uPVC Windows
We supply and install A-rated uPVC windows designed to enhance energy efficiency, security, and property value. Available in casement, tilt & turn, and box sash styles, our windows feature multiple colour finishes and glazing options. With over 25 years of experience in Cornwall, all installations come with a 10-year guarantee covering materials and labour.
Aluminium Doors
Our aluminium and composite doors combine modern aesthetics with robust security features. Options include front/back doors, bi-fold, and patio designs tailored to individual preferences. Using Swish products, we ensure precise fitting and energy efficiency, backed by a 10-year guarantee. Installations prioritise seamless integration with existing property architecture.
Conservatories
We design and build bespoke conservatories ranging from traditional lean-to styles to Victorian and Georgian designs. All projects include an insurance-backed guarantee and focus on maximising natural light and usable space. Our team handles every aspect from groundwork to completion, ensuring energy-efficient, year-round usability.
Roof Lanterns
Our UltraSky roof lanterns enhance natural light in living spaces while maintaining thermal efficiency. Available in custom sizes and finishes, these rooflights reduce heat loss and noise pollution. We offer free consultations to ensure designs complement property architecture, with installations suitable for new builds and existing roofs.
Window Repairs
We specialise in reglazing misted or damaged double-glazed units, often upgrading to C, B, or A-rated glass for improved efficiency. Our service avoids unnecessary full-window replacements, focusing on cost-effective repairs. Using Planitherm products, we address coastal corrosion issues specific to Cornwall's climate while maintaining aesthetic integrity.
