Combining strength and style, composite doors are hard-wearing and visually attractive - an excellent choice for any home. Available in a selection of styles and colours, they will protect and enhance any type of property. The composite doors that we install are courtesy of Door Stop International, which are renowned within the industry for their excellent performance levels. In addition, our composite doors are also highly secure - boasting multi-point locking systems, and GRP (Glass Reinforced Plastic) combined with a solid foam core to provide ultimate security.
