Services
Sash Window Restoration
Our sash window restoration service combines traditional craftsmanship with modern technology to preserve historical integrity while improving functionality. We address common issues like draughts, rot, and operational difficulties using our patented VPSS draught-proofing system and SRS glazing upgrade. Each restoration includes meticulous timber repair, ironmongery replacement, and optional secondary glazing to enhance thermal efficiency without altering original aesthetics. This service is ideal for Grade II listed properties and conservation areas requiring specialist attention.
Casement Window Restoration
Specialising in casement window restoration, we employ traditional joinery techniques alongside innovative solutions to revive period features. Our process includes draught-proofing with VPSS technology, replacing decayed components with sustainably sourced timber, and upgrading hardware for improved security. We maintain original profiles while integrating modern performance enhancements like double glazing options. This service caters to both residential and commercial properties seeking to retain historical character while meeting contemporary efficiency standards.
Timber Door Restoration
Our timber door restoration service preserves authentic character through painstaking repair techniques combined with security upgrades. We address issues like warping, rot, and draughts using traditional carpentry methods and VR90 wood repair systems. The process includes draught-proofing, ironmongery replacement, and optional double-glazing integration while maintaining original design elements. This service ensures period doors retain their historical value while achieving modern thermal and security performance levels.
VPSS Draught Proofing
The Ventrolla Perimeter Sealing System (VPSS) is an award-winning draught-proofing solution that eliminates draughts without altering window appearance. This discreet system reduces heat loss by 15-20% through precision-engineered seals fitted around sash edges. It maintains original window operation while improving energy efficiency and noise reduction. VPSS is suitable for both sash and casement windows, offering a conservation-approved alternative to replacement that preserves historical integrity while meeting modern performance standards.
Planning Advisory Service
Our dedicated planning advisory service supports projects involving listed buildings and conservation areas. We provide expert guidance through approval processes, preparing detailed specifications and CAD drawings for planning submissions. Our team collaborates with English Heritage, Historic Scotland, and local authorities to ensure compliance with heritage regulations. This service includes condition assessments, material recommendations, and project-specific documentation to streamline approvals while maintaining historical accuracy throughout restoration works.
