As opposed to most home improvement firms, we manufacture our own products as well. During our years of experience as fabricators, we have made our own windows, doors, and conservatories. Hence, we have full control over the quality of the products and materials we use in our installations. By doing this we can be sure that only the highest quality materials are used in your installation, protecting the quality of the work.


The products we make are custom-made to your specifications. It means we can offer both modern and heritage color options, so you can choose what you like. As our own fabricator, we are able to offer you a much larger selection of colours including Chartwell Green, Dark Anthracite Grey, Light French Grey, Black, White Wood Grain and Cream.
