Is trenchless sewer repair cheaper than digging?

Per foot, not always. HomeGuide prices lining at $90 to $250 a foot and bursting at $60 to $200, against $50 to $250 a foot for replacement overall. Trenchless can come out ahead once you count what digging destroys: driveway concrete, landscaping and the street patch. Get the restoration work priced in every quote before comparing.

How much can a plumber ask up front for a sewer repair in California?

For home improvement work, the down payment is capped at $1,000 or a tenth of the contract price, whichever is lower, with no exception for special-order materials. Later payments can't run ahead of the work done or materials delivered. Any job over $500 needs a written contract. A big upfront demand is a reason to walk away.

Who pays to fix the part of the sewer lateral under the street in Torrance?

The property owner. In Torrance the owner's pipe starts about 12 inches outside the building and ends at the public main, connection and all. Work past the property line also needs a Construction and Excavation Permit, so a repair under the street costs more in permits and street restoration than one in the yard.

Torrance Hydro Jet arranges a quote visit from an independent plumber when a camera run has found a break, a sag, roots through a joint or a collapsed section. Have the video ready if you have one. The quote depends on where the damage sits, how long the bad stretch is and whether it runs under the street.

Spot Repair of One Broken Section

When the camera shows one crack, one root-choked joint or one collapsed length, the fix is to dig at that spot, cut out the bad pipe and couple in new PVC. HomeGuide notes that a partial repair may cover only 1 to 15 feet, against about 40 feet for a full replacement. Angi puts sewer repair at $60 to $250 a linear foot. A spot repair only makes sense if the rest of the line looks sound on video.

Cured-in-Place Pipe Lining

Lining puts a soft, resin-coated tube into the old pipe, inflates it against the wall and lets it cure into a new pipe inside the old one, with no trench. The host pipe has to be cleaned first, and cast iron may need descaling before a liner can go in. HomeGuide's range is $90 to $250 a foot.

Pipe Bursting

Bursting forces a new pipe through the old one: a machine pushes the old pipe out of the way as the new line is fed in behind it. It needs a large pit at each end of the run, not a trench in between, and it replaces everything between the two pits. HomeGuide prices it at $60 to $200 a foot.

Full Lateral Replacement for Orangeburg or Collapsed Clay

Orangeburg, a tar-paper pipe, went into sewer connections from about 1940 to 1970, and the plant that made it closed in 1972. It starts to deform after about 30 years and gradually flattens, and drain-cleaning tools can damage it further. HomeGuide gives Orangeburg and clay a life of 30 to 60 years, against 50 to 100 for PVC and cast iron. The only way to know what's under a particular house is a camera run. If it shows soft, oval or flattened pipe, price a new PVC lateral rather than another cleaning.

Torrance Permits and Lateral Ownership for Sewer Repairs

Torrance puts the lateral on the property owner, starting roughly a foot outside the building wall and running to the public main, tie-in included. The city's sewer plan spells out that this means both the upper and lower lateral, and its sewer page lists blockages, breaks and root intrusion in the private part as the owner's problem. Which permit a repair needs depends on where the damage is:

Building to property line
A plumbing permit, issued as "Alter Building Sewer."
Property line to the main
A Construction and Excavation Permit for work in the public right-of-way.
A repair that crosses the line
Both permits.
Where to apply
Community Development's permit center (3031 Torrance Blvd; phone 310-618-5910) or the city's online permitting system. Walk-in hours on Wednesday run 8:00 AM to noon.
The plumber
The city wants a licensed plumber who also carries a Torrance city business license.

HomeGuide puts plumbing permits at $30 to $500 nationally. Ask whether the quote includes permit fees, inspections and restoring any concrete or asphalt.
