Open yellow pages under double glazing installers in your area, ask them to call and give you a quote.Take 3 estimates, pick the one you feel your happy with and get on with it! Not a difficult job-takes 1/2 hour(fitting) that includes having a brew and a chat! select either a feature panel-or just plane panel-usually best to replace with exsisting style. Pay on completion.
