Sewer Pipe Lining (CIPP) in Duluth, MN

The offer

Sewer Pipe Lining (CIPP) in Duluth, MN

Sewer lining is used when a pipe has multiple defects but is still structurally suitable for rehabilitation.

The process begins with a detailed camera inspection and extensive cleaning of the existing sewer line. Specialized cleaning equipment removes roots, buildup, burrs, and debris to prepare the pipe for lining.

Once cleaned, a custom liner is measured, cut, and saturated with epoxy resin. The liner is installed through an inversion process that presses it tightly against the existing pipe walls. A calibration tube ensures the liner conforms to the exact shape and diameter of the host pipe.

After installation, a blue-light curing system is pulled through the sewer line to harden the epoxy and create a new seamless pipe within the old pipe. Any branch connections are reopened using robotic cutting equipment, and a final camera inspection verifies the quality of the installation.

The result is a structurally sound sewer line with minimal excavation and significantly reduced restoration costs.

Repair the line

Install a new pipe inside the existing pipe.

When a sewer line still maintains its general shape and alignment, CIPP lining allows us to install a new structural pipe inside the existing one. The result is a seamless, root-resistant pipe designed to provide 50+ years of service while avoiding major excavation and preserving your yard, driveway, landscaping, and hardscapes.

CIPP lining is the right choice when:

✓ The pipe retains its round shape, but has cracks, root intrusion, or moderately separated joints.

✓ The line is clay tile, cast iron, PVC, Orangeburg, or other pipe material that is not collapsed.

✓ The client is taking a proactive approach, and repairing the line before an issue occurs.

What you should know:

✓ CIPP lining creates a new structural pipe inside the existing pipe.

✓ The finished liner is seamless and resistant to roots and joint separation.

✓ Properly installed CIPP liners provide an expected service life of 50+ years.

Common in Duluth, MN: Many older clay tile lines from pre-1950s homes, cast iron, and even Orangeburg sewer lines can be successfully rehabilitated with CIPP lining when the pipe has not collapsed.

Replace the line

New pipe. Minimal excavation whenever possible.

When a sewer line has lost its shape, contains major bellies, or is completely collapsed, replacement becomes the better option. Our first choice is typically pipe bursting because it allows us to install a completely new pipe while minimizing disruption to the yard.

Replacement is the right choice when:

✓ The pipe is fully collapsed and a camera or cable cannot pass through.

✓ A major belly or sag is causing standing water and recurring backups.

✓ The line has severe deformation that cannot support a structural liner.

✓ The pipe route or elevation must be corrected.

✓ Existing defects prevent successful CIPP installation.

How we replace sewer lines:

✓ Pipe Bursting – A new pipe is pulled through the existing line while breaking apart the old pipe underground.

✓ Typically requires excavation only at the city connection, not a trench through your yard.

✓ Preserves most landscaping and causes far less disruption than traditional trenching.

✓ Installs a completely new sewer pipe with a 50+ year life expectancy.

Traditional excavation is only necessary when:

✓ The pipe is completely collapsed and inaccessible.

✓ A major belly requires regrading of the sewer line.

✓ Site conditions prevent pipe bursting.

Common in Duluth, MN: Orangeburg sewer lines in post-war homes built between 1945 and 1965 can deform or collapse and are often addressed with pipe bursting or replacement.

Common questions

Frequently asked questions

Is CIPP sewer lining as good as installing a brand new pipe?

Yes. The CIPP liner is the same thickness as a schedule 35 PVC pipe. It is not a lesser product. The only reason we would choose a different method is if the pipe cannot physically hold a liner, not because lining is a compromise.

What pipes can be lined in Duluth, MN?

Most pipes can be lined including clay tile, cast iron, concrete, and PVC. The pipe needs to hold its basic form. A liner can even bridge sections where pipe material is missing, as long as it can reach the next intact section.

When is lining NOT the right option?

When the pipe is collapsed, when there is a major belly or sag that would trap water in the liner, or when the connection at the street main requires excavation anyway. In those cases bursting or a hybrid approach is the better call.

How long does sewer pipe lining take?

Most residential jobs in Duluth are completed in a single day. We clean the line, pull the liner through, cure it with UV light, and run a final camera pass to confirm before we leave.

How much does sewer pipe lining cost in Duluth, MN?

Most residential sewer lining projects range from $5,000 to $15,000 or more depending on line length, pipe material, and access. We confirm final pricing before any work begins.

What is the warranty on sewer pipe lining?

We include a 10-year warranty. The liner itself has a 50-year design lifespan.

Great crew, very professional work, five 🌟 they're there when they say they're going to be there. no excuses, anything goes wrong they fix it. customer service is five star. I would call them to get the job done. I highly recommend them. Had my sewer line replaced. Everything went smoothly. Loved working with this crew/company. They made an ugly situation beautiful once again.

Contour was very accommodating with all the home owners insurance issues I had to sort out. They repaired my main sewer pipe (had several cracks in it) with a 50 year warranty liner. Contour's quote was half of ASP as they found a closer access point to the front of the house and inspected all my home pipes determining they were fine and did not need lining. They save people a lot of money by only lining the sq foot of pipes that need it. The crew were very polite and professional. Would definitely recommend and hire them in the future for other services.

Contour Inc. Was able to fix my sewer in a very timely manner so we could sell our house. They dug it up even in February! Very nice to deal with them.

From my initial conversation with Jason to my sewerlining appoint with Troy and his crew, Contour was 5 stars across the board. Everyone I spoke to was professional, knowledgeable, and patient throughout the process. They made it easy in addition to quoting a reasonable price. I would highly recommend anyone in the market for a sewerlining to consider their services.

Contour came out and was willing to work with us on a solution that would fix a leak in a very difficult water main leak. They worked quickly, professionally, and cleanly.

They were able to complete the work faster than expected, and did a great job. We really appreciate their flexibility and ability to get the job done!

Contour is the best! Everyone treats you like an equal human and they are super knowledgeable at what they do. Brian and Co. were kind and honest from the start and very responsive. Everything was done very well and efficiently. They even came back to check on the project and touch up the blacktop they needed to patch in the alley after the job was completed. (Sewer line repair) Really appreciate you! I look forward to working with you again soon, just hopefully on an elective project and not an emergency. ;)

This is a very professional company. Not only did they actually return my request for a quote, they did it rapidly. The inspection was very thorough and was easily done. The quote was very fair, and the installation was amazing! The day of install we made room for their work, and when they left, it was cleaner than when we moved all our stuff! The workers communicated with us during the install, there was never a question about anything. Work was professional, and the out come is a sewar line I won't have to worry about again!

Thanks Contour!
