From a young age Justin could be found in his dads shed taking things apart and rebuilding them, not always successfully ! This was the start of a life long passion for fixing things and finding out how they work. His Dad had worked on canal boats in his younger days before moving in to the motor trade as a mechanic and Justin started his working life following his Dad in to the motor trade before moving on to boats. He moved into the marine market after seeing a need for a skilled engineer, 15 years of seeing how boats are built and repaired gave a good grounding in to becoming a surveyor.
