Sewer Line Replacement Cost: 2026 Contractor Price Guide

The homeowner called it a clogged drain. She figured a couple hundred bucks, snake it, done. Then I ran the camera down the line and watched it stop dead at 32 feet, roots packed through a cracked clay joint like a fist. That is when a $225 drain cleaning turns into a five-figure conversation. And it happens more than most homeowners want to believe.

Sewer line replacement is one of those jobs where the price swing is huge and the homeowner has zero frame of reference. If you bid these, you need to know the ranges cold. Get your numbers dialed with our Sewer Line Replacement Cost Calculator, then use this guide to explain the bid so it sticks.

Quick Answer: What Does Sewer Line Replacement Cost?

Sewer line replacement costs $50 to $250 per linear foot installed, with most full-line jobs landing around $110 per foot. A typical residential replacement runs about $3,300 on the low end and climbs past $12,000 for long, deep, or trenchless runs under driveways. Open-cut is the cheapest method per foot. Trenchless costs more per foot but saves the yard.

What Drives the Price

No two sewer jobs price the same. Here is what moves the number, in rough order of impact:

• Length of the run. Priced per linear foot from the house cleanout to the city main or septic tank. A 30-foot run and a 90-foot run are different animals.
• Depth of the line. A line 3 feet down is a quick dig. A line 8 feet down needs shoring, a bigger machine, and a lot more labor.
• Method. Open trench, pipe bursting, or cured-in-place lining. This is often the single biggest swing.
• Pipe material. Old clay and Orangeburg fail and get replaced with PVC or ABS. Cast iron under a slab is its own headache.
• Access. Can a mini-ex reach the yard, or are you hand-digging past a fence and a gas line? Tight access kills production rates.
• Restoration. Ripping out a driveway, sidewalk, mature landscaping, or a finished basement floor adds thousands most homeowners never see coming.
• Permits and inspection. Nearly every municipality requires a permit and at least one inspection for a sewer lateral. Budget for it.

According to HomeGuide’s 2026 data, the blended national average lands near $150 per foot once you mix in trenchless jobs. Angi pegs the average project at roughly $3,300. Both numbers hide a wide spread, which is exactly why a real bid beats a rule of thumb.

Cost by Method

The method you pick sets the tone for the whole bid. Here is how the three main approaches compare.

Method	Typical Cost	Best For	Downside
Spot repair	$150 - $800 per repair	One isolated break or offset joint	Does nothing for a line that is failing everywhere
Open-cut replacement	$50 - $200 per linear foot	Accessible yards, shallow lines	Tears up everything above the pipe
Pipe bursting (trenchless)	$60 - $250 per linear foot	Runs under driveways and hardscape	Needs a host pipe intact enough to pull through
CIPP lining (trenchless)	$80 - $250 per linear foot	Cracked but structurally sound pipe	Not for fully collapsed lines

Open-cut wins on raw price per foot. Every time. But the moment a run crosses a driveway, a patio, or a 40-year-old maple, trenchless starts winning on total cost because you skip the demo and restoration. I have seen a “cheaper” open-cut bid balloon past the trenchless number once the concrete replacement got added back in.

Three Real Cost Examples

Numbers on a chart are one thing. Here is how they shake out on an actual bid.

Example 1: Spot Repair, One Cracked Joint

Camera found a single offset joint at 18 feet. Line is otherwise solid PVC. This is the cheap day.

Line Item	Cost
Camera locate and inspection	$250
Excavate and replace 8 ft section (8 lf x $70)	$560
Total	~$810

Spot repairs are the exception, not the rule. If the camera shows problems up and down the line, a patch just buys you a callback in eight months.

Example 2: Open-Cut Full Replacement, 45-Foot Run

Standard suburban front yard, clay pipe, line about 4 feet deep, grass to restore. The bread-and-butter job.

Line Item	Cost
Excavate and install 45 lf new PVC (45 lf x $95)	$4,275
Permit and city inspection	$300
Total	~$4,575

That is right in the range most homeowners can stomach once you explain it. Add real landscaping or a walkway over the line and it moves up fast.

