Sash Window Replacement Project – Bearsden, Glasgow
This project involved the full replacement of every traditional timber sash and case window in a beautiful period home located in the Bearsden area of Glasgow. The homeowners wanted to retain the elegant, traditional appearance of their original windows whilst significantly improving energy efficiency, comfort and usability throughout the property. As with many heritage homes, the aesthetic was incredibly important, so the new windows were bespoke and tailored precisely to the client’s specification.
Bespoke Timber Sash Windows: Tradition with Modern Performance
The existing single-glazed units were replaced with handcrafted, energy-efficient double-glazed timber sash windows, designed to replicate the original profiles and sightlines. Each frame was manufactured in high-quality timber and finished either stained or painted to the client’s chosen Farrow & Ball shade, ensuring a flawless match with the home’s character and décor.
The new double-glazed units significantly reduced heat loss, draughts and external noise while maintaining the elegant, slim-profile style that suits period architecture. From joinery detailing to glazing specification, everything was carefully considered to respect the traditional look of the property while meeting modern performance standards.
Craftsmanship, Care and Attention to Detail
The homeowners had every window in the house replaced, which can often feel like a daunting undertaking. However, our experienced installation team completed the project with precision, care and minimal disruption. The full works were carried out cleanly, efficiently and respectfully, with a strong emphasis on protecting the interior finishes of the home throughout the installation.
Our clients, commented:

We are absolutely delighted with the quality of the job, and wouldn’t hesitate to recommend them.”
