Sash Window Restoration
Our sash window restoration service combines traditional craftsmanship with modern technology to preserve historical integrity while improving functionality. Using our patented VPSS system, we eliminate draughts and rattles, ensuring energy efficiency without compromising aesthetic authenticity. Each restoration includes meticulous attention to detail, from repairing rotten timber to installing discreet secondary glazing, tailored to meet the unique needs of heritage properties.
Casement Windows
We specialise in crafting and restoring casement windows that match original architectural styles while incorporating modern performance features. Our bespoke joinery ensures seamless integration with period properties, using sustainably sourced hardwoods and traditional techniques. From draught-proofing to complete replacements, our solutions enhance thermal efficiency and security while maintaining historical accuracy for residential and commercial buildings.
Secondary Glazing
Our secondary glazing systems provide an unobtrusive solution to improve thermal efficiency and reduce noise pollution in heritage properties. Designed to complement existing windows, these systems maintain visual authenticity while delivering modern comfort. Installation is tailored to each property, ensuring minimal disruption and maximum performance for listed buildings and conservation areas.
Timber Door Restoration
We restore heritage timber doors to their original splendour, addressing issues like rot, draughts, and structural wear. Our techniques preserve authentic features while enhancing security and insulation. Using traditional joinery methods and high-quality materials, we ensure doors remain functional and aesthetically consistent with the property's historical character, backed by our 10-year guarantee.
VPSS Draught Proofing
The Ventrolla North London Perimeter Sealing System (VPSS) is an award-winning solution that eliminates draughts and improves energy efficiency in heritage windows.
