Built on strong foundations
Founded by Conor Kearney in 1998, CJK began as a small contractor with a commitment to quality, reliability and long-term client relationships. Those principles continue to shape the business today.
Why CJK
CJK is a mechanical and electrical contractor delivering complex projects across Ireland and internationally. Built through long-term relationships, repeat business and a reputation earned over time, the business has grown steadily by doing good work, standing over what we deliver and investing in the people behind it.
Our story
Built through relationships. Grown through delivery.
Expanding capability
As the business grew, we strengthened our integrated M&E capability, expanded into new sectors and international markets, and invested in our people, systems and standards. We now support clients across an increasingly diverse range of projects and live operational environments.
Trusted to deliver
Today, CJK operates across Ireland and internationally, delivering M&E solutions for leading organisations across the data centre, pharma & life sciences, aviation, energy, commercial and public sectors.
Leadership
CJK is led by an experienced senior team with deep sector knowledge and a hands-on approach to delivery. Across the business, senior leaders remain closely connected to projects, clients and teams, helping maintain the standards, relationships and culture that have shaped CJK since it was founded.
