The finished product, sash window restoration completed just in time for Christmas. Professionally painted inside and out and new locks fitted. All non-moving windows with multiple glazing bars at the top are fixed back in place with 24 separate double glazed units installed. Small separate glazing units were installed to keep the original construction of the windows and character of the house rather than one larger unit with modern adhesive glazing bars stuck on which can make the windows look like upvc . All sash windows are working smoother than they did originally because we replaced all of the original pulleys with modern brass ones that use ball bearings to enable a quiet, smooth operation. With the double glazing and draught-proofing throughout these windows will be looking and performing perfectly for many, many years to come.
