Today, many sewer problems can be repaired using trenchless methods that minimize disruption to landscaping, driveways, patios, and other property features. However, trenchless repair is not always the right solution for every situation.
Understanding the differences between trenchless sewer repair and traditional sewer replacement can help you make an informed decision when facing a major sewer issue.
At McKee Brothers Plumbing and Rooter Inc., we help homeowners throughout Woodland, Davis, Sacramento, Winters, and surrounding communities determine the most effective and cost-efficient repair option for their specific sewer problem.
What Is Trenchless Sewer Repair?
Trenchless sewer repair is a method of replacing or repairing underground sewer lines without excavating the entire length of the pipe.
Instead of digging a large trench across the property, plumbers access the existing sewer line through limited entry points and use specialized equipment to repair or replace the damaged section.
One of the most common trenchless methods is pipe bursting.
Pipe bursting involves pulling a new sewer pipe through the old damaged pipe while simultaneously breaking apart the existing line. This allows the new pipe to take the place of the old one with minimal excavation.
Benefits of Trenchless Sewer Repair
Trenchless sewer repair offers several advantages for homeowners:
- Minimal disruption to landscaping
- Less damage to driveways and sidewalks
- Reduced excavation costs
- Faster project completion
- Long-lasting modern piping materials
- Less restoration work after repairs
For properties with mature landscaping, decorative concrete, irrigation systems, or other improvements, trenchless repair can significantly reduce the impact of a sewer replacement project.
What Is Traditional Sewer Replacement?
Traditional sewer replacement involves excavating the ground above the damaged sewer line to expose the entire pipe.
Once the pipe is exposed, the damaged section or entire line is removed and replaced with new piping.
Traditional excavation remains an effective solution and is sometimes necessary when trenchless methods are not feasible.
Although excavation is more disruptive, it allows plumbers to directly inspect soil conditions, identify additional issues, and completely replace severely damaged systems.
When Traditional Sewer Replacement May Be Necessary
Traditional excavation may be recommended when:
- The sewer line has collapsed
- There are multiple severe offsets in the pipe
- The pipe route needs modification
- Accessibility limitations prevent trenchless equipment use
- The sewer line is extremely shallow or unusually configured
- Additional underground utilities complicate trenchless installation
In these situations, excavation may provide the safest and most effective long-term repair.
How Do Plumbers Determine Which Method Is Best?
The first step is typically a sewer camera inspection.
A sewer camera allows plumbers to inspect the interior condition of the pipe and determine:
- The location of the damage
- The severity of the problem
- Whether roots are present
- Whether the pipe has collapsed
- Whether trenchless methods are viable
- The overall condition of the sewer system
Camera inspections help eliminate guesswork and ensure the recommended repair method is appropriate for the actual condition of the line.
Real-World Trenchless Sewer Repair Experience
McKee Brothers Plumbing has completed trenchless sewer repair projects throughout the Woodland area.
In one Woodland project, a homeowner was experiencing bathroom backups caused by a damaged sewer line. After evaluating the system, our team performed a 31-40 foot trenchless pipe bursting repair to replace the sewer line. Hydro jetting was also performed to clear the system and restore proper flow.
Limited excavation and concrete restoration were completed as needed, allowing the sewer system to be fully restored while minimizing disruption to the property.
You can view examples of completed sewer projects on our Plumbing Jobs page.
Cost Considerations
Many homeowners assume trenchless sewer repair is always less expensive than traditional excavation. In reality, costs vary depending on several factors.
Factors that influence sewer repair costs include:
- Length of pipe being replaced
- Depth of the sewer line
- Accessibility of the repair area
- Condition of the existing pipe
- Restoration requirements
- Concrete removal and replacement needs
- Permitting requirements
While trenchless methods may involve specialized equipment costs, they often reduce landscaping and restoration expenses that can accompany traditional excavation.
Can Trenchless Sewer Repair Prevent Future Problems?
Modern trenchless replacement methods typically utilize durable piping materials designed for long-term performance. New sewer lines can improve flow, reduce root intrusion risks, and eliminate many issues associated with aging clay, cast iron, or deteriorated sewer systems.
However, regular maintenance and inspections remain important for protecting any sewer system.

When Hydro Jetting May Be an Alternative
Not every sewer issue requires replacement.
In some cases, heavy grease buildup, scale accumulation, or root intrusion can be addressed through professional hydro jetting services.
A proper inspection can help determine whether cleaning the line is sufficient or whether repair or replacement is necessary.
