Services
SashCo window repairs
We specialise in repairing and refurbishing traditional sash windows to extend their lifespan. Our process includes draught-proofing, repainting, and hardware replacement while maintaining original architectural features. This service preserves property character while improving energy efficiency and security.
UPVC sash windows
Our UPVC sash windows combine traditional aesthetics with modern performance. Features include low-maintenance profiles, tilt-in sashes for easy cleaning, and optional decorative horns. Available in various colours and finishes to match different property styles while meeting current energy efficiency standards.
Triple glazing installation
We install triple-glazed windows offering superior thermal insulation and noise reduction. With U-values below 1.6, these windows significantly reduce energy bills while enhancing security. Ideal for properties in noisy urban areas or requiring maximum thermal performance.
Bespoke window design
Our made-to-measure windows ensure perfect fit for unique architectural requirements. We create custom profiles and mouldings to match existing features, particularly valued in conservation areas. Options include traditional astragal bars and period-appropriate cill designs.
Heritage window restoration
We provide historically accurate window solutions for listed buildings and conservation areas. Our timber-framed windows replicate original designs while incorporating modern energy-saving features. All installations comply with heritage regulations and building standards.
