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.

Review from google
We had a wooden sash and case double-glazed window at the back of our house replaced. The original was old, rotting, and the double-glazing seal had broken so that there was a lot of condensation between the panes; it was also not a very big window. We wanted to replace it with the same (but of course in good condition!), but it was almost impossible to find someone who was willing to come out to us (we're in East Lothian) for just the one window, especially one that had to have a wood frame (we're in a conservation area with strict rules). Eco Sash and Case were not only prepared to come and assess the job, quote fairly, and check to make sure that we were happy with all the details before proceeding, but were unfailingly friendly and approachable. They did the job when they said they would (in fact, they were able to get the painting done earlier than they thought, which was much appreciated), and the team were capable, quick and efficient. They took care not to make a mess and they left the room clean and thoroughly hoovered to remove any sawdust; the painter also took care to repaint our sill in our own paint, after doing the frame in the requested white. As the room is our bedroom (and not an easy room to navigate, with beams etc.), we are incredibly happy to have had this all completed before the winter really sets in. It was not cheap, but it was a fair price for all the work involved in producing and fitting a custom-made, very nice-looking window.

Unlike other companies, ES&C advised that we could retain the current frame and fit double glazing glass at a very reasonable price and without the need to put scaffolding to the 3rd floor. Other quotations we got at the time were three times the price we paid with Eco Sash. The team was on time and the quality of the work excellent! Joiners did a brilliant job, left the house the same way as before they started, and the painters we also excellent! We have noticed a massive difference in terms of heat retention, reduced use of heating and of course on the window condensation. Overall excellent service from Lindsay and the whole team, would highly recommend them.

Full package including arranging for listed building consent, the joinery and painting. Very happy with the look of my new windows and the workmanship. The work all went smoothly and both the joinery and painting teams were very neat and tidy as well as efficient/professional and very pleasant to deal with. Communication with the Office was good and proposed dates were met. Very satisfied customer.

Very happy with my new windows and the workmanship. The work all went smoothly and both the joinery and painting teams were very neat and tidy as well as efficient/professional and very pleasant to deal with. Listed building consent was part of the package and my early Victorian main door flat now has new double-glazed & astragalled windows which look excellent. Communication with the Office was good and proposed dates were met. Very satisfied customer.

We had sash windows draughtproofed, plus new mastic and painting inside and out. The lead time was quite long, especially waiting for the mastic & painting. The result is excellent. Communication was easy, with all email enquiries dealt with promptly.

Review from trustpilot
The company offered a competitive price for upgrading my single glazed sash and case bedroom windows to acoustic glazing. Unlike competitors, Eco advised that we could retain the current frame and fit acoustic glass - other companies suggested I would need to get a completely new frame, which was more expensive. Communication from the admin team was good throughout, although there was a delay of a few weeks over the course of the project due to other works overrunning, which was a bit disappointing. The installation team was great, arriving on time and efficient. I had to ask the painting team to come back to fix a couple of snagging issues which, to be fair to them, they did the very next day. The glass perhaps doesn’t block out quite as much noise as I’d have liked, but I think that’s mainly due to the materials/design of sash and case - the windows do look great, though. Overall I’m pretty happy with the service I received.
