In northern New Jersey a full sewer line replacement usually runs $10,000 to $20,000, depending on depth and length of run. Repairing one bad section runs $3,000 to $8,000. Most of these jobs open the street to make the connection, which brings a road opening permit, traffic control and restoration with it. Done properly, the new pipe can last 30 to 40 years or more, as long as roots never find it.

The ranges exist so you can tell a serious bid from a fantasy. Anyone who quotes you a single flat number over the phone without seeing the property is guessing.

The three numbers

Work	Range	What it covers
Spot repair	$3,000 to $8,000	Digging up and fixing one bad section, such as root intrusion in a five foot section. Includes the plumbing, the materials and the digging.
Full lateral replacement	$10,000 to $20,000	Replacing the line from the house out to the main. Depth and length of run decide where in the range you land.
Trenchless lining	$80 to $250 a foot	Only for a pipe that still holds its round shape and has decent slope. It cannot fix a collapsed or badly deformed line.

Our ranges in northern New Jersey as of August 2026. Not a quote for your property. The full breakdown with what moves each one is on what this work costs.

What moves the price

Depth. The biggest factor. A deeper trench is wider and needs more shoring for the same length of pipe.
Length of run. The further the house sits from the main, the more there is to dig.
What is on top. Grass is cheap to restore. Concrete, pavers, mature landscaping and asphalt are not. If the line runs under your driveway, the driveway section comes up and goes back.
The road.Past the property line the job picks up a road opening permit, traffic control, and restoring the road to the town’s standard. This is the jump that surprises people. It can add thousands, and the township sets the rules, so it is the same for every contractor.
The pipe itself. Houses built from the 1940s to the early 1970s often have Orangeburg, a tar paper pipe that deforms as it fails. Once it flattens, lining is off the table.

Who owns the pipe from your house to the street

New Jersey has no statewide rule. The split is set by your municipality or your local sewerage authority, and it varies from town to town. The lateral is the run from the sewer main out to roughly the curb or property line. The house connection is the run from there to your building. Some towns hold the owner responsible for both, all the way out to the main. Others take the street side themselves.

Waterford Township is an example of the strict end. Its ordinance says property owners are required to keep clear, maintain and repair the sewer lateral from the sewer main to their house. If your town is written that way, the expensive part under the pavement is yours. Read the Waterford sewer ordinance.

Before you accept anybody’s quote, call your town’s sewer department and ask where their responsibility ends. Ask for it in writing or get the ordinance section number. It takes one phone call, and it is the difference between a yard job and a road job.

If the pipe is Orangeburg

Orangeburg is the one material that mostly removes the cheap options. It is wood pulp bound with coal tar pitch. It deforms into an egg shape as it soaks up moisture, and once it has lost its round shape there is nothing sound left to line. An Orangeburg line is almost always a replacement, so budget in the replacement range even if only one section looks bad on camera today. The rest of that pipe is the same age.

If your house dates to that era, read our guide to identifying Orangeburg pipe.

Repair, replace, or line it?

A camera inspection settles this, and it is worth doing before anyone digs. The question underneath it is simpler than it looks: is the problem this section, or is the problem this pipe?

Repair, when the pipe is fine and one spot is not

A collapsed piece of PVC, or root intrusion at a joint, in a line that is otherwise sound. That gets lined or dug up and repaired in one section, typically $3,000 to $8,000. The rest of the pipe has years left.

Replace, when the material itself is the problem

Orangeburg, cast iron, or anything that old. A spot repair will work on that one section. The trouble is that every other foot of the line is the same age and material, so the next failure is a schedule, not a risk.

Lining, where it fits

Trenchless lining runs roughly $80 to $250 a foot. It fits lines with good slope and a round shape. On a short residential run, the math often favors digging it once and being done for decades.

Plumber or excavator?

A clog, where the pipe itself is intact, goes to a plumber first. They can camera it, snake it and jet it. Often that is the whole fix and nobody digs anything.
A pipe that is broken, collapsed, root-intruded or deformed, below ground, is the dig. No jetter fixes a pipe that has lost its shape, and that is the work we do directly.

The camera tells you which one you have. The usual sequence is plumber first, camera, then a call to us if the picture shows broken pipe. We will not take a digging job that was really a clog.

What the job looks like

Most residential sewer replacements are one to two days, start to restored. The work runs dig, replace, inspect, backfill, restore. The backfill goes in compacted lifts so the trench does not sink next spring, and the yard goes back the way it was.

Common questions

What does it cost to replace a sewer line from the house to the street?

Typically $10,000 to $20,000 in our area, depending on depth and length of run. Most of these jobs mean opening the street to make the connection, and that brings a road opening permit, traffic control and restoration with it.

Am I responsible for the sewer pipe under the street?

It depends on your town, because New Jersey has no statewide rule. Some ordinances make the owner responsible from the sewer main all the way to the building. Others stop the owner's responsibility at the curb line or a cleanout near the property line. Ask your sewer department where their responsibility ends before you accept a quote that includes the street.

Should I repair the sewer line or replace the whole thing?

Ask whether the problem is one section or the whole pipe. Root intrusion or one collapsed piece of PVC in an otherwise sound line is a repair, typically $3,000 to $8,000 for a five foot section. If the line is Orangeburg, the material itself is what is failing, and the rest of the run is the same age. Repairing one section of that is a small bandage on a bigger problem.

Can a sewer line be replaced without digging up the yard?

Sometimes. Lining works on a pipe that still holds its round shape and has decent slope. It does not work on a collapsed or deformed line, which rules it out for most failed Orangeburg. Directional boring is the other way to avoid an open trench, and our guide to replacing a line under a driveway covers when that works.

How long does the job take?

Most residential sewer replacements are one to two days, start to restored. A run under a road takes longer, because the permit, traffic control and road restoration all have their own schedule.
