Hi Rae. I’m delighted with my new stained glass window which was just installed this morning. Rather than removing the existing frosted glass window, my contractor decided to build a white wooden frame around the stained glass to secure it directly in front of the existing frosted glass window. That way we didn’t risk damaging your beautiful piece or worrying about the window leaking in the future. Since this window is in the second floor and not really visible from the street, this method was fine with me as it looks great from inside our guest bedroom which is all I cared about. Now it looks like a piece of art on the wall!
