupertino Plumbing. They were responsive and easy to schedule with. The technician arrived on time and worked efficiently to complete the installation of a water heater in a timely manner. He was professional, courteous, and pleasant to work with. The installation process went smoothly and was without complication. The only minor gripe I had was that they quoted me the price for the whole package, but never gave me a breakdown of the pricing of the unit that turned out to be relatively expensive. Other than that, I had no problems with the service and am happy with how everything turned out. I recommend Cupertino Plumbing and will use them again in the future if I need to.
