Early engagement with us on large scale projects is a key element for success

Since our first forays into the Data Centre/ICT sector in the early 1980s, John Sisk & Son has had a continued, proven track record in delivering high-end, mission critical projects for domestic and multinational micro-electronics, data and ICT clients across Ireland and the UK.

Our commitment to delivering excellence and innovation has led us to a business model that is built on strong, long-lasting relationships where 70 per cent of our business stems from existing clients.
