Typical cost for this job$3,230 - $11,000From published national cost guides, checked on the date above the calculator. Sources are listed below it.
1. What's going on
Main problem
Have you already had a camera inspection?
2. Describe the job
Trenchless. Coats the inside of the existing pipe.
HomeGuide says most full sewer line replacements are around 40 ft.
Clay is an older material that lasts 30 to 60 years, according to HomeGuide, which also notes that nearby tree roots affect how long any sewer line lasts. If roots keep coming back, a camera inspection shows whether the damage is one spot or spread along the line, which decides between a spot repair and a full reline or replacement.

How we got this
- HomeGuide puts pipe lining (CIPP) at $90 to $250 per linear ft and Angi at $80 to $250, so this calculator uses the wider $80 to $250. Length of line times that rate: 40 ft × $80 to $250 per ft = $3,200 to $10,000 (HomeGuide, Angi)
- Trenchless methods dig only small entry and exit pits, not a trench along the line, so this calculator adds no restoration line for what is on top of it.
- This calculator does not add a depth line for trenchless work.
- Extras from the boxes you checked (the cleanout box is not checked, so none is added; the permit range spans both HomeGuide's $30 to $500 and This Old House's $100 to $1,000): permit: $30 to $1,000 (HomeGuide, This Old House)
- Total: $3,200 to $10,000 + $30 to $1,000 = $3,230 to $11,000
The idea behind it: The pipe work is priced by the linear foot for a full-line method, or per job for jetting and spot repairs, and a cleanout and a permit are added as their own lines. Digging along the pipe can add lines for landscaping, driveway or slab work above it and for a deeper dig, which trenchless methods skip because they dig only small pits.
A camera inspection ($100-$500) confirms the exact length and location of the damage before anyone digs or lines anything, so the price you're quoted matches the actual problem instead of a guess.

4. Compare methods side by side
Same length, depth and surface as above, priced under each full-line method. Spot repair and hydro jetting aren't full-line replacements, so they're left out of this comparison.
| Method | Typical total |
|---|---|
| Open trench (dig and replace) | $2,430 - $10,200 |
| Trenchless pipe bursting | $2,430 - $9,000 |
| Trenchless pipe lining (CIPP) (selected) | $3,230 - $11,000 |
Trenchless methods (bursting, lining) usually cost more per foot but need little to no restoration. Open trench usually has the lowest per-foot labor rate but adds the landscaping, driveway or concrete repair cost shown in the line items above.
Enter the problem, the method being used and the length of line involved to see the typical cost, compare it against the other repair methods side by side, and check whether a quote you already have is fair.
This calculator is for a home connected to a municipal or shared sewer system. If your home uses a septic tank and drain field instead, none of the numbers above apply: septic problems are usually a tank pumping, tank repair or drain field issue, and the cost drivers are different from what's priced here.
How this is calculated
The estimate starts with a per-linear-foot rate for the method you select, taken from published national cost guides. Hydro jetting is priced per job. Spot repair is priced per job, with the top end rising for a longer damaged section. Open trench and spot repair add a restoration line for whatever sits on top of the pipe, based on the dug length and a trench width you can edit, plus extra for depth or difficult access. Trenchless methods (pipe bursting and CIPP lining) skip most of that restoration cost because they only need small entry and exit pits, not a trench the full length of the line. A cleanout and a permit are added on top when you check those boxes.
Worked example
A homeowner has recurring backups traced to root intrusion in a 40-foot clay sewer line, 4-8 feet deep, running under open lawn. Their plumber has already run a camera inspection and recommends CIPP pipe lining with a new cleanout added, and the city requires a permit.
| Line item | Typical range |
|---|---|
| Trenchless pipe lining (CIPP), 40 ft | $3,200 - $10,000 |
| Add a sewer cleanout | $500 - $2,000 |
| Permit | $30 - $1,000 |
| Total | $3,730 - $13,000 |
Because they already have a camera inspection and a trenchless method is selected, the calculator does not raise a second-opinion flag. If this same homeowner had instead been quoted a full open-trench replacement of the same 40 feet under that lawn, without ever having a camera inspection, the tool would flag it: a camera inspection often shows root damage is limited to a shorter section, where lining or a spot repair costs less than digging up the whole line.
What this estimate leaves out
- Your line: only a camera inspection shows its material, depth, condition and the real length to be fixed.
- Septic systems: the numbers apply to a home on a municipal or shared sewer, not to a septic tank or drain field.
- Local prices: every figure is a national range from the cited guides, and city permits, utility locates and labor rates change the real total.
- Repairs beyond the line itself, such as a collapsed driveway, a damaged landscape or work inside the house, unless an option above adds them.
For a final price, get a written quote after a camera inspection, and a second opinion before a full replacement.
Reading a sewer line quote
The single biggest thing that changes a sewer quote isn't the pipe, it's what's on top of it and how deep it runs. Two contractors bidding the identical 40-foot open-trench job can land up to about $3,000 apart just from driveway removal and repair versus plain lawn (a 3-foot-wide trench is 120 sq ft, at $1 to $25 per sq ft for concrete: Angi and HomeAdvisor price driveway repair at $1-$25/sq ft, This Old House at $1-$20/sq ft, and HomeGuide prices removal alone at $3-$8/sq ft). Before comparing dollar totals between quotes, make sure both contractors are pricing the same method, the same length, and the same restoration scope. A quote that's unusually low for an open trench job under a driveway is worth a second look at what "restoration" actually includes.
