Just had a room replastered and after it had all dried out we had quite a lot of heavy rain. I have now noticed to wet patches quadrant shaped at the bottom corners of the window frames on the new plaster could it be the outside beading,and if so how do you remove beading to reseal it,is it just stuck in place with silicone (all though it looks ok) or can water leak past the glass unit. There is no water on the inner sill just the damp plaster.
Thanks for any help
