Bespoke windows manufactured to order

At Sash Window Conservation, all of our windows are manufactured by us at our own factory in Staplehurst, Kent. We offer timber sash or casement windows as standard, but we are able to design and make any window or door that you desire, so long as it is traditional in style.

Having our own factory locally means we have been able to increase our manufacturing capacity by up to 40%. It also means that our customers’ orders are made nearby, making distribution quicker and products easier to customise. Thus, certainty of supply is assured.


Unique products designed to respect heritage

For historical buildings with windows in need of refurbishment, we offer expertise in repair and draughtproofing, using careful, traditional craftsmanship to return the windows to their original state.
