Trenchless sewer replacement in San Jose uses pipe bursting, which pulls new HDPE pipe through the old one, or cured-in-place lining, which forms a new pipe inside it; published 2026 figures put a San Jose lateral at roughly $5,500 to $14,000 by bursting versus $9,000 to $22,000 open cut.

How trenchless replacement works
A conventional sewer replacement digs a trench from the house to the street. Trenchless methods need an entry pit near the house and an exit at the connection, and the new pipe goes in underground between them. Lawns, driveways, trees and hardscape stay mostly intact.
Not every line qualifies. A collapsed section, a severe belly or a line with too many bends may still need excavation at those points. The camera inspection decides which method fits your lateral.

What trenchless replacement costs in San Jose
The published figures below are for a typical San Jose lateral; the camera footage and the route decide where yours falls.

- Length of the lateral. longer runs need more pipe and pull force
- Method. bursting and lining price differently
- Depth. deeper pits take more excavation
- Sidewalk crossing. encroachment permit and concrete restoration
- Condition of the host pipe. collapsed sections may need spot excavation
- Cleanout work. adding a two-way cleanout at the house

Pipe bursting
Pipe bursting pulls a cone-shaped bursting head through the old pipe, fracturing it outward while a new high-density polyethylene pipe follows directly behind. The new line is joint-free and usually the same size or one size larger than the old one. It suits clay and cast iron laterals that are cracked and root-invaded but still continuous. We dig a pit at each end, fuse the new pipe on site, pull it through with a hydraulic unit, and reconnect at the cleanout and the city side.
Cured-in-place lining
Lining inserts a resin-saturated felt tube into the cleaned host pipe, inflates it, and cures it in place, forming a new pipe inside the old one. It needs less digging than bursting, sometimes only the existing cleanout, and suits lines that are cracked but still hold their shape. It reduces the inside diameter slightly and depends on a thoroughly cleaned wall, so we jet and camera before lining, and camera again after curing to confirm the liner has bonded and the branch connections are reopened.
Sidewalk crossing and encroachment permits
Many San Jose laterals cross the public sidewalk before reaching the main, and work in that right-of-way needs an encroachment permit from the city in addition to the plumbing permit. We pull both, plan pits to avoid cutting sidewalk where possible, and restore any concrete to city standard when cutting cannot be avoided. The inspection at the end covers both the pipe and the right-of-way restoration, so we schedule it once the surface is finished and the concrete has been restored to the city's standard.
Local context
Slab tracts, lateral rules and where trenchless helps most
Point-of-sale rules here mean a sewer lateral must pass video and pressure tests before a house changes hands, and a lateral crossing the sidewalk needs a right-of-way encroachment permit. Trenchless work pays off most where digging is costly: the slab-on-grade tracts built across Berryessa, Evergreen and Cambrian Park in the 1960s and early 1970s often have mature landscaping, driveways and hardscape over the line that a trench would destroy, and restoring those surfaces is a large share of an open-cut bill.

Timing
How long you are without the sewer
Most trenchless lateral replacements finish in one to two days, and household drains are usually out of use only while the new pipe is being connected.
Permits and the final inspection add calendar time before and after, especially when the city's right-of-way permit is involved.
