Relining In
Alexandria
We camera the line first, show you what is actually wrong, and then tell you whether relining is the right answer. Often it is. Where the pipe has collapsed or lost its fall, it is not, and we will say so rather than sell you a liner that disappoints.

When A Liner Is The Right Repair In Alexandria
A resin-saturated liner is drawn into the existing pipe through an access point, inflated so it presses against the wall, and cured until it hardens. What you are left with is a continuous pipe inside the old one, with no joints along its length and a slightly smaller bore than the original.
Nothing is excavated, and the cured surface is smoother than the clay or concrete it lines, so flow is typically maintained or improved despite the small loss of diameter. On a property where a driveway, mature garden or paving sits over the line, that is the whole argument.
Grease lines, and what relining does and does not solve
A food premises line narrows with hardened fat long before it fails structurally. Relining a greased line without addressing the grease simply gives you a smooth new surface to coat, and the interval to the next problem barely changes.
The right sequence is jet it clean, camera it properly, and then decide. If the barrel is sound the answer may be a service schedule rather than a liner. Where the camera shows cracks or open joints under the build-up, relining is worth doing and the smoother bore genuinely slows re-accumulation.
Stormwater lines are relinable too
Alexandria once drained through Shea’s Creek, today’s Alexandra Canal, and its flat blocks still shed stormwater slowly, so older drains overload in a downpour.
Most people associate relining with sewers, but stormwater suffers the same failures and reline just as well: cracked lengths, open joints, roots, and sections that have silted because the fall has flattened. On a property that floods in every serious downpour, the line is often the reason rather than the rain.
The camera run matters more here than anywhere. Clearing a surcharging pit at the height of a storm tells you almost nothing; the same line inspected on a dry day tells you whether you have a blockage or a defect.
Why earthenware is the ideal host for a liner
Clay and earthenware sewer lines laid beneath the cottages and factories around Botany Road and McEvoy Street are now a century old, and cracked joints are the suburb’s number-one blockage trigger.
Clay is rigid, round and predictable, and that geometry is exactly what a liner wants. The resin sleeve cures hard against a barrel that holds its shape, and the short pipe lengths that make clay joint-heavy are the same joints the liner seals in one pass.
So the material that causes the most recurring blockages in older streets is also the easiest to repair properly without digging. That is a genuinely lucky combination and it is why relining suits this housing stock so well.
Keeping the tree and fixing the drain
Removing a mature tree is expensive, often needs approval, and frequently does not solve it: the roots already inside the pipe do not leave when the trunk does, and the joint is still open for the next one.
Mature figs and plane trees around Alexandria Park and Sydney Park push roots into any hairline crack in ageing sewer lines beneath the footpaths.
Relining lets both things be true at once. The garden stays as it is and the drain stops being a route to water. For most owners that is the whole appeal, and it is why no-dig gets specified on established blocks far more often than on new ones.
Shared lines, landlords and who authorises the work
In a strip of tenancies the drainage is frequently shared, which means the fault is often not under the premises reporting it, and the party who pays is not always the party who called.
That is worth settling before the quote rather than after. Camera footage with distances marked from a known access point is what makes the conversation with a landlord or a neighbouring tenant short, because it shows exactly where the defect sits.
Joints, not pipe: what is actually failing
On a clay line the barrel is usually fine. What has gone is the mortar or rubber ring at each joint, and there is one every few hundred millimetres, which is a great many small openings after sixty or eighty years in the ground.
That matters for the quote. You are not replacing a pipe, you are sealing a long series of joints, and a liner does the whole run at once rather than patching them one at a time.
What it costs in Alexandria
Liner, $500–$900 a metre
The prevailing 2026 Sydney range for residential sewer relining.
Single defect patch, $1,500–$4,000
Proportionate for one fault in a sound run. We will recommend it over a full liner when that is what the camera shows.
Full-length reline, $6,000–$15,000
For a run failing along its length, which on old clay is the common finding.
The dig-up alternative, from $2,500 upward
Plus reinstatement. On a bare lawn it can win. Under anything you would miss, it usually does not.
These are market ranges, not our price. Nothing is quoted before the survey, and nothing starts before you agree it. Figures here are indicative of the 2026 Sydney market rather than a quote from us, you get your own number as a fixed price before any work starts.
What Actually Happens
Step 01
Step 01
Look Before Quoting
Nothing is priced until a camera has been down the line. The survey is recorded, distances are marked from a known point, and the footage is yours.
Step 02
Decide What It Needs
A single defect in a sound run wants a patch. A run failing along its length wants a full liner. A collapsed or sagging section wants excavation. The camera decides, not the quote.
Step 03
Install The Liner
Jet clean, install through the existing opening, cure in place. Water is off for part of the day and nothing above the pipe is disturbed.
Step 04
Prove It Is Right
Junctions reinstated, final camera run, and the compliance paperwork where the work is notifiable. You keep both recordings.

Relining, Answered Properly
Straight answers on price, durability and when to dig instead.
It depends on the policy and, more importantly, on the cause. Gradual deterioration and tree root intrusion are commonly excluded, while sudden accidental damage is often covered. That distinction is settled on evidence, which is why dated camera footage showing the defect and its position is worth keeping even if you never claim. It cannot be reconstructed after the repair.
No. A liner takes the shape of the pipe it cures inside, so it cannot correct a run that has sagged into a belly or lost its fall, and it has nothing to line against where a section has collapsed. Badly deformed or crushed pipe needs replacing. What relines well is the common case: a sound barrel with cracked or open joints, which is most older clay drainage.
Relining is priced per metre and the range across Sydney in 2026 is roughly $500 to $900 a metre for a domestic sewer, with junction reinstatement and access usually quoted separately. A short patch repair over a single defect commonly lands between $1,500 and $4,000, and a full-length domestic run more often sits between $6,000 and $15,000. The honest comparison is not liner against nothing: it is liner against excavation plus reinstating whatever sits on top of the pipe.
Clean it and camera it before deciding. Relining a greased line without addressing the grease gives you a smooth new surface to coat and barely changes the interval. Where the camera shows cracks or open joints under the build-up, relining is worth doing and the smoother bore does slow re-accumulation. Where the barrel is sound, a jetting schedule is the cheaper and more honest answer.
It is groundwater and stormwater entering the sewer through cracks and open joints, and it matters more than most people expect. It quietly overloads a line that would otherwise cope, which shows up as a system that backs up in wet weather and behaves perfectly in dry. If that is your pattern, sealing the run is the fix and clearing will never reproduce it.
Clay is close to the ideal host. It is rigid, round and predictable, so the liner cures hard against a barrel that holds its shape. The joints that make clay fail are the same joints a liner seals in one pass. Age alone does not rule a line out: what matters is whether the barrel is sound and the fall is intact.
Yes, along the relined length. Roots do not attack sound pipe, they find a way in through an open joint or crack, and a liner is continuous with no joints for them to exploit. Cutting roots out clears the pipe but leaves the entry point exactly as it was, which is why jetted lines tend to reblock on a predictable interval.
