Hi, Can anyone help please? 3 of my upvc window are filling with water which is rusting the handles and presumably mechanism, from inside the bottom rail (the water is in the part surrounding the glass and filling the bottom rail if that's the right word). The window surround seems sealed with no drainage holes on bottom, top or sides. The actual window frame has drainage holes and seems fine. I don't know how the water is getting in. How can I solve this? Can I drill holes into the window surround? Would have to be sides as bottom seems to be taken up by the metal window mechanism.
All 3 are large top opener window with handle at the bottom.
