If your house sewer is old, badly deteriorated, or failing in several locations, small repairs will not hold for long. Sewer line replacement provides a clean, reliable connection to the city sewer and removes a major risk from your property.
Frequent sewer backups despite repairs
Sewer line over 50+ years old (clay or cast iron)
Collapsed, crushed, or severely cracked pipe
Tree root invasion throughout entire line
Repeated repair costs exceeding replacement value
Technicians review all available sewer camera footage to map defects, measure distances, confirm depth, and identify city connection points. The replacement route is planned to maintain safe excavation paths and proper grade from building exit to city tie-in.
Full replacement requires DOT street/sidewalk opening permits and DEP sewer permits. Utility mark-outs (gas, electric, telecom, fiber) identify underground conflicts. Scheduling ensures compliance and safe excavation operations.
Controlled trenching exposes the full length of the sewer. Old clay, cast iron, or deteriorated pipe is removed completely. Trench shoring is installed where depth or soil conditions require additional support.
New sewer pipe is placed with correct bedding and slope to ensure unimpeded flow. Sections are joined using mechanical couplings rated for underground sewer systems. Cleanouts and a new house trap are installed when required by NYC code.
The new sewer connects to the city line or house trap with code-compliant fittings. Water tests confirm proper flow and alignment. Required DEP/DOB inspections are completed before closure.
Trench is backfilled in compacted layers to prevent settlement. Sidewalk slabs, asphalt, pavers, gravel beds, or landscaped areas are restored to safe, compliant condition. Final checks ensure proper finish and site cleanup.
There will be excavation along the route of the line. We keep trenches as narrow as practical and restore surfaces once work and inspections are complete.
Yes. Combining sewer and water work often saves time and reduces overall disruption and cost.
If you are tired of constant backups and short-term fixes, it may be time for a full sewer replacement designed to last.
