Sliding Sash Windows
Vertical sliders for period elevations.

What are sliding sash windows?
Sliding sash windows open by sliding vertically, the traditional window of Georgian, Victorian and Edwardian houses.

Questions
Can I replace sash windows in a conservation area?
Often, but it depends on the property, any Article 4 direction and the local authority. Listed buildings require listed building consent. We check before quoting.
How much do sliding sash windows cost?
There is no meaningful fixed price. Cost depends on size, configuration, glass, colour, hardware, access and the complexity of installation. We provide a written quotation against an agreed specification, typically within 48 hours of having the details we need.
