Trenchless sewer line replacement doesn’t always mean your old system was trenchless. Therefore, there are several factors to consider when you try to estimate the price you’ll pay to replace your sewer system.
Sewer line replacement costs $2,900 on average for traditional piping methods. However, trenchless systems tend to cost more, and the distance your sewer line needs to travel to get to the street is the greatest cost factor you must consider. Even ten extra feet could add thousands of dollars to the price you pay.
Sewer line lengths vary greatly, but average between 50 and 75 feet. Below you’ll find some price ranges that could help you estimate your costs.
| Sewer Line Length in Linear Feet | Average Replacement Cost |
|---|---|
| 25–35 | $1,500–$8,750 |
| 35–45 | $2,100–$11,250 |
| 45–55 | $2,700–$13,750 |
| 55–75 | $3,300–$18,750 |
| 75–100 | $4,500–$25,000 |
I had an extremely positive experience with Fresno Plumbing. Six and one half years after I purchased my brand new home I had a sewer backup problem. I called the builder to see if there was any warrantly coverage and they referred me to the original plumber for my home, Fresno Plumbing and Heating. Fresno Plumbing and Heating said very rarely there are pipe connection problems and they would investigate. They videoed my sewer line, discovered a flaw in the pipe connection, used their sophisticated diagnostic equipment to determine the exact location of the problem, got all the necessary permits, identified all the nearby utility lines, and took responsibility for fixing the pipe at no charge to me. They could have said I was out of the warranty period, but they felt the problem could have dated to the original construction. They took my problem seriously and investigated. If I had to pay for this myself it would have cost thousands. I am very grateful for their honesty, for the repairs they made, and for the way they treated me in this situation. They were a strong advocate for me in dealing with the various player to get the repairs made at no charge to me.
Trenchless sewer systems require so little digging because they can be installed directly into your existing system, trenched or not, so long as it’s not severely damaged.
Replacing an old sewer system with a trenchless one requires a professional to blow a resin-coated lining through the old pipe. Sewer pipe lining costs between $135 and $150 per linear foot.
If you’re replacing an old sewer line that isn’t trenchless, a professional will also need to burst the existing pipe to make room for the new one. (The process doesn’t involve chemicals or anything that would ruin your soil or damage a garden or lawn; the old pipe is simply broken into small pieces.)
Pipe bursting (along with the lining) costs $150 to $190 per linear foot.
Whether you’re replacing or installing a brand-new trenchless sewer line, very little excavation is required. Still, you may need to do minor digging at the street and where the sewer line enters your home. You might also need to remove obstacles, such as tree roots that have grown over your old sewer line, which would require additional excavation.
Additional labor like this will cost anywhere from $60 to $250 per hour.
Permits can be costly when dealing with sewer lines. Getting one for a trenchless system could cost up to $1,000, depending on where you live. DIYing this task may not be an option in some areas due to local laws, so factoring in permit costs is non-negotiable. (Sorry to be the bearer of bad news.)
If your sewer system is complex and you need multiple lines connected to the main one going to the street, tie-ins could cost extra. The same per-linear-foot range ($60 to $250), plus any excavation that’s needed, will apply for these connections.
What else should you consider when replacing a trenchless sewer line? Here are some additional factors that could come into the mix with your project.
Additional plumbing from your local sewer company may be needed to set your trenchless sewer replacement up properly if you’re adding a new sewer line (or tie-in lines) to your home.
Installing or replacing plumbing costs $1,200 on average, though the price can vary greatly depending on the job.
Certain cities and counties don’t mess around when it comes to sewer line replacements. On top of obtaining a pricey permit, you may also be required to pay an inspector to ensure the job was done properly.
Sewer line camera inspection costs between $175 and $350. Longer sewer lines will cost more as they take longer to inspect.
In some cases, your trenchless sewer line might not be replacing your old sewer line, but a septic system. If you’re making the switch, you’ll have to pay for septic tank decommission, which includes shutting off your septic tank and having it removed.
This process can cost up to $5,500, including removal. It likely won’t cover the cost of additional landscaping needed in your yard afterward, though.
Installing a backflow preventer to ensure nothing nasty finds its way back into your home’s pipes is almost always recommended by sewer line professionals. Adding one will cost anywhere from $150 to $1,150, which includes parts and labor.
Hiring a professional trenchless sewer line installer may cost more upfront, but you benefit from faster completion, minimal property disruption, and a durable, long-lasting repair. Professionals use specialized equipment and proven techniques, helping you avoid costly mistakes and future sewer issues.
Trenchless sewer line piping is a highly technical process that requires experience, precision, and the right equipment. Here are some of the top reasons to work with a pro:
Trenchless sewer professionals ensure existing pipes, utilities, landscaping, and surrounding structures aren’t damaged during the process.
They have the specialized tools and training needed to properly assess pipe conditions, install liners or replacement pipes, and ensure proper flow and sealing.
Working with a professional ensures the new sewer line is installed correctly, meets local codes, and reduces the risk of leaks, backups, or premature failure.
Bundling trenchless sewer line piping with inspections, cleanouts, or pipe descaling services can help lower overall project costs.
Still, there are some ways to stretch your dollars when it comes to sewer line replacement. Consider these four money-saving tips when you replace your trenchless system:
Check your warranty: Some home warranties cover sewer line repair, saving you money over a replacement.
DIY the landscaping: Hourly rates for landscapers range from $50 to $100, so if you’re a confident DIYer, you could save money here after the main job is done.
Compare quotes: Always compare quotes from reputable contractors to make sure you’re getting the best overall value.
Don’t cut corners: When replacing your sewer pipe lining, do everything by the book so that you avoid costly disasters and expensive fines.
Be prepared to discuss with a pro the condition, age, and material of your existing sewer line, as these factors influence the trenchless method, timeline, and overall cost.
If your budget allows, ask your pro about optional services such as pipe lining upgrades, cleanout installation, or post-project camera inspections.
Make sure the work area is accessible and that utilities or landscaping features are clearly identified, since trenchless equipment still requires entry and exit points.
Plan for potential unexpected costs, including additional repairs if hidden blockages, root intrusion, or collapsed sections are discovered during the process.
