Unblocking of drains
"The service was amazing, quick to turn up and the man didn't leave until he had sorted the problem. We would be recommending them to everyone."

The plumbing is not straightforward but he saw the issue and cleared the blockage very quickly without wasting time. He was very thorough and cleaned up afterwards. My sink now drains faster than it has in years and I am very happy. I was told exactly how much it would cost beforehand, so no hidden extras, plus the engineer offered a 28 day call back for free if the issue wasn't resolved. "
