Hi guys
One of my Windows seems to not shut flush anymore when closing. As you can see from the photos when I shut the window or push from the inside, at the hinge side (top left) it opens at the bracket slightly and no longer closes flush. As you can see it's worse on the small window. To get it to shut flush you have to push from the outside or pill as you close the window. Unfortunately it's a top floor window.
Any idea why this is happening and how to remedy??
