Errigal Contracts

Its headquarters in Monaghan has a dedicated manufacturing facility, with regional offices in London, Derry, Zurich, Amsterdam and, more recently, Frankfurt. The company has carved a niche in the construction market in Ireland, the UK, and mainland Europe as a specialist contractor in partition systems, external façades, interior fit-outs, ceilings, and bespoke solutions. Errigal is internationally respected for its unique ability to provide specialist fit-out and cladding services on construction projects of all types, sizes and locations.


Errigal has a £20m off-site manufacturing base at the 70-acre former Enkalon industrial estate in Co Antrim. Ongoing development at the site and targeted growth in off-site assembly will enable the contractor to take the opportunity to grow with its clients and achieve an annual turnover of more than £300m over the next five years. Damien Treanor has over 30 years of experience in the construction industry in the UK, Ireland and internationally. Treanor is dedicated to people, community and industry development and is the driving force behind ‘The Errigal Way’. This ethos is reflected in the team at Errigal, who are committed to doing their very best, however big or small the challenge might be. Cormac McCloskey is widely known as the operational powerhouse of Errigal. He has steered many of the company’s successful projects with a can-do approach while building trusted long-term partnerships.
