Step 1 of 3

What type of pipe is it?

This affects the liner size, resin volume and setup involved.

How much pipe needs relining?

Rough estimate is fine — length is confirmed precisely by CCTV.

Not sure of the length? Choose the range that feels closest — the estimate adjusts as you go.

Any junctions or branch connections?

A junction is where another pipe branches off from the section being relined. Each one needs to be reinstated after curing.

Transparent pricing

How the price is built — three components

Every pipe relining job has the same three cost components. Understanding them removes the mystery from any quote you receive.

Standard house drain — 100mm
Base fee (setup, CCTV, clean)
Fixed per job
$2,500
Per metre of liner
Liner + resin + labour
$450/m
Per junction reinstated
Robotic cutter, per branch
$750
Larger / shared line — 150mm+
Base fee (setup, CCTV, clean)
Fixed per job
$2,800
Per metre of liner
Larger liner + more resin
$650/m
Per junction reinstated
Robotic cutter, per branch
$950

Total estimate = Base fee + (metres × per-metre rate) + (junctions × per-junction rate)

All prices include GST. This is the same model used by the calculator above. Your final fixed price is confirmed by CCTV scope before work begins.

Real scenarios

What typical Sydney jobs actually cost

These are representative examples using the standard pricing model — they show how base fee, length and junctions combine in practice.

Short repair

Terrace in Newtown

Root intrusion in a 5m section of clay drain beneath a courtyard. Standard 100mm pipe, no junctions in the relined section.

Base fee$2,500
5m × $450$2,250
0 junctions$0
Total$4,750

No excavation. Relined through existing gully trap.

Typical home

House in Mosman

Cracked sewer line, 12 metres from rear of house to boundary. Standard 100mm drain with 2 junctions (laundry and bathroom branches).

Base fee$2,500
12m × $450$5,400
2 junctions × $750$1,500
Total$9,400

Driveway completely untouched. Job completed in one day.

Shared / strata

Strata block in Randwick

Shared sewer main, 20 metres, serving four apartments. Larger 150mm pipe with 3 branch junctions.

Base fee$2,800
20m × $650$13,000
3 junctions × $950$2,850
Total$18,650

Minimal disruption to residents. Written scope for strata committee.

Common question

Why does a short job cost so much per metre?

The base fee applies to every job regardless of length — it covers mobilisation, the CCTV inspection, high-pressure pipe cleaning, root cutting and technician time before the liner ever goes in. On a 2m repair, that base cost represents most of the total. On a 15m run, it becomes a smaller proportion and the effective per-metre cost looks much lower.

This is why any quoted "per metre" rate in isolation is misleading. A company advertising "$450/m relining" could still quote $5,000 for a 5m job once the base fee, cleaning and inspection are included. The calculator on this page builds the estimate properly — base fee first, then metres, then junctions — so you can see exactly where the cost comes from.

Cost factors

What affects the final price beyond the estimate

The calculator gives a solid starting point. These are the on-site factors that can adjust the fixed quote after CCTV inspection.

Pipe condition and damage type

Minor cracking is simpler to prepare than heavy root intrusion, partial collapse or offset joints. Severe damage may require extra cleaning passes or, in rare cases, a short excavation before relining is possible.

In practice: CCTV identifies this precisely — it is reflected in the fixed quote before work begins.

Access to the pipe

Relining through an existing gully trap or inspection shaft is straightforward. Limited access, deep pipes, or situations where an access pit needs to be installed add time and cost.

In practice: If additional access is needed, this is scoped and priced before work starts — not added afterwards.

Pipe diameter

Wider pipes need wider liner, more resin and sometimes a different installation method. The calculator separates 100mm (standard) from 150mm+ (larger/shared) to reflect this. Unusual sizes outside this range are quoted individually.

In practice: Pipe size is confirmed during the CCTV inspection.

Number and complexity of junctions

Each junction within the relined section needs robotic reinstatement after the liner cures. Multiple junctions or tight branch angles add to the post-cure work time.

In practice: All junctions are identified by CCTV and included in the fixed scope.

Curing method and cure time

Most residential relining uses ambient or hot-water curing. UV curing is faster but involves different equipment. The method used affects scheduling more than cost, though it can be relevant for urgent jobs.

In practice: Discussed during the quoting process based on pipe type and urgency.
Cost comparison

Pipe relining vs the alternatives

The right comparison is not just the relining quote — it is the total cost of each option, including what happens to your property.

Most common

Pipe relining

  • ✓One fixed cost — no hidden extras
  • ✓No excavation, no reinstatement cost
  • ✓Completed in 1–2 days (most jobs)
  • ✓50+ year liner design life
  • ✗May not suit severely collapsed pipes
For severe collapse

Excavation and replacement

  • –Pipe replacement cost
  • –Excavation and backfill
  • –Reinstatement: concrete, paving, garden
  • –Potentially multiple trades

  • ✗Costs accumulate — $389–$600+ per clearance
  • ✗Root intrusion returns every 6–18 months
  • –Suitable while damage is being assessed

FAQ

Pipe relining cost — common questions

Answers to what Sydney homeowners ask us most about price.

How much does pipe relining cost in Sydney?
Most pipe relining jobs in Sydney fall between $3,500 and $15,000 depending on how much pipe needs relining, the pipe diameter, access conditions and the number of junctions involved. The calculator on this page gives a realistic estimate based on a standard pricing model. A fixed price is confirmed after CCTV inspection before any work begins.
Why does pipe relining have a setup or base fee?
The base fee covers mobilisation, CCTV inspection to confirm scope, high-pressure pipe cleaning and root clearing, and technician time before the liner goes in. These costs apply to every job regardless of length, which is why even short repairs carry a minimum base cost of around $2,500.
What is a junction and why does it cost extra?
A junction is where another pipe branches off from the main line being relined. After the liner cures, each junction must be reinstated (cut open) using a robotic cutter so drainage continues correctly. Junction reinstatement adds time and labour — typically $750–$950 per junction depending on pipe size.
Why are shorter relining jobs expensive per metre?
The base setup fee is spread across fewer metres on shorter jobs, making the effective per-metre cost appear high. A 2m repair costing $3,400 is not $1,700/m in materials — most of that cost is mobilisation, CCTV and preparation. The per-metre liner component is a smaller part of any short repair.
Is pipe relining cheaper than digging up the pipe?
In most cases where relining is suitable, yes — because excavation requires digging, removing old pipe, installing new pipe and reinstating whatever surface is above it. Relining avoids all reinstatement costs. The total project cost is typically 30–50% lower than excavation for the same pipe run, though this depends on access and conditions.
What is included in the pipe relining price?
A complete job typically includes CCTV inspection to confirm scope, high-pressure cleaning and root clearing, liner material and resin, installation and curing, robotic junction reinstatement where required, and a post-lining camera inspection confirming the repair. Drainr provides a written scope before work begins.
How accurate is the estimate from the calculator?
The calculator gives a useful planning range based on typical Sydney jobs. It is a guide, not a quote. The actual fixed price depends on exact pipe length, diameter, access conditions and pipe condition — all confirmed during the CCTV inspection before any work begins.
