New Windows

With great expectations a local small contractor installed our new Pella windows in the living and master bedrooms.  The were almost finished today and they will be back tomorrow to finish the other area.  We were very pleased until I felt the air coming through the windows at the hinge area of the casement window.  The wind was hardly even blowing – what happens in a 25kt SW wind?  The contractor is bringing out the Pella Window Rep next Friday around noon.
