NYC demolition cannot begin until all existing utility connections are fully terminated. This includes cutting, capping, and permanently disabling both the water service line and the sewer at city-approved locations.
Lady Liberty Contracting Corp performs DEP-approved termination, controlled excavation, and full restoration so demolition permits can move forward without delay.
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.
Old service lines must be cut and sealed to avoid uncontrolled flooding.
Uncapped sewers can release wastewater into the demolition site.
