Lady Liberty Contracting Corp provides full-service sitework for residential and select commercial projects across NYC. From excavation and grading to utility preparation, we ensure every site is ready for construction with precision, safety, and efficiency.
With experience going back to 1991, we understand the importance of properly executed sitework. Our team handles excavation, soil compaction, trenching, grading, and drainage preparation to create a solid, safe foundation for any project.
Each task is performed with attention to NYC building codes and safety regulations, ensuring your project starts off on the right foot.
We carefully excavate sites to precise depths and refill areas as needed, creating a stable foundation for construction projects.
Our team digs accurate trenches for water, sewer, and electrical lines, ensuring proper installation and compliance with NYC standards.
We level and grade land to provide smooth, even surfaces, essential for building stability and proper drainage.
We compact soil to increase its density and strength, creating a reliable base for asphalt, concrete, or other surfaces.
We design and prepare drainage solutions to prevent water accumulation, protecting roads, driveways, and other paved surfaces.
We construct retaining walls and implement erosion control measures to stabilize slopes and protect the site from soil movement and water damage.
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.
