Blocked Drain Cost in Brisbane (2026)
Updated 2026-08-14 · Register QBCC
The blocked-drain quotes we record across Greater Brisbane run A$150–450 in 2026 — an observed range from quoted jobs, not a published price list. The 3× spread is not haggling room either; it is severity: a simple clear with rods or a machine sits at the bottom, and the top end buys a CCTV camera inspection plus high-pressure water jetting, which is what tree-root intrusions in older suburbs actually need. Before you pay anyone, though, read the second section — some blockages are the water utility's job to fix, free.
Costs at a glance
Ranges reflect quotes observed locally — not national averages, not advertised "from" prices.
| Service | Typical range (A$) |
|---|---|
Blocked drain — clear (rods/machine) Brisbane blocked-drain clearing, 2026 — simple clears at the low end; the high end includes CCTV camera inspection and high-pressure jet-rodding for the tree-root blockages common in older suburbs. The Brisbane Plumbers' published Brisbane guide — which states its figures are general market ranges rather than that business's own fixed prices, and draws partly on Yellow Pages' national plumbing cost guide — puts a simple clear at $150–400, matching the low end; AC Plumbing (Brisbane), quoting its own service pricing, prices a clear-plus-CCTV package at $400–550+, which sets the top of this range. | A$150 — A$550 |
Call-out + first 30–60 min (standard hours) Brisbane call-out including the first 30–60 min, standard business hours, 2026. Charlie's Plumbing & Gas Solutions (Brisbane) separates its pricing into a $60–120 call-out (attendance) plus a $90–150/hour labour rate; combining the call-out with 30–60 minutes of labour — this line's own scope — computes to roughly $105–270. Salmon Plumbing (Brisbane, QBCC 741050) publishes a $175–295 business-hours call-out fee that sits within that computed band, though its page doesn't clarify whether that figure already includes some work time, so it can't be cleanly reconciled to this exact scope either way. | A$105 — A$270 |
First: is it even your pipe?
The split is simple: pipes on your property up to the connection point are yours to fix; the sewer mains beyond it belong to Urban Utilities. The practical test costs nothing — ask a neighbour. If drains on both properties are backing up at once, the blockage is almost certainly in the main, and Urban Utilities attends mains faults at no charge. Call 13 23 64 (24 hours) before you book a private plumber.
If only your place is affected, it is your drain, and a licensed plumber is the right call. Booking one first and discovering the fault was in the main is an expensive way to learn the order of operations.
Why quotes span $150 to $450
A straightforward clear — a machine auger through an accessible blockage — is the low end of the range and often done within the call-out hour. The price climbs with two additions: a CCTV camera to find what and where the blockage actually is, and high-pressure jetting to cut through it properly.
In Brisbane's older suburbs the culprit is usually tree roots in aging earthenware pipes, and there the camera-plus-jetter combination is not upselling — an auger punches a hole through the root mass that regrows within months. If a plumber recommends CCTV, asking to see the footage is both normal and useful: it shows you the pipe's real condition and gives you evidence for any future decision.
Storm season matters too. From November to April, heavy rain overloads stormwater systems in low-lying suburbs, and what looks like a blockage may be the network at capacity. If it only happens during downpours, say so when you book — it changes the diagnosis.
Tree roots keep coming back — your real options
Cutting roots out restores flow but does not close the crack they entered through, so regrowth is a when, not an if. The durable fixes are relining the pipe from the inside or excavating and replacing the damaged section. Both cost multiples of a clear and depend entirely on what the CCTV shows, which is why the footage from this job becomes the quote basis for the next decision.
A reasonable pattern for Brisbane's older housing stock: pay for the proper clear now, keep the CCTV footage, and get relining quotes from two or three licensed drainers before the next blockage forces the decision at emergency prices.
Common questions
How do I know if it's my drain or the sewer main?
Check whether neighbours are affected. Multiple properties backing up at once points to the main — Urban Utilities' responsibility, attended free, 13 23 64, 24 hours. Only your property affected means it is your drain and your licensed plumber.
Is a CCTV inspection worth paying for, or an upsell?
For a first-time, simple blockage — often unnecessary. For anything recurring, slow-building, or in an older suburb, it is the difference between treating symptoms and knowing the cause. Ask to see the footage; a plumber confident in the diagnosis will show you.
Should I try a chemical drain cleaner first?
On a slow kitchen sink, maybe. On a sewer-line blockage, no — caustic cleaners will not touch tree roots or a main-line obstruction, they make the water sitting in the pipe hazardous for whoever opens it next, and some plumbers charge extra to work on chemically-dosed drains.
