Sewer Replacement Process
Sewer Camera Inspection
We insert a high-definition camera into your sewer line to identify the exact location, type, and severity of the problem — whether it's a crack, collapse, root intrusion, or bellied pipe.
DEP & DOT Permit Filing
Our team files all required permits with NYC DEP for sewer work and DOT for any street opening. We handle the entire bureaucratic process so you don't have to.
Controlled Excavation
Using precision excavation equipment, we carefully dig to expose the damaged sewer line while protecting surrounding utilities, foundations, and landscaping.
Old Pipe Removal & New Installation
We remove the damaged pipe and install a new extra-heavy cast iron or PVC sewer line, ensuring proper pitch and connections to both your building and the city sewer main.
DEP Final Inspection
A NYC DEP inspector examines the new installation to verify it meets all building codes and regulations. We coordinate the inspection and address any requirements on the spot.
Complete Site Restoration
We backfill with approved materials, restore concrete, asphalt, or landscaping to pre-work condition, and perform a final cleanup of the entire work area.
