I have had nothing but trouble with Pella. While their employees are very polite, for the past 9 months Pella has been unable to properly install a 3' full lite rear entrance door. There is nothing unusual or unique about the construction of my house or the location of the door. They have been out 4 times, and each time they come out (to replace the lite, or the threshhold, etc.) the installers do more damage. There are stripped screw heads everywhere. During their last visit, they scratched the finish of the (new) Baldwin door hardware. The interior trim installation was especially shodding -- none of the joints line up. Everytime they come out, instead of using a new piece of trim, they keep trying to adjust the original trim they installed -- obviously they aren't very bright.
I have taken pictures and am preparing a letter for Mel Haught (Pella's CEO).
