A friend recommended Adam. I called Adam early May didn't get a call back until early July. I gave him a deposit and by late July 2016 he installed my windows. After the first rainfall in early August 2016 8 of the 12 windows installed were leaking. I called Adam numerous of times but with no call back. I had another Window company fix all his errors which cost me more money. Don't call Adam at Ultimate Windows as you will go through this as well. I wish didn't call.
