Not only are sash windows a much sought-after original feature by those buying a period property, they're also highly popular with self builders wanting to build a Georgian, Victorian or even New England style home. 

The way in which sash windows operate is quite different from other window styles, such as casement windows so whether you have inherited sash windows that are in need of some repair work, want to upgrade the glazing or thermal properties of your windows, are looking to replace existing openings with new sash windows or are starting from scratch, it is important to understand how they work, their advantages and disadvantages and what kind of costs you might be facing too.
