What a blocked drain costs on the Mornington Peninsula
Updated October 2026
Prices below are typical 2026 ranges for the Mornington Peninsula and greater Melbourne. Every job is different, so treat these as a guide and get a fixed price before work starts. A licensed plumber should always quote before clearing.
Quick price guide
- Standard blocked drain clear (plunger, auger or small jet): $150 to $400, with most jobs landing around $280
- CCTV drain camera inspection: $249 to $600
- CCTV inspection plus jet blasting: $350 to $900
- Tree root clearing: $250 to $600
- Pipe relining after root damage or collapse: $3,000 to $8,000 and up, depending on length
What moves the price
The three things that change a drain bill are access, cause and damage. A blocked toilet with an obvious cause at the S-bend is the cheap end. A sewer line blocked by tree roots 20 metres from the house, under a driveway, is the expensive end. On the Peninsula, steep blocks at Mount Martha, McCrae and Arthurs Seat, long driveways on rural properties around Red Hill and Main Ridge, and tight access down the side of a 1960s beach house all add time. Travel distance counts too: a plumber based around Mornington or Somerville has a long run down to Portsea or out to Flinders, and some quotes carry an allowance for it. After-hours and emergency call-outs cost more than a booked weekday visit, so if the drain is slow but still draining, booking ahead saves money.
The holiday-house factor
Peak periods change the maths. Over summer, Easter and long weekends the Peninsula population swells, every plumber is busy, and the cheapest booking slot is the one you took in advance. If you own a holiday house, the practical move is a camera inspection in the quiet months rather than an emergency clear in January. Owners who let their place out short term have more reason again, because a blocked drain on a changeover day costs you the booking as well as the plumber.
Why plumbers quote after a camera
If a drain keeps blocking, clearing it again without finding the cause wastes your money. A CCTV camera run through the line shows exactly what is happening: roots at a joint, a bellied section holding water, or a cracked pipe. That is why many plumbers bundle the camera and the jet blast together. You pay a little more once, instead of paying for the same clear every six months.
When relining is worth it
Relining makes sense when the camera shows a broken or root-infested pipe but the line is otherwise sound. It costs thousands, not hundreds, but it is still usually cheaper than digging up a driveway, a paved courtyard or an established coastal garden to replace the pipe. A good plumber will show you the camera footage and let the pipe make the argument.
Frequently asked questions
Is a free quote really free?
The quote itself is free. Some plumbers charge a call-out fee for a site visit, so ask when they call.
Does insurance cover a blocked drain?
Usually not for the blockage itself. Home insurance sometimes covers damage the blockage caused, such as water damage inside the house. Check your policy before claiming.
Who pays if the blockage is in the main?
South East Water owns and maintains the sewer mains across the Mornington Peninsula. If the blockage turns out to be in their infrastructure rather than your private drainage, report it to them and they clear it at no cost to you. Your plumber can tell you which side of the connection the problem sits.
What if my property is on a septic system?
Plenty of rural and coastal properties on the Peninsula are not connected to reticulated sewer. A plumber still clears the drains between the house and the tank, but the tank itself is pumped out by a liquid waste contractor, and that is a separate cost. Mornington Peninsula Shire regulates on-site wastewater systems, so a failing septic is worth sorting properly rather than patching.
Do I need a compliance certificate?
For plumbing work valued over $750 in Victoria, the licensed plumber issues you a compliance certificate when the job is done. A straightforward drain clear often sits under that threshold, but repair work such as relining usually does not. Ask the plumber at quote stage.
