Some Very Happy Customers

Great companies create exceptional customer experiences. We’ve heard from many Bay Area consumers who are glad they chose a Diamond Certified company. Here’s some of what they’ve had to say:

Angelo Romanini was impressed by the honesty and integrity of Smart Plumbers, Inc. When he called the company for help with a leaky faucet, the technician explained how Angelo could fix it himself. “It was an easy repair,” he writes, “but if Smart Plumbers had sent someone over and charged me a lot of money, I wouldn’t have known any better!”
