    This company is punctual, prompt, reliable and highly competent. I was very satisfied with their work. When the owner came out for an estimate, I asked a lot of questions, including how many people work for him and how are they trained. The answer was 40, and he trains them himself. On the appointed day, the owner showed up with several trucks and a dozen workers. They were very friendly, helpful in digging up and replanting my plants, and there was great teamwork. Well trained and competent people, who did not mind that I followed them around and constantly kept asking them what they were doing. I learned a lot in the process about the function of my sewer and watched how to put in a new lateral with wonderfully synchronistic team effort. The work was done within one day. The next day in the early morning a cleanup crew showed up and power washed the sidewalk and street, to eliminate all the marks. In the late morning another team came to put permanent asphalt on the street. I recommend this company highly and will use them in the future if the need arises. Thank you Greg Martin for running such a well-functioning company!

    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.

    Large, efficient crew to do the work in a day!

    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!

    Open trench goes 2/3 of the way across the street.

    Highly recommended. Streamline did a big sewer lateral replacement job for me in Berkeley (150 feet, including a five foot deep trench across the street to the main). It was done in two days, including pavement replacement. Craig Martin, the owner, and April in his office patiently answered all my questions in the bid phase. Two weeks after I accepted the bid five trucks and twelve men appeared at my door. It looked like the Normandy landing as some worked in the street and others fanned out around the house. The five trucks were carrying a whole array of specialized tools to detect buried pipe, fuse 12 foot lengths of pipe together, open the trench in the street and pressure test the final result. Later in the process dump trucks promptly appeared to remove dirt and fill the street trench with gravel. Everything was marked Streamline - no subcontracting, no scheduling problems. The workmen were clever and adept. The city inspector assured me they had done a good job. When they swept up and left at the end of the second day there was not a single loose end. With a smaller crew I'm sure this job could have taken a week.

    Great work!

    The team was on time, professional, and their work matched the estimate. They left our yard in good shape. We would hire Streamline again.

I called a civil standby officer to keep the tenant at bay, but his threats continued. Other contractors might have been intimidated. But Joel remained steadfast and finished the job by my deadline.

The technician, Salvador G. came early, on time. He called me to let me know he's on his way. He fixed the plumbing problem, the tenant was very happy with the work. Salvador called me to Let me know the work was finished, sent me pictures via email of before and after the Job.

We got bids on a "pex" replacement and when we told them theirs was too high the bid was magically lowered. We were the fools who took the lowest bid. What we thought was a "repiping" of our house turned out to be a "partial repiping." So the drip was fixed but a lot of old galvanized piping remains. And here's the bad news: the new pex piping was inadequately attached to the floor joists under the house and the installer removed many sections of furnace ducting to work down there and run the new piping. So we found that one of our heater registers had no heat/no attachment to the furnace duct! Hot air blowing into the crawl space.... So we have paid someone to reattach the piping and the ducts. And when the "new piping" was done I subscribed to the annual maintenance agreement. This is a total scam! No work is done under this agreement. It is only an opportunity for Albert Nahman "technicians" to try to up sell various filters and improvement systems. And the "inspector" missed the heating duct problem.... Avoid the big yellow truck! Do not let these guys into your house!
