What Affects Blocked Drains Cost?

  • Type of blocked drain service: The biggest cost driver is the service needed. A standard unblock is $220 AUD per visit, CCTV inspect and clear is $550 AUD per visit, and hydrojet drain cleaning is $600 AUD per visit during business hours.
  • Time of attendance: Jobs booked after hours or on weekends cost more because the calculator applies a 1.5 multiplier. That means the same drain clearing job will cost more than a business-hours visit.
  • Access to the drain: If there is no inspection opening or access is tight, pricing increases with a 1.35 multiplier. Harder access can make blocked sewer or branch line work slower and more difficult to complete.
  • Number of visits: This calculator is based on the number of visits, so total cost rises with each attendance. If a recurring blockage needs return visits for further drain unblocking or inspection, the overall price increases accordingly.
