Sewer Line Replacement Cost (2026) — Typical US Range

Replacing an existing main sewer line on a US single-family house — the lateral from the house to the connection near the property line, about 50 to 80 feet, in a yard a machine can reach — often clusters around $4,000–$15,000. That is the typical sewer line replacement cost, and the typical cost to replace a main sewer line, for that length. Installed work on a run long enough to carry the crew is typically about $50–$250 per foot. The wider national spread, about $1,500–$30,000, covers a small accessible spot repair at the low end and a longer line, a deep trench, trenchless work, or a real driveway and landscape restore at the high end. A line much longer than 100 feet, a full driveway replacement, or a house tying into a city main for the first time can clear that spread. These are typical planning ranges, not a survey and not a quote.

This page is a replacement of a sewer lateral the house already has. A new house that has never had a sewer, a septic tank and drain field, and a conversion from septic to a city main are different projects. Interior fixture drains in a bathroom remodel or a kitchen remodel are branches. They are not this line. A water heater or a tankless water heater does not touch the sewer lateral.

The pipe price is not the job. A stick of PVC can look cheap by the foot. The bid is the locate, the permit, the digging or the trenchless pits, the connection, the backfill, and whatever surface you open to get there. Length is the measurement. A deep line under a driveway and a shallow line across an open lawn are not the same foot. Price the line a camera has seen, not a rate from a forum.

The rows below are ways to read one job. They are not added together. The per-foot rows are installed prices for that method on a full replacement long enough that the crew is not the whole bid: the new pipe, ordinary backfill on a dig, and the pits or the access a trenchless method needs. They leave out a new driveway, a finished landscape, and a cleanout that was never there. The length rows are a full replacement at a common mix of those methods, in an ordinary yard. Use the spot-repair row when the camera shows one defect. Use an add-on row only when that line is actually extra.

Scope	Typical planning range
Traditional dig, per foot	$50–$150
Trenchless pipe bursting, per foot	$70–$200
Pipe lining (CIPP), per foot	$80–$250
About 25 feet, full replacement	$3,000–$7,500
About 50 feet, full replacement	$4,000–$12,500
About 80 feet, full replacement	$4,000–$15,000
About 100 feet, full replacement	$7,500–$22,000
Spot repair, one accessible break	$1,500–$4,500
Full replacement, about 50–80 feet	$4,000–$15,000
Camera inspection	$200–$600
Permit, when the bid leaves the city fee out	$150–$600
Landscaping restore along the trench	$500–$2,500
Driveway or sidewalk restore	$1,500–$6,000
Cleanout install	$500–$1,500

Traditional dig, an open trench, is typically $50–$150 per foot when the yard is open, the line is not unusually deep, and the crew can slope the hole safely. The low end is a shallow run in easy soil in a lower-cost area. The high end is deeper, wet, or dug by hand because a machine cannot reach. Ordinary soil back in the trench is in that rate. Seed, sod, a fence put back, and pavement are not.

Trenchless pipe bursting is typically $70–$200 per foot. The crew pulls a new pipe through the path of the old one, usually from a pit at each end, and the old pipe is split out of the way. The yard between the pits stays put. Bursting is a replacement: the new pipe is the line. It needs room for the pits and a path a burst can pass.

Pipe lining, often called CIPP, is typically $80–$250 per foot. A liner is inverted or pulled into the host pipe and cured in place. The old pipe stays as the shell. Lining needs a host that still has a path through it. A fully collapsed section, a large offset, or a pipe that has gone soft usually cannot take a liner. Those three method rates are the $50–$250 per foot band. Ask which method the foot is. A dig price and a lining price are not the same bid.

About 25 feet is $3,000–$7,500, not a straight $1,250. Twenty-five times $50 misses the trip, the permit, and the connection, which do not shrink when the footage does. The top of that row, $7,500, is $300 a foot, above the $250 lining ceiling, because a short trenchless job still needs access at both ends. About 50 feet is $4,000–$12,500. Fifty times $80 is the floor of that row. Fifty times $250 is the top. Fifty times $50 is $2,500, a shallow open-yard dig, and that number sits under the typical band, inside the wider spread. It is not the common 50-foot replacement.

About 80 feet is $4,000–$15,000, the typical band. Eighty times $50 is the floor. The top of the row is about $190 a foot, not the $250 lining ceiling. Eighty times $250 is $20,000, which leaves the row and still sits inside the wider spread. About 100 feet is $7,500–$22,000. A very easy 100-foot dig can land nearer $5,000–$7,500 and still touch the typical band. The same 100 feet at a high trenchless rate, or with a driveway cut, is how the row reaches $22,000 and how a stacked restore can approach $30,000. Use the length row or the per-foot row. Adding them double-counts the pipe.

