Is your home suffering from draughty, deteriorating, or inefficient timber windows and doors that impact comfort, appearance, and energy bills?
At The Sash Window Workshop, we specialise in manufacturing, and installing high-performance timber windows and doors — expertly crafted in Berkshire and built to last for generations.

We provide a comprehensive range of services tailored to period, listed or contemporary properties, including:

• Sash windows and casement window replacement – enhancing aesthetics, efficiency, and long-term performance and typically double-glazed for superior energy efficiency and sound reduction.
• Bespoke front doors, French doors, bi-fold and sliding doors – combining refined design with robust security.
• Secondary glazing – discreetly boosting thermal and acoustic insulation without altering your property’s character.
• Draught-proofing and specialist timber repairs – extending the life of your existing joinery with precision craftsmanship.

For listed buildings and conservation areas, we also offer authentic single-glazed and heritage-glazed solutions that meet planning requirements while delivering exceptional performance.
