Trying to decide how best to tackle our basement windows
We have three of these basement windows and I am trying to understand them so I can replace or repair them. They slope inward which is bizarre to me as it lets water just flow inside. There is an interior wooden framed window that you can see in these photos, it opens inward and lifts upward. Plus an unattached metal window that theoretically attached to the metal frame remnants and opened outward (we have the windows though two have broken glass). And then there appears to have once been a nailed in screen on top of that.
So fellow old house owners of reddit, how would you tackle these windows? Repair and reinstall the original windows? Scrap it all and do new windows? What about that weird slopping inside?
