Upper sash on 20 year old windows falling
I recently bought a new house and our inspector found our double hung windows needed some adjustments/repairs. A bunch of the windows in the house have falling upper sashes. When the window is closed/locked, the upper sash will actually not seal all the way to the top of the jam. You can use your hand and lift the locked upper sash into place. in a few cases light can be seen through the gap. These windows do not fold out for cleaning. I can see some springs in the jams, but I am pretty sure they are for the lower sash. I have attached a picture of the lock section as they seem to be original. if you need a better pic for identification I can upload another. I would love to know who made these windows...and how to fix the problem.
