But this seems to be a different set up than most, we don't often see exterior wood trim right up against the glass.
Can you explain what we are looking at.
In that image the white is the wood trim and the dark brown on the inside is the Anderson replacement casement window. The windows were smaller than the originals so they were shimmed and then the space covered with the white wood.
I dont think water can get in there because the fit is so good but my idea is that paint wont protect it enough and after years the wood will rot from rain/Ice ...
