About Us

sashwindowsSash Heritage Restoration is a Brighton based company working all over Sussex and further afield if required.  We restore and refurbish almost any sash and casement window using carpentry, joinery and the Dryflex Woodcare System. Your windows will look pristine and new again, be draught-proofed and last for years.  We are probably one of the only companies that restore and refurbish sash and casement windows from start to finish.  We are meticulous when it comes to restoration and refurbishment of traditional wooden windows - your Heritage property deserves nothing less and it costs no more than a complete replacement.

Customers searching the Internet, Checkatrade and elsewhere have often told us we are the only ‘one stop shop’ (as they put it) that they could find. Please note we are a small firm with dedicated craftsmen and we never subcontract to other companies.  We only supply skilled carpenters, who promptly travel to your site and do the whole job between us.  We completely strip all the old paintwork back to bare wood first.  After meticulous preparation, we apply an essential undercoat followed by two top coats, only using top-quality interior and exterior paint while decorating, which results in a superior finish.  Our interior paint does not colour with age, and is resistant to knocks from furniture, animals and children.

We fully glaze using float glass cylinder glass, Slimlite double glazing or laminated glass which can all be fitted to your original Heritage sash and casement windows.  All carpentry and joinery included with the Dryflex Wood Care system is used for a permanent fix as explained on our dedicated pane repairs and Dryflex pages.

Restoration of Heritage Sash Windows

Sash Heritage Restoration Ltd is the only company you will need to call, to fully refurbish and restore your sash or casement windows.  We are a small company and do not sub contract or try to recommend other trades as it is a fine art to restore and refurbish a window and all trades need to work together at the same time not bringing in one after another trade.  Our treatments prevent all exterior paintwork - which very often needs restoring - becoming loose and damaged over the years. 

  • We carry out full decoration and preparation on the interior and exterior of all sash and casement windows.  
  • We use the best quality weather shield paints which are 10 year proven
  • We use exterior weather shield paints to the interior for a longer lasting finish
  • We fit only high quality draught excluders

Most importantly, for all sash and casement windows, when restoring and refurbishing only full quality draught excluders are fitted helping to give smooth draught free operation of the windows, especially when the often thick congealed old paintwork has been removed completely back to bare wood.  It is senseless to fit draught excluder before preparation has been fully completed.  Full decoration cannot be carried out properly if this is not done first. 

Caring for Kiln-Dried Timber

Instead of insisting on new windows, we restore your windows to their original structure. Brand-new windows do not last due to the properties of kiln-dried timber. Kiln-dried timber dries on the outside more quickly than the inside, causing hardening and shakes. Timber must be equally balanced with its surroundings. This may only be achieved with air-dried, seasoned timber.

New sash windows are made from soft kiln dried wood that does not last - unlike your original beautiful, original Heritage sash windows which are made from old seasoned wood; newly made sash windows made from kiln dried timber rot a lot quicker and the paint does not last as long. Also, any new sills required would be replaced with a hardwood sill so the sash window will last a lot longer.

The Ultimate Treatment for all Sash and Casement Windows

We have years of experience at keeping the beauty and splendour of our glorious Heritage which we feel is especially worth preserving - when modern materials can let us down within a relatively short time, properly seasoned wood which has lasted for over 100 years can be restored and look as good as new and cost less than simply putting in new, too.  So don't give up on your historic sash and casement windows - they can be restored!  Sash Heritage Restoration will carry out all work from stuck windows, replacing sash cords and re-glazing.  Rotten window sills are always replaced with hardwood, rotten areas to any sash or casement window, box frame areas and sills, etc will be repaired with expert carpentry and the Dryflex Woodcare system which is a permanent fix - all other fillers do not last.

We are experts in restoration and refurbishment of all sash and casement windows to all grade listed buildings, conservation areas, Victorian terraced and semi patched properties etc as shown on our dedicated pages.
