Stuatt Batten

I could not fault the service provided by eco sash and case. Very friendly and informative, explaining the window renovation process and use of eco friendly products. A courtesy call the evening before work, arriving on time, putting down dust sheets and hoovering up afterwards. The workers were very friendly and helpful . Very impressed with the work carried out and excellent value for money. The draught proofing they installed has worked wonders. Highly recommended.


Stuart Granger

From the initial survey to full completion, we felt confident that we had chosen not just another double glazing company but one with consideration for traditional sash windows. The double glazing has been installed and is unnoticeable in appearance. What is immediately noticeable is the temperature change in our home.


Edward Adams

Other estimates we received said we would need to replace our old windows with new windows where ECO Sash & Case said they could save the original sash windows and fully restore them, this really brought the cost down. We are so happy with their work, but more so they carefully restored our old sash windows. The warmth of the room is now amazing. Thank you for all your hard work.