A spot repair of one accessible break, a few feet of pipe in an open yard, is typically $1,500–$4,500. That is the sewer line repair cost when the rest of the camera run is sound. The floor of the wider spread, near $1,500, is that kind of hole. It is not a full replacement someone discounted. A spot repair under a slab, in a deep hole, or through a driveway leaves that row. Full replacement of about 50 to 80 feet is $4,000–$15,000. The two rows meet around $4,000–$4,500. That overlap is the moment to price both.

A camera inspection is typically $200–$600. It is how you know which row you are in. Some plumbers credit the fee if you hire the repair. A permit is often inside a full-replacement bid. When the bid leaves the city fee out, that fee is often $150–$600. Add that line once. Do not add it to a bid that already names the permit.

Landscaping restore along the trench — seed or sod, and shrubs or a short run of fence the dig took out — is often $500–$2,500. A designed relandscape of the whole yard can clear that. Driveway or sidewalk restore, a panel or a sidewalk bay the line actually crosses, is often $1,500–$6,000. A whole new driveway is the driveway paving guide and can clear the wider spread. Add the surface you have. A line that crosses lawn and a sidewalk can take both rows. A line that crosses neither takes neither.

A new cleanout, when the house does not already have one the crew can use, is typically $500–$1,500. A cleanout cut into a finished floor costs more than one in open soil. An existing cleanout that only needs the cap located is not this row.

What the range includes

The typical band assumes an existing single-family house, one main sewer lateral about 50 to 80 feet from the building to the connection near the property line, replaced in a yard a machine can reach, with ordinary backfill and rough grade. It includes the new pipe, the connection, haul-away of spoil the bid says it hauls, and a permit where the city requires one and the bid includes that fee. A shallow open-trench job in a lower-cost area sits toward the floor. Pipe bursting, lining, more depth, or a tight side yard sits toward the top.

Camera inspection, a missing cleanout, finished landscaping, and pavement are the add-on rows. They are not a second copy of the typical band. The new pipe on a dig or a burst is usually PVC or HDPE. A liner leaves the old pipe in the ground as the shell.

Whose pipe it is changes the bid before the method does. The lateral runs from the house toward the city main in the street. In many places the homeowner owns the pipe to the property line, or all the way to the tap, and the city owns the main. Some cities own the piece under the public right-of-way, and the homeowner owns the piece in the yard. The split is local. Ask the sewer department where their responsibility starts, and ask the camera crew for the distance from the cleanout to the failure, before you pay to replace a pipe on the city’s side. A backup that hits several houses on the block is a reason to call the city. A break under your yard is usually yours. This is a planning note, not a ruling on your parcel.

Homeowners insurance and a home warranty are contracts, and this page is not a reading of yours. A standard homeowners policy is built around sudden and accidental damage. Wear, roots, and settlement in a buried lateral are the kind of loss those policies commonly exclude, and the exterior service line is commonly a separate endorsement with its own cap and deductible. Water that damages floors inside the house is a different question from the cost of the pipe in the yard. A home warranty may name the sewer line and still exclude pre-existing conditions, a collapsed pipe, or any amount over a low dollar limit. Read the form before you treat either one as the budget. Neither one is inside the planning range.

The floor of the national spread, near $1,500, is one shallow spot repair in an open yard. The top, toward $30,000, is where a longer line, depth, a high trenchless rate, and a driveway or landscape restore usually land together. A lateral well past 100 feet, a full driveway, and a first-time connection off a septic system can clear that top. Treat a number above it as a different scope and ask which driver caused it.

None of the bands include a bathroom remodel, a kitchen remodel, a water heater, a tankless water heater, a whole-house repipe, a foundation repair, or a new driveway beyond the panel the trench actually crosses. A slow lavatory in a bath that is being gutted is a branch in that remodel. A backup at the floor drain, with the camera showing a failed lateral, is this guide. Do not fold the yard into the tile allowance, and do not fold a new tank into the sewer bid.

As a cross-check, not a bid: about 60 feet at $70–$200 is roughly $4,200–$12,000, inside the typical band. About 80 feet of open trench at $50–$150 is $4,000–$12,000. If a whole-line bid and that reading are far apart, the bid is a different method, a different length, or a restore the reading left out.

What moves the price

Driver	How it changes the bid
Method	Open trench is typically $50–$150 a foot in a yard the machine can reach. Pipe bursting is typically $70–$200. Lining is typically $80–$250. Trenchless saves the surface. It does not skip the pits, and lining cannot fix a pipe that has already collapsed.
Length	The 50-foot row is $4,000–$12,500. The 80-foot row is $4,000–$15,000. The 100-foot row is $7,500–$22,000. The permit and the connection do not fall in a straight line with the feet.
Depth and access	A shallow line in an open lawn is the planning job. A line the crew cannot slope safely, a side yard a machine cannot enter, or a run under a slab is labor, shoring, and often a different method.
What the line runs under	Lawn backfill is in the dig rate. Finished planting is often $500–$2,500. A driveway or sidewalk panel is often $1,500–$6,000. A whole driveway is its own project.
Pipe material	Clay and cast iron can often be lined or burst if the path is still open. Orangeburg that has blistered or gone oval usually has to be replaced, not lined. The new pipe is typically PVC or HDPE.
Cleanout and permit	A usable cleanout keeps the camera and some lining jobs simpler. Adding one is typically $500–$1,500. A bid with no permit, in a city that requires one, is not comparable. The city fee left out of a bid is often $150–$600.
Region	The same scope in a lower-cost area sits toward the floor of the row. A high-labor city sits toward the top and can leave it.

