Hi, I was looking for some advice on the renovation of sash windows. I have found a website that sells diy renovation kits (www.diysashwindow.co.uk) and I was wondering if anyone out there had tried them and if they thought they were value for money and effective. I am mainly after the draughtproofing elements of this kit and this seems to be the only place I can get this, unless someone else knows of other suppliers of the correct type of brush seals. Any advice gratefully received.
