Two sets of windows on the second floor of our house fall out, due to too much space between the window and frame area. It's tight enough at the corners of the frame area, but not in the middle. In fact, I'm able to pull both windows right out with little trouble.
Here are some photos:
I'd love to hear suggestions on how I'd be able to fix. Would I be able to take off the top white flashing material and add some wood/shims? Or is the best option to add smaller pieces of wood to the top of the windows themselves to extend them upward? As the window frame seems taller in the middle (that's the really loose area), I'm thinking adding some shim material to the frame under the white part might be best.
Do products exist out there, to help with this kind of scenario?
