I have placed an order for Marvin Ultimate Clad windows. I am very excited to finally get rid of the 25-year-old single-pane rotted-frame windows. This past winter's polar vortex situation was horrible. I had minus-20 outside and horrible drafts and thick ice dams inside my windows. So I am impatient for the new Marvins. I don't know why, but I expected a lead time of 3 weeks for the windows to get here. My contractor said this winter was so bad that everyone is like me and replacing windows. Resulting in backlog. I am curious, what is this forum's current experience as to lead times?
