From modest beginnings, our company has developed into one of the major joinery and construction firms in the North West employing approximately 100 people.

Over the years we have gained distinction through our involvement in numerous prestigious projects & developments. We specialise in commercial & industrial construction works as well as instigating & managing many housing developments across Ireland . Our large and innovative joinery workshop produces high-class joinery products which are shipped worldwide, accompanied by world-class tradesmen if required. No matter how large or small the contract the O'Neil enthusiasm remains the same. Renowned for efficiency and reliability it is quality that sets us apart.
