Diablo Rooter

Diablo Plumbing runs a family-owned operation out of Walnut Creek that handles plumbing work across the Bay Area. They take on repairs, installs, and emergency calls with same-day availability and 24/7 coverage for both homes and businesses. The outfit lists services for leaks, clogged drains, water heater problems, and bigger pipe jobs, and they keep a phone line open for scheduling at 925-261-6181.

Homeowners have called them for water heater repairs where the tech arrived on schedule and walked through the problem in detail. One job involved a quick fix on a household issue that the technician handled without extra visits, and another brought out a crew that dealt with an ongoing drain concern. Reviewers have noted sewage water left in a garage after a visit and heavy tool noise from night work at a commercial spot that carried into early morning hours.

The crew shows up for same-day requests and keeps emergency lines active around the clock, with some calls resulting in updates before arrival. Communication has drawn mixed notes, as some visits started without clear arrival times or ended without a heads-up on completion. Pricing came up as reasonable on one completed repair, and the service reaches residential and commercial spots throughout the Bay Area.

Google shows a 4 rating from 63 reviews with praise for certain technicians like Joe and Julie on water heater and repair calls. Other reviews flag late-night construction noise that breaks local rules and cases where tarps were not used to contain messes. DIRT Score 3.4 from reviews on Finds.

“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!”

“These guys are completely unprofessional and inconsiderate of local neighbors. I live on top of a chipotle that they're currently doing work for and they will use jack hammers, power drills, and other heavy construction tools ALL NIGHT. Completely disregarding the apartment building right above them and all of the noise that they are causing. THEY LITERALLY USED A JACKHAMMER AT 2 IN THE MORNING ON A THURSDAY NIGHT.. Not only is that rude and absurd, but it also violates city ordinance regarding construction past a certain time. This company's practices are completely ridiculous. I highly recommend you guys find someone else!!”

“These guys have terrible communication. They didn’t tell me when they were gonna get there properly. They didn’t tell me they were gonna leave. like they told me they were going to do. One of them was a really really not nice human being. I came outside and there was water that was sewage water everywhere all over my garage damaging my stuff. He didn’t even put a tarp up. I’ve had to mention it 1000 times for them to do that because they don’t go out of their way to do the little things like that. Avoid these guys if you can, they’re nothing but Mediocre”

“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”

“DO NOT GO TO THEM. THEY DO NOT CARE ABOUT NOISE AND WILL CONDUCT HEAVY CONSTRUCTION ALL NIGHT, REGARDLESS OF WHETHER OR NOT PEOPLE ARE TRYING TO SLEEP.”
