The top wooden opening is also perfectly level. Is there any way the upper latch can be aligned better. Fortunately there is no air leaking through.Ģ. If not is there any better way to caulk this to avoid the unsightly gap. Is it OK to put a screw in the top vinyl header in the middle of the frame so that the trim is flush with the top opening so that it can be caulked for a semi-permanent repair.

I was hoping to get some guidance on the followingġ. The top latch of the sash is not aligned with the catch on the other sash behind - however if both sashes are pushed apart with some force, the latch can be closed. That has caused the trim to detach from the top opening.

The window frame is sagging a bit in the middle (based on a long level). Am guessing they made the windows 3/4inch too short.

The top header of the frame (inside) has trim running along the width which was caulked to the top opening. The frame is about 4' height by about 6' width with each sash about 3.75' high and 2.75' wide.

I have 14 year old large horizontal sliding custom vinyl windows.
