me again, this house move is proving challenging and you are my only form of regaining some sanity! my bathroom window appears to have a gap when shut. Admittedly when looking at the other windows i think they had a sale on window parts and "have a go fit yourself day". My main aim, for now, is to have the window usable but also to stop the cold coming in as i think this is the main source for it (the open fan in the shower and the not needed overflow pipe *might* also have something to do with the extra air con . is there something i can alter? or can i buy something to increase the thickness of the "black rubber seal"? sorry for all the questions chaps! if you look to the left side i think you can see the gap and it feels as though air is coming in from that area so i assume the gap is actually a gap? ive also included a snap to show that the window is shut and that it seems to be wider at the left side (the 3rd pic showing along the top but its orientated sideways - sorry!). Please excuse the state of the bathroom, its a work in progress.
