Recommended Customer Reviews

Thank you, Vincent, for making 2 trips to my home to do a quick camera inspection of the sewer lateral. To be clear, Vincent came out before the appointment and did the inspection. I wasn't notified initially, so I was skeptical/uncertain as to what happened. No offense, but when do service providers provide a service without telling you that it was done and you had no idea that it was happening before the appointment time?
Needless to say, he rolled up over again after listening to my concerns. He was transparent and allowed me to record the camera inspection. Also, he gave some very helpful insight on a drain pipe that we did have issues with months ago. OK, let's be clear... Sewer Master only works with sewers... not any other type of pipe, so I really appreciate his patience in dealing with our inexperience.

If you need an honest sewer guy to arrange your sewer test with EBMUD, hire Vincent at Sewer Master. He is totally honest and very knowledgeable.
We are so grateful for the job he did obtaining our certificate from EBMUD. Unfortunately, many sewer companies are treating the pressure test requirement as a way to pad costs and inflate the price to the homeowner. We wanted to sell our house with the certificate in place, not leave it for the new owner. We got 4 bids. The scope of work and price were vastly different. We chose Vincent at Sewer Master and are so grateful that we did.

VINCENT and the team at Sewer Master Bay Area are THE ONE to call!
We needed estimates to obtain an EBMUD PSL certification up against the deadline. Where other companies simply eyeballed the job and tossed out an estimate for full replacement (w/o even properly identifying the location of the existing lateral), Vincent conducted a thorough TV inspection and locate on the existing line, concluding it was not likely to need full replacement. He provided an accurate estimate for the needed work.
Vincent is straightforward, honest, an expert at his trade, and Sewer Master delivered on time exactly as promised - PSL certificate obtained in less than a week!
He went above and beyond for us in several ways, including adjusting the price proactively when slightly less work than initially anticipated was required.
We'll happily go right to Sewer Master for any future needs without messing around with other companies. Thanks to Vincent for the great service!

In short: Sewer Master is a fantastic, local contractor that specializes in the EBMUD private sewer lateral certification process. Vincent and his crew do great work, are responsive and easy to communicate with, and provide competitive pricing.
My project included the repair of a clean-out on my property, the repair of my private sewer lateral's connection to the City mainline, and a pressure test for EBMUD. I got six quotes from different contractors and ended up choosing Sewer Master because they demonstrated the best understanding of the scope with their detailed written proposal and reasonable bid.
I paid the deposit online via credit card, without additional fee, and Vincent had a crew out at my house doing work within a few days. The crew did a great job minimizing damage to the surrounding vegetation and left the work area spotless after every shift. The line passed the pressure test with no issues and they did a great job replacing all of the concrete pavement afterwards. Sewer Master coordinated all payments and inspections with EBMUD and I received my certificate a few days later.
I would definitely recommend Sewer Master to anyone who's home is in need of any type of sewer work. It can be a stressful and confusing process and having a reliable and transparent contractor is a life saver.

Vincent is clearly an Oakland veteran who deeply understands the intricacies of Oakland's sewer system. He was prompt, reliable, straightforward and a clear expert. Look no further!

Vincent Gaines the owner was very attentive to the issue of replacing my old sewer for a new one. He showed me on camera so I could see the reason why I was having plumbing issues. He dug up cement and replaced it nicely. He took a piece of my lawn up and was careful putting it back. His guys left my yard better than it was before. Very honest man.

I can't say enough good things about Vincent Gaines and his crew. We had a bad sewer back up (again!) and decided it was time to get the sewer lateral replaced. We had 4 people come by for estimates and knew even before we got any of the quotes that we wanted to work with Vincent. He took the most time to figure out what really needed to be done and we just felt good about trusting him. Communication was great throughout, the crew did a great job, the quote was competitive and I would recommend Sewer Master and Vincent to anyone.

We contacted Sewer Master to conduct an assessment of our Sewer Lateral. Vincent was responsive to our inquiry and scheduled an appointment to come to our home. He arrived promptly at our appointment time, completed a thorough assessment and outlined our options. We are very satisfied with the work completed and the ease in which Sewer Master assisted us with obtaining our Sewer Lateral Certification. I highly recommend Sewer Master!

Vincent and his team were super responsive and came out to do a sewer lateral inspection for me. He could always be reached and responded to all of my questions. He's fast, reliable and professional. He even helped me contact the city of Berkeley for the certificate! Thank you Vincent!

I got an email from this company that they are offering a free sewer lateral inspection and estimate repairs for listings. We scheduled an inspection that was supposedly conducted the next morning. Day later we emailed them to ask if the inspection is ready and they told us ""they are not bidding on the project"". We lost time and now need to find and schedule someone new.
VERY unprofessional.
