Wooden Sash Windows
Our wooden sash windows combine timeless elegance with modern performance. Crafted from durable Red Grandis timber, they enhance thermal efficiency and security while preserving traditional aesthetics. Ideal for period properties and conservation areas, these windows reduce noise and energy bills. Each unit is custom-made to match your property's architectural style, ensuring lasting value and compliance with heritage regulations.
Double Glazed Sash Windows
Double-glazed sash windows improve insulation and comfort without compromising classic design. Featuring advanced glazing technology, they minimise heat loss, condensation, and external noise. Our units meet Part L Building Regulations, offering enhanced security through multi-point locking systems. Perfect for listed buildings requiring discreet upgrades, these windows maintain visual appeal while delivering modern performance benefits.
Sash Window Repair
We restore sash windows to full functionality, addressing draughts, rot, and mechanical issues. Our repairs preserve original timber where possible, replacing damaged components with precision. Services include cord replacement, frame refurbishment, and draught sealing. This extends window lifespan, improves energy efficiency, and maintains property value, particularly for heritage-listed buildings requiring sympathetic maintenance.
Heritage Sash Windows
Specialist heritage sash windows replicate historic designs for listed properties. Using traditional joinery techniques and materials like Accoya wood, we ensure compliance with conservation area requirements. These windows retain authentic detailing while incorporating modern upgrades such as double glazing. Our solutions balance historical accuracy with improved thermal performance and security for protected buildings.
Bespoke Timber Windows
Custom timber windows are tailored to unique architectural specifications. Available in flush casement, Georgian, and Victorian styles, they integrate with both traditional and contemporary homes. We match existing designs exactly, using sustainably sourced hardwoods for durability. Each window includes weatherproofing features and optional decorative glazing bars, combining aesthetic flexibility with functional improvements.
