DIAMOND PLUMBING AND ROOTER

We have used this family-run wonderful!! company (Hugo. Alphonso, Angel & Hugo, Jr.) for the past 6 years … always on-time; never try to push for expensive solutions: always fix the problem (usually pesky tree roots in the pipes); always enjoyable to interact with. UP-DATED SEPTEMBER 2025: Did a large job for us today ... still deserve 5 Stars!!! Nice people to have in your home.

Hugo is a fantastic plumber. He is very knowledgeable and truly knows his craft. We have worked with Hugo for many years now and he always comes through. He not only cares about his customers, but uses his expertise to help them understand the scope of work and process involved. If you’re looking for a skilled plumber with affordable rates in Contra Costa County, look no further!

This company is amazing! Hugo went above and beyond my expectations and helped me in any situation and every way, and gave me the best results. He always provides the best satisfaction and will give his time to help explain the situation. I appreciate the honest and hard work from him and the company!

My kitchen sink was really clogged and a friend recommended Diamond plumbing. Got an appointment quick. They did a great job and the plumber explained everything to me before, during and after!! Clog is gone.

Diamond Plumbing has been to my house tending to these old AF pipes for 2 years now, each time diagnosing the problem efficiently and taking care of the issue with relevant recommendations and options... Everytime they come in have peace of mind - even with the bigger job they've just come out to assess and bid. I highly recommend these guys as they are on time, super friendly, and worth every penny you spend. They are fairly priced and small business / family owned and you can tell they care about their work. Highly recommend.
