Replacing a 50-ft sewer line in St. Louis runs $4,650–$16,700, with $8,300 typical. Trenchless lining is $95–$260 a foot, pipe bursting $65–$260 a foot and a traditional dig $55–$260 a foot. Many problems never need a new line: a camera inspection is $140–$680, and a spot repair is $1,100–$5,750.
City of St. Louis owners of homes with six or fewer units pay a $28 fee with their property taxes, and the city's lateral program then fixes breaks under the public right of way with no further fee. It does not cover breaks under your own yard, or clearing clogs and roots anywhere on the line.
Sewer work in St. Louis should be done by a licensed plumber or sewer contractor with a permit ($30–$1,000) and an inspection. Ask the city or sewer utility who owns the pipe under the sidewalk and street: if it's theirs, that part of the bill may not be yours.

Figures cover the St. Louis metro area. Expect the top of each range where lines run under concrete or the street, and the bottom where they run under lawn.
Sewer line prices across St. Louis
Where the house sits changes the job. Dense blocks in Downtown, Grand Center & the Grove mean more concrete, street cuts and tight access; areas like St. Charles, Clayton & the suburbs usually have more yard to work in, which keeps digging cheaper.
Downtown, Grand Center & the Grove
- Per job
- $8,300–$14,550 per job
- Typical job
- $280–$1,500 / clog cleared + camera
The top of the city range. Short front yards and paved lots put more of the pipe under concrete, and street-cut rules and restoration fees land on your bill.
North St. Louis
- Per job
- $7,450–$12,850 per job
- Typical job
- $270–$1,400 / clog cleared + camera
A mix of older and newer homes. Older lines tend to have roots at the joints; newer PVC lines mostly just need clogs cleared. The camera tells you which you have.
South City & Dutchtown
- Per job
- $7,050–$12,050 per job
- Typical job
- $250–$1,300 / clog cleared + camera
Close to the city typical. Mid-century homes may still have their original clay, cast iron or fiber pipe, so a camera check before you buy is money well spent.
St. Charles, Clayton & the suburbs
- Per job
- $5,800–$10,400 per job
- Typical job
- $240–$1,250 / clog cleared + camera
Where homes have newer PVC lines, full replacements are rare; most calls are clogs, cleanout installs and backwater valves.
Real-world sewer line costs in St. Louis
Here's what common sewer line jobs cost in St. Louis in 2026, labor, pipe and basic yard restoration included.
Slow drains or a backup: snake the main and film it
The most common call. Snaking through a cleanout runs $140–$580, and a camera pass after it $140–$680. At night or on a weekend the call-out alone is $160–$420.
Roots in an old clay line: cut, jet and keep it clear
A root cutter ($160–$1,050) plus a hydro-jet ($330–$1,550) clears most root problems. If the camera shows the pipe is still in one piece, a yearly jet can hold off a $8,300 replacement for years.
One broken or sagging section: spot repair
Digging one hole and replacing a few feet of pipe costs $1,100–$5,750. A no-dig point liner over the same spot runs $1,300–$3,600, and fixing a belly where the pipe has sagged $1,650–$7,850.
Whole line, about 50 ft: trenchless
Lining 50 ft runs $4,750–$13,000 and bursting $3,250–$13,000, usually in a day or two with one or two small pits. Ask whether the price includes the camera before and after, the permit and the cleanout.
Line under the driveway or slab
Concrete is what makes this expensive: $8,200–$26,150 for about 50 ft with the concrete put back. Bursting or lining from two pits usually costs less than cutting a full trench through the driveway.
How much does sewer line replacement cost in St. Louis?
$4,650–$16,700 for a full 50-ft replacement, and $8,300 is what most St. Louis homeowners pay. The method sets the number: lining runs $4,750–$13,000 for 50 ft, bursting $3,250–$13,000, and a dig under lawn $2,750–$13,000. Under a driveway or slab the same job is $8,200–$26,150.
