What affects the cost?
Drain unblocking cost depends on blockage severity, access, whether rodding or high-pressure jetting is needed, and whether diagnosis with a CCTV survey is required. Emergency attendance adds a separate call-out premium.
- Blockage location and severity
- Rodding or high-pressure jetting
- Scheduled or emergency call-out
