Services
Sash window renovation
Our sash window renovation service revitalises period windows through comprehensive assessment, structural repairs, and draught-proofing installations. We preserve original timber elements while enhancing functionality, ensuring smooth operation and improved thermal efficiency. Each project follows a systematic process including box frame restoration, sash rebalancing, and traditional paint preparation, maintaining historical accuracy for conservation areas.
Double glazing solution
This service integrates slim double-glazed units into existing sash frames using traditional methods. Bespoke hardwood sashes with individual panes replicate original designs while providing modern insulation benefits. The installation maintains authentic appearance both internally and externally, eliminating the need for full window replacement and preserving period features.
Cill replacement
Specialised cill replacement addresses rot-damaged window bases through precise timber matching and waterproof installation. We restore structural integrity while maintaining original aesthetics, using traditional joinery techniques. This critical component replacement prevents water ingress and extends window lifespan, particularly for ground-floor units exposed to weather.
Draught-proofing installation
Our draught-proofing system eliminates air leakage through precision-fitted brush strips and sealing mechanisms. Installed within window frames without altering visual appearance, this solution significantly reduces heat loss and external noise. The system works in conjunction with restored sash mechanisms to maintain operational efficiency without compromising historical integrity.
Window restoration
Comprehensive window restoration combines structural repairs with cosmetic refinishing to revive original condition. Services include parting bead replacement, pulley system servicing, and traditional paint preparation. We specialise in Grade II listed properties, employing conservation-approved techniques that balance modern functionality with historical accuracy for period homes and heritage buildings.
