Recommended Customer Reviews

Terrible experience. Had a app for a quote to replace lateral. Called the ceo multiple time and never got a quote. I finally got a hold of someone and they said they could not do the job because of a new paved road on my street. They say that is why they never gave me a quote!! Hello a call would have been great to say we cannot do the job sorry. How can you blame a potential customer for your mistake!! Terrible service will never recommend to anyone.

I've read their reviews and seen their trucks around town. All looked good. My sewer was backing up out of the clean out. I had a plumber snake the sewer and run a camera. He said it separated at the tee. I called and Cody came out promptly. He attempted to run his camera down and couldn't get it. He looked at my second clean out but said he couldn't get the cap off cuz he didn't have the right tool. (My hubby had the cap off just two months ago). He said he couldn't run the camera. Also said I would need a two way clean out. At the time I didn't know but I do have a two way. He said he was going to send me the estimate. I have yet to see and response. I've left messages but had no responses. How do u replace a lateral without seeing what the issue is? Roots, separation?? Oh well guess they didn't want the job. Wasted my time and his

Moving to Castro Valley has a ""draw back"", as the city has implemented ordinance that any housing transaction resulting in new ownership will require that house to have a new sewer lateral and sewer clean-outs (as of 2019). Overall, it does benefit and protect your investment (your new home), since sewer laterals last about 30 years or so and needs replacing if older than that as you run the risk of the lateral leaking or breaking and all that waste water will go into the ground. The clean-outs will protect your house from any clogs in the lateral or city sewer line backing up waste back into your house.
Streamline Plumbing gave us a quick estimate of the costs, and came out to do a quick assessment of what we needed. Since the house we purchased didn't have any clean-outs, it was a given that the lateral was old and needed replacing. With the new sewer lateral and clean-outs, it came out to being $6,800, which was a few hundred less than other places I got quotes from. April whom I was in contact with throughout this whole process handled everything from booking the appointment/time to have the crew come out to do the work to all the required permits and paperwork. Very efficient and the actual work on the lateral and clean-outs took a day (was ~7.5 hours, as the crew was here from 7:30am-3pm including city inspector doing the inspection). The replacement of the cement where the clean-outs were placed was done pretty well, and everything was cleaned (area where they needed to dig up to access the sewer lateral) and replaced properly.
I recommend Streamline to anyone in Castro Valley or around neighboring cities that need sewer lateral and clean-out work, as they know what they are doing in an area that many of us new homeowners do not have any experience in. Before this, I didn't even know what sewer laterals and clean-outs were. Not knowing what something is and depending on a company to help you through this process requires a lot of trust, and with what I experienced from Streamline I definitely have my 110% trust in them!

I called a few places to figure out the process for examining the sewer lateral and fixing it to pass an inspection. Streamline was the only one that said that they'd send a rep over right away to send a camera up the line to see what work needs top be done (all others charged for this and said it might take a while).
After the camera work, they gave me a reasonable estimate and completed the job on budget and quickly. They answered all my questions and cleaned up well. What more could you ask for?

My experience working with streamline was absolutely fantastic. They were very clear about the scope of the project, give me a detailed estimate, told me how the work could affect my neighbors, and overall very professional all the way around. I gave April and her team two thumbs up... You will not be disappointed with this company. thank you

Replaced our sewer lateral in Castro Valley. They were on time, efficient and professional. Great work and a very easy experience. They were able replace the sewer lateral without destroying our retaining wall too, which was a huge plus! A few other quotes we had said they would need to go through the retaining wall and would only repair it with cement and not the decorative stones we have. Those quotes, too, said that their quote may increase depending on that retaining wall work. Streamline was able to do it and pass the city inspection without any damage to the wall at all. Would highly recommend! Also, very reasonable price!

After consulting with several companies over replacing my sewer line I decided to go with Streamline and ended up thoroughly pleased with their work and professionalism.
Reading reviews it's evident that there aren't many competent, or ethical, companies operating in the area.
My circumstances were unique in that there were a couple of high retaining walls to circumvent and a main connector in the street that was around 25 feet below grade. No small task and one company honestly told me they weren't qualified to do the work.
Greg, the owner, was honest, upfront, professional and clear with the work to be done and I hired him on the spot. Literally a few days later he had a full crew out doing the work efficiently and in a very well planned operation, all trenchless. He had told me specifically where cleanouts needed to be placed and all the work done in one day, and appropriately clean afterwards too.
All the permits and inspections were handled well and in the end I was extremely pleased with the work and dealing with the company.
I highly recommend Streamline.

Another great experience here with Streamline repairing a sewer lateral in Berkeley. Very fair price, fast work.

I recently had Streamline replace my sewer lateral at a home in Montclair. This is the second project they have completed for me over the past 7 years, at two different properies. Here are the things I really like:
The owner came out personally and bids the project.
They specialize in sewer laterals, and do them every day.
Price was very fair and affordable.
They had all underground utilities surveyed in advance.
They pulled a permit for the work (City of Oakland) and also had EMBUD inspect and certify their work (20 year cert.).
They showed up on time, exactly as scheduled, with 2 crews and 3 trucks.
They completed the work neatly in one day, including concrete and asphalt patching.
the final bill was exactly as quoted, with no add on costs.
April (in the office) is very helpful, professional and sweet as sugar!

Everything was perfect and timely (bidding, work, billing) with sewer lateral replacement.
