Restoration of Sash and Case Windows on Grade A Listed Building

Edinburgh Grade A Listed Building Repairs

We were entrusted with a prestigious project involving the restoration of sash and case windows on a Grade A listed building. This historical property, characterised by its architectural significance and heritage value, required meticulous preparation and painting of all 130 windows. Additionally, some windows needed the application of sand mastic to ensure longevity and structural integrity.

Project Challenge

Restoring a Grade A listed building in Edinburgh presents unique challenges, primarily due to the need for preserving its historical and architectural integrity. The specific challenges of this project included ensuring that all restoration work adhered to the strict guidelines for listed buildings, maintaining the building’s historical authenticity.

Our rope access team had to safely access and work on all 130 windows, some located at significant heights. We also needed to ensure that all materials and techniques used matched the original construction to preserve the building’s aesthetic and structural integrity.

Our Rope Access Solution

We approached the project with a well-thought-out plan, combining heritage preservation expertise with advanced abseiling techniques.

A detailed assessment of the building and windows was conducted to identify the specific needs of each window, including the extent of preparation required and the need for sand mastic application. We selected materials and techniques that complied with heritage conservation standards. This included the use of historically accurate paint and sand mastic where necessary.

Our rope access team comprised skilled operatives with experience in both high-altitude work and heritage restoration. Training was provided to ensure all team members were familiar with the specific requirements of working on a Grade A listed building.

The restoration project was executed in the following stages:

1. Safety Setup: Rigorous safety protocols were established, including the use of harnesses, safety lines, and continuous monitoring to ensure the safety of our team.
2. Window Preparation: Each sash and case window was carefully prepped. This involved removing old paint, repairing any damage, and cleaning the surfaces to ensure optimal paint adhesion.
3. Sand Mastic Application: For windows requiring additional structural support, sand mastic was applied. This material was chosen for its durability and compatibility with the building’s original construction.
4. Painting: Historically accurate paint was meticulously applied to each window, ensuring a high-quality finish that preserved the building’s aesthetic while providing long-lasting protection.
5. Quality Control: Upon completion, a thorough inspection was conducted to ensure all work met heritage conservation standards and the client’s expectations.

The Outcome

The project was completed successfully and all restoration work was in full compliance with heritage conservation standards, maintaining the historical and architectural integrity of the Grade A listed building.

The sash and case windows were expertly prepped and painted, providing a durable and aesthetically pleasing finish. The application of sand mastic to selected windows ensured enhanced structural support and longevity.
