Bellied pipe: what a fix costs
A bellied sewer pipe costs $1,500 to $5,000 to re-lay at the sag, $4,000 to $12,000 to line, or $5,000 to $15,000 to replace. Three worked examples.
Fixing a bellied pipe costs $1,500 to $5,000 for a spot re-lay, $4,000 to $12,000 to line the run, or $5,000 to $15,000 to replace it. Add a $200 to $500 camera inspection, and budget $300 to $800 for jetting before anyone measures.

Fixing a bellied pipe costs $1,500 to $5,000 for a spot re-lay of the sagging section, $4,000 to $12,000 to line the run, or $5,000 to $15,000 to replace it. None of those prices includes the $200 to $500 camera inspection that locates the belly, or the $300 to $800 jetting visit that clears it before anyone measures. Depth and surface finish decide where in each band your job lands.
What you are actually buying
A bellied pipe is a section of sewer line that has lost its fall and sagged into a low spot where water and solids collect. The repair is not a cleaning. It is a re-grading of that section, or a decision to abandon it in place and put a new pipe inside or alongside it.
Three products get sold for the same symptom, and they are not interchangeable:
| Scope | Typical cost | Footage covered | Restores fall |
|---|---|---|---|
| Spot re-lay | $1,500–$5,000 | The dip, usually 6–15 feet | Yes |
| Trenchless lining | $4,000–$12,000 | The whole run | No, smooths the bore only |
| Pipe bursting or replacement | $5,000–$15,000 | The whole run | Yes |
That third column is the one homeowners miss. Lining is priced across the run, so it looks expensive next to a spot fix that covers one dip. It also does not restore grade, so it is the wrong product when the sag is deep.
The line items that make up the bill
| Line item | Typical range | Notes |
|---|---|---|
| Camera inspection | $200–$500 | Footage and standing-water depth |
| Hydro jetting | $300–$800 | Clears solids so the pipe can be measured |
| Excavation | $600–$2,000 | Depth and shoring drive this line |
| Pipe and fittings | $150–$600 | Material and diameter |
| Bedding and compaction | $200–$600 | The part that stops the next belly |
| Surface restoration | $0–$3,000 | Lawn at the low end, concrete at the high end |
| Permit | $50–$500 | Varies by municipality |
| Post-repair camera pass | $0–$300 | Often bundled, sometimes not |
Restoration is the swing item. On a lawn, a patch of sod and some topsoil is a few hundred dollars. On a driveway, sawing, breaking, hauling, and repouring a 4-foot by 8-foot patch can pass $2,000 on its own.
Three worked examples
Example one: shallow belly under a lawn. Camera $350, jetting $400, re-lay of 10 feet at $2,200, sod and topsoil $250, permit $100. Total $3,300. The pipe work alone is $2,200 for 10 feet, or $220 per foot.
Example two: belly under a concrete driveway. Camera $350, jetting $450, re-lay of 12 feet at $3,400, concrete saw and repour $2,100, permit $150. Total $6,450. Same repair method, twice the bill, and $4,000 of it is depth and concrete.
Example three: four bellies on an 85-foot clay run. Two spot re-lays would be $3,800 each, or $7,600, plus two restorations at $900, for $9,400. A burst replacement of 85 feet at $13,000 plus one permit at $200 is $13,200. The spot route is cheaper by $3,800, but it leaves three unrepaired sections and two separate warranties.
The per-foot maths, and where it misleads
Per-foot pricing is the only common denominator between quotes, but it scales badly on short jobs because crew and equipment charges do not shrink with footage.
- $1,500 for 10 feet is $150 per foot.
- $5,000 for 10 feet is $500 per foot.
- $5,000 for 40 feet is $125 per foot.
- $15,000 for 85 feet is $176 per foot.
A $3,000 quote for 8 feet works out at $375 per foot, and a $3,000 quote for 30 feet works out at $100 per foot. Same money, different job. Always ask for the footage the contractor measured on camera, and check it against the report you were given.
Lining versus replacement, in dollars
Take a 60-foot run with a shallow belly and leaking joints throughout. Lining at $9,000 covers the whole run and smooths the joints, but the low spot remains, so water still stands an inch deep. Replacement at $11,000 eliminates the belly and the joints.
The gap is $2,000, or $33 per foot. If the belly is the only defect and the joints are tight, lining at $9,000 is the better buy. If the camera shows three low points, replacement at $11,000 does what lining cannot, and the $2,000 premium buys a line that drains by gravity as designed.
Add restoration to both. A lining job needs two small access pits, perhaps $600 of lawn. A replacement under a driveway needs a trench and a repour, perhaps $3,500. That flips the arithmetic: $9,600 for lining against $14,500 for replacement, and the $4,900 gap is not about pipe at all.
What the quote must itemize
A lump sum cannot be compared to another lump sum. Ask for these lines separately, in writing:
- Footage measured on camera, with the video file handed over
- Standing-water depth at each low point
- Excavation depth and whether shoring is included
- Bedding material and compaction method
- Surface restoration, by area and material
- Permit fees and who pulls the permit
- Post-repair camera inspection
- Warranty length, exclusions, and transferability
The bedding line is the one to read closely. A re-lay that goes back into the same uncompacted fill will sag again, and that is a warranty claim rather than a new problem. Ask what stops the replacement section from settling.
What to do next
- Book a camera inspection at $200 to $500 and ask for the footage mark and the water depth at the low point.
- Jet the line at $300 to $800 first if the camera is blocked, then re-inspect so the measurement is clean.
- Get three itemized quotes, at least one for a spot re-lay and one for lining, priced on the same footage.
- Compare total cost including restoration and permits, not the headline repair number.
- Ask each contractor what warranty covers a return of the sag, and get it in writing before signing.
The method-by-method trade-offs are set out in bellied pipe repair options, and the early signals are in bellied pipe warning signs. If the camera shows a fold rather than a dip, the price ladder changes and you should read collapsed pipe prevention. For the full range across methods, see sewer line repair cost.
Frequently asked questions
How much does it cost to fix a bellied sewer pipe?
A spot re-lay of the sagging section runs $1,500 to $5,000. Lining the run is $4,000 to $12,000, and full replacement is $5,000 to $15,000, both before a camera inspection at $200 to $500 and jetting at $300 to $800.
Is a belly repair covered by insurance?
Usually not. Insurers treat a sagging pipe as wear and deferred maintenance. Resulting damage such as sewage in a basement may be covered, and some policies sell a service line endorsement that includes the pipe itself.
Why does the same belly quote at $1,800 and $4,700?
Depth and surface. A belly two feet under a lawn is a short dig with grass to replace. The same belly six feet under a concrete driveway needs shoring, sawing, a concrete pour, and spoil hauling, which is where the extra $2,900 goes.
Is lining cheaper than re-laying a belly?
Per job, yes: $4,000 to $12,000 against a $1,500 to $5,000 spot fix sounds backwards, but lining covers the whole run while a re-lay covers one dip. On a single shallow belly the spot re-lay is cheaper; on a run with several, lining can win.
Can I just jet the line every year instead?
Sometimes. Jetting at $300 to $800 per visit is reasonable if the belly is shallow. Four visits at $500 is $2,000 over four years, which approaches the $1,500 low end of a spot re-lay, so the maths turns against waiting.
What is the cheapest honest fix for a belly?
A spot re-lay of the sagging length at $1,500 to $5,000, when the rest of the pipe is sound and the belly can be reached without removing a structure. Anything cheaper is a clearing, not a repair.