A quote for a full replacement that was written without a camera inspection is the other thing worth questioning. Inspections cost $100-$500 (This Old House; HomeGuide says $125-$500) and often change the recommended method entirely; a contractor who skips straight to "replace the whole line" without one may be overselling the scope of the job.
Before you sign a sewer quote
- Get a camera inspection first if you're being quoted a full replacement, and ask to see the footage before you sign anything.
- Confirm the contractor is licensed, bonded and insured.
- Get the restoration scope, landscaping, driveway or concrete, in writing, not just a verbal promise.
- Make sure the quote states the method, the length of line involved, and the depth, so you can compare it to another bid on the same terms.
- If a quote comes in below the typical range, confirm it includes permit fees and full restoration, and that the dig goes all the way to the city main.
- If a quote comes in above the typical range, ask what's driving it: unexpected depth or obstacles, a second cleanout, extensive restoration, work under a slab, or an emergency rate. If none of those apply, get one more quote.
Open trench vs. trenchless: what actually changes the price
Open trench runs $50-$200 per linear foot, according to This Old House, and is usually the cheaper method on a per-foot basis, but it requires digging a trench the full length of the pipe, which means restoring whatever was on top of it afterward. Trenchless pipe bursting ($60-$200/ft per HomeGuide) and CIPP lining ($80-$250/ft per Angi; HomeGuide says $90-$250/ft) cost more per foot but need only two small access pits, so there's little to no landscaping, driveway, or concrete restoration cost on top. Under open lawn with nothing to restore, open trench usually wins on total price. Under a driveway, patio, or established landscaping, trenchless often wins once restoration is priced in, even though the per-foot number looks higher. The method comparison table in the calculator runs both sides of that math for your specific length, depth and surface.
Questions people ask
How much does it cost to replace a sewer line?
A full sewer line replacement typically costs $50 to $250 per linear foot, or about $2,000 to $10,000 for a typical 40-foot residential line, according to HomeGuide. This Old House puts the national average at $3,320, with most homeowners paying $1,390 to $5,320. The wide range comes from the method used (open trench vs. trenchless), the depth of the line, what sits on top of it (lawn vs. driveway vs. under the house), and the pipe material.
What does sewer line repair cost compared to full replacement?
It depends heavily on the method and how much of the line is damaged. HomeGuide prices trenchless pipe bursting at $60-$200 per linear foot; for CIPP pipe lining, HomeGuide says $90-$250 per linear foot and Angi says $80-$250 per linear foot, so this tool uses the combined $80-$250 range. Angi puts a spot repair of a cracked section at $600-$1,050, and HomeAdvisor prices partial replacements at $50-$250 per foot, so a longer damaged section can cost more. HomeGuide's overall repair range of $150 to $3,800 covers every method, and its $150 low end is for snaking, not digging. HomeGuide gives two figures for clearing a line: basic snaking runs $150-$500, and hydro jetting for roots or heavy buildup runs $250-$1,400 across its two estimates. None of the jetting or snaking methods fix a cracked, collapsed, or sagging pipe; they only clear what's inside it.
Is trenchless sewer repair worth the higher per-foot cost?
Often, yes, once you account for restoration. This Old House puts trenchless methods (bursting and lining) at $60-$250 per linear foot, versus $50-$200 for open trench, but they need only small entry and exit pits instead of a trench the full length of the line. If your line runs under a driveway, patio, or mature landscaping, the restoration cost for an open trench (landscaping $4-$12/sq ft per HomeGuide and This Old House, concrete $1-$25/sq ft per Angi and HomeAdvisor; This Old House says $1-$20) can easily erase the per-foot savings. If your line runs under open lawn with nothing to restore, open trench is usually the cheaper choice overall.
Should I get a camera inspection before I approve a sewer quote?
Yes, especially before approving a full open-trench replacement. A camera inspection costs $100-$500 (HomeGuide says $125-$500, This Old House says $100-$500) and shows exactly where the damage is and how bad it is. Contractors sometimes quote a full replacement without one; a camera inspection often reveals the damage is a short section, which a much cheaper spot repair or lining job can fix. Ask to see the footage before you sign anything for a full-line replacement.
What pipe material is my sewer line likely made of, and does it matter?
It depends on the age of the home. HomeAdvisor notes that newer homes use PVC and ABS, while older homes may have copper, Orangeburg, clay, cast iron or lead. HomeGuide puts Orangeburg (tar-paper) and clay pipe at 30 to 60 years, and This Old House describes Orangeburg as prone to deterioration over time. HomeGuide adds that nearby tree roots, soil conditions and maintenance all affect how long a line lasts. This Old House says cast iron lasts 75-100 years with proper care and PVC lasts 100 or more years; HomeGuide puts PVC, cast iron and copper at 50 to 100 years. A camera inspection will identify your pipe's material if you don't already know it.
Does homeowners insurance cover sewer line repair or replacement?
Usually not for normal wear and tear, root intrusion, or age-related failure, which is how most sewer line problems happen. Standard homeowners policies more often cover sudden accidental damage, like a line crushed by a falling tree, and some insurers offer a separate sewer line endorsement or service line coverage for an added premium. Check your specific policy; this isn't legal or insurance advice.
How long does a sewer line replacement take?
It depends on the method. This Old House's sewer line repair guide says trenchless methods (pipe bursting or CIPP lining) are often finished in about a day, while a full open-trench replacement usually takes 3 to 5 days because of the digging and restoration involved. Across all job types the overall range is 1 to 5 days. Ask your contractor for a day-by-day estimate before you sign, especially if you only have one bathroom and need to know how long it will be out of service.
