Over last summer I had my patio doors replaced with a pair of Andersen patio sliding doors.
Everything seemed fine till the winter set in. At first I noticed that there seemed to be a slight draft of air I could feel right at the vertical overlap of the fixed panel and the moving panel. The draft is only felt for the first foot or so from the floor - the rest of the overlap seems fine. I also started to notice condensation on the horizontal frame along the bottom length of the sliding panel.
We had a pretty cold winter this year and during some of the real cold phases, I had quite an accumulation of ice along the overlap as well as the frame along the bottom.
The contractor who installed it came over and tried to fiddle with the door but it did not help. I'm having Andersen come over to take a look at it.. but its a $132 to come take a look. If anyone has any ideas I'd sure appreciate it - it might save me a chunk of change.
Thanks in advance.
