Draught Proofing & Renovation 

Sliding Sash Windows, Hinged Casement Windows and Doors, have a 2mm - 4mm gap around them to allow them to operate and to be able to move. This gap, if not sealed will allow draughts, rattles, dirt ingress from the busy London life and noise in to your property.

We use the UK's No.1 Sash Window Draught Proofing System supplied by Draftfix Limited ( www.draftfix.co.uk ) to combat the draughts, dirt ingress and noise pollution.

The specialist, high performance system has been tested to conform to the highest standards and this can be found here.
