Horsham sash windows
Traditional sash windows and casement windows are an essential feature of a period building’s character. However, maintaining these traditional features previously meant compromising on comfort.

We believe in repairing sash windows to extend their lifespan, but for windows that have gone beyond the point of repair, we can craft complete new sash windows and casement windows.
