Used allmar to get my windows for my basement open floor plan, they had a selection book that i could pick from, and they helped with picking a size to make my basement look open, they also installed the windows, and did a great job, quick service, but they didn't clean the windows as promised after the installation so i had someone come do that for me, make sure you request the cleaning of the windows after installing and make sure you have them do it before they leave.
