Pipe relining and no-dig drain repair, Sydney
Pipe relining repairs cracked, collapsed or tree-root damaged stormwater, sewer and drainage pipes without digging up the yard, driveway or floor above them. A resin-saturated liner is inserted into the existing pipe and cured in place, forming a new pipe within the old one.
It's often faster and cheaper than full pipe replacement because it avoids the cost of excavation and reinstating whatever sits above the pipe: landscaping, paving or a slab.
Typical job value: $3,000 – $15,000

What's involved
CCTV inspection
A camera is run through the pipe to locate and assess the damage before quoting.
Cleaning
The pipe is cleared of roots, debris and buildup with high-pressure water jetting so the liner can bond properly.
Relining
A resin-saturated liner is inserted and inflated against the pipe walls, then cured (often with UV light or hot water), to form a new pipe surface.
Final CCTV check
A follow-up camera inspection confirms the reline is sound and the pipe is clear.
What affects the price
- Length and diameter of pipe being relined
- Extent of damage: a single crack vs multiple collapsed sections, which may still need excavation
- Access points available
- Whether a CCTV drain inspection is needed first to scope the damage
Licensing and permits
Pipe relining and drainage work in NSW should be carried out by a licensed plumber or drainer holding the relevant NSW Fair Trading licence, since it involves working on sewer and stormwater infrastructure that's subject to plumbing regulations.
Common questions
Is pipe relining as strong as a new pipe?
Yes, cured liners are typically rated for a similar lifespan to a new pipe, often 50-plus years, and resist root intrusion better than the original pipe did.
Can any damaged pipe be relined, or does it need replacing?
Most cracks, root damage and offset joints can be relined. Fully collapsed sections or pipes with significant grade issues sometimes still need traditional excavation and replacement for that section; a CCTV inspection determines which applies.
How long does pipe relining take?
A straightforward residential reline is often completed within a day, including the CCTV inspection and jetting beforehand, though larger or more damaged sections can take longer.
Will relining fix tree root problems permanently?
Relining removes the cracks and joints roots were entering through, which significantly reduces future root intrusion, though nearby tree roots can still be a longer-term consideration depending on species and proximity.
Do I need council approval for pipe relining?
Generally no for like-for-like repair of an existing private drainage pipe, since no excavation or new pipe placement is involved, but check with your plumber if the work extends to council-owned stormwater infrastructure.
How much does pipe relining cost compared to digging up the pipe?
It varies by job, but relining is often cheaper once you account for the cost of excavating and reinstating paving, landscaping or a slab that a dig-up repair would require.
