During the 1970's and early 1980's the factory's production output was reaching full capacity producing window sills, along with a new product; fence cappings. This momentum continued for many years with the high demand for solid and simple building products. By late 1980, the market went through a "style change" and as a result, the demand for sills and cappings began to decline. Building techniques were changing, designers were looking for new ways to bring flair and uniqueness into their designs and customers were searching for something fresh. In 1988, the company was purchased by Mavis and Des Nicel focusing on the development and production of coloured glazed bricks.
