Sewer Repair in Manhattan

Sewer Repair in Manhattan, From the Building to the City Sewer

Most Manhattan sewer work happens under a building that is somebody’s home or business all day, on a street that never empties. We camera the line, find the failure, and plan the repair around the building, the DOT permit and the traffic, then fix the section or replace the house sewer to the city sewer.

Crowded Ground

Manhattan streets are crowded with utilities, so the mark-out matters more and a lot of the digging near other lines is done by hand. Many buildings have sidewalk vaults, which change where the excavation can go.

DOT limits street work on busy streets during rush hours and around the holidays, and the permit sets the hours. The pipe is the same story as everywhere: clay tile and cast iron, cracked joints, and roots from street trees on residential blocks in Harlem, the Upper West Side and the Village.

Signs Your Sewer Line Is Failing

  • Backups at the lowest drain in the building, usually in the basement
  • Slow drains on more than one fixture at once
  • Gurgling from toilets or sinks
  • A sewer smell in the basement or the yard
  • A wet or sunken strip of ground along the line
  • Water rising at the cleanout

One of these is a warning. Two or more, together, usually mean the line itself.

Camera First, Then the Price

We find out what is wrong before anyone digs. A sewer camera inspection is a paid service: you get the video and a written report, and the repair is priced from what the camera found. Anyone who quotes a sewer repair over the phone is guessing, and you pay for the guess later.

Repair or Replace?

A spot repair is usually enough when

  • The camera finds one break or one failed joint
  • The rest of the pipe is sound, with no sags or heavy roots
  • It is the first failure on that line

Full replacement is the better call when

  • Backups keep coming back after repairs
  • The camera shows several breaks, bellies or roots at many joints
  • The line is old clay tile or badly corroded cast iron
  • You are adding units or fixtures the old line cannot carry

Repairs and replacements are done in extra-heavy cast iron or NYC-approved PVC, with a new house trap and cleanout where they are needed. Where the line allows it, trenchless repair leaves less of the sidewalk or yard open. More on NYC sewer line repair and NYC sewer line replacement.

About Sewer Backups

A snake clears a blockage. It does not fix a broken pipe. If a backup clears and never comes back, you probably did not need us. If it keeps coming back, the line is usually cracked, sagging or full of roots, and the camera will show which.

Whose Line Is It?

In New York City the house sewer belongs to the property owner all the way to the connection at the city sewer, including the part under the sidewalk and the street. DEP maintains the city sewer itself, and when it finds a defect on the owner's side it can send a sewer defect notice. We handle those too: see DEP notices and compliance.

How a Manhattan Sewer Job Runs

  1. Camera the line. The footage shows the failure and its distance from the house.
  2. Permits and mark-out. We file with DEP, pull the DOT street-opening permit for work under the sidewalk or roadway, and call in the utility mark-out.
  3. Dig only what is needed. On a busy street, the DOT permit sets our working hours, and the schedule is built around them.
  4. Repair or replace. NYC-approved materials, under the licence of Master Plumber #2389.
  5. Test and inspect. A flow test and the city inspection before anything is backfilled.
  6. Restore. Backfill, then the sidewalk, curb, street or yard put back.

The digging is the quick part. The permits set the calendar.

Manhattan Sewer Repair FAQs

Who is responsible for the sewer line from a Manhattan building to the street?

The property owner. In New York City the house sewer is private from the building to the connection at the city sewer, including the part under the sidewalk and the street. DEP maintains the city sewer itself.

Do you charge for a sewer camera inspection?

Yes. It is a paid inspection, and you keep the video and a written report. If the line needs work, the repair is priced from that footage.

How do I know if it is my sewer line or the city sewer?

If several buildings on the block back up at the same time, the city sewer may be the problem: report it to 311. If it is only your building, it is usually your line, and the camera will show where.

My street was just repaved. Can you still open it?

Sometimes. The city treats recently resurfaced streets as protected: opening one needs DOT approval, comes with stricter restoration rules, and some work has to wait. We check a street's status before we quote, so you know before anything is scheduled.

Our building has a sidewalk vault. Can you still reach the sewer?

Usually, yes. The vault changes where the excavation can go, so we look at it before we plan the work and the quote.

Can you work around a co-op or condo board's schedule?

Yes. We work with boards and managing agents on access, notice to residents and working hours, within what the DOT permit allows.
