Sewer Line Repair - Trenchless Relining, 50-Year Warranty

Sewer line failures in Sydney almost always trace back to three causes: tree roots forcing into 1950s-1970s vitrified clay (VC) earthenware joints, ground movement cracking pipes in reactive Wianamatta shale soils, and corroded cast-iron stacks from inner-city terraces. Tradetek Solutions diagnoses and repairs all three across Sydney metro, the Central Coast and Newcastle.

Every job starts with a colour CCTV inspection and sonde location so we mark the exact fault on the surface before we recommend a repair method. We provide you with the camera footage, depth readings and a written report - not a verbal 'trust us, it's collapsed' upsell. That report is also what Sydney Water accepts for boundary trap and overflow relief gully (ORG) approval.

Trenchless cured-in-place pipe (CIPP) relining is our default for buried sewers under driveways, slabs and established gardens. Costs start at $450 per metre fully installed with a 50-year structural warranty. A typical 8-metre relined section runs $3,600-$5,200 total - dramatically cheaper than the $8,000-$15,000 excavation cost once you factor in driveway and landscaping reinstatement.

When excavation is genuinely the right call - shallow shifts, full collapses, or new junction installations - we run full dial-before-you-dig clearances, use vacuum excavation around live services, and reinstate to council standards. Excavated repairs start at $4,800 for a 1.5m-deep junction and scale with depth, surface type and Sydney Water boundary connections.

All work is performed by licensed Tradetek plumbers (NSW Fair Trading licence number on every quote), compliant with AS/NZS 3500.2 sanitary plumbing and Sydney Water's Water Services Coordinator requirements. We service the full Sydney basin from the Sutherland Shire through to the Northern Beaches, Hills District, Inner West and out to Penrith - same-day CCTV in most areas.
