Pella Window Air Infiltration
In the fall of 2009 I replaced all (18) of my double hung windows with Pella Precision Aluminum Clad Wood replacement windows purchased from Lowes. The first winter I noticed some air infiltration on the sides of the lower sashes which was corrected between my contractor and Pella. Now 4years later, with the extended cold NE weather, I am noticing drafts around all the windows and in a few cases I can nudge the lower sash to one side and see light along the opposite side. Pella refuses to accept any responsibility for the problem Needless to say I am very disappointed. Has anyone else had this problem and is there a fix short of replacing all the windows.
