Set up in 1986 by Rob and Julie McKane, due to Rob's background in joinery and real demand for quality yet cost-effective home improvements in the local area, the RJM journey began with the supply of traditional timber windows and doors. Keeping their finger on the pulse of the latest home improvement trends, in 1995 the business scaled-up to larger premises, investing in cutting-edge machinery to make the crucial change from timber to uPVC.
Following further investment in 2004, RJM moved to larger premises and invested in pioneering glass processing machinery. A close-knit team, RJM windows includes three of the McKane's children, with more than half of the staff remaining loyal to the company for 15 years or more.
