City Window Services LTD offer draught proofing, sash window repairs, double glazing of existing wooden sash windows, and full sash window replacement throughout London and surrounding areas. We keep it simple from the moment you get in touch – we pop around for a brief on site inspection and offer free advice, and a free no obligation quote, with a bias toward repairs and preserving your original sash windows. We will not attempt to sell you replacement sash windows, we consider repair and use of your original joinery to be the best option. City windows are not inclined to throw out quality joinery (that’s already stood the test of time might I add), when simple repairs and overhaul can make good on windows that are possibly a hundred and thirty years old or even more. All too often sash windows in period properties  are replaced with uprated wooden double glazed sash windows when double glazing of the original sash window many have been a viable option, or worse, inferior UPVC replacement with only short term costs and benefits considered.
