Why drain unblocking matters

Blocked drains can cause:

  • Slow drainage and backups
  • Property damage and flooding
  • Health and safety hazards
  • Operational disruption for businesses

Prompt unblocking reduces the risk of major problems, protects property, and ensures drainage systems continue to function reliably.

Our approach

Shanahan Contracting Ltd combines modern equipment with experienced staff to provide a thorough, safe, and environmentally responsible service:

  • Assessment – Inspect the drainage system to locate the blockage
  • Clearing – High-pressure jetting removes grease, fat, silt, debris, and other obstructions
  • Verification – Test flow to confirm drains are fully cleared
  • Advice – Provide guidance on maintenance, cleaning schedules, and preventing future blockages

This structured approach ensures the job is done efficiently, with minimal disruption.
