Specialists in sash window and door renovation, refurbishment and draught proofing

We put a stop to draughts, poor thermal performance and unsatisfactory operation when it comes to your hinged casement windows, hinged windows and sliding sashes. Our team works tirelessly throughout London: supplying all areas from Hampstead to Holloway and Westminster with draughtproof windows.

Effortlessly restoring your traditional windows and doors

Sliding sash windows, hinged casement windows and doors all have a 2mm - 4mm gap around them, which allows them to operate and to move, as required.


If left unsealed, this gap will result in draughts, rattling frames and dirt ingress. None of which are desired traits when it comes to your new windows and doors! Thankfully, we have the perfect solution for sash window draught proofing.

Great work

Genuinely great work by these guys. I had 6 sash windows refurbished and draught proofed. Stuart and the office were on it from the start, and most helpful. The team who came to do the work were punctual, courteous, pleasant, tidy, and just got on with it, and I'm very happy with the result. Thanks!
