Get a Quote →Kitchen sinks, bathroom basins, showers and baths. Usually cleared in a single visit. We find the cause so it doesn't keep coming back.
Get a Quote →A camera goes into the pipe and we see exactly what's there. Saves guesswork, saves digging, saves money. Full written report provided.

George Michaelides started Drain Unblocking 247 with a simple idea: be the drainage company that actually shows up, does the job properly, and charges a fair price. That was over 10 years ago. Nothing much has changed.

"George was friendly on the phone and arranged the booking without a long wait. Russell was very thorough, professional and worked quickly. Really pleased there was no call-out charge and pleased with the final quote. Would definitely recommend and use the company again."
Lisa · Trustatrader · April 2026
"Great communication from head office. Attended within a few hours to clear a blockage in a rented flat. Polite engineer and the job was checked thoroughly once complete. Would use this firm again and would highly recommend the service and competitive rates."
Tim · Trustatrader · March 2026
"Arrived on time, was clear on prices, explained what he would do and showed me the end results. We had slow draining in our kitchen and they came out super quick and resolved it. Sometimes you need expert help and I'm glad I called them."
