Here you have indicated that the windows do not close. That is, if they are closed during the test, then they are fine. Did I get it right or not at all. I would, for example, better check their condition rather than just close them or not. After all, the closing of the window in general can be adjusted if, for example, a sash sagged. Unless the
windows ottawa is old wood and it sagged, then there is a little more complicated. I think to me to such moments should be treated more seriously as a replacement window after the purchase of the house will not be the most pleasant gift for its new owner. Do you agree with me? Or did you just briefly point out that you also check the windows? Maybe I just misunderstood you.
