Why 'Eco' Sash and Case?
Planting Scots Pine Trees
Our name is ‘Eco’ Sash & Case because sustainability is at the heart of what we do. When replacing traditional sash and case windows, we focus on energy efficiency, craftsmanship, and responsible materials.
As part of our commitment to the environment, we also plant a Scots Pine through Trees for Life for every completed sash window replacement project.

Our expert restoration service is designed to bring your original sash and case windows back to life. By sanding, re-puttying, repainting and re-masticing, we improve their condition while maintaining their original appearance.
Our replacement sash and case windows are handcrafted in our Edinburgh workshop using responsibly sourced Grade A engineered redwood and traditional joinery techniques. Each window is carefully made to match the original style, ensuring a seamless finish that is built to last.
If you’re looking to upgrade your existing windows to double glazing, we can retain the original case and fit your existing sashes with new double-glazed units. This improves energy efficiency while preserving the character of your original windows.
Our bespoke casement windows are handcrafted in our Edinburgh workshop using sustainably sourced timber and traditional joinery techniques. Designed to combine timeless style with modern performance.
If your casement windows are starting to look worn or draughty, a refurbishment can restore their appearance and performance while preserving their original character. From timber repairs and draught proofing to full repainting, our expert restoration work helps extend the life of your windows and improve energy efficiency.
Our painting and mastic service is designed to protect and preserve your sash windows for years to come. We use a durable 5-Coat Heritage Protection system alongside traditional sand mastic, providing a long-lasting finish that can last up to 8 years. Significantly longer than standard paint systems.
