KJM was formed in 1982, taking its name from the three founding directors Ken Hammant, John Creasey and Mick Burrell. Originally manufacturing our own windows on West Portway Industrial Estate in Andover, the company concentrated on uPVC windows as we were unable to manufacture anything else. In these early years, KJM won some substantial commercial contracts - the most notable being from Winchester City Council for whom we manufactured and installed hundreds of windows. Many streets in Winchester still have KJM windows to this day. Over time the economics of manufacturing on a relatively small scale proved not to be cost effective and, with many new materials becoming available, and customer trends requiring a more diverse range of products, we ceased manufacturing in 1996. This move enabled KJM to offer a much larger product portfolio. Today we can offer a huge range of windows, doors and conservatories in uPVC, aluminium and hardwood. KJM's largest supplier manufactures from their base in Wellingborough (near Northampton) and produce high quality windows to the company's own specification. They are a quality supplier and have won many awards for their products and services. We, understand the principle that people may require a quotation to find out a cost and not be bullied in to making a purchase. None of KJM’s sales team is commission based. Customer service is paramount to KJM as we rely on most of our business coming through recommendation. No one can promise that every job will run absolutely perfectly - even the best has the odd hitch on rare occasions, but we can assure you that we strive for complete customer satisfaction. The consequence of our efforts is that more than 80% of our work comes through recommendation or existing customers returning to us again
