How Much Does a Blocked Drain Cost in Melbourne?

Why Blocked Drain Costs Vary So Much in Melbourne

One plumber quotes $150. Another quotes $600. Same suburb, same symptom — blocked drain. The difference isn’t always skill or quality; it’s usually what’s actually happening inside the pipe and what equipment is needed to fix it properly.

A slow shower drain caused by a hair clog near the surface is a completely different job to a main sewer line blocked by tree roots 15 metres down. The tools, time and expertise required are not the same, and neither is the price.

What You’ll Pay by Blockage Type

Every job gets a fixed price before work starts. Here’s how the common Melbourne blockages compare:

Hydro Jetting vs Electric Eel — Which One Do You Need?

This is the most common question about drain pricing in Melbourne, and it matters because the two methods are priced differently.

🐍 Electric Eel (Drain Snake)

A rotating cable that cuts or pushes through a blockage. Faster to set up and lower cost. For a simple hair or grease clog in a single fixture — shower, basin, kitchen sink — it does the job. But it only opens a path through the blockage; it doesn’t clean the pipe walls. For tree roots, it’s a temporary fix at best.

💦 High-Pressure Hydro Jet

A 5000 PSI water jet that scours the full internal diameter of the pipe clean. It removes root mass, grease, scale and debris from the pipe walls — not just the centre. The results last significantly longer. For main sewer lines, recurring blockages or any job with root intrusion, hydro jetting is the correct tool. A plumber who only offers snaking on a root-blocked sewer line is not fixing your problem.

When Do You Need a CCTV Drain Inspection?

A CCTV drain camera inspection lets your plumber see inside the pipe before and after clearing. It’s not always necessary — but it’s essential in these situations:

• Recurring blockages — cleared more than once in 12 months? The camera shows you why it keeps happening.
• Pre-purchase inspection — reveals cracked, collapsed or root-invaded pipes before you buy. See our pre-purchase guide.
• After a major main-line blockage — confirms the pipe is intact.
• Gurgling or sewer smells — signs of a deeper issue a surface clear won’t fix. Smoke testing finds odour escape points cameras can’t see.
• Insurance claims — insurers accept CCTV footage as evidence of pipe condition and cause of damage.

What it costs with us: every main sewer job ends with a camera run at no extra charge. You see the footage, you know the pipe is clear — or you know exactly what needs fixing before you spend another dollar. Standalone inspections are quoted upfront based on line length and access.

After-Hours & Emergency Costs — The Honest Version

Evening, weekend and public holiday callouts cost more everywhere — the question is whether you find out before or after the work. We tell you the full price on the phone, before attending. A few honest tips:

• If it can safely wait until morning, it will cost less. One blocked fixture that isn’t overflowing can usually wait; sewage coming up through floor wastes cannot.
• Stop using water immediately — it keeps a bad situation from becoming a flooded-floor situation (and a bigger bill).
• Don’t pour chemicals in while you wait. They rarely work, and a drain full of caustic solution is slower and more hazardous to clear — which costs you more.

For genuine emergencies — sewage overflow, every fixture backed up — our emergency blocked drain service runs 24/7 with same-day response across Melbourne’s east.

How to Avoid Getting Overcharged

7 Ways to Keep Drain Costs Down

1. Act at the gurgle stage. A partial blockage is a smaller job than a full overflow — every time.
2. Book business hours when it’s safe to wait.
3. Know where your inspection opening is — easy access saves time on site.
4. Skip the supermarket chemicals — they add hazard, not value.
5. Bundle small jobs — a dripping tap fixed during a drain visit costs less than a separate callout. See general plumbing.
6. Get the camera proof — footage means you never pay twice for the same misdiagnosed problem.
7. Consider maintenance if you’ve had two or more blockages in a year — a scheduled jetting service beats emergency pricing every time.

Blocked Drain Cost FAQs — Melbourne 2026

How much does it cost to unblock a drain in Melbourne in 2026?

Most residential blocked drains in Melbourne cost between $300 and $800, depending on the issue. Simple single-fixture clears sit at the lower end; hydro jetting, tree root cutting and deep main-line work sit toward the top. The best protection is a plumber who gives you a fixed written quote before any work begins — which is exactly what Water Serpent does.

Why is my blocked drain quote higher than I expected?

The main cost drivers are the depth of the blockage in the main sewer line, tree root intrusion requiring hydro jetting instead of snaking, after-hours or weekend timing, and access difficulty to your inspection opening. A simple shower drain is always cheaper than a blocked main sewer line.

Is hydro jetting worth the extra cost?

Yes — especially for recurring blockages or tree root problems. A hydro jet scours the full pipe wall clean, while an electric eel only punches a hole through the blockage. Hydro jetting lasts significantly longer between clears and is the industry standard for main sewer lines in Melbourne’s eastern suburbs.

How much does a CCTV drain inspection cost in Melbourne?

With Water Serpent, the camera run is included at no extra charge on every main sewer clearing job. Standalone CCTV inspections — pre-purchase checks, recurring blockage diagnosis — are quoted upfront based on the length of the line and access, before any work starts.

How much does hydro jetting cost in Melbourne?

More than a basic eel clear, less than paying to clear the same drain three times a year. Most jetting jobs on residential lines still land within the standard $300–$800 range depending on roots and line length — always as a fixed upfront quote, never an hourly open tab.

Do plumbers charge for quotes in Melbourne?

Some do. We don’t — describe the symptoms over the phone and Jack will diagnose the likely cause and give you a fixed price for free, usually in about two minutes on 0425 226 636.

Do I need a CCTV drain inspection?

You need one when drains block repeatedly, when you’re buying a property, or after a major main-line blockage. The camera shows exactly why it’s blocking — roots, cracks, collapsed pipe — so you fix the cause, not just the symptom. Water Serpent runs the camera on every main sewer job at no extra charge.

Are there call-out fees on top of the job price?

Water Serpent Plumbing charges no call-out fee during business hours. After-hours emergency response carries a surcharge, which we tell you upfront before attending. Always ask any plumber about call-out fees before they arrive.

Are blocked drains more expensive to clear in winter?

The job price doesn’t change with the season, but winter exposes problems: partially blocked stormwater and sewer lines that coped in dry weather overflow in the first heavy rain, and demand for emergency slots peaks. Clearing a slow drain in autumn is the cheapest version of that job you’ll ever get.

What is pipe relining and when is it needed?

Pipe relining is a no-dig method of repairing cracked, root-damaged or collapsed pipes from the inside. It’s needed when a CCTV inspection reveals structural damage that clearing alone won’t fix. It carries a 50-year design life and avoids costly excavation of your yard or driveway.

Will my insurance cover a blocked drain?

Standard home insurance usually doesn’t cover gradual blockages, but may cover damage caused by sewage overflow — flooring, walls, carpets. We provide CCTV reports and written quotes that insurers accept as evidence of pipe condition and cause of damage.
