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.

• I just wanted to say what a fantastic service we had yesterday. The gentleman that came to empty the tank negotiated the well and narrow driveway brilliantly!

  And the drain survey team were equally fantastic! Courteous and really helpful; involving us (we were both very curious!) as much as we wanted!

  What a brilliant team to have come to our property! We will most certainly be coming back to you for any future needs.

  Thank you.
