Trench vs. trenchless
Traditional trench
A backhoe digs along the full length of the line, the old pipe comes out, and new PVC goes in. It works for any pipe condition, including collapsed or badly sagging lines. The dig, and rebuilding what was on top of it, is what makes it expensive.
Pipe bursting
A bursting head is pulled through the old pipe from one small pit to another. It breaks the old pipe outward and drags a new HDPE pipe in behind it. It needs two access pits and works even when the old pipe is badly cracked.
Pipe lining (CIPP)
A resin-soaked liner is inverted into the old pipe and cured into a new pipe inside the old one. It needs only one access point but cannot fix a collapsed or badly sagging line, and it slightly reduces the pipe diameter.
What drives the price
- Length and depth. Deep lines need shoring and much more digging.
- What is on top. Driveways, sidewalks, trees, and landscaping add restoration cost to trench work.
- Pipe condition. Collapsed or bellied pipes may rule out lining.
- Street work. Connections at the main can need traffic control and street patching.
- Permits and inspections. Required almost everywhere.
Get the camera video. Ask for the inspection recording and the footage markers of each problem. It lets other plumbers quote the same job and keeps the scope honest.
Frequently asked questions
How much does it cost to replace a sewer line?
A typical 60-foot sewer line replacement costs about $4,850 – $17,500 by traditional trench. Trenchless methods cost more per foot but save on digging and restoration. Lines under driveways, deep lines, and street connections can push the total past $25,000.
Is trenchless sewer replacement cheaper?
Per foot, trenchless usually costs more. In total it is often cheaper when the line runs under a driveway, patio, mature trees, or finished landscaping, because there is little to restore afterward.
Does homeowners insurance cover sewer line replacement?
Standard policies usually do not cover wear, tree roots, or corrosion. A sewer line or service line rider, often $30–$100 a year, can cover it. Some utilities also sell service line warranties.
Who pays for the sewer line, the homeowner or the city?
In most U.S. cities, the homeowner owns the lateral from the house to the city main, sometimes including the part under the street. Check with your local utility.
How do I know if my sewer line needs replacing?
Repeated backups, gurgling drains, sewage smell in the yard, soggy or unusually green patches of lawn, and slow drains throughout the house. A camera inspection costing $150–$500 confirms it.
Can a sewer line be repaired instead of replaced?
Often yes. A single cracked or root-blocked section can be spot-repaired for $1,000–$4,000. Lining can also rehabilitate a line that is cracked but still round.
