Found one of outside (we are too far from property to go back). The window is fine but I think there’s salt marks up the wall. There are old studs in the bricks so something has been done at one point. The photo was to ask to cut the wires!
Hi Kevin, when you say capped off do you mean the chimneys capped off, if so if so did they put air bricks in the chimneys if not then I think you will find it is a build up of condensation with no where to escape. Hope this helps Kevin. ...
