Sewer Pipe Lining Cost Per Foot
June 8, 2026
Go back to "Blog"
Sewer pipe lining has become one of the most popular trenchless sewer repair methods because it allows damaged pipes to be restored without extensive digging. Instead of excavating your yard, driveway, or landscaping, a durable liner is installed inside the existing sewer pipe, creating a strong new pipe within the old one.
If you’re wondering how much sewer pipe lining costs per foot, most homeowners can expect pricing between $80 and $250 per linear foot. However, the final cost depends on several factors, including the pipe’s diameter, condition, accessibility, and the total length being repaired.
In this article, Blue Boxer Plumbing explains what determines sewer pipe lining costs, why prices vary from project to project, and whether trenchless pipe lining is worth the investment.
1. What is sewer pipe lining?
Sewer pipe lining is a trenchless repair method that restores existing sewer pipes by installing a resin-saturated liner inside the damaged pipe. Once the liner is inflated and cured, it hardens into a seamless new pipe that can last for decades.
Sewer pipe lining is commonly used to repair:
- Cracked sewer lines
- Aging cast iron pipes
- Clay sewer pipes
- PVC sewer lines with minor damage
- Root intrusion
- Corroded drain pipes
Because the existing pipe remains in place, most projects require little or no excavation.
2. What is the average sewer pipe lining cost per foot?
Most sewer pipe lining projects cost between $80 and $250 per linear foot. The price per foot generally decreases on longer projects because some equipment and setup costs remain the same regardless of pipe length.
Typical project costs include:
- 20-foot repair: $2,000 to $4,000
- 40-foot repair: $3,500 to $6,500
- 75-foot repair: $6,000 to $10,000
- 100-foot repair: $8,000 to $15,000+
These figures are general estimates, and the actual price depends on the unique conditions of each sewer system.
3. Why does the price per foot vary?
Not every sewer pipe lining project is the same. Several variables influence the total cost.
- Pipe diameter
- Length of pipe being repaired
- Severity of corrosion
- Amount of root intrusion
- Number of bends and connections
- Accessibility of the sewer line
- Cleaning and preparation required
A severely damaged pipe often requires more preparation before the liner can be installed, increasing the overall project cost.
4. Does sewer pipe lining save money?
Although sewer pipe lining may appear expensive at first, it often costs less than traditional excavation when restoration expenses are considered.
Traditional sewer replacement may require:
- Digging up lawns
- Removing driveways
- Breaking sidewalks
- Excavating patios
- Repairing finished basements
- Restoring landscaping
Trenchless sewer lining minimizes property damage, which can save homeowners thousands of dollars in restoration costs.
5. How long does sewer pipe lining last?
Modern sewer pipe liners are designed for long-term performance. Most professionally installed liners are expected to last 50 years or longer.
The seamless interior helps protect against:
- Corrosion
- Rust
- Small cracks
- Minor root intrusion
- Water infiltration
The smooth interior surface can also improve wastewater flow and reduce future blockages.
6. When is sewer pipe lining a good option?
Pipe lining works best when the existing sewer pipe still has enough structural integrity to support the new liner.
It is commonly recommended for:
- Cracked pipes
- Minor leaks
- Corrosion
- Root intrusion
- Joint separation
- Aging sewer lines
If the sewer line has completely collapsed or has severe structural damage, excavation and replacement may still be necessary.
7. How do plumbers calculate the cost?
Before providing a quote, plumbers typically perform a sewer camera inspection to evaluate the condition of the line.
The inspection helps determine:
- Total pipe length
- Pipe diameter
- Amount of cleaning required
- Location of damage
- Accessibility
- Whether the pipe can safely be lined
After the inspection, you’ll receive a customized estimate based on the specific needs of your sewer system.
8. Is sewer pipe lining worth the investment?
For many homeowners, sewer pipe lining offers an excellent balance of durability, convenience, and long-term savings.
Benefits include:
- Minimal excavation
- Faster installation
- Long-lasting repairs
- Reduced property damage
- Improved sewer flow
- Lower restoration costs
Although the initial investment may be higher than a temporary repair, lining often prevents future problems and extends the life of the sewer system for decades.
9. Sewer pipe lining versus sewer replacement
Both repair methods have their place. Sewer pipe lining is ideal when the pipe is damaged but still structurally stable. Full replacement is generally recommended when the pipe has collapsed or cannot support a liner.
Replacement may be necessary if:
- The sewer pipe has collapsed
- Large sections are missing
- There is severe misalignment
- The pipe has extensive structural failure
- The existing pipe cannot safely hold a liner
A professional inspection will determine which option provides the best long-term solution.