Smaller jobs cost far less: $140–$680 for a camera inspection, $1,100–$5,750 for a spot repair and $1,300–$3,600 for a no-dig point liner. Get the camera video before anyone quotes a full line. Re-checked against 56 sources, November 2026.
Sewer line prices in St. Louis (2026) by job
A full 50-ft replacement runs $4,650–$16,700, trenchless lining of the same line $4,750–$13,000, and a camera inspection $140–$680.
| Line on the quote | Low | Typical | High |
|---|---|---|---|
| Sewer camera inspection | $140 | $330 | $680 |
| Main line snaking | $140 | $330 | $580 |
| Hydro-jetting the main line | $330 | $710 | $1,550 |
| Spot repair (one section) | $1,100 | $2,750 | $5,750 |
| Trenchless lining, 50 ft | $4,750 | $8,500 | $13,000 |
| Pipe bursting, 50 ft | $3,250 | $8,000 | $13,000 |
| Dig and replace, 50 ft (before restoration) | $2,750 | $6,500 | $13,000 |
| Under a driveway or slab, 50 ft | $8,200 | $13,650 | $26,150 |
A $330 camera inspection is the cheapest line on this table and the one that decides the rest. It shows whether you need a $2,750 spot repair, a $2,350 point liner or a full $8,300 replacement.
What moves a sewer quote in St. Louis:
- What's on top of the pipe: lawn is cheap to dig; a driveway or slab job runs $8,200–$26,150.
- Depth: deeper lines need bigger holes, shoring and more hauling.
- Pipe condition: a round, cracked pipe can be lined ($95–$260 a foot); a collapsed one has to be burst or dug.
- Street and sidewalk: a cut in the public right of way adds $870–$6,250 plus city permits.
- Length: about $5,200 for 25 ft, $8,300 for 50 ft and $14,550 for 100 ft at typical St. Louis prices.
Ask every St. Louis contractor for the same four things: the camera footage, the method and length, the permit and restoration they include, and the warranty. Compare those, not the per-foot headline. Get a quote for your sewer job →
Sewer line cost in St. Louis by length
A 25-ft run is about $2,900–$10,450, a 50-ft line $4,650–$16,700, and a 100-ft run $8,150–$29,250 in St. Louis, before driveway or street restoration.
Worked example: a 50-ft line lined from one cleanout at $170 a foot is $8,500, plus a $330 camera check and a $250 permit, for about $9,080. The same line dug under lawn at $130 a foot is $6,500 before restoration.
Pits, permits, the camera and set-up cost about the same for any length, which is why short runs cost more per foot. A 100-ft line at typical St. Louis prices is about $14,550, not twice the 50-ft price.
St. Louis sewer repair methods compared
| Repair method | Cost | Best for |
|---|---|---|
| Trenchless pipe lining (CIPP) | $4,750–$13,000 for 50 ft | Cracked or root-filled pipe that is still round and on grade |
| Trenchless pipe bursting | $3,250–$13,000 for 50 ft | Broken, collapsed or undersized pipe; new pipe can go one size up |
| Traditional dig and replace (open trench) | $2,750–$13,000 for 50 ft | Shallow lines under lawn, sagging lines that need re-grading |
| Traditional dig, deep or under a driveway | $8,200–$26,150 for 50 ft | Lines under concrete when trenchless can't be used |
| Spot repair (dig up one section) | $1,100–$5,750 per repair | One break or bad joint in an otherwise sound line |
| Point repair liner (no dig, one section) | $1,300–$3,600 per repair | One crack or joint under a driveway, tree or walkway |
| Belly repair (dig and re-grade a low spot) | $1,650–$7,850 per repair | A sag that holds water and keeps clogging |
| Hydro-jet and root cut (no repair) | $490–$2,600 per visit | Roots or grease in a pipe that is still in one piece |
Per-foot price vs the full bill in St. Louis
A quote of $170 a foot for lining sounds simple, but 50 ft at that rate is $8,500 before the extras. Add the camera ($330) and the permit ($250) and the bill is about $9,080, before any access pit or cleanout. Compare whole-job prices, not per-foot rates.
