We enjoyed the salesman. Wouldn’t have purchased the windows if we didn’t like his pitch. He did say it would take only one day-which I should have known wouldn’t be the case. In reality my husband and I had to take of closer to 4-5 days. Can’t recall exactly it’s been a few months. Also, expect people who smoke to find a way to smoke even though again, I was told that was not going to happen around my house. Oh well. Windows are nice for what we paid. There were hiccups along the way to get to nice but we are happy now. All the service men were pleasant to work with. So far winter I’m Wisco has been mild but the windows seem to make a big difference.
