Customers say: Super punctual

"The plumbing technicians came out as promised to assess the leak. They were both very courteous and kind and assessed the damage. I am giving three stars because they estimated the cost to be almost 250% higher than what the actual cost was to fix the issue. I am sure there are customers out there that would just accept any bid however, please get multiple beds for these projects, especially when working with this company as they will inflate the cost to take advantage of the situation. I ended up only paying for the $79 estimate."

"We did not have a go-to plumber, nor did our neighbors, so we asked Angi. They recommended Steven Bailey, and it was the right choice. The job was a simple replacement of a traditional bathroom sink drain plug with a pop-up that will catch hair and, we hope, prevent future clogs. Steven was responsive, knowledgeable, and friendly, and he explained the options clearly and simply. He is an honest and skilled tradesman, and charged the minimum for the job, which was less than other quotes. Now we have a go-to plumber, and you can too!"

"We needed a building cleanout installed as a requirement for our remodeling project. Cornelio was very thorough in investigating what were the requirements for the inspection. He installed a dual cleanout following all the requirements which will help us in case of any backups in the future. He was very transparent about the cost, and finished the installation on the following day. Highly recommend him for any plumbing issues."

"We had a backup in the kitchen sink that needed to be cleared up. Robert assessed the issue, and gave a more than fair quote. He even suggested , if need be, he'd crawl under the house and find the issue. I appreciated the obvious fact Robert wanted to make sure he left with a happy customer. He repaired and we are happy =) 5 STARS !!!!! "

FAQs for sewer main install, replace or repair projects in San Francisco, 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.
