Sewer Line Repair Cost Calculator
The Sewer Line Repair Cost Calculator estimates what it costs to dig up and replace a damaged section of sewer line. Choose what is wrong, how much line needs repair, how deep it is and what sits above it, and you get a planning budget split into materials, labor, surface removal, excavation and permit allowance, with budget, standard and premium ranges. You can add surface restoration to see the full cost of putting things back. It is free and takes under a minute. It is a planning estimate, not a bid.
Estimate your sewer line repair cost
Tell us what is wrong with the line, how long the damaged section is and how deep it runs. Then choose what is above it: a lawn, a driveway, the house itself or the street. Only your ZIP code and the type of damage are required. If you have not had a camera inspection yet, choose "Not sure".

HOW TO READ YOUR ESTIMATE
How to read your estimate
The large figure at the top is the estimated repair budget at standard pricing, shown as a range. For repairs longer than 10 feet it also shows an approximate cost per linear foot. Below it you will find three things:
Cost breakdown
Materials, labor, surface removal, excavation and service call, a permit allowance, and any restoration or hidden conditions allowance.
By work item
The dig-and-replace work, plus a cleanout, camera inspection and surface restoration if you added them.
Budget, Standard and Premium
Three repair levels that reflect different pipe, bedding and contractor experience.
Every figure is a planning range. The extent of the damage is confirmed by camera inspection and excavation and can change the cost. Actual contractor pricing may vary based on location, soil and site conditions, depth, material choice, labor market and project complexity.

MAIN GUIDE
How much does sewer line repair cost?
SPOT REPAIR, UP TO 10 FT
Standard planning budget. A budget repair starts near $1,350 and a premium one can reach about $4,500.
SECTION, 10–30 FT
Standard planning budget for a longer section.
LONG RUN, 30–60 FT
Standard planning budget for a long run.
A spot repair of up to 10 feet of sewer line typically budgets at about $2,300 to $2,750. A budget repair starts near $1,350 and a premium one can reach about $4,500. Longer repairs cost more: a 10 to 30 foot section budgets at about $4,550 to $5,450. These planning figures assume a cracked pipe at a typical depth of 4 to 8 feet under a lawn, repaired by digging, in normal working hours, with a permit allowance.
| Length repaired | Budget | Standard | Premium |
|---|---|---|---|
| Spot repair, up to 10 ft | $1,350 – $1,650 | $2,300 – $2,750 | $3,750 – $4,500 |
| Section, 10–30 ft | $2,700 – $3,250 | $4,550 – $5,450 | $7,400 – $8,850 |
| Long run, 30–60 ft | $5,200 – $6,200 | $8,600 – $10,300 | $13,600 – $16,200 |

How this calculator works
The calculator prices digging up the damaged section and replacing it with new pipe, keeping materials, labor and excavation apart. It adjusts labor and excavation for the type of damage, how deep the line is and what sits above it. Breaking out concrete or paving is priced as its own item. A permit allowance, surface restoration, a cleanout, a camera inspection and a hidden conditions allowance are added when you select them.
The three repair levels are built from different inputs for pipe, bedding and contractor experience. They are not one number multiplied up and down. Your ZIP code identifies your market for contractor matching and does not change the price.
Sewer line repair cost per foot
Per-foot cost falls as the repair gets longer. For a section of roughly 20 feet the calculator works out at about $230 to $270 per linear foot at standard pricing, and for a run of roughly 45 feet at about $190 to $230 per foot. A spot repair has the highest cost per foot, because the excavator, crew, permit and service call are the same whether 5 feet or 10 feet of pipe is replaced.
ROUGHLY 20 FT
Standard pricing, per linear foot.
ROUGHLY 45 FT
Standard pricing, per linear foot.
Why spot repairs cost more per foot
The excavator, crew, permit and service call are fixed, whether 5 feet or 10 feet of pipe is replaced.
What affects the cost of sewer line repair?
