The NYC lead service line replacement cost is typically $5,000 to $10,000 when an owner hires a contractor directly, according to DEP's replacement plan. Long runs, deep connections and sidewalk restoration push some jobs higher. It's free only for owners who receive a DEP letter or whose line is found during city water main work.
NYC Repipe & Repair publishes these figures with named sources so every number can be checked before you call anyone, including us.
A lead service line is the pipe between the city water main under the street and your building’s meter. New York allowed lead service lines until 1961 and lead patch repairs until 2009, so many older one- to four-family houses still have one. DEP counts about 121,000 lead or galvanized-requiring-replacement lines citywide, plus about 118,000 of unknown material.
Lead service line replacement prices in NYC
| Route | Typical cost to the owner | Source |
|---|---|---|
| Private replacement, owner hires a contractor | $5,000–$10,000 | NYC DEP replacement plan |
| Brooklyn lead service line, contractor-published | $5,000–$15,000 | A Good Plumber |
| Main water service line, building to street | $8,000–$25,000 | Handyman NYC price guide |
| DEP free program, eligible owners | $0 | NYC DEP program page |
DEP’s own figures show why the private range is the realistic one: the plan puts its contractor cost at about $15,000 a line versus about $10,000 when an owner contracts directly. DEP’s program page says a replacement “can cost more than $8,000”, and the State’s announcement of the program says more than $10,000 (Governor’s office).

What a private replacement includes
A service line job is more than plumbing. Under PC 106.6 of the 2022 NYC Plumbing Code, DEP issues the permits for water supply work and DOT issues the permits for sidewalk and street openings, alongside the plumber’s DOB filing. A complete quote should cover:
- The tap at the main and the new line in Type K copper, the heavy-wall copper used for buried water pipe. Service pipe must meet DEP’s standards (PC 605.3).
- Excavation and the sidewalk or street opening, with the DOT permit and restoration.
- The cellar wall penetration, new main shutoff and the connection at the meter.
- Flushing after the cut-over. DEP gives its own program customers flushing instructions and a filter after replacement, and a private job should include the same step.
- Electrical bonding if the old metal pipe served as the building’s ground.
The lead service line replacement and water line replacement pages show how the work is staged.
What makes one line cost more than another
- Length of run. A house set far back from the curb has more pipe and more excavation.
- Where the main is. A main on the far side of the street means opening more roadway.
- Stoop and areaway. Brownstone lines often run under the stoop and through a vaulted areaway, so access is slow. That’s common across Brooklyn and Park Slope.
- Restoration. Bluestone or decorative paving costs more to put back than plain concrete.
- The pipe indoors. Replacing the service line alone leaves the house plumbing unchanged; galvanized supply inside is often the next job, and it’s cheaper to plan both at once. See cost to replace galvanized pipes and whole house repiping, or price both together with the repipe cost estimator.
The free option, and why it isn’t for everyone
DEP replaces lead or galvanized service lines with copper at no cost, but only for owners who receive a DEP letter or are contacted during DDC water main work. The first phases ran in income-eligible Bronx neighborhoods, then Flushing in Queens, with Soundview and Borough Park next. Only 63% of eligible owners accepted the free replacement, according to DEP’s plan. Everyone else pays privately. Free lead pipe replacement in NYC covers eligibility and what the program leaves out.
Health and timing
DEP’s annual water quality report shows a lead 90th percentile of 10 µg/L at sampled homes, with 16 of 335 over the action level (DEP’s annual water quality report). DEP doses orthophosphate to reduce lead release, which lowers the risk but doesn’t remove the lead. Owners can request a free DEP lead test kit through 311 or online. DEP has no power to order owners to replace their lines, but it supports legislation that would require replacement at sale, during major renovation, or when a free replacement is offered. The DOB filing side is in the repiping permit guide.
Bottom line
Budget $5,000–$10,000 for a private lead service line replacement in NYC, more for long runs or decorative sidewalks, and check first whether a DEP letter makes it free. Ask for a quote that names Type K copper and includes the DEP and DOT permits and restoration. Call (929) 659-6658 for a free on-site estimate with a written, itemized price.
