Traditional and Modern Styles Available

Over the years, we have come to realise that even new build designs tend to favour traditional window styles. To complement this, we use a specialist window system which can replicate the features of traditional joinery and sculptured sashes. To complete the authentic look we also use matching beading. However, in some cases, a clean, modern style is favoured, making chamfered sashes the perfect choice.
