Sewer line problems? Skip the digging and save your yard
Fix pipes without the mess of excavation!
No dig sewer line repair offers a smarter way to restore damaged pipes without tearing up your lawn, driveway, or landscaping. Using industry-leading CIPP (Cured-In-Place Pipe) lining technology, repairs are done underground with minimal disruption to your property. That means faster service, lower overall costs, and a long-lasting solution that keeps your sewer system flowing smoothly.
Trenchless Sewer Repair Solutions
Sewer relining is a modern method of repairing underground sewer pipes without replacing the entire system or excavating your lawn. Sewer Ninjas delivers efficient no-dig sewer repair with minimal disruption to your property.
Traditional sewer replacement can take weeks and leave behind expensive restoration costs. Trenchless sewer relining can often be completed in as little as one to two days.
Signs You May Need Sewer Line Repair
If you notice any of the following, it may be time to schedule a sewer inspection:
- Clogged, gurgling, or slow drains
- Sewage odors
- Wet spots in the yard
- Frequent drain cleaning needs
- Foundation settlement near sewer lines
- Tree roots invading sewer pipes
Our No-Dig Sewer Relining Process
Our trenchless sewer relining technology restores damaged sewer pipes without the major excavation associated with traditional sewer replacement methods.
1. Video Inspection
We begin with a detailed sewer video inspection to identify cracks, root intrusion, offsets, or damaged sections.
2. Sewer Line Cleaning
Our team thoroughly cleans the sewer pipe to remove roots, buildup, grease, and debris before lining begins.
3. Preparation
Using advanced robotic cutting equipment, we remove buildup and obstructions to prepare the pipe for a smooth installation.
4. CIPP Sewer Liner Installation
A flexible epoxy resin-coated liner is inserted into the damaged sewer pipe and inflated. The liner molds tightly to the inside of the existing pipe as the resin cures in place.
5. Final Inspection & Flow Testing
Before we begin relining the pipe, clogged drains are thoroughly cleaned to remove debris, roots, buildup, and obstructions that could interfere with the liner installation.
6. Maintenance & Warranty
We recommend routine annual drain cleaning and to extend the life of your sewer system. Qualified sewer relining projects also include a 15-year transferable warranty.
The Robotic Advantage: Precision Reinstatements
We utilize the IMS Robotic Cutter to ensure a “no-compromise” finish on every lining project.
- Flawless Flow: We use robotic precision to grind out lateral openings to their original diameter, ensuring 100% flow recovery without damaging the new liner.
- Obstacle Removal: Before lining, our robot grinds away protruding taps, mineral deposits, or hardened concrete that would otherwise prevent a perfect seal.
- Precision Restoration: While others “punch a hole,” we use surgical robotic precision to restore your system to full capacity.

Testimonials
Hear why Wisconsin homeowners and businesses trust Sewer Ninjas for no-dig sewer repairs that last.
In both the initial assessment and the actual work, the guys came in quickly and effectively got the work done. they were very open to sharing what they were doing and answering all my questions. I thought this was really important since most homeowners (like me) don't know how their sewers work and need to trust the people doing the work.
Fantastic business. Owner Eric really knows his stuff and tech Jeff as well who is always on time professional and easy going. I’ve worked with them multiple times as a homeowner and realtor. Always my first recommendation. Sure… things can get expensive but you wouldn’t complain about a roof costing 10k so why complain about getting you SEWER fixed?? 10/10
We were referred to Sewer Ninjas by Milwaukee Drain Company after discovering we needed our sewer cleaned—but quickly realized we didn’t have an access point due to the old plumbing in our Milwaukee bungalow. Even though our first appointment had a hiccup, Jeff stepped in immediately, resolved the issue, and truly went above and beyond to make things right. He was professional, thorough, and incredibly helpful throughout the entire process. Sewer Ninjas turned a frustrating situation into a smooth, stress-free experience. We’ll definitely be working with them again in the future—top-notch service and a great partner to have on your side!
After unsuccessful snaking, this company was recommended, and I could not be happier. From the after hours call the owner made to us to the actual sewer line clean out, these workers are professional and respectful of the home they are in. Everything was fully explained, and the work site mess was at an absolute minimum. They said they would get it open or be able to show why not and were men of their word, issue solved and pipe open as they said they would do. Would not hesitate to recommend this company, fast, quality work, a rarity these days.
Sewer Ninjas is an honest company that strives to provide the best work possible for their customers. We had a series of tree roots growing through our sewer line, and the team scheduled an appointment quickly and removed them. They documented everything with video which made the insurance claim very easy. We also had them reline the existing pipe, and while that process did have a few hiccups, the team returned multiple times to correct the issues and ensure the job met their standards. This definitely impacted the profitability of the job, but Sewer Ninjas prioritized job quality and the long-term health of our home. They offer a strong warranty, and given my experience, I have no doubt they will stand behind it if future issues arise. Would highly recommend to anyone.
Sewer Ninjas Q&A
A flexible liner coated with epoxy resin is inserted into the damaged sewer pipe. Once inflated and cured, it creates a seamless new pipe inside the old one—essentially giving your sewer line a brand-new interior.
A bursting head is pushed through the old pipe while simultaneously pulling a new, durable replacement pipe into place. This method replaces severely damaged or collapsed lines without digging long trenches.
Homeowners are strong candidates for no dig sewer line repair if their pipes are damaged but still structurally stable enough to support a liner or replacement. Typical situations include:
Cracked or Leaking Pipes – caused by age, shifting soil, or corrosion.
Root Intrusion – tree roots breaking into sewer lines through small gaps.
Minor Collapses or Blockages – where the line is still accessible for repair.
Pipes Under Landscaping or Hard Surfaces – when digging would be costly or disruptive (lawns, driveways, patios).
Older Homes – especially those with clay, cast iron, or Orangeburg pipes prone to deterioration.
Trenchless repair may not be ideal if the pipe is completely collapsed or too deteriorated to support relining—in those cases, full excavation might still be required.
The Sewer Ninjas team follows a thorough, proven process: begin with a video inspection, clean the pipe, apply a resin-coated liner, and cure it into a seamless new pipe. Backed by NASSCO-certified professionals, the repair comes with a transferable warranty, giving you confidence and peace of mind.
We are also a local, family-owned company deeply rooted in Wisconsin communities—we're licensed, bonded, insured, and committed to honest, high-quality work. Our mission emphasizes safety, integrity and top-tier customer service. We are proud of our local reviews!
