Our Core Values
At DRN Sash Windows Ltd, we believe in the enduring beauty and functionality of traditional wooden sash windows. We are dedicated to providing our clients with the highest quality restoration services, breathing new life into their historic windows while preserving their architectural integrity. Our commitment to craftsmanship, transparency, and customer satisfaction sets us apart.
Restoring the Elegance of Your Sash Windows
We understand that old sash windows can often become draughty, noisy, and inefficient. Our team of experienced carpenters undertakes a meticulous restoration process, retaining as much of the original joinery and glass as possible. We begin by carefully removing the sash lights, also known as the sliding parts of your windows, and sanding down all timber frames to identify any areas requiring repair or replacement. In cases where substantial damage is evident, sections of wood are skillfully replaced, ensuring structural integrity and a seamless finish. The broken glazing is meticulously replaced, and all putty and beading is repaired or renewed.
We pay close attention to every detail, checking the weights and cords of each sash window to ensure smooth operation. Our expert carpenters then apply a refreshing white primer to all the timberwork, preparing it for a long-lasting finish. Finally, the sash lights are carefully re-assembled, incorporating new fasteners and security ironmongery where necessary. Throughout the entire process, we maintain stringent standards of cleanliness and security, restoring your property to its original condition upon completion of each day's work.
Meeting Your Needs: Double Glazing and Secondary Glazing Options
We recognise that some clients may require additional insulation and noise reduction. For those who wish to maximise energy efficiency and acoustic comfort, we offer the option of double glazing for their restored sash windows. Double glazed units can be seamlessly integrated into existing frames, providing excellent thermal performance and minimising external noise.
For properties where budget or planning restrictions require alternative solutions, we also offer secondary glazing. This innovative technique involves the installation of an additional layer of glazing within the existing window frame, significantly improving insulation and reducing noise penetration.

- Providing honest and accurate assessments of your window restoration needs.
