Quick Answer
Most sewer line replacements cost $3,000 to $30,000 in 2026, and a typical residential lateral runs about $110 per linear foot installed. Open trench work is $50-$150 per foot, trenchless pipe bursting is $60-$200 per foot, and CIPP lining is $80-$250 per foot. A single failed section repaired in place runs $125-$400 per foot, usually $1,000-$3,200 all in. Depth adds about 25% at 6 to 10 feet and 50% past 10 feet, but only on excavated methods. The trench is the cheap part. Putting the driveway and the lawn back is what blows the budget, so measure that square footage before you quote. Prices vary by region and by how deep your city buries the main, so get multiple bids before you commit.
Inputs you'll need
- The replacement method (open trench, pipe bursting, CIPP lining, or spot repair)
- The line length in linear feet, from the house to the main
- The trench depth (excavated methods only)
- Square feet of concrete, asphalt, and lawn you have to restore
- Whether the job needs a camera scope, a permit, and a new cleanout
Sewer line replacement cost by method
| Method | Cost (Installed) | Best For |
|---|---|---|
| Open trench (traditional dig) | $50-$150 / linear ft | Shallow runs under lawn, or a fully collapsed pipe |
| Trenchless pipe bursting | $60-$200 / linear ft | Lines under driveways, patios, sidewalks, or mature trees |
| Trenchless CIPP lining | $80-$250 / linear ft | Intact pipe leaking at the joints, usually clay tile |
| Spot repair (one section) | $125-$400 / linear ft | A single failure when the rest of the run scopes clean |
| Camera scope | $100-$800 flat | Every job, before you quote a number |
| Permit and inspection | $200-$1,000 flat | Nearly all jurisdictions, and they want the trench open |
| New cleanout | $600-$2,000 each | Often required at the property line on a replacement |
| Concrete or asphalt restoration | $6-$15 / sq ft | Any trench crossing a driveway, walkway, or patio |
| Lawn and landscape restoration | $0.80-$2.60 / sq ft | Sod or seed over the trench line |
Per-foot costs are installed and anchored to 2026 published ranges. Depth multipliers apply to excavated methods only: x1.25 at 6 to 10 feet, x1.50 past 10 feet. Prices vary by region, so always get multiple bids before you commit.

Sewer Line Replacement Cost Guide
Per-foot pricing by method, why trenchless can be cheaper than digging, and the restoration line item most bids forget.
How Much Does Sewer Line Replacement Cost in 2026?
Most sewer line replacements run $3,000 to $30,000 in 2026, with a typical residential lateral landing around $110 per linear foot installed. The number moves on three things: the length of the run, whether you dig a trench or go trenchless, and how much concrete and lawn you have to put back afterward.
- Open trench (traditional dig): $50-$150 per linear foot
- Trenchless pipe bursting: $60-$200 per linear foot
- Trenchless CIPP lining: $80-$250 per linear foot
- Spot repair (one bad section): $125-$400 per linear foot, usually $1,000-$3,200 total
- Camera scope: $100-$800 flat
- Permit and inspection: $200-$1,000 flat
A standard 50-foot lateral at 6 to 10 feet deep, dug open with a camera scope, a permit, and 200 square feet of lawn put back, prices out around $4,100 to $13,400 with a 15% contingency. Prices vary by region and by how deep your city buries the main, so get multiple bids before you commit.
Key Takeaways
- Sewer line replacement: $3,000-$30,000, typically $110 per linear foot
- Trenchless costs more per foot but often less overall once restoration is counted
- Length, depth, and surface restoration drive the number, not the house size
Trenchless vs Open Trench: Which Is Actually Cheaper?
Open trench is cheaper per foot. Trenchless is often cheaper per job. That sounds like a contradiction until you price the restoration. Digging a 50-foot trench across a driveway means you are also buying back that driveway at $6 to $15 per square foot. Pipe bursting needs two access pits and leaves the concrete alone.
- Open trench wins when the run is shallow, crosses nothing but lawn, and the pipe is collapsed
- Pipe bursting wins when the line runs under a driveway, a patio, a sidewalk, or a mature tree
- CIPP lining wins when the host pipe is intact but leaking at the joints, and it needs an intact pipe to cure against
- Depth kills open trench: a 6 to 10 foot trench adds about 25%, and over 10 feet adds about 50% for shoring, spoil, and a bigger machine
The mistake contractors make is quoting trenchless against open trench on the per-foot number alone. Put the concrete and the sod back into both columns and the ranking flips more often than not.
