About Us

The name MacNamee has been associated with specialist cleaning and water-jetting since its founding in the 1970's. It was one of the early pioneers of what has become one of the main cleaning methods of today.

In 1993, the company was acquired by J. & J. Denholm, an established shipping and industrial services organisation who were diversifying into other maritime activities, including painting and coating for the North Sea oil and gas industry.
