Timber Windows London

Wooden casement windows

We custom make two styles of casement window, the first being the traditional square edge flush casement window which is hung on butt hinges and secured by stay bars and cockspur handles.  The other being a stormproof casement window which is hung on friction hinges and secured by a multi point locking system.  Both styles are manufactured using rebated sections and are fully draught excluded.  In addition all glazing is beaded internally.


All our casement windows are made to order in our workshop located in Essex by our highly skilled team of carpenters.  We offer a full replacement service which includes a new internal window cill and architraves should they be required.  If you are looking to achieve a Georgian or cottage style casement window then we manufacture a 32mm glazing bar which can accommodate a double glazed sealed unit.


We have an extensive range of glass options for you to choose from which includes any design of leadlight, various obscure patterns, clear, coloured, toughened, acoustic sound deadening and laminated glass.


Safety is of paramount importance to us therefore all our low level and bathroom windows are fitted with toughened glass as standard.

In addition our sealed units are all double glazed with softcoat low emissive glass, a warm edge spacer bar and are argon gas filled.

We finish our casement windows with three coats of microporous paint or wood stain, alternatively we can source a brand or colour of your choice.

Whatever your requirements we are always happy to discuss your plans and offer a free no obligation quotation.
