How Much Does Pipe Relining Cost?

One of the first things customers want to know is “How much does pipe relining cost?”. As a general rule of thumb it will cost you $400 – $1000 per meter. However, on this page we will explain everything you need to know about what affects the price and provide you with a ‘Price Estimate Calculator’ so you can calculate approximately what your stormwater or sewer pipe relining cost would be. 

The reality is, without visiting your property and inspecting your drain with a CCTV drain inspection camera, no company will give you a 100% confirmed drain relining cost, they will only be able to give you an estimate.  

What affects Pipe Relining Sydney Costs?

1. Size of Pipe to be Relined  

We have the capability to reline small to very large  pipes, as  you can imagine this heavily affects the trenchless pipe repair cost. The pipe relining  sizes we are able to reline is 32mm, 40mm, 50mm, 65mm, 90mm, 100mm, 150mm, 175mm, 225mm, 300mm, 375mm, 450mm, 525mm, 600mm, 675mm, 750mm, 825mm, 900mm, 1050mm, 1200mm and 1350mm.

2. Length of Pipe

A convenient part of our trade is we can calculate the pipe relining cost per meter. Once we know the size of pipe and the amount of meters to be relined we will be able to give you a meterage price. Pipe relining pricing is no different to anything else, ‘the more you buy the cheaper it gets’. Obviously if we are relining 5 meters vs 50 meters the per meter price will be different.

3. Method

There are 3 main methods for stormwater and sewer relining. Inversion, patch and drag in. Here are the methods in detail and what can affect the sewer relining cost:

Inversion This is by far the best option if you never want to have a blocked drain again. This technique is generally used when more than 3 continuous meters require drain relining. The liner and resin is inserted into the drain by means of an Inversion Drum, this is a very high quality and expensive piece of equipment that guarantees the best possible end result. The resin is on the outside so it bonds to your existing pipe sealing all the cracks and joints ensuring tree roots have no chance of re-entering the pipe.

Patch Relining –  Sectional patch pipe relining is best used when there are only 1 or a few spots that need repairing and the rest of the pipeline is in good working order or the property owner would only like to repair the worst affected areas. The pipe relining cost is based on a per patch basis, not per meter. The resin is also on the outside which bonds to the existing pipe.

Drag in – This is an option if the job is not possible with an inversion drum (very uncommon) or if the reline needs to start further down the line where there is no access. However, it does come with risks and generally lower life expectancies. The main issue is that the resin is on the inside of the liner, meaning that it will not bond properly to the existing pipe and seal all of the old cracks and joints that tree roots gain access through. It has a layer of plastic up against the old pipe which gives tree roots an opportunity to work their way in between the two pipes and cause problems down the track if the incorrect liner or installation technique is used (very common). The other disadvantage is that you need 2 access points which may result in additional excavation which will add to the sewer lining cost.

4. Junctions (branch lines)

The number of junctions (branch lines) that have been relined over will increase the price, which is one of the main reasons it’s hard to quote ‘per meter’ without inspecting the pipeline with a drain camera. This is because each junction will need to be cut out with either a Picote Cutter or Robotic Cutter and if that junction was tree root affected then by law a junction patch must be installed, otherwise the tree roots will gain access to the drain again. Many companies will skip this step so their pipe relining Sydney cost can appear more competitive, so if you notice in quotes that other companies have included junction patches and another has not you will need to ask a few questions.

5. Materials Used

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.

6. Risk

Pipe relining is a job that can come with very high risk, not life-threatening risks, just the kind that if an error is made it could cost the company a week fixing it. What makes it risky is as soon as you mix the two-part resin together it will start to set, because of this we only get one shot at installing the liner properly as it really is a race against the clock. There are no second chances in pipe relining.

Many companies steer clear of risky relines, we actually thrive on them! However, if there is a lot of risks involved a risk factor must be applied to the quote which will increase the trenchless sewer line repair cost. This is applied by companies just in case the job has delays and takes longer than expected.

    7. Location

    Location is another factor that will affect the price. Pipe relining equipment is generally very big and heavy. So if getting the equipment to that location is difficult it will take additional time and will likely require more staff to help carry it there. For example, if we are working in the basement of a shopping centre/large building and the only way to get down there is to carry it all down by hand, this will be a higher pipe relining cost Sydney then if the reline is taking place in the front yard of a normal residential block of land. 


    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. Here are a few things to help. 

    Expensive company: There are many criminal companies that take advantage of people and will try and charge customers up to 10x the price it actually should cost. They will claim things against the other quoting companies like ‘They are not experienced, they have a bad name in the industry, their products are not WaterMark approved, etc’. It’s best to do your own research instead of believing every word companies like this tell you. If you’d like to find out more information on these companies and how to pick them, click here.

