The Truth About Pipe Relining Costs: Is it Worth the Investment?

December 2, 2022by Alex

If you’re dealing with damaged or broken pipes in your home or business, you may be wondering what your options are for repair. Traditional pipe replacement can be costly and time-consuming, but there is another option: pipe relining.

Pipe relining is a no-dig solution that involves installing a new lining inside the existing pipe, effectively creating a new pipe within the old one. While it may seem like a more expensive solution upfront, there are a number of factors to consider when comparing pipe relining costs to traditional pipe replacement costs.

Factors that Affect Pipe Relining Costs

The cost of pipe relining can vary depending on a number of factors. Here are some things to consider when calculating the cost of pipe relining:

Pipe Size and Length

The size and length of the damaged pipe will affect the cost of relining. Larger pipes or pipes that are longer may require more materials and take longer to reline, resulting in a higher cost.

Pipe Accessibility

The accessibility of the pipe is also a factor to consider. Pipes that are more difficult to access may require more equipment or labor to reach, resulting in a higher cost.

Type of Damage

The type of damage to the pipe will also impact the cost of relining. If the damage is extensive, it may require more materials or a longer repair time, resulting in a higher cost.

Pipes can suffer damage due to various reasons. The most common causes of pipe damage are corrosion, tree root intrusion, ground movement, and blockages.

Corrosion is a natural process that can occur in metal pipes over time. The corrosion process can be accelerated due to various factors such as pH levels, water chemistry, and the presence of chemicals in the water. Corrosion can cause leaks, cracks, and even pipe failure if left untreated.

Tree root intrusion is another common cause of pipe damage. Tree roots can grow towards a water source, such as a pipe, and penetrate the pipe walls, causing cracks and breaks. This can lead to leaks and blockages, and if left untreated, can cause complete pipe failure.

Ground movement is also a significant cause of pipe damage. This can be due to various factors such as earthquakes, landslides, and settling of the soil. Ground movement can cause pipes to shift, bend, and even break. This can lead to blockages and leaks, and if left untreated, can result in complete pipe failure.

Blockages are another cause of pipe damage. Blockages can occur due to various reasons such as the buildup of grease and other materials, foreign objects in the pipes, and even tree root intrusion. Blockages can cause pressure to build up within the pipe, leading to cracks, leaks, and even complete pipe failure if left untreated.

It is important to note that while these are the most common causes of pipe damage, there can be other factors that may cause damage to pipes. Therefore, regular inspection and maintenance of pipes are crucial to prevent any potential damage and to ensure the longevity of the pipes.

In the case of pipe relining, it is essential to identify the cause of the damage before proceeding with the relining process. This can help determine the appropriate solution to prevent any future damage to the pipes. For instance, if tree root intrusion is identified as the cause of the damage, tree removal or regular root pruning may be required to prevent future damage.

By identifying the cause of the damage and addressing it appropriately, property owners can prevent costly repairs and ensure that their pipes remain in good condition for many years to come.

Type of Lining Material

There are different types of lining materials available for pipe relining, and the cost can vary depending on the material used. Some materials may be more expensive but offer additional benefits, such as increased durability or resistance to corrosion.

Epoxy lining is the method used in pipe relining by Streamline Pipes, where a durable, waterproof liner is created inside the existing damaged pipe. This liner is made of an epoxy resin that is mixed with a hardening agent and then applied to the inside of the pipe. The epoxy liner is then left to cure and harden for several hours until it becomes a seamless, leak-proof coating that covers the entire inner surface of the pipe.

The epoxy resin used in pipe relining is a high-quality material that is resistant to wear, corrosion, and chemicals. It is designed to withstand high pressure and temperatures, making it suitable for use in various types of pipes, including those used for sewage and wastewater.

The liner material used in pipe relining is made of a flexible, synthetic material that can be molded to fit any size or shape of pipe. It is also UV-resistant, which means it can withstand exposure to sunlight without breaking down or deteriorating. This ensures that the liner material remains strong and durable, even when exposed to harsh weather conditions.

When it comes to the installation process, epoxy lining is a relatively straightforward process that involves only a few simple steps. First, the damaged pipe is thoroughly cleaned and inspected using a pipe camera to identify the location and extent of the damage. Then, a resin-saturated liner is inserted into the pipe, using compressed air or water pressure to push it into place.

Once the liner is in position, it is inflated to conform to the shape of the existing pipe, and a curing process begins. This involves applying heat or steam to the liner to activate the epoxy resin, which then bonds to the interior of the existing pipe, creating a new, seamless surface.

Overall, epoxy lining is a highly effective method for repairing damaged pipes, and it offers several advantages over traditional pipe replacement methods. For one, it is less invasive and disruptive, as it doesn’t require extensive excavation or demolition work. It also tends to be quicker and more cost-effective than traditional methods, as it can be completed in a matter of hours, rather than days or weeks.

In addition, epoxy lining provides a long-lasting and reliable solution for damaged pipes, as the liner material is resistant to corrosion, wear, and chemical damage. This means that once the lining is in place, the pipe should remain free from leaks and other issues for many years to come.

Comparing Pipe Relining Costs to Traditional Pipe Replacement Costs

While pipe relining may seem like a more expensive solution upfront, it’s important to consider the long-term costs and benefits when comparing it to traditional pipe replacement.

