Cured-in-place lining
A resin-soaked liner is pulled or inverted into the old pipe and cured in place, forming a new pipe inside the old one that seals cracks and root entry points.

How it works
Fixing a Sewer Line Without Digging a Trench
Trenchless methods repair or replace a sewer line from one or two small openings instead of a trench along the whole route. That matters when the line runs under a driveway, patio, mature tree or finished landscaping that would cost a lot to rebuild.
Not every line qualifies. A collapsed pipe or a long sag usually needs digging, so we check the line first and tell you plainly if trenchless will work. If it won't, we'll cover your other options for sewer repair in Portland.
Before the liner goes in
Cleaning and Prep Come First
A liner only bonds to clean pipe, so roots, grease and scale are cleared out with high-pressure water before anything goes in.
We also measure the run, check every joint and locate branch connections that have to be reopened after lining.
Two methods
Sewer Pipe Lining and Pipe Bursting
Pipe bursting
A bursting head pulls new pipe through the old line and breaks the old pipe outward as it goes. It suits badly worn pipe that still follows a straight path.
Which one fits
Lining keeps the pipe's existing path; bursting can step up the pipe size. The line's condition decides.
Cost
Trenchless vs. Digging: Cost Compared
Trenchless replacement and lining usually cost $60 to $250 per foot, about the same per foot as an open trench.
The savings come afterward: no new driveway, patio or landscaping to pay for. You get the exact price before work starts.

- Step01
Check the line
We confirm the pipe can be lined or burst and measure the run.
- Step02
Clean
The pipe is cleared so the liner can bond or the bursting head can pass.
- Step03
Install
The liner is set and cured, or new pipe is pulled through between the two access pits.
- Step04
Reopen connections
Any branch lines covered by the liner are cut back open from inside the pipe.
- Step05
Close up
We confirm the line is flowing, fill the pits and tidy the site.
Is it right for you?
Is Trenchless Right for Your Line?
Can every line be lined?
No. Collapsed sections, severe sags and some badly offset joints have to be dug and repaired first.
How long does a liner last?
Cured-in-place liners are designed for a long service life and resist the root intrusion that ruins old joints.
Can I use my drains during the work?
Not while the liner cures or the new pipe is being connected. The line is back in service as soon as it's reconnected.
Is trenchless always cheaper?
Per foot it's about the same as digging. It usually works out cheaper when there's a driveway, patio or mature landscaping over the line.