    Cheap Company: Like anything, if the price seems too good to be true, then it probably is. It’s important to find out why this company is so much cheaper than the other companies. Are they relining the same amount of meters? Are they installing junction patches? Do they have the same amount of patches? Or on the other side of the spectrum, are they a fair price and the other quoting companies are extremely expensive? Ask questions and do your own research.

    9. Access

    Even though we are very proud of our ‘No Dig’ technology, the reality is that sometimes we have no other option except to dig a small hole to create an access point to reline from. If this needs to be done there will be a small fee added for the labour required to dig the hole and install then install the appropriate PVC pipe and fittings we can reline through.  As this will take additional time and more materials need to be used this will increase the drain relining cost.

    10. Condition Of Existing Pipe:

    The condition of the existing pipe plays a role in the price of the job. If it is completely 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. It is very important that the drain is completely clean before relining. 

    If the drain is very broken or dislodged, there may be some additional work required to prepare the pipe before relining. It is important to take these steps in order to get the best possible, long-lasting end result.

    In some cases the drain can not be relined, this is generally when the pipe has completely collapsed. If this is the case there is no option except to dig up that section of pipework. If your plumber shows you a video of your pipe completely broken looking like it may collapse at any second, you should take this seriously.

    11. Guarantee

    How long does the company guarantee its installation for? This all depends on what products they install and if they back their installations. The common amount is 25 – 35 years, some companies are offering 50 years, but then there is Revolution Pipe Relining that offers a LIFETIME Guarantee, we are the only company in Australia that offer this. The reason we can offer such a long guarantee is that we know our installs are perfect, as we do the installations ourselves and only use the highest quality materials available. Some companies need to offer a lower guarantee as they have younger inexperience installers, inferior materials or they completely outsource the work so its too risky to offer long guarantees.

        What is damaged?

        The section of pipe that is being relined determines the trenchless sewer replacement cost. For example, relining a boundary trap is more difficult and requires different techniques to relining a straight piece of pipe. Installing junction patches is more difficult and takes more time than installing a straight patch.

        The reality is, without visiting your property and inspecting your drain with a CCTV drain inspection camera, no company will give you a 100% confirmed drain relining cost, they will only be able to give you an estimate.

        Our house sewer line was regularly being blocked by tree roots. Based on the excellent Google reviews and internet information provided by Revolution Pipe Relining, we knew that this was the company to approach. Right from the onset, the service given by Chris and his team was exceptional. They were all highly professional, punctual and tidy. There may be cheaper pipe relining companies out there but we wanted a quality, long-term solution and I have absolutely no doubt that we got it.

        Chris went beyond what was required to diagnose and clear a blockage in the sewer. He then went further and did more checking upstream from the original blockage to check . In doing so he found another issue. That type of thoroughness is expected but not always delivered. A great job by a nice , decent bloke. Thks Chris

        We have had ongoing issues with tree roots invading sewer line. Revolution pipe relining came out and assessed the situation and recommended a boundary trap pipe replacement at a reasonable price. We had started on it early in the big rain this year and had to delay due ground being waterlogged. Chris keep us informed with regular updates and once ground had dried out enough his team did a superb job and cleaned up afterwards themselves. Chris and his team were very professional and friendly in their approach and I would highly recommend them.

        Chris and the guys from Revolution Pipe Relining, made what is a stressful situation as seamless and stress free as possible. Chris was thorough with his free inspection, eliminating the guess work on the final and very competitive price. Daryl and his guys did a professional job relining our sewer party line, and managed the five different parties involved limiting their inconvenience caused by these urgent plumbing works. I highly recommend Revolution Pipe Relining if you are suffering constant blockages, and ongoing sewer unblocking costs due to tree roots in older terracotta pipes. Joe from Paddington

        With all the heavy rains in Sydney in Feb/March 2022, we realised we had issues with the stormwater pipes at our property. The team were out to have a look promptly, looked at and considered various options to address the issues and advised on the best course of action (which wasn't the most expensive option, but the most practical and pramatic one). Once we agreed to proceed, the team were prompt in booking in a time and date to start the work, were onsite on time, did a great job and communicated well on the progress and next steps and timings. The job was fully completed in excellent time and I am very happy with the work by the team.

        The team at Revolution Pipe Relining did an a great job at repairing a difficult to access cracked 3 way pipe replacement by my front door. It required a lot of digging and replacement of pipes, junctions and relocation of the overflow. They offered a fair price, were on time and worked diligently to ensure minimal disruption. In the process another issue unrelated was discovered that they were able to show me and then did a fabulous job fixing it by relining the pipe and solving a critical issue that was affecting the house foundations. A huge thank you to Chris and his team. I highly recommend.