What is above the line
What sits on top of the pipe is often the biggest cost driver. A lawn is the easiest to dig through. Concrete and paving have to be cut and removed, a line under the house means cutting the floor slab and digging by hand, and a line under the street needs a city permit, traffic control and paving to city standards. The table shows a spot repair at standard pricing.
| Above the line | Repair only | With surface restoration |
|---|---|---|
| Lawn or bare soil | $2,300 – $2,750 | $2,450 – $2,950 |
| Landscaping | $2,350 – $2,850 | $2,800 – $3,350 |
| Walkway or patio | $2,600 – $3,100 | $3,250 – $3,900 |
| Driveway | $2,800 – $3,350 | $3,750 – $4,450 |
| Under the house | $3,600 – $4,300 | $4,350 – $5,250 |
| Street or sidewalk | $3,650 – $4,350 | $5,200 – $6,250 |
Depth
Deeper lines take more digging, and trenches over about 8 feet need shoring to keep the crew safe. For a spot repair, the standard estimate is about $2,100 to $2,500 for a shallow line, $2,300 to $2,750 at typical depth and $3,000 to $3,600 for a deep line.
Type of damage
A cracked pipe or a separated joint is a straightforward replacement. A sagging section has to be dug out and re-bedded at the correct slope, and a collapsed pipe is slower to excavate. For a spot repair, a sagging pipe budgets at about $2,600 to $3,100 and a collapsed pipe at about $2,500 to $3,000.
Length
Longer repairs use more pipe, labor and machine time, but the fixed costs are shared. When 30 feet or more needs repair, it is worth comparing the cost of replacing the whole line.
Emergency timing
Emergency repair raises labor by about 50 percent and doubles the service call, moving a standard spot repair to about $3,100 to $3,700. If the line can be opened temporarily with a snake, the permanent repair can often wait for normal hours.
Material, labor and excavation costs
Sewer repair is mostly labor and machine time. For a standard spot repair, the calculator budgets about $230 to $280 for pipe, couplings and bedding, $1,350 to $1,700 for labor, and $550 to $675 for excavation and the service call.
Permits, restoration and other costs
Permit allowance. About $140 to $170 at standard pricing, and about $340 to $420 where the work is in the street or sidewalk. Without a permit allowance, a standard spot repair budgets at about $2,150 to $2,600. Surface restoration. Not included unless you tick it. For a 10 to 30 foot section under a driveway, restoration brings the standard estimate to about $7,400 to $8,850. Camera inspection. Adds about $250 to $310. It confirms the damage beforehand and checks the finished repair. Cleanout. Adds about $350 to $440 when fitted while the trench is open, which is far less than installing one later. Hidden conditions. A contingency of about 8 percent of materials and labor at standard pricing, for rock, groundwater or extra damaged pipe.
Signs of a damaged sewer line
- Several drains back up or run slowly at the same time.
- Clogs keep returning after the line has been cleaned.
- Toilets gurgle when other fixtures drain.
- There is a sewage smell indoors or in the yard.
- A patch of lawn is soggy, sunken or unusually green.
These signs can also come from a simple blockage. A camera inspection is the way to tell the difference before paying for a repair.
Repair, replace or go trenchless?
| Option | Best when | Where to estimate it |
|---|---|---|
| Dig-and-replace repair | Damage is limited to one section, and the line is under a lawn or other soft ground | This calculator |
| Full line replacement | The pipe is failing in several places, or 30 ft or more needs work | Sewer Line Replacement Cost Calculator — Link still needed |
| Trenchless repair | The line is under a driveway, slab or street, or is deep, and the pipe has not collapsed or sagged | Trenchless Sewer Repair Cost Calculator — Link still needed |
Who pays for sewer line repair?
In most areas the homeowner is responsible for the sewer lateral from the house to its connection with the public main, including any part under the sidewalk or street. The city or utility is responsible for the main. Standard homeowners insurance often does not cover damage from wear or tree roots, though some insurers offer optional service line coverage. Check with your city and your insurer before work starts.
Regional pricing differences
Labor rates, soil conditions, frost depth and permit fees differ from one market to another. The calculator does not adjust for location. Treat the result as a national planning range, then get quotes from local sewer contractors to see where your market sits.
How to avoid unexpected costs
- Get a camera inspection of the whole line and keep a copy of the footage.
- Ask whether surface restoration is included, and to what standard.
