A resin liner cured inside the existing drain, sealing every joint. And the garden, the path and the verandah tiling stay exactly where a hundred years put them.

Relining is usually argued on convenience. No trench, no mess, quicker. On most blocks that is a preference rather than a reason.
In these streets it is a different conversation, because of what a trench would have to go through. A garden that took forty years to establish. An original path. A tessellated verandah floor. A frontage inside one of Burwood's four residential conservation areas.
None of that is a shopping trip. Some of it cannot be honestly replaced at all, and the council is strict on conservation areas and tree preservation, so removing a significant tree to reach a pipe is a discussion with council rather than a decision made on the morning.
Relining goes in through existing access points and touches none of it. The pipe is repaired and the surface above stays exactly as it was, which on this housing is worth considerably more than the difference in the plumbing.


On a retrofitted Victorian run, a quote given without footage is a guess. And here the guess gets paid for in garden rather than in pipe.
A mature garden, an original path, a tessellated verandah, a listed frontage. Excavation goes through all of it and reinstatement is skilled work.
Some of it cannot be genuinely replaced, which changes the comparison between methods entirely.
Four residential conservation areas plus strict tree preservation under the council's LEP and DCP, and the Appian Way is state heritage-listed.
You can always repair your drain. What needs care is opening a listed frontage or removing a significant tree to get to it.
Because the drainage was retrofitted into a finished building, it frequently skirts the house or doubles back rather than running straight.
Bends affect how a liner is installed and how a job is priced, and they are another reason nobody should quote one of these without filming it first.
The cured liner is continuous along the lined section, so there are no joints left to open and no entry points for roots.
On a line assembled in short lengths well over a century ago, that is the entire repair rather than a partial one.
A collapsed or crushed section has to be excavated and replaced. A liner needs sound pipe to press against.
We price that honestly alongside, including putting the surface back, so the comparison is a real one rather than a sales pitch.
Quoted at a fixed price off the camera footage, with excavation priced beside it including reinstatement. These are indicative 2026 ranges.
The run filmed and followed. Credited against the reline if you proceed.
One failed joint or a short damaged length, sealed without touching the rest.
Priced on length, diameter and bends, and these runs generally have bends.
The line taken back to clean wall so the liner forms properly against it.
Including what reinstating the surface would actually cost, so you can compare honestly.

We film it and mark the route, because on a retrofitted line nobody knows where it goes until somebody looks.

The reline, and excavation with reinstatement of whatever is on top, so the comparison is honest rather than rhetorical.

Roots cut, the line cleaned back, then the liner drawn through and cured. Nothing above ground is opened.

The finished run recorded end to end so you can see every joint is sealed.
Ask what the reinstatement costs, not just the excavation. On a heritage frontage that is usually the larger half of the bill.

A resin-soaked liner is drawn through the existing drain, inflated so it presses against the pipe wall along its whole length, then cured until it hardens. What you get is a continuous pipe formed inside the old one, with no joints along the lined section. Joints are where roots enter and gaps open, so removing them is the point. The old pipe stays where it is and acts as the mould, which is why nothing above it is disturbed.
Because of what is sitting on top of the drain. In these streets that can be a mature garden that took decades to establish, a tessellated verandah floor, an original path, or a frontage in a heritage conservation area. Replacing any of that is not a matter of ordering materials; some of it cannot be genuinely replaced at all. Relining goes in through existing access points and none of it is touched, which is a far larger saving than the plumbing difference.
It affects the surface, not the pipe. Burwood Council maintains four residential conservation areas and is strict on tree preservation under its LEP and DCP, and the Appian Way is state heritage-listed. That does not stop you repairing a drain, but it does mean excavating a listed frontage or removing a significant tree is a conversation with council rather than a decision you make on the day. Avoiding the excavation avoids the conversation.
Usually, and it is most of what we line here. What rules it out is a section that has genuinely collapsed or been crushed, or one so far gone there is nothing left to form a liner against. The camera settles it before anyone quotes and the footage is handed over either way. If lining will not work we say so rather than selling you one that fails.
It is normal here and it is manageable. Because the drainage was retrofitted into a finished house, it frequently skirts the building or doubles back rather than taking the direct route. Bends affect how a liner is installed and they are part of what we price from the footage. It is also the reason a quote given without a camera on one of these houses is not worth much.
A sectional patch is usually a few hours; a full run to the boundary is generally most of a working day, and you get the window before we start. Set that against excavating a long, indirect run across a large block, which is days of open ground plus reinstating a garden and possibly a heritage surface afterwards.
A sectional patch over one failed joint is about $900 to $2,200. A full run to the boundary is usually $3,500 to $7,000 depending on length, diameter and how many bends it has, and these runs do have bends. A camera inspection is $250 to $450, credited against the reline if you proceed. We price the excavation alternative alongside it, including reinstatement.
Tell us whether anyone has filmed it, and what sits on the surface above the run. A lawn and a tessellated path are very different conversations.
