The company was formed by Ernie Moorhouse during 1978 after he had gained more than twenty years valuable experience at a senior level with a national contractor.   The company began with a labour force of ten operatives working from a small office, progressing to larger premises and workshops by 1985. The present office, with substantial workshops and storage was purpose built by the company to cater for longer term expansion plans. This facility is sufficient to take us on to a turnover of £15m.

Sexton used cmx's original parent company in the early eighties but the Pegasus software that was being used at the time was being phased out and replace by newer Opera software which was not going to be part of the portfolio. This meant Sexton finding another dealer for a while before moving to a third source and Sage. The wheel turned full circle as cmx were called in to sort out some problems on the systems and update some computers. The existing computers were supplemented by a server for email and broadband and a more powerful CAD computer.
