Windows
Castle Windows offers a comprehensive range of double-glazed windows, including casement, sash, and aluminium designs. Our energy-efficient solutions enhance home security, reduce noise, and improve thermal performance. Each installation is tailored to match property styles, ensuring durability and aesthetic appeal while meeting modern building standards.
Doors
We provide durable composite, uPVC, and bi-fold doors designed to boost security and curb appeal. Our doors feature advanced locking systems, weatherproofing, and customisable finishes. Expert fitting ensures seamless integration with existing structures, combining functionality with contemporary design for both front and garden access.
Conservatories
Our conservatories create versatile living spaces with glass or solid roofs, available in traditional and modern styles. Tailored to individual needs, they offer year-round usability, enhanced natural light, and thermal efficiency. We handle every stage, from design to installation, ensuring compliance with building regulations and aesthetic harmony with your home.
Roofline
Castle Windows supplies and installs uPVC fascias, soffits, and guttering to protect homes from weather damage. Our Eurocell-sourced products resist warping, fading, and rot, requiring minimal maintenance. The service includes full replacement or repairs, improving both functionality and exterior appearance with a focus on durability and visual cohesion.
Orangeries
Orangeries combine brickwork and glass to create elegant, light-filled extensions. Ideal for dining or relaxation, they feature insulated roofs and high-performance glazing. Our bespoke designs integrate seamlessly with existing architecture, offering a premium alternative to traditional conservatories with enhanced structural solidity and thermal efficiency.
