Sewer Line Replacement Cost: Per-Foot Rates by Material and Method

Sewer line replacement costs $50 to $250 per linear foot, or $2,000 to $10,000 for a typical 40-foot line.² Angi’s project average is $3,319; HomeGuide’s national average is $6,000.¹² Repairs run $150 to $3,800 depending on method.² Prices below are national averages* for 2026.

*National averages, not local quotes. Your price depends on pipe length, material, depth, access, and local labor rates. Main sewer line work requires a licensed plumber and permits.

Quick math: both references quote $50 to $250 per linear foot installed, so a 40-foot replacement lands at $2,000 to $10,000, our arithmetic.¹² Their averages disagree — Angi $3,319 (about $83 per foot on 40 feet, our arithmetic) versus HomeGuide $6,000 ($150 per foot) — because Angi’s dataset blends partial and complete jobs while HomeGuide’s reflects full replacements.¹² For a full 40-foot trench-and-replace, plan on $4,000 to $8,000, our judgment from the overlap.

Cost by length

Length replaced	Total cost ($50 – $250 per ft)
10 linear feet	$500 – $2,500
20 linear feet	$1,000 – $5,000
40 linear feet (typical full line)	$2,000 – $10,000
60 linear feet	$3,000 – $15,000
80 linear feet	$4,000 – $20,000

Each row is the per-foot band times the length, our arithmetic matching HomeGuide’s table.² Most full replacements run about 40 feet — the distance from house to street hookup — while partial replacements typically cover 1 to 15 feet.²

Cost by pipe material

Pipe material (4-inch)	Materials per ft, HomeGuide	Angi average per ft
PVC	$3 – $8	$4.50
ABS	$3 – $11	$6
Copper	$30 – $80	$85
Cast iron	$20 – $75	$50
PEX	$2 – $10	—

Materials are a small slice of the bill — even 40 feet of copper at $80 per foot is $3,200 in pipe, our arithmetic, against labor and excavation that dominate a $6,000 job.² PVC and ABS are the common choices; copper and cast iron cost more but last longer, and repairing them can double plastic-pipe repair prices (HomeAdvisor).³

Cost by method: repair, trenchless, replace

Method	Cost	When it fits
Snaking	$150 – $500 (HomeGuide)	Minor clogs, older pipes
Hydro jetting	$250 – $800 (HomeGuide)	Major clogs, tree roots
CIPP lining	$90 – $250 per ft	Cracked but intact pipe, no digging
Spin-casting	$80 – $250 per ft	Resin coating without a liner
Pipe bursting	$60 – $200 per ft	Full replacement without open trench
Complete replacement	$60 – $250 per ft (Angi)	Collapsed or failed line

Trenchless methods (CIPP, spin-casting, bursting) avoid excavation but cost as much per foot as open-trench replacement — the savings come from skipping yard, driveway, and sidewalk restoration, not from the pipe work itself.² Angi’s partial replacement rate is about $50 per foot, the cheapest line-level fix.¹

Inspection, permits, and extras

A sewer camera inspection costs $125 to $500 (HomeGuide) or $100 to $500 (Angi) and should precede any quote.¹² Plumbing permits run $30 to $500.² Access drives extras: concrete removal adds $3 to $8 per square foot, a backflow preventer $150 to $1,200, and a new cleanout $500 to $2,000 (HomeGuide).² Landscapers, driveway repair, and sodding add indirect restoration costs on trenched jobs (HomeAdvisor).³ Most plumbers charge $75 to $150 per hour.²

Worked examples

Example 1 — standard 40-foot full replacement, PVC. 40 ft × $50 to $250 = $2,000 to $10,000 installed, our arithmetic.² Mid-band at $150 per foot (Angi’s average rate) = $6,000, matching HomeGuide’s national average.¹²

Example 2 — 25-foot partial replacement. 25 ft × $50 = $1,250, our arithmetic at Angi’s partial rate — plus $125 to $500 camera inspection and $30 to $500 permit, call it $1,400 to $2,250 all-in.¹²

Example 3 — labor sense-check. At $75 to $150 per hour, a two-day job (16 hours, one plumber) runs $1,200 to $2,400 in labor, our arithmetic — consistent with labor dominating a $2,000 to $6,000 replacement.²

FAQ

Repair or replace? Clogs and small root intrusions can be snaked ($150 to $500) or hydro jetted ($250 to $800); broken, cracked, or collapsed lines need partial replacement or lining (HomeGuide).²

Is trenchless cheaper? Per foot, no — CIPP and bursting run $60 to $250 per foot like open trench. The savings are in skipped restoration: no driveway, sod, or sidewalk rebuild (HomeGuide).²

Why do the averages disagree ($3,319 vs $6,000)? Angi’s blends partial and complete jobs; HomeGuide’s reflects full replacements. Angi and HomeAdvisor publish the same dataset, so count them as one reference.¹²³

What pipe material is best value? PVC at $3 to $8 per foot materials (HomeGuide) — corrosion-proof and cheap. Copper and cast iron last longer but cost up to ten times more in materials.²

Who pays — me or the city? Homeowners usually cover the full line from house to street hookup; townhome and condo owners may have HOA coverage (HomeGuide).²

DIY shopping: a handheld drain auger handles minor fixture clogs before they reach the main line (plain link, no affiliate relationship). Main-line work stays with the pros.
