How Much Does Sewer Line Repair Cost in 2026?

Sewer line repair is priced by the foot, and the method matters as much as the damage. Cost researchers at HomeAdvisor and This Old House both put the national average at about $3,300, with most repairs landing between $1,400 and $5,300. Full-line replacement runs higher — HomeGuide's replacement-weighted data averages $6,000, with typical projects between $2,000 and $10,000. One number every major source agrees on: expect $50–$250 per linear foot depending on method and access.

Sewer Line Repair Cost at a Glance

Figures reflect 2025–2026 cost data published by Angi, HomeAdvisor, This Old House, and HomeGuide. Permits add $30–$500 depending on your municipality.

Cost by Repair Method

Spot Repair — $600–$1,050

When a camera inspection shows damage confined to one section — a single crack, a bad joint, one root intrusion point — a spot repair replaces or seals only that stretch. It's the least expensive fix and often wraps up in a day.

Trenchless Pipe Lining (CIPP) — $80–$250 per foot

A resin-saturated liner is inserted through an access point and cured in place, creating a new pipe inside the old one. No trench, minimal surface disruption. The per-foot price is the highest of any method, but there's little to nothing to restore afterward.

Pipe Bursting — $60–$200 per foot

A bursting head breaks the old pipe apart while pulling a new pipe through the same path. Like lining, it needs only entry and exit pits — a common choice when the old pipe is too collapsed to accept a liner.

Open-Trench Replacement — $50–$200 per foot

The traditional dig-and-replace. The per-foot rate looks cheapest, but the totals grow with what sits above the pipe: excavating under a slab adds $300–$350 per foot per HomeAdvisor, trenching through concrete runs $150–$200 per square foot per Angi, and lawn or driveway restoration is billed on top. That math is why trenchless methods often win on total cost despite the higher per-foot rate.

Cost by Length of Pipe

Most residential sewer laterals run 20–50 feet from the house to the city main, which is why so many quotes land in that $1,000–$10,000 middle band.

Factors That Affect Cost

• Repair method — trenchless costs more per foot but can save thousands in restoration
• Length and depth of the damaged run — per-foot pricing dominates the bill
• What's above the pipe — open lawn is cheap; slabs, driveways, and mature landscaping are not
• Pipe material — replacing cast iron or clay costs more than PVC
• Permits and inspection — $30–$500 for permits, $100–$500 for the camera work

What Homeowners Pay by City

The pattern: metros with older housing stock — and the cast-iron or clay lines that come with it — sit at the high end, as do cold-climate cities where lines are buried below a deep frost line.

Start With a Camera Inspection

Before approving any sewer quote, insist on a camera inspection — $100–$500, and many contractors credit it toward the repair. Video evidence tells you whether you need a $700 spot fix or a full replacement, and it's your best protection against paying for more repair than the pipe actually needs.
