How to check a seal between sash and frame
A contractor yesterday replaced a few casement sashes and I noticed several problems. In many places it looks like there in no good seal. I inserted a piece of paper between sash and frame and closed and locked the window. In some places the piece of paper just falls by itself. In others I can simply pull it out with no force at all. It that normal? What is the good way to check the seal between sash and the frame? These are wood sashes made as a replacement for Scherer brothers windows.
