Sewer line repair, minus the sales pitch
Cracked, collapsed, or full of tree roots — we repair and replace sewer lines across Sydney. If it can be fixed without digging, we'll reline it. If it genuinely needs excavation, we'll show you the camera footage that proves it.
Warning signs
Is your sewer line failing?
- Blockages that keep coming back after clearing
- Sewage smell in the yard, or soggy green patches of lawn
- Slow drains through the whole house, not one fixture
- Gurgling from toilets and floor wastes
- Cracking or sinking in paths above the sewer run
Sydney's pre-1980s homes mostly run earthenware (clay) sewer pipes, and their rubber-ring or mortar joints are an open invitation to tree roots. Once roots are in, every clearing is temporary — the pipe itself needs fixing.
Your options
Reline it, patch it, or replace it
- Trenchless relining — the default. A resin liner cured inside the existing pipe becomes a new structural pipe. No trench, no ruined driveway, lifetime warranty. Handles cracks, root damage and most partial collapses.
- Spot (patch) repair. Damage confined to one short section? A localised patch reline fixes just that section at a fraction of the cost.
- Targeted excavation & replacement. Fully collapsed or badly back-graded pipe can't be relined. We dig the smallest hole that does the job, replace in PVC, and reinstate the surface.
Every recommendation comes with the CCTV footage that justifies it. You'll never be told to dig on our say-so alone.
What it costs
Honest numbers, before we start
Spot repairs & patches
Typically $500–$2,500 per section, depending on depth, diameter and access.
Full-length relining
Commonly $3,000–$15,000 for a house sewer, based on length and diameter. Lifetime warranty.
Excavate & replace
Varies with depth and surface reinstatement — quoted fixed, after the camera confirms it's truly needed.
Ranges are indicative for metro Sydney. Your CCTV inspection converts them into one fixed number.
Straight answers
Sewer repair FAQs
How much does sewer line repair cost in Sydney?
Spot repairs and short relines typically run $500–$2,500 per section. Full-length trenchless relining of a house sewer commonly lands between $3,000 and $15,000 depending on length and diameter. Excavation varies with depth and access. The CCTV inspection turns those ranges into one fixed, written quote before any work starts.
How do I know if my sewer line is broken?
Repeat blockages are the classic tell, along with sewage smells outside, suspiciously lush or soggy lawn patches, house-wide slow drains, gurgling fixtures, and sinking paving over the sewer run. The camera confirms exactly what's going on — cracked, rooted, bellied or collapsed.
Do you always have to dig up the yard?
No — most damage relines without any digging. Excavation is reserved for full collapses, severe misalignment or regrading, and even then it's usually one targeted hole rather than a trench across your garden.
Why do Sydney sewer pipes fail?
Tree roots in the joints of old clay pipes, mostly — standard issue in homes built before the 1980s. Ground movement in clay soils, pipe bellies from poor bedding, corroded cast iron and past building works cover most of the rest.
