"Jess helped us out with the huge job of replacing the entire sewer main pipe from under our house to the sidewalk given that our old cast iron pipes were corroded and kept getting blocked by roots. This was a 3 day job involving a multiple person team. We went with Jess given that his estimate seemed fair and beat out other competitors. The work ended up being more labor intensive than anticipated, as digging to the city sewer line, which should have taken hours, ended up taking a day and a half due to unseen gnarled roots and cement in the soil. Despite this, Jess and his team worked diligently, showed up when they said they would, and finished on time. They were courteous, professional, and very hard working. I will not hesitate to contact Jess for our future plumbing needs. Photo shows old pipe vs new pipe."

"Glenn and Josh are great guys. We had an emergency with Sewer blockage and they were at our house within an hour on a Friday evening. They cleaned it and also pointed out that we had old cast iron pipes which had cracks. Subsequently, we engaged them to replace all our sewer lines. The work was done within 3 - 4 days and they kept us up to speed on every aspect. The work was excellent (and they showed pictures to prove it). We would hire them for any of our plumbing needs and highly recommend them!!"

"Leo did a very extensive plumbing repair that required digging through my bathroom floor and replacing a huge pipe to the outside. He also prepared and installed piping and fixtures for a bathroom remodel. Always showed up when he said he would and had a great crew. Cleaned up as well. Would highly recommend. "

"Victoria Cedillo's team (Lead: Victoria. Team: Victor, Ruben, Richard, Pedro, and I am sorry if I missed anyone...) from Mike Counsil Plumbing did a wonderful job with our main line sewer and installing new sewer lines! Victoria's manager, Glenn, is very nice and patient. He provides guidance to Victoria's team to diagnose our sewer lines, provide recommendations and detail estimation options to us. We feel comfortable working with Glenn and Victoria during this job, and I have learned a lot regarding proper sewer lines and water lines connections. Victoria also took me into our crawl space and showed me the new sewer line at the last phase of the job. Victoria and her team are really professional and they've provided excellent customer service experience! For all the jobs they have completed, Victoria will provide photos and let us know what the current status of the job each day. Victoria is very considerate and she makes sure that we are able to use kitchen and bathroom at the end of the day (They will temporary connect the lines), and we really appreciate that! They also make sure the working areas are cleaned and covered up properly each day (if there is a wall opened) since there are rodents from our neighbors’ backyard. Mike Counsil Plumbing and Victoria’s team is knowledgeable with the city laws, proper line connections, and permit requirement. I was surprised to see a plumbing company that has their own work inspector (In this case, Dan B., was the one who came to my house for the final inspection. Thank you Dan!) to make sure all the works are according to code and it was done correctly. The works that were done at my house require city permits. Victoria makes sure we feel comfortable with the city inspection and she was present at the inspection. The company representatives such as Sabrina and Marissa are very friendly and easy to talk to. Comparing to other plumbing company, their price may not be the cheapest, but I can really see the quality in their work (compare to another plumbing company we hired years ago…). I highly recommend Mike Counsil Plumbing because I can trust their work and truly see the quality! Thank you, Victoria and your team for all the hard work! =)"

"This contractor performed the service efficiently, and provided the analysis and options for the sewer line. I felt he was honest with the options and did not try to sell additional services that were not warranted, in my opinion."

"When a pipe burst in our garage, we were pretty stressed trying to figure out what to do. Ron came out right away, shut everything off, and replaced the section of pipe that broke. He worked quickly but also took the time to explain what had happened and how to avoid it in the future. Really grateful for how calm and professional he was in a stressful situation. "

"Only fair in not having parts handy for immediate repair and having only an apprentice technician available for emergency repair of leaking water line. Then was late for a stated window of repair appointment and had to be called back to ensure the full functioning of the hot water line. Did not communicate clearly between estimator and repairing technician about the extent of repair and ensuring full functioning once done. Otherwise, was courteous and professional, and quite knowledgeable. Quick to point out other possible plumbing deficiencies which I must consider."

"Had leak overnight under BR sink and Chandler was 1st responder. Came out very quickly to repair/repair. Upon checking on leak evidence under house, found evidence of sewage &; water leakage/pipe corrosion &; we scheduled that repair for next day (different men). Job completed. Told owner that I want invoice detailing findings and work done, but all I received was e-receipts of totals I payed, ($220/$2500/$6000). He said he would send me either via email or hard copy by mail. I need for my house files. I am still waiting...but haven't contacted Ishmael Chandler since the 5/22-23/2023 job. Comment on personnel: Victor - great worker (fixed leakage). Mario and ? - Mario physically very dirty at 9a.m.) but very nice. Other man-fine. Both men very hard workers! Mario left quite a mess behind in my bathroom for me to clean up (toilet area from seal replacement)."

FAQs for sewer main install, replace or repair projects in Portola Valley, CA

When installing a sewer line, you should consider extra costs like tree removal, driveway repairs, or patio resurfacing. Hiring a professional plumber is essential, and you may need additional specialists if landscaping or heavy excavation is involved. Addressing these potential extras up front helps ensure accurate budgeting and prevents sudden cost overruns.

To calculate the length of sewer piping you need, measure the distance from your house to the main sewer line, adding the depth of the city main to this distance. Be sure to account for any obstacles like tree roots or utility lines that may require additional piping.

City sewer lines are installed at a lower elevation to prevent unwanted backflow and water damage. This lower positioning ensures enhanced performance and long-term safety, meeting all technical and safety standards.

With trenchless methods, a plumber inserts a smaller pipe within the existing plumbing, avoiding full excavation. It can be more cost-effective and less disruptive than traditional methods, but it's not suitable for all homes.

Yes, you must secure permission from your local water authority before connecting to a public sewer line. This approval ensures your connection meets all regulatory requirements.

Sewer lines are buried between 18 inches and 8 feet deep, with most systems placed between 18 and 30 inches. In colder regions, pipes are set deeper to remain below the frost line.
