Even windows that appear to be beyond repair can be fully restored.

It costs less to restore an original sash window in this condition than it does to replace it with a new window. This traditional historic Edinburgh sash window was handcrafted about 130 years ago. About 95% of the original timber was still of solid sound condition. It just needed some TLC to repair it to its original handcrafted condition. After our repairs, and if maintained, this original handcrafted sash window will last decades more to come. Interactive image slider.

Been told you need to replace your original sash windows?

Replacing sash windows can be expensive and cost 3-4 times more than restoring them. We can restore your old and rotted sash and case windows back to their original crafted working condition, even if you have been told, they are beyond any repair! Our work is fully guaranteed and offers huge savings on replacing your original sash windows.

This is an old video of our work that was restored with materials available at the time but has proven to be very popular on Youtube. The window was handcrafted about 140 years ago. About 40% of the window was just a mash of rotted wood. It required a lot of TLC + to restore it. Today we have even more modern materials and techniques to restore your original sash windows that will last for decades to come.

Trustpilot Review: Dr. J Sutherland, Edinburgh.

We are extremely happy with the service that EPS provided, and the quality of work completed. We had been told by various tradesmen that one of our sash and case windows was in such a poor state of repair that it required complete replacement, at considerable cost and disruption.

EPS Sash and Case, however, was able to fully renovate the window to such a high standard that you would not know the extent of the work done. We found them to be extremely professional, and would not hesitate to recommend EPS Sash and Case.
