Services
New Sash Frames
We manufacture custom sash frames to fit existing boxes, available in single or double-glazed options. Frames are crafted from durable, sustainably sourced timber with thermally efficient glass and draught-proofing features. Our precision engineering ensures seamless integration with original designs while enhancing energy efficiency and security.
Window Restoration
Our restoration process revitalises aged sash windows through rot treatment, timber splicing, and rebalancing. We preserve original features while improving functionality, including draught-proofing and security upgrades. This service extends the lifespan of heritage windows, maintaining their aesthetic and structural integrity for modern use.
Thermal Insulation
We install double-glazed units with argon gas and warm-edge spacer bars to achieve 1.1W/mK U-values. This reduces heat loss, noise pollution, and condensation while maintaining traditional window aesthetics. Our insulation solutions significantly lower energy bills and improve indoor comfort without compromising historical accuracy.
Draught-Proofing
Our draught-proofing systems use weather stripping and beading to eliminate gaps without altering window appearance. This improves thermal efficiency and reduces dust ingress, enhancing comfort and energy savings. The process is compatible with both modern and period sash windows.
Sash Repair Kits
We provide comprehensive draught-proofing kits containing staff beads, pile carriers, cords, and fasteners for self-installation. Each kit covers windows up to 2x1m and includes step-by-step instructions. These cost-effective solutions allow homeowners to upgrade window performance independently while maintaining traditional functionality.
