Pipe Relining Cost – Is It Worth It?

What Is Pipe Relining, And Is It Worth Relining My Pipes?

Simply put, Pipe Relining creates a pipe within the existing pipe. At Proximity Plumbing, we use a two-part epoxy that’s pulled through the pipe and expanded to leave a hard fibreglass shell that can’t be penetrated by roots. These new pipe lining systems are up to 4 times stronger than a new PVC pipe and are perfect for sewer pipe repair.

Pipe relining is the best solution for repairing difficult and damaged pipes. Known as a “no dig” solution and considerably less impactful than any other pipe repair options. It’s quiet, quick and clean, which is why it’s becoming the go-to service for our eastern suburbs clients who are looking for a long term solution that won’t disrupt the home or garden.


Here Are A Few Factors That Generally Impact The Cost Involved In Pipe Relining

1. The Size Of The Pipe

We have the capability to reline small to very large  pipes, as  you can imagine this heavily affects the end cost.

2. The Length Of The Pipe

Like most things, the more you need, the more you pay. A job with only 2 meters of pipe relining is going to cost a lot less than a job with 20 meters! From our CCTV inspection and measurements gained from the inspection, we’ll be able to know just how much piping you’ll need.

3. The Ease Of Access To The Pipe

Whilst pipe relining has the advantage of “no digging or excavation required” in some instances, we will need to dig a small hole. If this is needed, it can affect the price of the job. Especially if we need to dig and install new piping to access the pipes we’re trying to reline.

4. The Existing Condition Of The Pipe

The condition of the existing pipe plays a role in the price of the job. If it is full of tree roots or silt and will require many hours of clearing with a high-pressure water jetter, then this may affect the price.

Same thing if the drain is very damaged as usually there will be some additional work required to prepare the pipe before relining.

5.    The Location Of The Site

Unfortunately, pipe relining equipment is generally very big and heavy. So if getting the equipment to your location is tricky (and some residences in the eastern suburbs are) then we’ll need more manpower to help us get it to your site. difficult it will take additional time and will likely require more staff to help carry it there

 The Method We Choose To Reline The Pipe

There are three primary stormwater and sewer relining methods: inversion, patch, and drag-in. Below, we detail each technique and factors that can influence the cost of sewer relining.


The inversion method is the most effective option for preventing future blockages. It's typically used for relining sections longer than three continuous meters. This process involves inserting a liner and resin into the drain using an inversion drum, a sophisticated and costly equipment that ensures superior results. The resin is applied on the outside of the liner, bonding with the existing pipe to seal all cracks and joints, thus preventing tree roots from infiltrating.

Patch Relining

Sectional patch relining is ideal for repairing one or a few specific spots, especially when the rest of the pipeline is in good condition, or the property owner wishes to address only the most damaged areas. The cost of patch relining is calculated per patch rather than per meter. Like the inversion method, the resin is on the outside, bonding to the existing pipe and ensuring a secure repair.


The drag-in method is used in situations where an inversion drum cannot be employed (though this is rare) or when relining needs to start further along the line with no immediate access. However, this method has its drawbacks and generally offers a shorter lifespan. The resin is on the inside of the liner, which can result in an improper bond with the existing pipe, leaving old cracks and joints vulnerable to tree root intrusion. Additionally, the liner's plastic layer can create gaps between the old and new pipes, allowing tree roots to infiltrate if the liner or installation technique is incorrect (a common issue). Furthermore, drag-in relining requires two access points, potentially necessitating additional excavation and increasing the overall cost.


 7.    The Number Of “Junctions” Which Need To Be Relined

The number of junctions (branch lines) within the relined section of pipe, will increase the price. It’s another reason why it’s so important to have your CCTV pipe inspection before deciding to reline – your plumber will be able to see just how many junctions he or she is dealing with. Junctions are important because if a junction is “tree root affected” BY LAW a junction patch must be installed. This is because without it the tree roots will gain access to the drain again!

8.   The Quality Of The Pipe Relining Materials

Like all industries, there are high and low-quality products on the market, so this obviously affects the trenchless sewer repair cost. Because we have been pipe relining for many years, we have been lucky enough to test 100’s or products from all over the world. From this extensive test and measure process, we have found the most superior products available and only use them on our jobs.

Our materials are purchased from RSM Lining Supplies, which is one of the most recognised and reputable suppliers in the world. They are a company from The UK but also based in Australia, USA and Canada.  All of their products are made in Germany, France, the UK, or the USA and are 100% Australian Watermark approved.

9.    The Risk Involved

Pipe relining is a job that can come with very high risk, when a mistake is made (this is another reason to check up on the plumber you’re engaging to take on the job – see below for more info). The main risk factor is that in pipe relining, there are no second chances, there is one chance at installing the new pipe correctly. So, you better know that the team you have on the job are experts at pipe relining.

10. The Decision Of Every Plumbing Company On What They Charge

This is generally what will create the biggest differentiation in the price. The reason being is that some companies are expensive, cheap, or quoting to do different work. So, it’s very important to properly compare quotes and ask as many questions as possible.

Your best ally in a cost conversation is information. Ask the company as many questions as possible about the time involved, labour costs, hourly costs (if any) possible issues with access to the site, materials used, quality of materials, etc. Get them to take you through why the costs vary (from one company to another). Also, a good idea to shop around and get a few quotes so you can feel comfortable.

Does Pipe Relining Cost Less Than Replacement?

Pipe relining is generally more expensive than replacement. The investment into pipe relining is significant due to the extensive equipment, the materials and the intensive training required to do the job. Pipe relining is not taught at TAFE. Each relining business must train their own staff. It can take up to 12 months for a qualified plumber to run a pipe relining job autonomously. This significantly adds to the cost of doing business.

Restoration Costs

That being said, pipe relining is less expensive if you take into account the costs of property restoration: The replacement of pipes requires excavation. With excavation comes cost because whatever is above ground needs to be put back. This could be paving, landscaping, retaining walls, bathroom tiles. Not only can this be expensive, but it is also time consuming having to coordinate the tradesmen to do the work.

The Cost Of Pipe Relining Vs Pipe Replacement

There are many factors that come into the cost of both relining and repairing. There’s rarely going to be a simple price point for either of these services. If your damaged pipes are underneath building foundations, it means you’ll need to do a full excavation job to reach these pipes. Not only will the excavation be costly, but you’ll have to repair everything that needs to be removed in the process including concreting, tiling and more. When it comes to pipe relining the costs are also dependent on a lot of factors, including access, type and size of the pipe and the amount of damage. Often the costs of pipe relining are considered higher than pipe repair. But when you think about everything that comes along with pipe repair – excavating, re-building, re-landscaping, not to mention how long all this takes. So, you’ll also need to take into account that down time and what that will cost your business during the excavation process.

What Affects Pipe Relining Sydney Costs?

The cost for relining your pipes is completely dependent on many variables of your property. So, without our free inspection and obligation free solution plan, it’s hard to put a price on the job.

If you’re asking, “Is Pipe Relining Worth It?” it’s important to factor the costs of digging vs the cost of completing pipe relining. On average, pipe relining costs will vary between $450 – $1000 per metre. You’re probably wondering why the cost of this procedure varies and this is a very common but good question As far as the costs go, there isn’t a definitive answer. The price will depend on a variety of factors, including:

  • Size Of The Pipe
  • Location Of The Pipe
  • Accessibility Of The Pipe
  • The Condition Of The Pipe
  • The Diameter Of The Pipe (Smaller Diameter Pipes Are More Expensive)
