Sewer Line Replacement
When a sewer line is too far gone for repair — widespread cracks, repeated root intrusion, or a collapsed section — replacement becomes the more reliable long-term choice. Replacement removes the recurring problem rather than patching it.
Common reasons you may need this service
- The line has failed in multiple places.
- Repairs haven't held and clogs keep returning.
- An older line is collapsing or heavily root-invaded.
- A renovation requires rerouting the waste line.
- An assessment recommended replacement.
Typical tasks and considerations
- Assessing the full length of the line.
- Planning the replacement route and connections.
- Removing the failed section and installing new line.
- Reconnecting to the city connection and fixtures.
- Testing flow and sealing the system.
Common problems and possible causes
Aging cast iron or clay
Older materials corrode or crack over decades. Modern replacements use durable PVC that resists roots and corrosion.
Collapsed section
A collapse can't be cleared — the line must be replaced. Catching it early limits the excavation needed.
Repeated root intrusion
When roots return after each clearing, the entry points are the issue. Replacing that section removes the openings.
