"So far so good. Snaking of kitchen sink with very old pipes. Hopefully snake did not poke pipes. Only time will tell. Keeping fingers crossed. They did a good job explaining and triple checked for leaks before they left. Of course they tried to upsell and gave us a metal trap they did not quote us upfront for. We would have chosen it over plastic, but price difference would need to be cleared upfront. That's the only negative. Otherwise, thus far we are very happy with the result. Thank you for coming on such short notice and on time! Super appreciated. 4.5-5 stars."

Above all, we are watchful of our customers' interests and make their concerns the basis of our business. Our customer's safety is extremely important, which is why all of our technicians are fully trained, background checked, and drug tested.

"A troublesome shower drain was resolved quickly by Oak Plumbing. I want to recognize Niles, Harris, Jessy, and Amari for their great work. Niles inspected the crawlspace, measured every line, and gave me a fair quote based on my home’s actual layout. Harris cleared space for the new pipes, sketched the floor plan, and confirmed materials. Jessy and Amari replaced all horizontal drain lines—including the garage sink, washer, kitchen sink, two toilets, shower, and two sinks—in tough conditions under the house. This started after another company gave me a flat-fee quote based on “two bathrooms.” Oak Plumbing’s quote was more detailed and more accurate for my 1950s home with 1.5 baths and mixed old materials. Their bid was over 10% better, and I left a deposit that day. I’m grateful for how quickly they solved the problem, especially days before Thanksgiving. As a single mother who relies on Angie’s List, this experience fully met expectations. I highly recommend Oak Plumbing."

Albert Nahman Services was founded in 1981 and has been serving Berkeley, CA and it surrounding areas in all their plumbing and HVAC needs. Each of our technicians went through rigorous training so we can guarantee that you will be receiving the proper service. We are also insured and supply a warranty for our parts for five years and up to twenty years on an re-piping or sewer replacement. Call us now to make your appointment!

"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."

Bonney Plumbing, Sewer, Electrical, Heating and Air, has been your local, reliable service company since 1978. As an A+ rated member of the Better Business Bureau, we have worked hard to build our reputation by providing you with top notch technicians, superior products and exceptional customer service. We have serviced thousands upon thousands of satisfied, loyal customers and are so pleased to earn your referrals. You can count on Bonney for quick, reliable service and repair for your plumbing, electrical, heating and air conditioning needs.

"For starters, most of the people that came out to do the actual work were fine. My issue is that I have been waiting since the beginning of 2024 for a response on being overcharged for a duct run that was never completed as part of a nearly $20,000 project, despite several emails, phone calls, notes left on the account, etc. This is even including talking to someone on the phone who still calls me to set up yearly inspections as part of our Bonney Club membership. Not only that, but we have recently found evidence of mice in the house and in looking around the HVAC closet (which is within the conditioned living area and where mice have been) I was surprised to see that they left the ceiling of that closet wide open to the unconditioned attic space. No wire mesh (as was there before with insulation on top), no sheet metal (which was liberally used everywhere else, even to patch a drywall hole instead of using drywall), and certainly no insulation to replace what was there previously."

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