Traditional pipe replacement involves digging up the old pipe and replacing it with a new one. This process is time-consuming and can be disruptive to your home or business. It also requires extensive labor and equipment, resulting in a higher cost overall.

In contrast, pipe relining is a no-dig solution that is much less disruptive and time-consuming. While the upfront cost may be higher, the long-term benefits can make it a more cost-effective solution overall. Additionally, pipe relining can extend the life of your pipes, reducing the need for future repairs and replacement.

Is Pipe Relining Worth the Investment?

Ultimately, whether pipe relining is worth the investment will depend on your specific situation. It’s important to consider factors such as the age and condition of your pipes, the extent of the damage, and your budget when deciding between pipe relining and traditional pipe replacement.

If you’re unsure about whether pipe relining is the right choice for you, it’s best to consult with a professional plumber. A qualified plumber can assess your situation and provide you with an accurate estimate of the cost and benefits of pipe relining.


Pipe relining can be a cost-effective and long-lasting solution for damaged or broken pipes, but it’s important to consider the upfront cost as well as the long-term benefits. By understanding the factors that impact pipe relining costs and comparing them to traditional pipe replacement costs, you can make an informed decision about which option is best for your home or business.

Frequently Asked Questions

What Is Pipe Relining?

Pipe relining is a trenchless pipe repair method that uses a resin lining to fix pipes. The existing pipe is cleaned and inspected, then lined with a resin material that’s cured to form a new pipe within the old pipe. With Streamline Pipes, you can expect 60 years of service life out of your relined pipes!

If The Pipe Has Collapsed Can It Be Relined?

If your pipe has collapsed partially, we can reline it. If the sewer or stormwater pipe is fully collapsed then this will require, digging and a pipe replacement, to fix it correctly and costs more in labour. The pipe is impregnated with an epoxy Liner. Once cured, this creates a ‘new pipe, within the old pipe’. Very similar to a medical ‘stent’.

The benefits of using pipe relining for a cracked or partially collapsed pipe include:

  • No digging required
  • Permanent solution
  • Cost-effective
  • Less disruption – you can use your pipes within hours not days.
  • Landscaping, flooring, and driveways are not damaged.

How Long Does Pipe Relining Take?

It depends on many factors, including the size of the pipe and the access to this pipe. In most cases, your pipe can be relined in a few hours.

If you need the work done as a matter of urgency then StreamlinePipes can be there the next day after the quote is provided.

How Long Does Pipe Relining Last?

Pipe relining is a long-term solution. The pipe lining can last just the same if not longer than replacing in with a new PVC Pipe. Once it is in place you don’t have to worry about repairing or replacing it for years.

Relined pipes are more cost-effective than replacement of the entire pipe, which can be very expensive. Relining leaves your property intact, so there’s no need to dig up your yard or pathways or remove any landscaping features. You won’t even notice when our qualified plumbers are onsite!

StreamlinePipe relining saves money in the long run because:

  • It doesn’t require digging up yards and pathways in order to replace pipes that may be causing water damage under concrete slabs or driveways
  • We guarantee our work for 60 years – an industry first

How Does CIPP Relining Work?

Cured-In-Place-Piping (CIPP) relining is a method of repairing pipes that involves injecting a high-density polyurethane material into the pipe. The material hardens and forms a new pipe within the old pipe. This method of pipe repair was pioneered by Streamline Pipes and Drains over 31 years ago.

Does Pipe Relining Need To Be Done By A Specialist?

Absolutely.  Pipe relining requires specific equipment and training. The no-dig pipe repair solution is not taught at Tafe. Relining training is learnt ‘on the job’ and can take decades to perfect. It is worth thinking ‘will the plumbing company be around for 2o years to fix any possible problems”?

There are many companies out there claiming to be able to do this work effectively, but no one can match the quality and expertise of Streamline Pipes and Drains as they are only just beginning and Streamline has be Relining for over 31 years.

Is pipe relining approved by Australian standards?

Yes, pipe relining is approved by Australian standards. In fact, AS3600 (2016) and its subsequent revisions include requirements for the use of pipe relining as a method of remediation in both stormwater and sewer systems.

AS3600 is a set of standards for stormwater and wastewater systems that have been developed under the auspices of Standards Australia New Zealand (Standards NZ). The following standards apply:

  • AS3600 – general requirements for design, construction, operation, maintenance and decommissioning of water supply schemes including wastewater treatment works
  • AS3600.1 -2018 – quality management system standard for health sector facilities; quality management system standard for medical devices; other technical regulations made under Food Act 2014; classifications under Industrial Chemicals (Notification & Assessment) Act 1989; classification under Ozone Protection & Synthetic Greenhouse Gas Management Act 1989; environmental performance standards under several statutes including Hazardous Substances (Emergency Response Management) Regulations 2007; risk assessment framework under Hazardous Substances (Emergency Response Management) Regulations 2007

Can Root Intrusion Be Fixed With Pipe Relining?

Root intrusion is the result of tree roots growing into the pipes. Pipe relining is a perfect preventative solution when roots have invaded your sewer pipes, as the use of a High-Pressure Water Jet and inspection camera, is the precursor work required in order to clean and clear the blockage. Once this is done, then the StreamlinePipes relining system is able to install the pipe liner and get your pipes working again, with tree roots permanently removed from that part of the drain system.
