"My HOA manager recommended Diablo Plumbing based on their past work at my property. Joe Sensi came out and fixed my issue quickly and professionally. He even gave me tips on how to fix the issue myself if it happens again. Very appreciative of Joe’s knowledgeability and friendliness, and the reasonable price for services.

"Once again we had Diablo Plumbing out to figure out why our water heater was not working, they were easy to work with on the phone and on time when they said they’d be here. Julie was very professional and sent updates before the tech arrived, Joe the technician went over and beyond with his explaining the issue. Thanks again for making this service call easy…jeff" says Jeff on Google
