At a Glance
Brisbane's year-round growing season and heavy wet-season rainfall make both root intrusion and stormwater overload more frequent than in cooler climates. Drain clearing costs $100–$700 per job, with simple internal blockages at the low end and jetting at the top.
What's Included in the Price
The job covers attendance, diagnosis, clearing the blockage using an electric eel, drain rods, or high-pressure water jetter, and a flow test. All drainage work must comply with AS/NZS 3500 Plumbing and Drainage. CCTV camera inspection is a separate line item, recommended for recurring blockages or when root intrusion is suspected. Pipe repairs, relining, or excavation are quoted separately. The base price includes the callout fee. Reinstatement of any landscaping or concrete disturbed during access is not typically included.
What Affects the Cost
- Clearing method. Rod clearing for simple blockages. High-pressure jetting for roots, grease, or debris in longer runs. CCTV for investigation.
- Blockage cause. Grease and hair clear quickly. Tree roots and soil intrusion require more time and power.
- Stormwater vs sewer. Stormwater drains handle higher volumes and are often longer runs with more debris accumulation.
- Wet season impact. Heavy summer rainfall can overwhelm partially blocked stormwater drains, turning minor issues into urgent problems.
- Root growth rate. Brisbane's subtropical climate means roots grow year-round, so cleared pipes re-block faster than in cooler cities.
- Access point location. Some older Brisbane properties have inspection openings buried under decks, gardens, or extensions.
A grease blockage in a kitchen drain cleared with an electric eel in a newer North Lakes property sits toward $100. Recurring root intrusion from a camphor laurel in a 1960s Ashgrove sewer line, requiring extended jetting and CCTV investigation, pushes toward $700.
Blocked drains often become urgent during Brisbane's wet season when stormwater systems are already under load. 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 stormwater is flooding, call immediately.
Brisbane-Specific Considerations
Brisbane's subtropical climate supports year-round root growth, which is the primary driver of sewer blockages in established suburbs. Unlike Melbourne or Adelaide where root activity slows in winter, Brisbane's roots grow 12 months a year. Mango trees, fig species, poinciana, and camphor laurel, all common in suburbs like Ashgrove, Bardon, Taringa, and Coorparoo, have particularly invasive root systems. If you have cleared roots once, expect re-blockage within 12 months unless the pipe is repaired or relined.
Brisbane's wet season (November to March) brings intense storms that dump large volumes of water in short bursts. Stormwater drains that are partially blocked by silt, leaves, or root intrusion cannot handle the flow, leading to backyard flooding and pooling. Keeping stormwater grates clear and scheduling a pre-wet-season inspection helps avoid emergency callouts during storms.
Report main sewer blockages to Queensland Urban Utilities on 13 23 64. Main sewer issues are indicated by multiple properties being affected or overflow at the QUU maintenance hole. QUU attends main sewer blockages at no charge. Your private sewer connection between the property and the main is your responsibility.
Hiring a Licensed Plumber in QLD
All drain clearing work in Queensland must be carried out by a QBCC-licenced plumber. Verify licences through the QBCC (Queensland Building and Construction Commission). For notifiable drainage work (repairs, relining, new connections), the plumber must issue a Form 4 Compliance Certificate. Ask for their QBCC licence number, confirm public liability insurance, and get a written quote that specifies the clearing method and whether CCTV is included or additional.
How We Calculate
Estimates are based on current licenced plumber rates in the Brisbane metropolitan area, adjusted for typical property age and drainage conditions in QLD. All figures include GST. Prices cover standard residential drain clearing. Commercial, body corporate, or council stormwater issues may fall outside these ranges.
