(2025 Update) A sewer line replacement cost will probably stay in the ballpark of $2,300 to $10,000. The sewer line itself can cost between $200 per foot and $250 per foot. It all depends on the cost of materials used and the longevity of the labor needed for the job.
Cost Estimates
As we mentioned earlier, in the state of California, the cost of sewer line replacement can amount to anywhere between $50-$250 per linear foot, with an average of around $150.
In most cases, home insurance will cover sewer line damage from specific events. This includes extreme weather (excluding earthquakes and floods), vandalism, fire, and damage from vehicles or falling objects.
Trenchless sewer repairs, such as pipe lining or pipe bursting, are typically 30-40% less expensive than traditional excavation and less invasive. Traditional excavation, which involves digging a trench to access the damaged pipe, is usually more expensive and can cause significant damage to your yard.
If your sewer line is damaged, it could delay or even halt a possible sale. Even if you do sell the property, you could have to accept a lower price or make concessions. However, getting trenchless sewer line repair done can improve the value of your place.
Generally speaking, you're going to find that most main sewer lines will only last somewhere between 50 and 100 years before you need to do a main sewer line replacement. You could very well have a broken sewer line on your hands right now and not even realize it.
For instance, residential sewer line depth ranges from 18 to 30 inches. However, city sewer line depths are different. Your city's sewer lines must always be deeper than the deepest residential pipe to allow waste to flow downhill. As such, these lines can go as deep as needed.
Typically, to replace a sewer line it can take anywhere from 1 to 2 days, to 3 to 5 days. In some rare cases, it may even be as quick as one day. Generally, the estimated time frame will depend on the layout of your property, your home's piping system, and the depth required to excavate.

On the other hand, if you've got sewer problems or other urgent repairs, you really can't afford to wait, and financing definitely makes sense. You basically have three choices—a personal home improvement loan, a home improvement credit card, and a home equity loan.
As a general rule, sewer line repairs are considered to be standard home maintenance expenses, which means you are not eligible for a tax break on your personal income tax returns.
Expert Recommendations for Sewer Line Cleaning
We recommend homeowners schedule sewer line cleaning every 18 to 24 months to prevent buildup and clogs. Regular cleanings help avoid costly repairs and extend the life of your plumbing system.
Sewer line coverage varies in cost but can generally be obtained for $5 to $15 per month, depending on your property size and the area in which you live. Because sewer line incidents often cost upwards of $10,000 to repair, many homeowners consider sewer line coverage a good investment.
While it's certainly possible for a homeowner to replace the sewer line from the house to the street, it's not going to be an easy job. It's going to require both knowledge and manpower because it needs to be done right, or it won't work properly.
Average Cost:
Repairing or replacing a small section of drain pipe can typically run between $250 and $1,250. Repairing larger sections or breaks can run between $400 and $1,500, with that cost going higher based on complexity of the repair.
Sewer work is expensive because of the labor-intensive process involved, which includes excavation, pipe removal, and installation of a new one. It requires significant manual labor and expertise, driving up the overall cost.
Verdict: Both Mr. Rooter and Roto-Rooter offer a standard lineup of plumbing services, including emergency response. However, Mr. Rooter has an edge with more comprehensive water line, well pump, and sewer repair and replacement services.
Life Expectancy of a Sewer Pipe
Old homes, or homes built prior to 1980, will most likely have clay sewer pipes. Clay sewer pipe life expectancy is approximately 50 years. PVC pipe, which became more prominent after 1980, typically lasts longer – approximately 100 years.
Sewer Line Cost per Linear Foot
The average cost to install a sewer line ranges from $50 to $250 per linear foot. New pipes cost $3 to $80 per foot, with about $30 to $200 per foot for labor expenses. These pipes are typically buried in your yard, running from your house to the main sewer drain.
Sewer lines come in a variety of depths. They can range in depth from 12″ to 30″ and can be as deep as 6+ ft. Often, it's only a matter of the environment and climate.
The IPC and IRC also state that all water and sewer lines must be at least 6 inches below the typical frost level for the area to help ensure that the pipe can't freeze.
The septic tank is often buried about six feet deep and ten feet away from the building.