Example 3: Trenchless Pipe Bursting Under a Driveway

Line runs 50 feet, straight under a poured concrete driveway. Open-cut here means demoing and repouring the drive, easily $4,000 to $6,000 on its own. Bursting skips all of that.

Line Item	Cost
Pipe bursting, 50 lf ($180/lf)	$9,000
Two access pits and camera verification	$500
Total	~$9,500

Higher sticker price, lower total damage. The driveway stays put. When I lay it out that way, most homeowners get it.

Regional Price Differences

Labor rates and permit costs swing hard by market. A plumber runs $50 to $150 an hour depending on where you are, and that flows straight into the per-foot number. These multipliers are ballpark adjustments off the national average, drawn from RSMeans city cost indexes and field experience.

Metro Area	Adjustment vs National Average
San Francisco, CA	+30%
New York, NY	+35%
Seattle, WA	+15%
Chicago, IL	+10%
Dallas, TX	-8%
Phoenix, AZ	-10%

Prices vary by region, and this is 2026 pricing. Always pull local permit fees and get your own material quotes before you hand a homeowner a number. Tell them to get multiple bids too. The honest ones will land close.

Where Contractors Lose Money on These Jobs

I have watched good plumbers eat their profit on sewer work for the same handful of reasons. Avoid these.

• Skipping the camera. Never bid a replacement off a guess. Run the camera, mark the depth, locate the line. A camera inspection costs you an hour and saves you a blown bid.
• Forgetting restoration. The pipe is half the job. The driveway, sod, sprinkler heads, and fence you cut through are the other half. Line every one of them out.
• Underbidding depth. Every extra foot of depth adds labor, shoring, and spoil to haul. A deep line is not a linear cost, it climbs.
• No contingency for surprises. Old homes hide things. I have opened trenches and found a second abandoned line, a gas service nobody marked, or bedrock. Build in 15 to 20 percent.
• Loose change-order language. Put the “if we find X, it costs Y” terms in writing before you dig. Verbal change orders on a torn-up yard are a fight waiting to happen.

Frequently Asked Questions

How much does it cost to replace a sewer line per foot? Most sewer line replacement runs $50 to $250 per linear foot installed. Open-cut is the low end at $50 to $200 per foot. Trenchless methods like pipe bursting and CIPP lining run $60 to $250 per foot because of the specialized equipment.

Is trenchless sewer replacement worth the higher cost? It depends on what is on top of the line. If the run crosses a driveway, patio, or mature landscaping, trenchless usually costs less overall once you add open-cut restoration back in. For an open grass yard, straight open-cut is almost always cheaper.

How long does a sewer line replacement take? A straightforward open-cut replacement is usually one to two days. Trenchless bursting can often be done in a single day. Deep lines, long runs, and heavy restoration push it to three days or more.

How do contractors estimate a sewer replacement bid? Start with a camera inspection to confirm the failure and mark the depth and length. Price the line per foot by method, then add permits, restoration, and a contingency. You can build the whole bid in our Sewer Line Replacement Cost Calculator and drop it straight into a proposal.

Should the customer pay for the camera inspection if they move forward? Most contractors roll the camera cost into the job if the homeowner signs, or credit it toward the replacement. A drain camera inspection runs $100 to $400 on its own. Set that expectation up front so there is no surprise on the invoice.

Turn the Estimate Into a Signed Job

Sewer work sells itself once the homeowner sees the camera footage. The part that loses jobs is the follow-up, the quote that takes three days to write and another two to send. By then they called someone else. This is where the plumbing estimate template and a system that moves fast earn their keep.

Contractors who switch to EstimationPro report cutting estimate time from a couple hours down to about 15 minutes per bid, which means the homeowner has your number the same afternoon you ran the camera. Try EstimationPro free. It builds the estimate, sends the proposal automatically, follows up with the homeowner so you win more of the bids you already send, and invoices when the trench is backfilled and the job is done.
