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 sash window repair and preserving your original sash windows. 

Where you’re looking to do more than just maintain, we will help you to upgrade your sash windows based on your requirements both thermally and acoustically in the most cost effective ways. Over the years we have developed our retrofitting double glazing sash windows system combined with a hidden high quality sash window draught proofing system.


We can offer a range of glazing for safety, thermal improvement, and acoustic too. Just let us know what you’re looking to achieve and with our three decades of experience, we will provide you with the best options factoring in value for money too.

We will not attempt to sell you replacement sash windows if at all possible, we consider repair and use of your original joinery to be the best option in most cases where a balance of of cost and performance is sought but are still happy to offer new double glazed sash windows if you prefer. The best bit about our service (and don’t just take our word for it – see what our customers say) is that more often than not it is hard to tell we have repaired, draught proof, or double glazed your sash windows, even from just a few metres away
