I would also never use this company again.
Day 1 they turned up with a hangover and did little apart from criticise the other tradies and damage the house with unrequired trenchs despite being given a clear list of tasks. Day 2 they rushed the job and left it in a very poor state. Filled in trenchs using their fingers, dishwasher leaked, then they dropped nails, screws and concrete all over lawn.
Very poor quality and not cheap.
