If you are dealing with a Blocked Drain Melbourne homeowners often ask the same question before anything else: how much is this actually going to cost? It is a fair question, and it is also one that is hard to answer honestly with a single number, because a blocked drain cost can range from a simple call-out fee to several thousand dollars depending on what is actually wrong with the pipe. This guide breaks down where your job is likely to land, what pushes the price up, and why two blocked drains that look identical from the surface can end up costing very different amounts.
The Short Answer
Across Australia, a straightforward drain clearing job for a single fixture, a sink, shower, toilet, or basin, generally falls somewhere in the low hundreds of dollars. Once the job involves a main sewer line, hydro jetting, a CCTV inspection, tree root removal, or pipe repair, the price climbs considerably higher, often into the high hundreds or beyond. These are general market ranges rather than a fixed quote, since the only way to know your exact price is for a licensed plumber to actually look at the blockage. King and Sons Plumbing provides upfront, job-based pricing before any work starts, so you always know the cost before you commit, rather than being charged by the hour.
What Does a Plumber Charge to Clear a Blocked Drain?
For a basic, single-fixture blockage, most Melbourne plumbers charge somewhere in the low-to-mid hundreds of dollars. This typically covers a straightforward mechanical clear using a drain auger or electric eel to physically break up and remove whatever is blocking the pipe. It suits everyday issues like a slow kitchen sink, a blocked shower drain, or a toilet that will not flush properly.
Where the job sits within that range usually comes down to access. A trap under a vanity is quick and cheap to reach. A blockage further down the line, or one that needs to be accessed through an outdoor gully or overflow point, takes longer and costs more, even if the underlying clog is not especially severe.
Is There Usually a Call-Out Fee?
Most plumbing companies do charge some form of call-out or minimum service fee, and it is worth asking about this upfront rather than being surprised by it on the invoice. King and Sons Plumbing operates on a $0 call-out fee basis, waived when you proceed with the job, so you are not paying extra just to have a plumber assess the problem. We also charge per job rather than by the hour, which means an unexpectedly stubborn blockage will not blow out your bill simply because it took longer than planned.
How Much Does Hydro Jetting Cost?
Hydro jetting, sometimes called high-pressure water jetting, uses a powerful stream of water to strip grease, scale, root intrusion, and built-up debris from the full internal surface of the pipe, rather than just punching a hole through the middle of the blockage. Because it does a more thorough job and requires specialised equipment, hydro jetting generally costs more than a basic clear, often landing in the mid hundreds to high hundreds of dollars depending on the length and condition of the pipe being treated. It is frequently the better long-term option for recurring blockages, since a standard auger clear can leave grease or root material coating the pipe walls, ready to build up again within weeks.
How Much Does a CCTV Drain Inspection Add?
A CCTV drain inspection feeds a waterproof camera through the pipe to show its exact internal condition, cracks, root intrusion, misalignment, corrosion, or a sagging section, all visible on screen in real time. Booked as a standalone service, this typically adds a moderate cost on top of any clearing work, though many plumbers, including King and Sons, will factor it into a combined job when a blockage looks like it may be structural rather than a simple clog. Given that it removes all the guesswork around what is actually wrong with the pipe, it is one of the more cost-effective steps you can take, particularly if the same drain has blocked more than once.
Does Removing Tree Roots Cost More?
Yes. Tree root removal generally sits above a standard clear, since it usually requires either mechanical root cutting equipment or hydro jetting strong enough to strip root growth from the pipe walls, often followed by a CCTV inspection to check exactly where the roots are entering the line. If roots have caused a crack or gap in the pipe rather than simply growing through an existing joint, ongoing repair or relining may also be needed, which adds further to the cost. Root-related jobs are one of the main reasons a blocked drain cost can end up considerably higher than expected.
How Much Does an Emergency Blocked Drain Call-Out Cost?
After-hours and emergency call-outs, evenings, weekends, and public holidays, typically carry a premium above standard daytime rates, generally adding a few hundred dollars depending on the time and provider. King and Sons Plumbing operates 24 hours a day, 7 days a week, with upfront pricing communicated before we start, so even an urgent overnight call-out comes with a clear cost rather than an unpleasant surprise afterward.
Why Can One Blocked Drain Job Cost Much More Than Another?
Two blocked drains that look the same from the surface, water not draining, a bad smell, gurgling pipes, can have completely different underlying causes, and the cost follows the cause rather than the symptom. A soft clog cleared with a basic auger might cost a few hundred dollars. A collapsed pipe section requiring excavation and replacement can run into the thousands. The main factors that push a job from the lower end of the range to the higher end include:
- How far into the pipe the blockage sits, and how it needs to be accessed
- Whether the cause is a soft clog or a structural fault like a crack, root intrusion, or misalignment
- Whether hydro jetting or a CCTV inspection is needed to properly clear or diagnose the pipe
- Whether the job is during business hours or requires an after-hours emergency response
- Whether the pipe needs repair or relining rather than just clearing
Is Pipe Repair Included in Drain-Clearing Costs?
No, and this is one of the most common points of confusion. Clearing a drain and repairing a drain are two separate services. A clearing job removes whatever is blocking the pipe and gets water flowing again. A repair addresses a fault in the pipe itself, a crack, a collapsed section, a bad joint, or an incorrect grade, and is priced separately because it is a different scope of work entirely. If a plumber clears your drain and mentions signs of a structural issue, that repair will be quoted on top of the clearing cost, not included in it.
When Does Pipe Relining Become More Economical Than Repeated Clearing?
If a drain keeps blocking in the same spot every few months, the cost of repeated clearing adds up fast, and it rarely stays cheaper than fixing the actual problem for long. Pipe relining, a no-dig process that forms a new, smooth pipe inside the damaged one, carries a higher upfront cost than a single clearing job, but it resolves the root cause in most cases involving cracks, root intrusion at a joint, or degraded older pipe material. Once you have paid for three or four repeat call-outs on the same blockage, relining has often already paid for itself compared to the alternative of continuing to clear the same pipe indefinitely.
Get an Accurate Price for Your Blocked Drain
