KJM's Credentials - We have won many awards for Customer Service & Conservatory design

KJM was formed in December 1982, we started life as KJM Replacement Windows Ltd and it was decided that as our range of products grew over the years and included conservatories, that we changed our name. So the company was renamed KJM Group Ltd. Over the years KJM has become a well established and a reputable company, which has gained the trust of thousands of home owners and businesses alike! We have been named as one of the top five UK companies no less than five times. Our diverse range of products gives you the options that you may require. We don't just sell PVCu, but offer timber and aluminium as well. We backed this up with a comprehensive 10 year warranty (insurance backed) that has a proven record. Sales calls are free, without pressure and our pricing is competitive. Give us a try, you wont be disappointed

Reviews of our glazing business

We also were impressed with the "no pressure to pay until fully satisfied" policy you use. We are totally satisfied and therefore have pleasure attaching our cheque

Mr & Mrs W. Durrington

The windows are really excellent, even better than we expected, and we'd really like to thank you for your early and honest advice, a competitive price and no hard sell, and then a very easy and professional installation.  We can completely understand why you guys have such a great reputation.

Mr Ness, Ascot

KJM have been extensively throughout The Winchester Diocese replacing windows/fascias and soffits and installing bespoke conservatories for over 25 years. I am pleased to say that I have never received bad feedback from any clergy and would be happy to recommend KJM to anybody considering replacement window products! From sales to after-care the service is second to none!

Chris Mariner Houses Manager, The Diocese of Winchester


As a result of the excellent service and workmanship with the first set of windows, I returned to KJM Group Ltd for new rear windows and doors. Both sets of work (in December 2012 and July 2013) were completed to the highest standards, according to schedule, on budget and with great attention given to customer satisfaction. As I live on the Isle of Wight, I thought the service was first class, particularly when a return visit was needed to adjust one of the doors. There was no quibble about this and the team was meticulous to ensure that the doors fitted perfectly. This company goes the extra mile plus!
