Frequently asked questions
Below are answers to questions our customers frequently ask about our water main and sewer services, processes, and expertise.
Do you offer lead service line replacement?
Yes, we specialize in lead service line replacement. Replacing lead water lines is essential for protecting your family’s health, and we’re experienced in safely and efficiently upgrading these outdated systems to modern, safe alternatives.
What is involved in a water main replacement?
A complete water main replacement typically involves excavation to access the existing line, removal of the old pipe, installation of new piping, connection to the city water supply, testing for proper function, and restoration of the excavated area. We handle all necessary permits and inspections as part of our service.
What materials do you use for water main replacement?
We use high-quality, durable materials that comply with all NYC DEP regulations. Depending on your specific situation, we may use copper or other approved materials that provide long-lasting performance and comply with current health standards.
How do I know if my water main needs to be replaced rather than repaired?
Water mains typically need replacement if they’re severely corroded, repeatedly developing leaks, made of outdated materials (like lead or galvanized steel), or if the damage is too extensive for repair. Our technicians can assess your situation and recommend the most cost-effective solution.
