Sewer Blockage in Illawarra
Emergency sewer blockage clearing across Wollongong, Kiama, Shellharbour and the greater Illawarra region. Blocked sewers, sewage overflow, tree root intrusion, toilet backups and sewer pipe clearing by licensed plumbers — available 24/7.
A sewer blockage is a complete or partial obstruction in the sewer pipe that carries wastewater from a property to the council sewer main, causing sewage to back up through drains, toilets or the overflow relief gully. In Illawarra, clearing a sewer blockage costs $200-$600 for most residential jobs. An electric eel clears basic blockages for $200-$350, while high-pressure jetting ($300-$500) is more effective for grease, silt and tree root intrusion. CCTV sewer inspection ($200-$350) identifies the exact cause and pipe condition. Tree root intrusion is the leading cause of sewer blockages in Illawarra — roots from figs, willows and camphor laurels enter through clay pipe joints seeking moisture and grow until they completely obstruct flow. Other common causes include flushing non-degradable items (wet wipes, sanitary products), grease accumulation, collapsed or bellied pipe sections, and ground movement displacing pipe joints. A sewer blockage is a health hazard requiring urgent attention, as raw sewage contains E. coli, salmonella, hepatitis A and other pathogens.
Sewer Blockage Services
Emergency Sewer Clearing
Rapid response to active sewer blockages and overflows. We clear the blockage first to stop sewage backup, then investigate the underlying cause.
Electric Eel Clearing
Heavy-duty rotating cable with cutting head breaks through soft blockages — paper, grease and minor root intrusion. Fast and cost-effective for standard blockages.
High-Pressure Jetting
Water pressure up to 5,000 PSI scours the full pipe diameter. The most effective method for grease, heavy root masses and silt accumulation.
CCTV Sewer Inspection
Camera inspection reveals the exact cause of blockage — roots, damage, foreign objects or pipe failure. Essential for diagnosing recurring blockages.
Tree Root Removal
Mechanical cutting and jetting removes invasive tree roots from sewer pipes. We identify entry points and recommend permanent solutions like relining.
Preventive Maintenance
Scheduled sewer cleaning prevents blockages before they cause overflow. Recommended every 12-18 months for properties with trees near sewer lines.

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.
