When a line needs full replacement
A single crack or root-damaged section can often be spot-repaired or lined. Full replacement is the right call when the pipe is past saving:
- The line has collapsed or crushed
- Repeated backups even after cleaning
- It's Orangeburg (tar-fiber) pipe
- A bellied / sagging section holds waste
- Severe root destruction at many joints
- Widespread corrosion or age (old clay/cast iron)
We confirm with a camera inspection before recommending replacement — no guesswork.

How we replace a sewer line
We match the method to the line's condition and grade — least-invasive option that lasts.
Trenchless pipe bursting
A bursting head fractures the old pipe outward and pulls a new seamless HDPE line in behind it — through two small pits, no trench across the yard. ~50-year pipe.
Trenchless pull-in-place
For suitable lines, a new pipe is pulled through the existing path with minimal excavation — preserving driveways and landscaping.
Open-trench replacement
Required for bellied lines, total collapse, or grade correction — a precise excavation to install new PVC/HDPE at the right slope, then full restoration.
Why a bellied line can't go trenchless
Trenchless bursting follows the existing path — so it leaves a sagging "belly" exactly where it is. A bellied line holds waste and keeps clogging until the low spot is dug up and re-graded. We'll tell you honestly when a dig is the only real fix.
Sewer line replacement cost in Portland

| City permit + inspection fee | ~$325 + ~$295 |
Estimates as of 2026 for guidance only; price depends on length, depth, pipe material, method, and surface restoration (landscaping, driveway, sidewalk). You always get an exact, on-site quote after a camera inspection — and financing is available.
Permits, the right-of-way & who owns the lateral
In Portland, the property owner owns the sewer lateral from the house out to the city main — including the portion in the public right-of-way — while the City's Bureau of Environmental Services maintains the main. Replacement needs a city plumbing permit for the private side and a separate right-of-way permit if work extends into the ROW, plus 811 utility locates, inspection, and an as-built sign-off.
We pull every permit, coordinate locates and inspection, and submit the as-built so the job is fully legal and closed out.
Our replacement process
- Camera scope to confirm condition and method.
- Permits & 811 locates pulled and scheduled.
- Install by pipe bursting or open trench.
- Inspection, backfill & restoration, then city sign-off.

How much does sewer line replacement cost in Portland?
The price depends on diagnosis, access, parts and the agreed work. Ask what is included in the assessment and request the repair scope and price before authorizing work. Additional restoration or specialist work should be identified separately.
Trenchless or traditional dig — which is right for my line?
Trenchless pipe bursting saves your yard and is faster when the grade is sound. Open-trench is required when the pipe is bellied, fully collapsed, or the slope must be re-graded. We camera the line first, then recommend the method.
How long does a full sewer line replacement take?
The time depends on the fault, access, parts availability and the work agreed after diagnosis. Ask for the expected repair duration and any follow-up before approving the scope.
Who owns the sewer lateral in Portland — me or the city?
The property owner owns the lateral from the house out through the right-of-way to the main; the City (Bureau of Environmental Services) maintains the main. Private-side work uses one permit and right-of-way work another — we pull both as needed.
Do I need a permit to replace my sewer line in Portland?
Yes — a plumbing permit for the private side, plus a right-of-way permit if work extends into the ROW, with 811 locates, inspection, and an as-built sign-off. As an Oregon contractor we handle all of it.
Should I replace my Orangeburg sewer pipe?
Almost always yes. Orangeburg (tar-and-fiber, 1940s–70s) softens, blisters, and collapses with age and can't be reliably lined. Replacement with PVC or HDPE — often by trenchless pipe bursting — is the lasting fix.
Can a bellied or sagging sewer line be fixed with trenchless?
No — trenchless follows the existing path, so it leaves the low spot in place. A bellied line must be excavated and re-graded by open trench to restore proper slope and flow.
What is pipe bursting and how does it work?
A bursting head is pulled through the old pipe, fracturing it outward while pulling a new seamless HDPE pipe in behind — through just a small entry and exit pit. The new HDPE line is rated for ~50 years with almost no digging.
What are the signs I need a full replacement instead of a repair?
Repeated backups after cleaning, a collapsed section, multiple bad spots, Orangeburg pipe, severe root destruction, or a bellied line all point to replacement over a spot repair. A camera inspection confirms it.
My sewer scope failed during a home sale — can you help fast?
Yes — same-day scoping and a written, fixed-price replacement quote you can use to negotiate (repair before closing, credit, or renegotiate). Fast turnaround keeps your deal on track.

How the repair scope is decided
Planning establishes the route, relevant defects, connection points, accessible work areas and known utility conflicts. The property’s drainage needs and any shared connections must be understood before the scope is agreed.
Open excavation and available trenchless approaches have different access needs and limitations. A proposal should show which method is suitable, what sections are included and how the completed line will be checked.
Confirm the temporary loss of service, permits and inspection responsibilities, utility coordination and restoration limits. A replacement quote should not leave the final connection or surface repairs unclear.
What to have ready before a visit
Provide previous inspection reports and the locations of known cleanouts, easements or shared lines. Identify paving, walls, gardens and building access that may be affected by the work.
