Aging, leaking, or outdated water service lines can cause pressure issues, contamination risks, and costly city intervention. Partial repairs won’t fix structural deterioration. Lady Liberty Contracting Corp provides full water main replacements using durable, NYC-approved copper, installed with proper excavation, bedding, and secure tie-ins to the city main.
Crews remove the failing line entirely, install a new continuous copper service line, complete pressure verification, and restore all affected surfaces to compliant condition.
Older NYC buildings often have aging water mains that pose serious risks: lead contamination, chronic leaks, low pressure, and costly water damage. Replacement with modern materials eliminates these problems permanently and increases property value.
Outdated, unsafe; full replacement required.
Multiple failures show structural deterioration.
Corrosion contaminates water supply.
Undersized or degraded pipe restricts flow.
Severely corroded and unstable material.
Temporary fixes no longer hold.
Additional fixtures require increased capacity.
City connection needs a new or upsized tap.
Continuous, NYC-approved pipe for long-term reliability.
From building foundation to city connection.
Minimized impact with precise trenching.
All required agency filings handled.
Sized to meet building demand and code.
Sized to meet building demand and code.
Stability and flow verified before closure.
Sidewalk, asphalt, and soil restored.
Replacement starts with determining the existing pipe route, size, depth, and material. Crews assess fixture load requirements to select correct copper diameter. Route planning ensures safe trenching and avoids underground utility conflicts. This step confirms the full scope prior to excavation.
NYC DEP permits are required for replacing water service lines. Any street or sidewalk opening requires DOT approval. Utility mark-outs (gas, electric, telecom, fiber) ensure excavation safety. All inspections and agency coordination are managed to prevent administrative delays.
Controlled trenching exposes the entire failing service line. Old lead, galvanized steel, or deteriorated copper is removed completely to eliminate weak points. Excavation depth is stabilized using trench shoring when required.
A continuous Type K copper pipe is installed from the building foundation to the curb valve or tap connection. Pipe bedding is placed to protect against ground movement. All fittings, clamps, and joints follow DEP specifications.
The new copper pipe is connected at both ends and pressure-tested to ensure leak-free performance. Internal building fixtures are checked for stabilized pressure and improved flow.
Trench is compacted in structured layers to prevent settlement. Sidewalk slabs, asphalt, topsoil, or pavers are restored to compliant condition. Final inspections ensure city requirements are met.
