The best way to draught-proof an old window or door

Posted by Cathy Debenham on 7 February 2011 at 9:11 am

However high you turn up the heating, a cold draught howling around your ankles is still uncomfortable, yet lots of the products on sale at the DIY shops don't manage to cut it off.

Well, thanks to English Heritage, by way of Hook Norton Low Carbon, I've discovered the answer for casement windows and doors. It's silicone bath sealant and vaseline.

First clean the window casement or door and the frame and edges thoroughly, removing loose paint (and mould if you've got it). Dry well.

Spread a generous layer of vaseline along the edge of the casement or door along all edges. Shut the window / door and fill the gap with silicone. You can smooth it off with a wet finger, or knife.

Leave it to dry for 24 hours. As long as you got the vaseline right you will be able to open the door, and find yourself with a custom fit seal that exactly fits the gap, however uneven it is.

As I've got lots of plastic windows, I haven't tried this myself. But if you do, please let us know how well it works in the comment section below.
