If sewage is backing up into your home, or you see a sunken wet patch in the yard with a sewage smell, stop using water and call (855) 575-2890. Our line is open 24/7. A damaged sewer line can leak wastewater into soil or push it back into the house, and neither situation improves with time.
Keep children and pets away from wet ground and any standing sewage. If sewage has entered living areas, avoid contact, ventilate if you can, and wait for the plumber before cleaning up.
Signs the sewer line is damaged, not just clogged
A clog is a blockage. Damage is a defect in the pipe itself. The two can look alike, which is why repeated cleaning without a camera look often turns out to be a waste of money.
Watch for backups that return after cleaning, a sewage smell in the yard or basement, slow drains throughout the house, soft or sunken ground along the line, and unusually green patches of lawn. Pests entering through cracks can also be a signal.
| Problem | What it looks like | Typical fix |
|---|---|---|
| Crack or hairline break | Seepage, damp soil, odor | Spot repair or lining |
| Offset or separated joint | Repeat clogs, roots | Joint repair or section replacement |
| Root intrusion | Slow drains, repeat backups | Cleaning plus repair of the entry point |
| Belly or sag | Waste settles, slow flow | Section replacement |
| Collapse | Total blockage, sunken ground | Excavation or trenchless replacement |
| Corroded cast iron | Rust, flaking, leaks | Replacement of failed sections |
When a damaged sewer line cannot wait until morning
A line that is leaking sewage or fully collapsed is an emergency. Our line is staffed around the clock for this reason, because raw sewage in the house or yard is a health and property risk.
Ground that suddenly dips or goes soft is worth a call at any hour. A leaking line can wash soil away over time, and the hollow that forms under the yard can keep growing. Do not drive or park over a sunken patch.
The first visit is usually about diagnosis and making the situation safe. On nights and weekends the goal is to make things safe and stop the backup where possible, then plan the repair for daytime hours.
How we find the problem
Repair starts with knowing exactly what is wrong. A plumber clears the line enough to run a camera through it, then watches for cracks, offsets, roots, bellies and collapses. A locator can mark the problem on the surface, so you know where digging would happen if it is needed.
That information lets us explain whether a spot repair, a section replacement or a full line replacement fits. It also tells you whether trenchless methods are possible. Our sewer inspection page covers what the camera shows.
Cast iron sewer pipe
Cast iron was a common choice for drain and sewer pipe in older homes. Over decades it can rust from the inside, flake, and eventually crack or leak. Corroded cast iron often shows up as repeat clogs because the rough inner walls catch debris.
Helena's growth has been mostly since 1990, so older pipe materials are more likely to turn up in Old Town than in newer subdivisions. If you own an older home, a camera look shows the inside condition. A failed section of cast iron is usually cut out and replaced with modern pipe, and the rest can be assessed on its own.
Trenchless sewer repair options
Trenchless methods repair pipe with little or no digging. They can save lawns, driveways and landscaping, which matters when the line runs under a finished yard.
- Pipe lining: a resin-saturated liner is pulled into the old pipe and cured to form a new pipe inside the old one
- Pipe bursting: a new pipe is pulled through as the old one is broken apart underground
- Spot lining: a short liner patches one damaged section
Not every line suits trenchless work. A collapsed pipe, severe offsets or a badly sagging section may need excavation. The camera look decides which options are open to you.
Open-trench repair and replacement
Traditional excavation is the right choice when the pipe has collapsed, when a section sags, or when the line must change slope. It exposes the pipe for a direct fix and allows the plumber to correct the grade so waste flows properly.
Digging means planning around landscaping, driveways, and utilities. Before any digging, the site should have underground utilities marked. Check with the Helena building department about permit requirements for your project.
What a sewer repair project looks like
- Emergency visit to stabilize the situation and clear any backup
- Camera inspection to find the exact defect
- Locate and mark the damaged section
- You receive a clear price before work starts
- Repair or replacement of the damaged section
- Camera check afterward to confirm the line is sound
Helena homes and sewer lines
Helena grew from 3,918 people in 1990 to 20,914 in 2020 and 91.1 percent of homes are owner-occupied, so most sewer lines here are the homeowner's to maintain. That growth also means many sewer laterals are newer, though newer does not mean damage-proof. Settling soil, roots and construction disturbance can affect any age of line.
Buck Creek and the Cahaba River run through the city, so some properties sit near low or wet ground. A line in saturated soil is harder to inspect and repair, and wet conditions are worth mentioning when you call. For sewer service questions, contact the City of Helena Utilities Board at (205) 663-1670 or check with them on which part of the line they maintain.
Neighbors in Pelham and Calera can use the same emergency number. When the line only needs a good cleaning, our sewer line cleaning page explains that process, and hydro jetting covers the heavier option.
Repair or replace?
Repair makes sense when damage is limited to one section and the rest of the line is sound. Replacement fits better when the pipe is failing in several places or is a material known for fatigue. The decision comes from the camera findings, not from a guess.
Ask for the reasoning behind a recommendation. You should understand why the plumber suggests lining over replacement, or digging over trenchless work. If a project is large, a second opinion is a fair request.
Before the plumber arrives
- Stop using water, including washers and dishwashers
- Keep people and pets away from wet ground and standing sewage
- Do not drive or park over a sunken or soft area of the yard
- Find any paperwork about the home's sewer line, if you have it
- Note where you see smells, wet spots or slow fixtures
- Clear access to the cleanout, if you know where it is
- Take photos of damage for your insurance claim
What affects the cost of sewer line repair
- Type of repairSpot repair, lining, bursting and full replacement are priced differently
- Length of damaged pipeA short section costs less in time and materials than a long run
- Depth and accessDeep lines and tight areas need more work
- Surface restorationDriveways, landscaping and patios affect the scope
- Pipe materialCast iron, clay and plastic each call for different handling
- After-hours timingEmergency visits at night or on weekends can carry different rates
You get a clear price before work starts. Sewer line damage is sometimes covered by home warranty or insurance plans. Ask your provider before repair work begins.
Want your real number? Call (855) 575-2890Helena sewer line repair questions
Yes. The emergency line runs 24/7, including weekends and holidays. Call (855) 575-2890 and we will stabilize the problem first, then plan the repair.
Repeat backups after cleaning, sewage smells, soft or sunken ground and wet patches point to damage. A camera inspection confirms it.
Not always. Lining and pipe bursting can repair some lines without trenching. Collapsed or sagging lines often need excavation. The camera inspection decides.
It can be in older homes. Cast iron rusts and flakes over decades. If the camera shows failing sections, those parts are replaced.
Generally the homeowner owns the lateral on their property. Check with the City of Helena Utilities Board at (205) 663-1670 to confirm where the city's part ends.
Wet weather slows some work, and open trenches are harder in saturated soil. We can still diagnose and make a line safe. Ask us about scheduling.
