Tree root intrusion can cause slow drains, blocked drains and sewer backups and lead to a major disruption in your household in Sydney. If your property has cracked pipes or structurally weak joints, or there are plants near the drainage system, roots often find a way into damaged drain pipes. If you need tree root removal in Sydney, contact us.
First, we find where the roots have entered through CCTV inspection, understand the extent of damage and recommend an appropriate solution. Depending on the extent of damage, we suggest solutions like eel, sewer jetting, or robotic cutting.
If a drain pipe has a tiny crack or a loose joint, water can escape into the surrounding soil and attract nearby roots and roots can penetrate small cracks and enter the pipe. Tree roots are primarily looking for water and nutrients. Once inside, they keep growing towards moisture and can form a large root mass. This catches more debris and waste and slows the flow of water.
Even a small amount of water leaking from an old pipe can attract nearby roots. The root hair can enter through small cracks and gaps. As the roots grow inside the pipe, they can catch toilet paper, grease, dirt and other organic matter and create recurring blockages.
Older clay pipes are more likely to develop cracks and loose joints as they age, while PVC pipes are less likely to have this problem when they are in good condition. However, roots can still enter if the pipe or a joint becomes damaged by chance and develops cracks. Sydney has dense residential areas with mature trees nearby. Some properties also have earthenware or iron pipes with cracks, which makes it easy for the roots to enter.
Roots thrive particularly when they find a steady source of moisture. Once they find an entry point into a sewer pipe, they can easily continue growing inside it. A tiny crack or loose pipe joint often seems like a small problem at first, but it can eventually lead to repeated blockages in the long run.
A drain that keeps blocking may have tree roots growing inside the pipe. These are some of the common signs to look out for:
Even after clearing it, the blockage keeps coming back after a while.
Sinks, showers or floor drains take longer than usual to empty.
The drain makes bubbling or gurgling sounds when water is running.
You may notice an unpleasant smell coming from the drain.
Water flowing back through a sink, shower or floor drain is another sign.
When several drains are showing signs of slow drainage at the same time, the blockage might be caused by tree roots.
Inner West Sydney has Federation-era homes with older drainage system clay pipes. These pipes can develop small cracks or loose joints because of the lack of maintenance, making it easy for tree roots to enter. New houses might also face the same thing if they have cracked pipes.
Many homes are in close proximity to mature trees with spreading roots. Naturally, roots have a tendency to grow near sewer lines, causing severe blockage.
Tree roots are naturally drawn to water. Due to this, a leaking sewer pipe can become an easy source of moisture for nearby roots. Once they find the pipe, roots can enter through a tiny crack and continue growing inside the sewer system.
New trees can also cause problems as their root systems grow over time, especially when they are planted close to underground pipes. The tree may be small when it is planted, but its roots can spread much further as it becomes established.
We first use a CCTV inspection to check where the roots have entered, how much root growth is inside the pipe and whether the pipe is damaged or beyond repair. Once we know what is going on inside, we can choose the right way to clear the roots.
The method mainly depends on the extent of root growth and the degree of damage. For smaller roots, we may use an electric eel, while larger root growth may need high-pressure sewer jetting with root nozzles or robotic cutting. Our team gets into the root of the problem and recommends a solution that is suitable.
An electric eel can cut through smaller roots and clear them from the drain. It is usually suitable when the root mass is not too dense and there is still enough space inside the pipe for the equipment to work. It has a rotating cable and cutting head that breaks through the blockage to restore the water flow. Though it has the capacity to cut through certain root blockages, some build-up might still remain in the pipes.
Sewer jetting or hydro jetting Sydney uses high-pressure water to cut through roots using root nozzles, wash them out of the pipe and clear the blockage. The mechanism is simple but effective. The specialised nozzle is inserted into the damaged area of the pipe while the high-pressure jets work effectively on the root mass, break apart the blockage, and the reverse flow cleans the inside walls of the pipes thoroughly. The roots are flushed out and the water starts flowing normally. The water pressure can be controlled depending on the condition of the damage and the quality of the pipes. Earthenware or clay pipes might not be able to withstand high-pressure jetting.
Robotic cutting is used when there is a large root mass or heavy root growth that needs to be cut out from inside the pipe. It is essentially a tiny cutting machine that is inserted into the damaged pipe with growth. The whole process is controlled by a technician outside through CCTV camera inspection and an air hose. This type of mechanical root cutting can be useful for severe blockages that are difficult to clear with an electric eel or sewer jetting. The robot cutting method is used to cut through a huge mass of tree roots and remove stubborn blockages without any excavation. However, it is not suitable for pipes which have collapsed completely.
