I just had my Gilkey windows put in a few weeks ago. So far they are great. However, it did take a lot longer than 8 weeks for my windows to arrive (I had one very large picture window which I was told was the hang-up). It took closer to 14 weeks.
Is your salesman Bill Boesch? He was very nice. Just make sure if you are ordering grids that you draw them on the contract. There is no place on the contract to confirm the grid pattern. We wanted Prarie but they came with Colonial. They are taking care of it and have ordered replacements. But, I wish they'd arrived just as we'd ordered.
I was referred to Gilkey from a neighbor. One of her windows developed some crystalizing between the panes in the winter indicating a seal was damaged. Gilkey replaced the window right away, she said it was a painless customer service call.
