We believe it is important to be a sustainable business and are proud to have achieved Carbon Neutral Plus status.
Beautiful Accoya wooden windows and doors
Are your windows or doors rotten or letting in the cold weather, resulting in high heating costs? We manufacture energy-efficient new sash windows, wooden casement windows, external French doors, front doors, stable doors, sliding doors, and bi-fold doors at our workshops in Berkshire.
We also supply and install secondary glazing and new sashes into existing frames (replacing just the moving parts) for timber windows. Our repair services comprise draught sealing and minor repairs.
The majority of our replacement wooden windows and doors are double-glazed. However, we can also manufacture single-glazed windows and doors or use our heritage glazing when required for listed buildings and some conservation areas.
We use a timber called Accoya, which is highly durable and stable. Accoya is a sustainably sourced timber that comes with a 50-year anti-rot guarantee.
All our new windows and doors come fully factory finished and draught-proofed to help improve the soundproofing and energy efficiency.
