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.

• Today believe it or not I had the privilege of having my sceptic tank emptied by a Clive from Shanahan’s Strange as it may sound as it’s not a procedure I warm to but in this case it was a necessity! Firstly initial contact with the company who immediately recognised my dilemma and gave me the next available appointment at 7.30am the next day Then on time came CLIVE huge tanker and all, down our narrow drive. Twice he had to reverse some 60 yard to let neighbours get to work and an to an emergency dental appointment Once set up he emptied the tank only to find the soil pipe was blocked, to cut a long story short he sucked, blew, sucked again and eventually power jetted the blockage away (mechanically) that is staying nearly an hour in the process In this day and age people are quick to moan and complain and seldom, give praise but rest assured in Clive you have a real gem. Nothing is too much trouble. Amazon always ask How was your delivery? How many stars, was it on time, respect of property etc etc, but NEVER have I ticked the above and beyond but with Clive that box if there was such a box I would tick it. Well done and a big thank you to Clive
