Sewer Line Repair Costs in 2026
Sewer line problems are among the most expensive plumbing repairs homeowners face. The good news: modern trenchless methods have dramatically reduced costs and disruption compared to traditional dig-and-replace.
Trenchless Sewer Repair
Pipe lining (CIPP) costs $1,500–$4,000 for a typical residential sewer line. A resin-coated liner is inserted into the existing pipe and inflated, creating a smooth new pipe inside the old one. It requires only 1–2 small access points — no digging up your yard.
Pipe bursting costs $2,000–$5,000. A new pipe is pulled through the old one, breaking the old pipe outward. This is used when the old pipe is too damaged for lining. It requires access pits at both ends.
Traditional Excavation
Digging up and replacing the entire sewer line costs $4,000–$15,000+ depending on depth, length, and landscaping. Add $2,000–$5,000+ for landscape restoration (re-sodding, driveway repair, etc.). This method is used when the pipe has completely collapsed or when trenchless is not feasible.
Factors That Affect Cost
- Pipe length: Residential sewer lines are typically 50–100 feet
- Depth: Deeper pipes cost more to access (especially with excavation)
- Pipe material: Clay and cast iron pipes are more prone to problems
- Obstructions: Lines under driveways, sidewalks, or trees cost more
- Permits: Most cities require permits for sewer work ($100–$500)
Signs You Need Sewer Repair
- Multiple drains backing up simultaneously
- Sewage smell in yard or basement
- Unusually green or soggy patch in yard

Related Questions
Does homeowner's insurance cover sewer line repair?
Standard homeowner's insurance typically does NOT cover sewer line repair — it is considered maintenance. However, many insurers offer sewer line coverage as an add-on for $5–$15/month. Some utility companies also offer sewer protection plans. Check your policy before you need it.
How long does sewer line repair take?
Trenchless repair (pipe lining or bursting) typically takes 1–2 days. Traditional excavation takes 3–5 days plus additional time for landscape restoration. Emergency temporary repairs can often be done same-day.
How long do sewer line repairs last?
Trenchless pipe lining (CIPP) is rated for 50+ years. New PVC pipe (via excavation or pipe bursting) lasts 75–100 years. Both methods carry long warranties — ask your plumber about their specific warranty terms.
