Sewer Pipe Repairs
Cracked, root-invaded or collapsed sewer pipes: diagnosed on camera, located to the centimetre, and repaired by targeted excavation or trenchless relining.
How are broken sewer pipes repaired?
Two ways: targeted excavation (dig down to the damaged section and replace it) or no-dig pipe relining (line the pipe from the inside, sealing cracks and root entries without excavation). The right choice depends on the damage. A CCTV camera inspection shows which, and locating equipment pinpoints exactly where to work, so you're quoted on facts.
Diagnosis First
Sewer repairs built on diagnosis, not digging
Nothing about a broken sewer is visible from the surface, which is why sewer repair quotes vary so wildly. Ready Plumbing does it in the right order: CCTV camera inspection first to see the damage, whether breaks, cracks, root intrusion or backfall, then locating equipment to establish exactly where the fault is and how deep the pipe runs. You see the footage, you see the spot marked on the ground, and the quote is for fixing a known problem in a known place.
Know The Signs
The signs your sewer line is failing
- Blockages that keep coming back: cleared roots regrow through the same entry point within months
- Sewer smell in the yard, or damp patches that don’t dry out
- Suspiciously lush grass along one line of the lawn (the sewer is feeding it)
- Gurgling fixtures and slow drains throughout the house
- Overflow at the boundary trap or overflow relief gully: the system’s designed warning signals
One blockage is bad luck. A pattern is a broken pipe, and clearing it repeatedly costs more than fixing it once.
Two Ways To Fix It
Two ways to fix a broken sewer
- No-dig pipe relining: For cracked, root-invaded but structurally intact pipes, relining is usually the winner: a resin liner is installed through the existing pipe and cured in place, sealing cracks and root entries with a smooth new pipe inside the old one. No trench, no destroyed garden, and backed by a lifetime labour guarantee.
- Targeted excavation: Fully collapsed sections, severe backfall or crushed pipes need physical replacement. Because the fault is located precisely, this means one properly sized hole in the right place, not an exploratory trench across the yard. We repair the section, verify the whole line on camera, and reinstate the site.

FAQ
Sewer Pipe Repairs: your questions answered
Plumbing problems can be extremely frustrating. Our licensed Sydney plumbers are here to provide fast, reliable answers and solutions.
How do I know if my sewer pipe is broken?
Recurring blockages are the classic sign: roots keep coming back through the same crack. Others: sewer smells in the yard, unusually green patches of lawn over the line, damp or sunken ground, gurgling drains, and overflow at the boundary trap or gully. A camera inspection confirms it either way.
Do you have to dig up my yard?
Often not. No-dig pipe relining repairs cracked and root-damaged pipes from the inside, with no trench through the garden. Where a section is fully collapsed or badly back-falling, targeted excavation is the honest fix, and precise locating means we dig one small hole in the right place, not a trench along the whole line.
Who is responsible for sewer pipe repairs: me or Sydney Water?
As a rule, the pipes on your property up to the utility's connection point are the owner's responsibility; the mains beyond it are Sydney Water's. Our camera and locator establish exactly where the problem sits, so you're not paying to fix something that isn't yours.
What causes sewer pipes to fail?
Age and material are the big ones: older earthenware pipes crack at the joints, and tree roots exploit every gap. Add ground movement, previous poor repairs, and backfall that lets waste sit in the line, and eventually the pipe fails.
