Bought Pella windows and had them arrange to install them. Took 10 months to complete the job. They lost the orders, the windows, my requests,etc., and didn't follow up on any of the problems or corrections they needed to make. Had no accountability for anything. I got different answers every time I called them. Horrible experience! Use them at your own risk (they've got big problems). Better yet, find someone else to buy from. You will be a lot happier.