Key Takeaways
- Open trench: cheapest per foot, most expensive to restore
- Depth adds 25% at 6-10 ft and 50% past 10 ft, and only to excavated methods
- CIPP lining requires a structurally intact host pipe, not a collapsed one
Scope the Line Before You Quote a Number
A camera scope costs $100 to $800 and it is the cheapest insurance on the whole job. Nobody prices a sewer lateral honestly from the driveway. What the homeowner describes as "a slow drain" turns into root intrusion at three joints, a bellied section holding water, and 12 feet of Orangeburg that has gone soft.
- Orangeburg pipe: tar paper pipe used through the 1970s, it deforms and collapses, and it is never a spot repair
- Clay tile: roots find every joint, which is where lining earns its keep
- Cast iron: scales and narrows from the inside, so the scope reads smaller than the pipe actually is
- Bellies: a sag holds water and solids, and lining a belly just gives you a smoother belly
Carry a 15% contingency on any sewer job. This is the classic case of hidden work getting you: you cannot see what you are dealing with until the machine opens the ground, and by then the homeowner's yard is already torn up and you have no leverage to renegotiate.
Key Takeaways
- Camera scope first: $100-$800 beats a $10,000 change order
- Orangeburg and bellied lines cannot be spot repaired or lined
- Carry a 15% contingency on every sewer bid
What Homeowners Forget to Budget For
The trench is the cheap part. Homeowners fixate on the per-foot pipe number and forget that a sewer job takes a bite out of everything sitting on top of the line. Getting these into the estimate up front is the difference between a clean job and an argument in the driveway on day four.
- Concrete or asphalt restoration: $6-$15 per square foot to replace driveway, walkway, or patio
- Lawn and landscape: $0.80-$2.60 per square foot for sod, and mature plantings are a separate conversation
- New cleanout: $600-$2,000, and many jurisdictions now require one at the property line
- Permit and inspection: $200-$1,000, and the city will want to see the trench open
- Street or right-of-way work: if the failure is past the property line, the tap and the traffic control can double the job
Price the restoration square footage before you hand over a number. Measure the driveway, measure the lawn, and put both on the estimate as their own line items so the homeowner sees exactly what they are paying for.
Key Takeaways
- Restoration is a real line item: $6-$15/sq ft hardscape, $0.80-$2.60/sq ft lawn
- Many cities now require a cleanout at the property line ($600-$2,000)
- Work past the property line means permits, taps, and traffic control
How to Use This Calculator
Pick the replacement method
Choose open trench, trenchless pipe bursting, trenchless CIPP lining, or a spot repair. Each one is priced per linear foot, and each one fits a different pipe condition.
Enter the line length and trench depth
Measure the run from the house to the main, or just the failed section for a spot repair. Set the depth for excavated methods. Trenchless work ignores depth because there is no trench.
Add the scope, permit, and cleanout
Keep the camera scope on ($100-$800). Add the permit ($200-$1,000) and a new cleanout ($600-$2,000) if your jurisdiction requires one at the property line.
Measure the restoration square footage
Enter the concrete or asphalt you have to put back ($6-$15 per sq ft) and the lawn you have to reseed or sod ($0.80-$2.60 per sq ft). This is the line item most bids miss.
Set a contingency and review the total
Carry 15% on any sewer job. You cannot see what is in the ground until the machine opens it. The calculator returns a low-to-high total and an all-in cost per foot you can bid from.
Sewer Line Replacement Cost Formulas
Pipe & Labor = Linear Feet x Cost per Foot x Depth Multiplier
Add-Ons = Camera Scope + Permit + Cleanout
Restoration = (Hardscape sq ft x $6 to $15) + (Landscape sq ft x $0.80 to $2.60)
Subtotal = Pipe & Labor + Add-Ons + Restoration
Total = Subtotal x (1 + Contingency %)Where:
- Cost per Foot
- = $50/lf open trench to $250/lf CIPP lining, by method
- Depth Multiplier
- = x1.00 under 6 ft, x1.25 at 6-10 ft, x1.50 over 10 ft. Excavated methods only.
- Add-Ons
- = Camera scope $100-$800, permit $200-$1,000, cleanout $600-$2,000
- Restoration
- = Concrete or asphalt $6-$15/sq ft, lawn $0.80-$2.60/sq ft
- Contingency
- = 15% recommended on any sewer job, because the ground hides the scope
