Complete Sewer Line Replacement
No homeowner wants to hear that their main sewer line needs to be completely replaced. However, when pipes made of older materials like clay, cast iron, or Orangeburg reach the end of their lifespan, patching them is no longer viable. Severe ground shifting, total structural collapse, or massive root webs that have crushed the line require a full system replacement to restore safety and sanitation to your home.
The replacement process has evolved significantly. While traditional open-trench excavation is still used (and sometimes required for severely sloped or collapsed lines), trenchless technologies like pipe bursting can often replace the entire line with minimal digging. By pulling a seamless, high-density polyethylene (HDPE) pipe through the old line, we can provide a durable, root-resistant sewer system designed to last for decades.
Signs You Need Sewer Line Replacement
- The pipe has completely collapsed and a camera cannot pass through.
- Your home has Orangeburg or deeply corroded cast iron pipes that are actively failing.
- Repairs have become a frequent, recurring expense that outweighs the cost of replacement.
- Massive tree root intrusion has shattered the existing pipe beyond repair.
- The pipe has a severe "belly" or sag that causes constant standing water and blockages.
Our Process
Comprehensive Inspection
A final camera inspection and precise locating are performed to map the exact path and depth of the existing line.
Method Selection
Based on the pipe's condition and surrounding landscape, the best method (trenchless vs. excavation) is determined.
Excavation or Bursting
Trenches are dug, or access pits are created to pull the new bursting head and HDPE pipe through the old line.
Connection and Backfilling
The new line is connected to the city main and the house, inspected by the city, and the ground is restored.
What Affects the Cost
- The replacement method chosen (trenchless pipe bursting often saves landscaping costs but requires specific equipment).
- The total linear footage of the new pipe required.
- Depth of the line, as deeper pipes require significant trench shoring and safety equipment.
- Obstacles like driveways, retaining walls, or large trees in the path of the replacement.
- City permits and the cost of tapping into the municipal main.
✓ Safe to DIY
- Reviewing multiple replacement options (trenchless vs. traditional) with your plumber.
- Preparing the yard by moving movable landscaping elements before the crew arrives.
✕ Stop & Call Us
- Attempting any part of a main sewer replacement yourself. This requires heavy machinery, specialized training, and strict adherence to municipal codes.
Frequently Asked Questions
How long does a sewer line replacement take?
Most residential sewer line replacements can be completed in 1 to 3 days, depending on the length of the line, the method used, and whether extensive excavation is required.
What is pipe bursting?
Pipe bursting is a trenchless method where a cone-shaped tool is pulled through the old pipe, shattering it outward, while simultaneously dragging a brand-new, seamless pipe into place behind it.
Will replacing my sewer line destroy my yard?
If traditional excavation is required, there will be a trench dug. However, if your line is a candidate for trenchless replacement, we only need to dig two small access holes, leaving the rest of your lawn and driveway intact.
