Recommended Customer Reviews

Update: work was completed on time as scheduled. Certificate received promptly. I'm giving 5 stars even with the bumpy start which could have been better communicated with the customer as to the delay in getting out to the property timely to conduct an estimate as indicated.

Our septic system finally failed and we needed both a sewer lateral installed and an abandonment of the septic tank. Greg, the owner, came out and did a comprehensive evaluation of the site. He took precise measurements, evaluated the potential sewer connection with a pipe inspection camera, and noted potential issues with underground gas and water lines. Two other companies that gave quotes only did a casual walk around. We ultimately chose Streamline Plumbing. Not disappointed. The streamline crew showed up on time and completed the project in two days including inspections. They worked carefully to avoid damage and did a fantastic job restoring the site to its original condition. I would highly recommend them. And their quote was substantially lower than the competition and seemed perfectly matched to the amount of work involved.

Our HOA was required to be compliant with EBMUD and I had quite a few plumbing companies come out to assess and provide estimates to me. over the course of several months, I have dealt with companies who came out and never heard from again, other companies who didn't even assess and just tell me I needed a trench less sewer line, and others who didn't run a camera and just provided an astronomical estimate.
After careful consideration, we settled on Streamline. They certainly wasn't the cheapest estimate but at the same token, they were not the highest. However, I liked the fact that they were professional and on time for the estimate. Greg came out and assess the situation carefully with a camera and looked around the property thoroughly. He provided me with two options to either try and run issues as is or provide a brand new sewer lateral line. Considering that we have had the same sewer lateral since they built these units, we opted to be safe and go with a brand new line.
They were quick and got the work done within 3 days, waited for the EBMUD person to come and test the lines and sent us a certificate.
Then, one and a half months later, we had a backup. So, I called Streamline to see if it was a problem with the sewer lateral and Greg came out the same day to assess the issue. Turns out, it wasn't the sewer lateral but rather someone in the complex flushing things that shouldn't be flushed. I just appreciated Greg coming out to assess it so quickly. That is professionalism!
I highly recommend Streamline Plumbing if you want thing done quickly and professionally!

It was a pleasure working with April from Streamline Plumbing on my Oakland sidewalk. We found out that we needed to get a sidewalk certification when we were ready to sell our property. I had to call around several places, and after reading reviews for Streamline, I decided to work with them. Honestly, they made everything so smooth. Sent someone to inspect it, interacted with the City on my behalf and got the work completed as promised. I was able to close on the property in good time. Thanks again for all your help.

You know how I know he doesn't call? Because he would rather lose business than negotiate. Greg, TBH...you must have felt like you were inconvenienced because you were so confident that during Covid you thought your competition wasn't going to make it, giving you a false feeling of strength. I found a company in Concord that did it for $2k less than you and had real time updates on the job during the day and profiles about the journeymen that arrived at my home and did the work. Didn't feel rush nor inconvenienced by them. Too bad for you, I referred your competitors twice and got them two more jobs, which could have been yours. I'm real because, who else would have this kind of detail on a job bid? Good luck G. You're going to need it...or simply retire.

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
