Sewer Repair in Illawarra
Professional sewer pipe repair across Wollongong, Kiama, Shellharbour and the greater Illawarra region. Collapsed sewers, cracked pipes, tree root damage and joint failures repaired using no-dig relining and traditional excavation methods.
Sewer repair is a plumbing service that restores damaged or failed sewer pipes — the underground pipes carrying wastewater from a property to the council sewer main. In Illawarra, sewer repair costs range from $500 for a localised spot repair to $8,000+ for full line replacement. The two primary methods are pipe relining ($2,000-$6,000), a no-dig technique that inserts a resin-cured fibreglass liner inside the existing pipe creating a seamless new pipe with a 50+ year lifespan, and traditional excavation ($3,000-$8,000+), which involves digging up and replacing the damaged section. Common causes of sewer damage in Illawarra include tree root intrusion through clay pipe joints, ground movement cracking rigid pipes, corrosion of older cast iron sections, and pipe collapse from age. A CCTV sewer inspection ($200-$350) is essential to diagnose the damage type, location and severity before recommending the most cost-effective repair method. We also specialise in sewer pipe relining for strata and body corporate buildings across the Illawarra, where minimal disruption to common areas matters most.
Sewer Repair Services
From no-dig relining to full excavation, we select the most effective and economical repair method for your situation.
Pipe Relining (No-Dig)
A resin-saturated liner is inserted into the damaged pipe and cured in place, creating a seamless new pipe inside the old one. No excavation required — preserves driveways, gardens and landscaping. Lasts 50+ years.
Sewer Excavation & Replacement
When relining isn't suitable, we excavate and replace the damaged section with new PVC pipe. Required for severely collapsed pipes, bellied sections and misaligned connections.
CCTV Sewer Inspection
High-definition cameras inspect the full length of your sewer pipe, identifying cracks, root intrusion, joint displacement, bellies and collapses. Footage and written reports provided.
Emergency Sewer Repair
Collapsed sewers and major breaks causing overflow need immediate attention. Our emergency service provides rapid assessment and temporary containment while permanent repairs are planned.
Tree Root Damage Repair
Tree roots enter through pipe joints and grow inside, cracking and displacing the pipe. We remove roots, repair the damage and seal entry points permanently through relining or joint repair.
Sewer Connection Repair
Repair damaged junction connections where your property sewer meets the council main, or where branch lines connect. Includes re-establishing proper falls and sealing joints.

What drain and sewer work costs
Published 2026 ranges for NSW. Where roots are involved and need cutting before jetting, expect the higher band.
| Job | Typical range | What affects it |
|---|---|---|
| Blocked sink or basin | $150 – $300 | Usually cleared on the first visit. |
| Blocked toilet | $180 – $350 | Higher if the pan has to come up. |
| Blocked main sewer line | $300 – $800+ | Depends on access, depth and cause. |
| Jet rodding (hydro jetting) | $250 – $800 | High-pressure water. Clears grease, silt and fine roots. |
| Root cutting plus jet rodding | $400 – $1,500 | Mechanical cutter first, then jetting to flush the debris. |
| CCTV drain camera inspection | $250 – $550 | Often credited toward the repair if you proceed. Sources range $150–$750. |
These are typical price ranges for the Illawarra and NSW, drawn from published 2026 industry pricing data — not a quote, and not our fixed prices. What your job actually costs depends on access, the age and condition of the plumbing, parts, and whether it is after hours. We give you a fixed price before we start work, so you are never guessing.