Digging looks cheaper per foot ($55–$260), but restoration is extra: a sidewalk or street cut runs $870–$6,250, and a line under a driveway can reach $26,150. Trenchless costs more per foot and less to put back.
What's included in a St. Louis sewer line quote (and what costs extra)
A standard replacement quote covers the camera check, the digging or trenchless work, the new pipe, the connections at the house and the street side, and basic backfill and yard cleanup. It usually leaves out:
- The permit and inspection: $30–$1,000, set by the city
- Sidewalk or street restoration: $870–$6,250 when the line runs under public space
- Driveway or slab concrete: part of why a line under concrete runs $8,200–$26,150
- A new cleanout or backwater valve: $550–$2,100 and $540–$5,200
Ask for the warranty in writing, and a copy of the camera video from before and after the work.
Depth and frost
Depth depends on the slope from the house to the main and, in cold-winter cities, the frost line. Deeper trenches take longer and may need shoring. Deep lines push a 50-ft job toward $16,700.
What sits on top of the pipe
Lawn is the cheapest thing to dig through. A line under a driveway or slab runs $8,200–$26,150 in St. Louis because the concrete has to be cut out and poured again.
Pipe material and age
Clay joints let roots in, cast iron corrodes and scales inside, and Orangeburg fiber pipe, used through the 1970s, loses strength with age. Older pipe is more likely to need a full line than a spot fix.
Trenchless or dig
Lining runs $95–$260 a foot and bursting $65–$260, against $55–$260 for an open trench. Trenchless saves the yard, the driveway and the restoration bill.
Length of the run
Price scales with length: about $5,200 for a 25-ft run and $14,550 for 100 ft at typical St. Louis prices, because pits, permits and set-up cost the same either way.
Permits, street cuts and who owns the line
Permits run $30–$1,000. If the pipe crosses the sidewalk or street, a cut and restoration adds $870–$6,250, unless the city owns and fixes that part.
Local labor
St. Louis plumbers earn a median of about $37.02 an hour (BLS, May 2025), against $30.67 nationally. Sewer work is mostly labor and equipment time, so the typical St. Louis replacement is $8,300, above the $7,500 national typical.
- Get the camera video first.A $330 inspection shows where the problem is and how bad. Ask for the video file and the footage marks, and show them to a second contractor.
- Ask who owns the part under the street.Some cities fix the stretch under the sidewalk and street, or offer rebates and loans. One call to the sewer utility can take a big piece off the bill.
- Price a spot repair, not just a new line.If the camera shows one bad joint, a $1,100–$5,750 spot repair or a $1,300–$3,600 point liner may be all you need.
- Get trenchless and dig quotes side by side.Ask for both methods for the same length, with restoration included. Under concrete, trenchless usually wins; under open lawn, a dig can be cheaper.
- Don't wait for the emergency.An after-hours call-out adds $160–$420, and after-hours labor runs 1.5–3× the weekday rate. Book the camera and repair on a weekday when you can compare quotes.
- Keep roots back on a schedule.If roots are the only problem, a yearly hydro-jet ($710 typical) can buy years before a $8,300 replacement.
Get these in writing from any St. Louis contractor before you pay a deposit:
- The camera footage, with the distance to each problem marked
- The method (lining, bursting or dig) and the exact length of pipe
- Pipe material and size, and who handles the city connection
- Permit, inspection and any right-of-way or street-cut fees
- Restoration: lawn, sidewalk, driveway or street, and who does it
- Access pits, cleanouts or a backwater valve if they're part of the job
- Start date, days on site and what happens if they hit rock or water
- The written warranty and a camera check after the work

Do I need a permit to replace a sewer line in St. Louis?
Almost always. Expect $30–$1,000 for the permit and inspection, and more if the work crosses the sidewalk or street. A licensed contractor should pull it.
Does homeowners insurance cover sewer line replacement in St. Louis?
Usually not when the pipe fails from age, roots or wear. Separate sewer line warranty plans and policies exist, some offered through city partners; read the cap and exclusions before you count on one.
