Gurgling toilets, a soggy yard patch that never dries, or a basement drain that fills when the washer runs can be signs that the sewer line may be damaged and not just clogged. For sewer line repair in Chesterfield, MO, the order matters. We find the problem first, then discuss the fix. Our 24/7 line handles active backups. While you wait, stop all water use, since every gallon goes to the lowest drain.
What a damaged sewer line looks like from inside the house
A sewer line fails in stages, and the early signs are easy to blame on something else. These are the patterns we hear most often.
Repeat backups after cleaning
The line is cleared and it clogs again within weeks. A cracked joint feeding roots or a sagging section holding water will do this.
Gurgling in several fixtures
Toilets, tubs and floor drains bubble when another fixture drains. Air is being pushed back through traps by a restriction.
Sewage smell in the yard or basement
A steady odor near the cleanout or along the line route can mean a leak, not just a vent problem.
Soft, green or sinking ground
A strip of lawn that stays wet or settles above the line suggests wastewater is escaping into the soil.
A cable that stops in the same place
Machines that halt at the same distance every time point to a collapse, an offset joint or a root ball.
How the break is found before anyone digs
Clear the line enough to see
A blocked pipe hides its own damage. We cable or jet it open first so the camera lens is not buried in sludge.
Run the camera
A waterproof camera on a flexible rod travels down the cleanout and records the wall, joints and flow. Cracks, roots, scale and standing water show clearly.
Locate and measure
A locator tuned to the camera head marks the spot on the surface and reads depth. This tells us whether the repair is in the yard, under a driveway or below the slab.
Review the footage with you
We stop the video on the problem and explain what we see. If the line is cracked, you hear that. If it is only dirty, you hear that too.
Price the options you actually have
Spot repair, lining and replacement each fit different damage. We give the price before work starts so you can compare.
Repair options by what the camera shows
No single repair suits every damaged line. This table shows how the findings usually map to a plan.
| What the camera shows | Typical repair | Trade-off |
|---|---|---|
| Short crack or one offset joint | Spot repair with a dug access hole | Digging at one spot, restoring yard or paving above it |
| Long stretch of cracks or root entry at several joints | Cured-in-place lining where the pipe qualifies | Pipe diameter shrinks slightly, and bad collapse rules it out |
| Collapsed or heavily bellied section | Dig and replace that section | More excavation, but fixes the slope |
| Corroded cast iron inside the house | Replace sections with new pipe and couplings | Walls or floor may need opening |
| Only grease or scale, wall intact | Jetting or cleaning, no repair | Repeat visits if the cause is habits |
Sewage smell or a collapsing yard?
A camera shows where the line is cracked, offset or choked with roots before anyone digs.
A crack with root intrusion: is a spot repair enough?
Many callers describe one localized crack in a plastic or clay line with roots pushing in, and ask for a spot repair. Sometimes that is exactly right. If the camera shows a single break and the rest of the pipe looks sound, a short section can be cut out and replaced.
Roots rarely go to a single opening, though. If the wall elsewhere is rough or has other hairline cracks, a spot repair stops one leak and leaves the next one to open in a year. We tell you what the footage shows both ways. The cheaper repair is not always the one that holds. If the cracks are long and the pipe is straight, a camera inspection of the full run helps decide between a spot fix and lining.
Trenchless lining and what it cannot do
Lining places a resin-soaked tube inside the old pipe and cures it into a new inner wall. It saves a trench across the yard or driveway, and it seals joints and small cracks. It is a good option for a straight run with intact structure.
It is not a cure for everything. A pipe with a deep belly, a collapse or a severe offset leaves a lined pipe that still holds water. The line also has to be cleaned first, often with hydro jetting, so the liner bonds to a clean surface. If the camera shows the pipe qualifies, lining is on the table. If it does not, we say so instead of selling it.
Cast iron pipe repair in older houses
Cast iron waste lines inside walls and under floors rust from the inside as scale builds up, and from the outside where condensation sits. The pipe narrows, then pinholes or cracks at a hub. A cast iron stack that gurgles, weeps along a seam or shows flaking rust is a candidate for repair.
A broken section can be cut out and replaced with new pipe joined by shielded couplings. A single failure does not always mean the whole line is gone, but several weeping joints usually do. The camera and a tap on the pipe tell us which story we are in.
Sewer backup in the house: what to do first
Sewage rising in a floor drain, a toilet that fills instead of flushing, or a tub that bubbles dark water is an emergency. The water is not clean, and the volume grows with every fixture that runs.
Call the 24/7 line. We handle same-day visits and after-hours backups, and the first goal is to open the line so the house drains again. Repair planning comes after the line is flowing and the camera has seen the damage.
- 1Stop all water use, including the washer, dishwasher and showers.
- 2Do not flush toilets, even if they seem to drain.
- 3Move belongings off the floor and open windows for ventilation.
- 4Photograph the water and affected items for your insurer.
- 5Keep children and pets out of the area until it is cleaned.
Main line cleaning, septic and lateral replacement: where this page stops
A blocked main line is not always a broken one. A machine or jet may be all that is needed, and the sewer line cleaning page covers that work. Replacing a lateral all the way to the street is a large project, and we assess it after a camera look shows the pipe cannot be saved.
Septic systems are outside this page. Tanks, drain fields and pump-outs need a septic contractor. First, confirm whether your property is on public sewer or a septic system. The answer varies by address, especially in large areas like Wildwood, so ask the building department or check your records before you call anyone.
What decides the cost of sewer line repair
A sewer repair can be small or large, and the camera decides which. We quote before work starts. These are the factors that move the number most.
Insurance note: homeowners policies commonly cover sudden accidental damage but not wear, age or roots. Sewer line coverage and water backup coverage are usually separate endorsements, so check your policy before authorizing repairs.

Chesterfield's lateral repair program, in plain terms
The City of Chesterfield says the property owner is responsible for the lateral sewer service line. Its Residential Sanitary Sewer Lateral Repair Program can cover certain lateral repairs up to $15,000, but only after a licensed plumbing company or licensed drainlayer has cabled the line and it did not clear.
Routine cabling is not reimbursable, and the owner pays the cabling and anything above the cap. A non-refundable $200 application goes in by mail or in person, with the cabling invoice, last year's tax receipt showing the sewer lateral fee and a notarized hold-harmless agreement. The City uses its own repair contractor for program repairs. Ask the City's Department of Public Works whether your repair qualifies, and keep your invoice.
Questions about sewer line repair in Chesterfield
Yes. The 24/7 line dispatches for active sewer backups. We open the line first and plan the repair after a camera shows the damage.
We clear the line and run a pipe camera. Roots, cracks, offsets and bellies show on video, while a line that is only coated needs cleaning and nothing else.
Sometimes. If the pipe is straight and mostly sound, lining can seal the cracks. Collapsed or badly bellied pipe usually needs a dug repair.
Yes. Damaged sections can be cut out and replaced with new pipe and couplings. If rust has spread through the whole line, we explain when replacement makes more sense.
We assess it after a camera look. Replacement is considered when the pipe is collapsed or too damaged for a spot repair or lining.
Policies often cover sudden accidental damage and exclude wear, age and tree roots. Backup and line coverage are usually add-ons, so read your policy.
Septic tanks and drain fields are outside what this page covers. Confirm whether your address is on public sewer or septic before calling a contractor.
