Our Sash Window Restoration Process

Restoring sash windows is an intricate process that requires precision and care. We follow a comprehensive step-by-step approach to ensure each window is restored to its original glory or updated to meet your aesthetic preferences while enhancing its functionality and durability.


1. Paint Removal Using CO2 Blasting

We begin by removing old paint and varnish using CO2 blasting, a gentle yet effective method that cleans without damaging the underlying timber. This environmentally friendly technique ensures that all surfaces are properly prepared for restoration.

2. Timber Replacement (if necessary)

Inspecting the window frames and sashes for any damaged or decayed wood is a critical step. We replace compromised timber with new wood that matches the original in both type and treatment, ensuring structural integrity and historical accuracy.

3. Functionality Repairs

This stage involves addressing any issues with the window's operation, such as stuck sashes or broken cords and weights. We repair or replace hardware to ensure smooth functionality, maintaining the window's traditional operation while improving performance.

4. Filling and Sanding

Any gaps or imperfections in the wood are filled to create a smooth surface. The entire frame is then sanded to ensure an even surface, crucial for achieving a flawless finish in later stages.

5. Primer Applied with Airless Spray

A high-quality primer is applied using airless spray technology. This method provides a uniform coat that seals the wood and ensures optimal adhesion of the topcoat, enhancing the durability and appearance of the paint job.

6. Paint Applied with Airless Spray

The final colour is also applied using airless spray technology, which offers a superior, smooth finish free from brush marks. This technique allows for even distribution of paint, resulting in a consistent and durable finish.

7. Sealing and Weatherproofing

After painting, we apply a sealant to protect the wood and paint from moisture and UV damage. This step is essential for extending the life of the paint and maintaining the functionality of the window.

8. Final Inspection and Touch-Ups

The last step involves a thorough inspection of the restored windows to ensure every detail meets our high standards. Any necessary touch-ups are made at this stage to guarantee the finish is perfect.

By following these detailed steps, we ensure that every sash window restoration project we undertake not only meets but exceeds your expectations, combining traditional aesthetics with modern functionality.
