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!
