Sewer line failures create immediate operational hazards. Structural cracks, root intrusion, pipe offsets, and partial collapses lead to backups, drainage slowdowns, wastewater exposure, and potential property damage.
Lady Liberty Contracting Corp performs precise, localized sewer line repair that isolates the defect, replaces only the compromised section, restores flow integrity, and meets all NYC code requirements.
Crews expose the defective pipe through controlled excavation, remove damaged sections, install new code-approved materials, and restore all disturbed surfaces to safe condition.
Repeated wastewater backup at lowest fixtures.
Multiple fixtures draining slowly at once.
Toilets or sinks making gurgling sounds.
Odors coming from basement or yard areas.
Wet or sunken soil along sewer path.
Wastewater rising at cleanout during use.
Roots penetrating old clay or cast iron pipe.
Small structural failures limited to one section.
Locates defect when access is available.
Dig only at the damaged section.
Replace only the failed pipe length.
Use of extra-heavy cast iron or NYC-approved PVC.
Re-establish proper grade for uninterrupted flow.
Secure installation for long-term stability.
Prevents future settlement and surface issues.
Restoration of sidewalk, asphalt, stone, or soil.
Where access allows, sewer camera equipment is inserted into the line to locate defects, measure distance, and identify cause (roots, cracks, corrosion, offset, partial collapse). If camera access is limited, crews diagnose based on fixture behavior, cleanout conditions, and site data. This determines whether repair is viable or full replacement is required.
If excavation extends into the curb, sidewalk, or street, DOT and DEP permits are required. Utility mark-outs (gas, electric, telecom) ensure safe trenching conditions. Work is planned to minimize disruption and protect adjacent infrastructure.
Excavation starts at the exact defect location. Soil, asphalt, or concrete is removed to expose the damaged pipe. Shoring is installed when trench depth requires structural support. The defective length is fully assessed before removal.
The compromised segment is cut out. New, code-compliant materials—extra-heavy cast iron or approved PVC (where allowed)—are installed. Connections are secured, slopes re-established, and joints aligned to prevent future failures.
Water is run through the line to confirm stable drainage. Where possible, a post-repair camera check verifies slope and alignment. All corrections are completed before closure.
The trench is compacted in controlled layers to prevent settlement. Sidewalk flags, asphalt patches, stone surfaces, and soil are restored to safe and usable condition following NYC requirements.

Corrects grade and alignment for consistent flow
Removes roots, cracks, and localized structural defects
Reduces future emergency risk and system stress
Complies with NYC DEP, DOT, and DOB standards
Minimizes excavation footprint and property disturbance
When access exists, yes. Some older properties lack usable entry points.
Yes. Sewer repair operates year-round.
A localized repair in an otherwise stable line can last decades.
When multiple cracks, sags, or collapses appear along long sections.
Only if the defect lies near the curb or city connection.
Prevent backups, structural soil issues, and wastewater exposure. Restore safe drainage through a targeted, code-compliant sewer repair.
What we can show you in writing before any work starts.
Yes. Lady Liberty Contracting Corp is fully licensed, bonded and insured for water main and sewer work throughout New York City. Certificates of insurance and licence details are available on request before any work begins.
The work is carried out under a New York City Licensed Master Plumber on our own staff, not subcontracted to another firm. That matters on permitted work, because the DEP and DOT filings are pulled under the licence of the plumber responsible for the job.
Yes. Every installation and repair carries a 10-year workmanship guarantee. If an issue arises that relates to our work, we come back and put it right.
We handle them. Permit filing, inspections and sign-off are managed in-house as part of the job, including street-opening permits and the restoration that follows.
Yes. Water main and sewer replacements are large, unplanned expenses, and payment options are available. See financing and flexible payment options.
We work on the water and sewer lines that connect a property to the city main: service line repairs and replacements, sewer laterals, excavation, DEP and DOT permitted work, and the street and sidewalk restoration afterwards. That covers residential, commercial and municipal properties across all five boroughs. We do not take on interior plumbing — in-house leaks, fixtures, heating or boiler work.
