Pipe Relining vs. Pipe Replacement: Which One Should You Choose?
Many homeowners discover a small leak that quickly turns into a big plumbing problem. Before long, someone is digging up the yard to repair a broken sewer pipe, creating noise, mess, and high costs.
Today, there is a better way to fix damaged pipes without all the digging. A pipe relining plumber can repair pipes from the inside using modern technology that is clean, fast, and long lasting.
Let’s explore what each method involves, what it costs, and when to choose relining or replacement.
What Is Pipe Relining?
Pipe relining is a modern repair method that fixes existing pipes from the inside. Instead of removing the old pipe, a flexible liner coated with resin is inserted into it. Once the liner hardens, it forms a new pipe within the old one.
This method avoids breaking concrete or digging up gardens and driveways. It keeps the property tidy while restoring the plumbing system.
The Process
- A camera inspection is done to locate the damage.
- The pipe is cleaned with high-pressure water.
- A resin-coated liner is placed inside the damaged pipe.
- The liner is inflated until the resin sets and hardens.
- A final camera inspection confirms that the new lining is smooth and secure.
This process is known as relining of pipes or reline sewer pipe, and it works well for cracks, root damage, and ageing pipes.
When to Choose Pipe Relining
Pipe relining is suitable when:
- Cracks or holes are small, and the pipe structure is still stable.
- The goal is to avoid digging up the yard or driveway.
- There are sewer drain lining problems caused by tree roots.
- Pipes run under tiles, concrete, or landscaped areas.
This method suits both homes and businesses that want a permanent repair with minimal disturbance.
How Much Does Pipe Relining Cost?
The cost of pipe relining depends on several factors, such as pipe size, damage severity, and access.
For those wondering how much to reline a sewer pipe, here is a simple guide:
- Smaller residential jobs often cost between $510 to $1,015 per metre.
- Larger or more complex projects may cost more, especially in commercial settings.
Although the price may seem high at first, pipe relining is often cheaper than a full sewer line replacement once the cost of digging and property repairs is added.
What Is Sewer Line Replacement?
Sewer line replacement involves removing the old pipe completely and installing a new one. This usually means excavation across parts of the property, such as soil, driveways, or floors.
This method is best when:
- The old pipe has collapsed.
- The pipe is too damaged to support a liner.
- The structure has weakened beyond repair.
Replacement is effective but involves more disruption and higher labour costs than relining.

When the pipe is still holding shape, relining is the faster and cleaner way to restore it.
Common Sewer Drain Lining Problems
Even good systems can develop issues if not installed properly. Common problems include:
- Pipes not cleaned well before relining.
- Cheap resin or poor-quality liners.
- Incorrect curing of the resin.
- Tree roots left inside the line before the liner is placed.
Choosing an experienced pipe relining plumber ensures the work is completed correctly from start to finish.
Can Pipe Relining Fix a Broken Sewer Pipe?
In most cases, yes. If the pipe is not completely collapsed, relining can seal cracks, leaks, and weak spots in a broken sewer pipe. The new liner creates a watertight surface that prevents further leaks and improves flow.
How Long Does a Relined Pipe Last?
A well-installed liner can extend the life of a pipe by up to 50 years. It resists corrosion, blocks tree roots, and keeps the plumbing system strong for decades.
Is Pipe Relining Worth It?
For many homes and businesses, yes. Relining saves time, avoids damage to property, and gives a long-lasting repair. It also improves water flow and reduces the risk of future blockages.

FAQs
Can pipe relining be done in any weather?
Pipe relining can be carried out in most weather conditions. Heavy rain may slow down the curing time, but professional plumbers plan around the forecast to ensure a smooth job.
How long does it take before I can use my pipes again after relining?
Most relined pipes can be used within 24 hours. Once the liner is fully cured and checked by camera, your plumbing system is safe to use as normal.
Is pipe relining suitable for old clay pipes?
Yes. Clay pipes are common in older homes, and relining works perfectly for them as long as they are not completely collapsed.
How do I know if my pipes need relining or replacement?
A camera inspection is the best way to tell. It shows whether the pipe is still strong enough for relining or if full replacement is needed.
What materials are used in pipe relining?
High-quality epoxy resin and felt liners are used to form a strong, watertight barrier inside the pipe. These materials are corrosion resistant and last for decades.
