Sewer Line Replacement in Portland, OR
Trenchless and traditional replacement options from the team Portland has trusted for over two decades.
When Repair Is No Longer Enough
Some sewer lines are too far gone for a patch or a liner. Collapsed sections, severe root damage, and pipes that have deteriorated beyond their useful life all call for a full replacement. Many Portland homes built before the 1980s still run on original clay or cast iron laterals that were never designed to last this long.
Our team starts every project with a sewer camera inspection so you can see exactly what is happening underground. No surprises, no upselling.
Sewer Line Replacement Options
We offer two approaches and recommend whichever one fits your property and budget best.
- Trenchless Pipe Bursting: A new HDPE pipe is pulled through the old line, breaking it apart as it goes. Minimal yard disruption and a finished product that lasts 50 years or longer. See our trenchless services for details
- Traditional Excavation: For lines with severe offsets, sharp bends, or extreme depth, open-trench replacement gives us full access to install the new pipe correctly
- Video Inspection and Planning: Camera footage guides every decision so we choose the right method from the start
What to Expect During the Project
Most residential sewer line replacements wrap up in one to three days. Trenchless jobs often finish within a single day. We handle the permit process, perform the work, backfill and compact the trench, and restore the surface. You get a clear timeline and written estimate before we start.
For less severe damage, our sewer line repair services may be a more cost-effective option.

One to three days for most residential properties. Trenchless replacements are often done in a single day.
Will replacing my sewer line tear up my yard?
Trenchless methods only require small access pits. Traditional excavation involves trenching, but we restore the surface when the work is done.
What kind of pipe do you install?
We use high-density polyethylene (HDPE), which resists corrosion and has a lifespan of 50 years or more.
Do I need a permit to replace a sewer line in Portland?
Yes. A plumbing permit is required in most jurisdictions. We take care of the paperwork for you.