Cutting the roots removes the blockage, but it is not a permanent solution. It breaks through tough root masses causing obstruction, but it does not always fix the reason the roots got inside the pipe. If there is still a tiny crack or loose pipe joint, new roots can enter through the same spot because the opening has not actually been repaired.
This means root cutting can sometimes be a temporary fix rather than a permanent repair. If the pipe has cracks or leaks, roots may return within 12–24 months, although the timing depends on the pipe, the tree and the amount of root growth around the damaged area.
If the same roots keep coming back, clearing them repeatedly can become costly. Finding and fixing the entry point may save money over time because you are dealing with the cause of the blockage instead of paying for the same process of temporary root removal again.
A CCTV inspection can show whether the pipe needs more than root removal. It can also help us check for cracked pipes, a broken pipe, loose joints or other damage that may need a permanent repair.
If roots keep entering through the same damaged section, pipe relining Sydney may be an option. It repairs the inside of the existing pipe without needing to dig up the whole area, which can be useful when underground pipes run below gardens, driveways or floors. The process uses a synthetic liner that is placed inside the existing pipe and then cured in place. This creates a new pipe inside the old pipe and gives the inside surface a new layer that covers the gaps roots were using to get inside.
Modern composite resin technology allows the liner to cover suitable cracks and damaged joints. The result is a seamless pipe surface that closes the entry points where tree roots were getting into the sewer line.
Pipe relining is not suitable for every old pipe. If the pipe has collapsed badly, moved out of position or lost too much of its structural foundation, replacing it with a new pipe may be a suitable permanent solution.
A CCTV drain inspection helps us understand the condition of the pipe before recommending a permanent repair. This means the repair can be based on the actual plumbing problem rather than simply clearing the roots and waiting for them to return.

Responsibility for tree roots in pipes depends on where the affected section is located, who owns that part of the drainage system and the circumstances.
Read our guide for a detailed explanation of responsibility and repairs.
Chemical treatments are sometimes used to control root growth inside drains, mainly when the aim is to slow down new growth after the roots have been removed. They may help in some situations, but they do not repair a cracked pipe or close the entry point where the roots got inside.
Chemical foam can also be used to treat root growth inside some sewer pipes. It can reach parts of the root mass that remain inside the pipe, but it should not be treated as a permanent fix when there is still a crack or loose joint.
Rock salt is another treatment that is sometimes suggested for roots in drains. It does not repair damaged plumbing pipes or stop tree roots from entering through the same opening, so it should not be treated as a permanent solution.
If roots keep coming back, the important question is why they are getting inside the pipe. A CCTV inspection can show whether there is a crack, loose joint or another problem that needs to be repaired and help us recommend which is the best solution.
Root barriers can help manage root growth when planting new trees near underground services. They may help stop tree roots from reaching certain areas, but they cannot remove roots that are already inside a sewer line or repair a damaged pipe.
The cost of tree root removal is usually from $400 to $700. It usually depends mainly on the size of the root mass and where it is located inside the pipe. The condition of the pipe, how easy it is to access and the equipment needed to clear the roots can also affect the cost.
A smaller blockage may only need an electric eel or another basic root removal method, while a severe blockage may need high-pressure water jetting or robotic cutting. This is especially the case when there is a large root mass inside the pipe.
The cost can also increase if the roots have damaged the pipe. If there are cracked pipes, a broken pipe or a damaged joint, you may need a permanent repair such as pipe relining or pipe replacement. See whether pipe relining is worth it compared with digging up the line.
It is worth looking at the cause of the problem instead of only clearing the immediate blockage, and if the same roots keep returning, fixing the entry point may be a more cost-effective solution than paying for repeated plumbing services. We inspect the problem through CCTV inspection and give upfront estimates for tree removal methods, which is reflected in the final invoice.

Yes, tree roots can come back after cutting. If the entry point is still open, roots may grow back into the drain, sometimes within 12–24 months depending on the pipe, tree and surrounding conditions. If the pipes are structurally damaged, they need to be relined or replaced to prevent future chances of tree root intrusion.
Not always. Removing the tree may stop new root growth from that tree, but existing roots can remain inside the pipe and a damaged pipe will still need to be repaired. Pipe relining or replacement might be a more sustainable option that will fix the pipe and prevent the roots from coming back.
Pipe relining creates a sealed surface inside the existing pipe and closes the gaps roots were using to get inside. How long it lasts depends on the liner system, installation and condition of the existing pipe. Relined pipes generally have a lifespan of 50 years, if installed with care.
The right method depends on the amount of root growth and the condition of the pipe. Electric eels, high-pressure water jetting with root nozzles and robotic cutting can all be used where the situation is suitable. But robotic cutting is the best method for obstruction caused by dense tree root masses leading to repeated blockages.
