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. I heartily recommend Diablo Plumbing and will definitely call them for future plumbing concerns!
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
I have a sudden leak, and Diablo Plumbing was able to arrange emergency service the same day! The technician Joe Sensi is very professional, he provided a work around solution which is better than I thought originally. I highly recommend the Diablo plumbing if you have similar needs!
$250/hr minimum 2 hours. Plumber was here for exactly an hour. Ran a probe to see the sewer situation. There are roots as I suspected. Packed up his stuff and I was $500 poorer and my sewer is still having problems. They get your credit card on file before they will schedule an appointment.
Sean was wonderful. Though he arrived later than expected, that was not his fault for the prior job running late, and he notified me appropriately. He went above and beyond to make sure our initial problem was solved but also that our toilet was properly reinstalled and sealed so that it would perform better for the long run. It wasn’t just a rush repair job. He took the time to explain things to me and answer questions.