Clay, the rigid pipe in many older houses, is jointed every few feet. Roots enter at the joints, and a section can crack or slip out of line. A clay run that is round and open can often be lined or burst. A clay run with several offsets is a replacement. Cast iron, common in mid-century houses, corrodes from the inside, holds scale, and can belly as the wall thins. It is heavy to dig out. It can take a liner when the bore is still round enough for one. Orangeburg, a bituminized fiber pipe widely used from the 1940s into the 1970s, softens, blisters, and collapses. A liner needs a shell. Orangeburg often does not have one left. Plan on a dig or a burst when the camera shows it deformed. PVC is the usual new gravity pipe, with long joints that do not invite roots the way clay joints do. HDPE is the usual pipe a burst pulls in. Either one is the replacement. The camera of the pipe you already have still comes first.

Trenchless is the lower total when the dig would ruin a driveway, a sidewalk, a mature tree, or a finished floor, because those repairs are not in the per-foot rate. It is the higher total when the yard is open and the pipe is shallow, because the low dig rate would have put the soil back as the lawn. Lining is the least digging, and the wrong tool on a collapsed pipe. Ask for a dig price and a trenchless price on the same measured length so the surface you save is a number.

DIY or hire

Hire the replacement. The work is a utility locate, a permit in most cities, a trench that can cave in, or a trenchless tool that has to stay on the path, and a connection the city may have to see before it is buried. Call 811 before anyone digs. Gas and electric lines share the yard with the sewer more often than the grass suggests.

A careful owner can keep the cleanout cap accessible, notice a new wet strip in the yard, and snake a single slow lavatory that has a clog in the trap arm. That is maintenance. It is not a main-line replacement, and it is not a diagnosis. If every fixture backs up, stop snaking and get a camera. Digging a trench to the city main is not a weekend project.

Repair or replace

Have the line camera-inspected before you choose. The recording should show the material, the distance, and whether the failure is one spot or the run. A price for a full replacement with no recent video is a guess at which row you are in. Ask for the file. The inspection itself is the $200–$600 row, and a crew that will do the work often credits it.

Replace the line when the camera shows a collapse, offsets or root intrusions in more than one place, a belly that holds standing water along the run, or Orangeburg that is blistered or oval. Also replace when a spot-repair quote is a large fraction of a full replacement on 50 to 80 feet, the $4,000–$15,000 band. Do the work on your schedule. A backup that starts on a weekend is the same pipe plus an emergency fee and a cleanup inside the house.

Repair when the video shows one break, one offset, or one root mass and the rest of the pipe holds its shape and its pitch. That spot repair is the $1,500–$4,500 row when the hole is in an open yard. A second failure the next season, on the same old clay or cast iron, means the first patch bought a year.

The signs that usually lead to a camera are ordinary. More than one fixture backs up, especially the lowest one, a basement floor drain or a tub. A toilet gurgles when the washer drains. A sewage odor shows up in the yard or at that floor drain. A strip of lawn along the line is wet, sunken, or greener than the rest. Clogs return after a snake. The house is old enough for clay, cast iron, or Orangeburg, and the problem is the whole house rather than one sink. One slow lavatory, with the other fixtures fine, is a branch or a trap. It is not, by itself, a main-line replacement. If the camera shows a sound lateral and the backup is at the street, call the city. The main in the road is not this bid.

How to use this number

Ask for a written price that names the length, the method, the material of the new pipe or the liner, whether the permit and the camera are included, who restores the lawn and any pavement, and whether a cleanout is part of the work. Compare a 50- to 80-foot full replacement with $4,000–$15,000. Compare about 50 feet with $4,000–$12,500, about 80 feet with $4,000–$15,000, and about 100 feet with $7,500–$22,000. Compare the per-foot rate with $50–$150 for an open trench, $70–$200 for pipe bursting, and $80–$250 for lining. Keep a spot repair, a driveway, a bathroom remodel, a water heater, a tankless water heater, a whole-house repipe, and a foundation repair as their own lines.

A very low bid on a full replacement is a reason to ask whether the permit, the connection, and the backfill are included, not a reason to celebrate. A trenchless quote under an open-trench quote is a reason to ask which surfaces it avoids, and whether the host pipe can take a liner. A high bid should point at length, depth, method, pavement, or access. Two or three local bids on the same length and the same method are the number that matters. How this site sets the band is explained on the methodology page.