- Ask how rock, groundwater or extra damaged pipe would be priced.
- Confirm who pulls the permit and who arranges utility locating.
- Ask for a trenchless price as well where the line is under concrete, paving or the house.
Questions to ask a sewer contractor
- Where exactly is the damage, and can you show me on the camera footage?
- How many feet will you replace, and with what pipe?
- Is this a fixed price, and what would change it?
- Does the price include the permit, inspection, backfill and restoration?
- What warranty do you give on the repair?
When to hire a professional
Sewer line repair involves deep excavation near buried utilities, work with raw sewage, correct pipe slope and bedding, and a permit and inspection. Trenches can collapse without proper shoring. This is work for a licensed sewer or plumbing contractor, and underground utilities must be located and marked before any digging.
QUICK ANSWERS
Quick answers
What is the average cost to repair a sewer line?
A spot repair of up to 10 feet of sewer line typically budgets at about $2,300 to $2,750 under a lawn, based on OmniEstimate’s standard planning assumptions. A 10 to 30 foot section budgets at about $4,550 to $5,450. Lines under driveways, slabs or streets, and deep lines, cost more.
What is a sewer lateral?
A sewer lateral is the pipe that carries wastewater from a house to the public sewer main. In most areas the homeowner owns and is responsible for the lateral, including the part that runs under the sidewalk or street, while the city or utility is responsible for the main.
What is a sewer line belly?
A sewer line belly is a section of pipe that has sagged, creating a low spot that holds water and waste. It causes repeated clogs. A belly is repaired by digging out the section and re-laying it on proper bedding at the correct slope; lining the pipe does not remove the sag.
Why is sewer repair under a driveway more expensive?
Sewer repair under a driveway costs more because the concrete or asphalt has to be cut and removed before digging, and replaced afterward. OmniEstimate budgets a standard spot repair at about $2,800 to $3,350 under a driveway, or about $3,750 to $4,450 with the driveway patched.
FREQUENTLY ASKED QUESTIONS
Frequently asked questions
How much does sewer line repair cost?
A spot repair of up to 10 feet under a lawn typically budgets at about $2,300 to $2,750 on standard assumptions. A 10 to 30 foot section budgets at about $4,550 to $5,450, and a 30 to 60 foot run at about $8,600 to $10,300. Depth, what is above the line and surface restoration can add considerably.
How much does sewer line repair cost per foot?
For a section of roughly 20 feet, the calculator works out at about $230 to $270 per linear foot at standard pricing, and for roughly 45 feet at about $190 to $230 per foot. Short repairs cost more per foot because the excavator, crew, permit and service call are fixed costs.
Who is responsible for sewer line repair, the homeowner or the city?
In most areas the homeowner is responsible for the sewer lateral from the house to its connection with the public main, even where it runs under the sidewalk or street. The city or utility is responsible for the main. Rules vary, so check with your city or sewer utility before work starts.
Does homeowners insurance cover sewer line repair?
Often not. Standard policies commonly exclude wear, corrosion and tree roots. Some insurers offer optional service line or sewer backup coverage. Check your own policy and insurer, as coverage varies.
How do I know if my sewer line is broken?
Several drains backing up or running slowly at the same time, repeated clogs, gurgling toilets, sewage smells indoors or in the yard, and a patch of lawn that is soggy, sunken or unusually green are all signs. A camera inspection confirms the damage and its location.
Is it cheaper to repair or replace a sewer line?
Repair is cheaper when the damage is limited to one short section. When 30 feet or more needs work, or the pipe is failing in several places, compare whole-line replacement, because the excavator, crew and permit are paid for once. A camera inspection of the full line tells you which applies.
Is trenchless sewer repair cheaper than digging?
It depends on what is above the line. Under a lawn, digging is usually cheaper. Under a driveway, slab or street, or for a deep line, trenchless is often cheaper overall because it avoids most excavation and restoration. Ask for both prices.
Does my ZIP code change the estimate?
No. Your ZIP code identifies your market and matches you with local professionals. It does not adjust the price. Local labor, soil and permit fees vary, so use the result as a planning range and compare local quotes.
