At a Glance
Melbourne's mature elms, plane trees, and ageing clay pipe network make root-related blockages especially common across the inner and middle suburbs. Drain clearing costs $100–$750 per job, from basic rod clearing at the low end to high-pressure jetting for root intrusion.
What's Included in the Price
The job includes attendance, locating and diagnosing the blockage, clearing it with an electric eel, drain rods, or high-pressure jetter, and a flow test to confirm drainage is restored. All drainage work must comply with AS/NZS 3500 Plumbing and Drainage. CCTV camera inspection is a separate service, typically recommended when blockages recur or when root intrusion is suspected. Pipe repairs, patch relining, or full excavation and replacement are quoted separately if the camera reveals structural damage. The callout fee is built into the base quote.
What Affects the Cost
- Clearing method. Electric eel or rods for simple blockages. High-pressure jetting for roots or grease buildup. CCTV adds a diagnostic layer.
- Pipe material and age. Pre-1970 clay (earthenware) pipes have joints every 600mm where roots enter. PVC pipes have fewer and tighter joints.
- Tree root severity. Light root infiltration clears quickly. Dense root masses filling the pipe require extended jetting time.
- Blockage location. An internal trap blockage is quick. A blockage 20 metres down the sewer line in the front yard takes longer.
- Access point condition. Clear, accessible inspection openings speed the job. Buried or damaged access points need to be exposed first.
- Recurrence pattern. A first-time blockage is usually straightforward. Repeat blockages indicate pipe damage requiring investigation.
A hair blockage in a shower drain cleared with an electric eel in a 2005 Craigieburn home sits toward $100. Recurring root intrusion in a 25-metre clay sewer line under mature elms in Hawthorn, requiring high-pressure jetting and CCTV investigation, pushes toward $750.
Blocked drains can escalate quickly when sewage backs up into floor wastes or showers. After-hours, weekend, and public holiday callouts carry premium rates. If only one drain is slow and there is no sewage overflow, scheduling during business hours saves money. If sewage is backing up or multiple fixtures are affected, call immediately.
Melbourne-Specific Considerations
Melbourne's inner and middle suburbs are lined with mature elms, plane trees, and liquid ambers. These deciduous trees have extensive root systems that aggressively target sewer pipe joints for moisture. Suburbs like Kew, Hawthorn, Brunswick, and Northcote have particularly high rates of root intrusion due to the combination of large street trees and pre-1970 clay pipe drainage.
Clay (earthenware) pipes were standard in Melbourne until the mid-1970s. These pipes use rubber ring or cement mortar joints every 600mm. Over 50+ years the joints deteriorate, creating entry points for roots. If your property was built before 1975 and you are experiencing recurring blockages, a CCTV inspection will often reveal multiple joint infiltrations. Pipe relining, inserting a resin sleeve inside the existing pipe, is the most common long-term fix. It avoids the need to excavate the entire run.
Melbourne has three water retailers. Report main sewer blockages to Yarra Valley Water on 13 27 62 (north and east), South East Water on 132 812 (south-east), or Greater Western Water on 13 44 99 (CBD, inner, and western suburbs). Main sewer issues are identified by multiple properties being affected or overflow at the manhole. Private sewer connections between your property and the main are the property owner's responsibility.
Hiring a Licensed Plumber in VIC
All drain clearing work in Victoria must be performed by a plumber registered with the Victorian Building Authority (VBA). Plumbers must issue a Compliance Certificate for notifiable plumbing work, which includes new or altered drainage. Ask for their VBA registration number, confirm public liability insurance, and get a written quote with scope clearly defined before work starts.
How We Calculate
Estimates are based on current licenced plumber rates in the Melbourne metropolitan area, adjusted for typical property age and drainage infrastructure in VIC. All figures include GST. Prices cover standard residential drain clearing. Commercial, body corporate, or main sewer blockages fall outside these ranges.
