Recommended Customer Reviews

Streamline Plumbing replaced a sewer lateral for our rental property in Castro Valley three years ago. The owner Greg and his office manager April were great to deal with. They maintained excellent communication with us throughout the process. Their price was very competitive. Their crew was on site on time and completed the job early. They left a clean jobsite and were respectful of our tenants. We had a minor issue with some new concrete that they poured, but they addressed the problem very quickly and to our satisfaction. It's been three years and we have had no problems with our sewer line. I have recommended them to other friends and business associates.

Streamline replaced part of my sewer line so it would pass the required EBMUD inspection. And it did. But in doing so left me with a exterior waste pipe that now sits off by 15 degrees and looks like crap. I contacted them several times to come fix it and after 3 weeks the owner Greg calls me and leaves a voice mail of pathetic excuses of how and why it's supposed to be like that. It's not, it's just poor workmanship, to lazy to fix their mistake. Yeah my sewer passed inspection but I have to look at their crappy work every time I walk into my house.

Wow! My husband and I can't say enough good things about Streamline Plumbing. Throughout the Underground Trenchless replacement of our aged sewer system, The owners Greg and April and their expert crew were topnotch .
They provided a timely complementary estimate, in which Greg took the time to fully evaluate the complexities of the sewer system in the 4 plex.
They project was completed right on time and they took great care to be neat and clean with their work.
Greg worked with the City of Pleasanton to get all necessary permits to move the project along smoothly. His wife April was a pleasure to work with and coordinated the scheduling flawlessly.
We would highly recommend Streamline Plumbing to anyone who wants a large plumbing update done right!

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
