Pipe problems can cause major headaches for homeowners and businesses. Traditionally, fixing damaged pipes meant digging up the ground, removing old pipes, and replacing them entirely — a process that can be expensive, time-consuming, and disruptive.
Fortunately, pipe relining has become a smarter and more cost-effective alternative. But how much does it actually cost in Sydney? Let’s break it down clearly so you can plan your next plumbing repair with confidence.
What Is Pipe Relining?
Pipe relining is a modern plumbing solution that repairs pipes from the inside without the need for excavation. A resin-soaked liner is inserted into the damaged pipe, then cured to form a strong, seamless “pipe within a pipe.”
This technique is effective for repairing leaks, cracks, root intrusion, and corrosion. It works on a range of materials including clay, PVC, and cast iron. Because it requires minimal digging, it’s much faster and more cost-efficient than traditional replacement methods.
Typical Cost of Pipe Relining in Sydney
While prices vary depending on the job, the average pipe relining cost in Sydney typically ranges from $400 to $800 per metre. More complex jobs, such as those involving larger pipes or difficult access points, can be higher.
Here’s a general guide to help you understand how pricing is usually structured:
- Average Cost: $400 – $800 per metre
- Typical Conditions: Suitable for straightforward access areas with standard pipe diameters.
- Average Cost: $800 – $1,000 per metre
- Typical Conditions: Required for tight spaces, complex layouts, or larger pipe sizes.
- Average Cost: $2,000 – $4,000 (total)
- Typical Conditions: Used for small, localised repairs on a single damaged pipe section.
Keep in mind that this is just a guide. The final cost will depend on your property’s specific plumbing layout and the condition of your pipes.
Key Factors That Influence the Cost
Several factors can affect the final price of a pipe relining project. Understanding these can help you make informed decisions and avoid unexpected costs.
- Length of the pipe
Longer pipe sections usually cost more overall, but the price per metre may decrease as the setup cost is spread out. - Pipe diameter
Larger pipes require more materials and labour, which increases the cost. - Access to the pipes
If pipes are located under concrete, driveways, or tight spaces, additional preparation may be needed. - Pipe condition
Pipes with extensive damage, blockages, or tree root intrusion often need more cleaning and prep work. - Number of bends and junctions
Straight pipe runs are easier and cheaper to reline, while multiple junctions add complexity. - Type of relining method used
Different relining systems and materials come with varying costs and warranties. - Fixed setup fees
Some projects involve additional charges for site setup, equipment mobilisation, or council permits.

Why Pipe Relining Can Save You Money
Even though the upfront cost might seem high, pipe relining is often more affordable in the long run compared to digging and replacing pipes. Here’s why:
- Minimal excavation – No need to tear up your garden, driveway, or flooring.
- Faster turnaround – Many jobs can be completed in a single day.
- Less restoration work – No extra cost for reinstating landscaping or concrete.
- Long-lasting results – Properly relined pipes can last for decades.
- Prevents future issues – The seamless liner reduces the risk of future blockages and root intrusion.
Tips for Getting a Fair Quote
When choosing a plumbing company for pipe relining, here are a few things to keep in mind:
- Request a detailed written quote with a clear cost breakdown.
- Make sure the plumber conducts a CCTV pipe inspection before quoting.
- Ask about warranty and product lifespan.
- Check the company’s licenses, experience, and reviews.
- Understand any minimum call-out or setup fees.
- Be cautious of unusually cheap quotes that may not include everything.
