In June 2020 I had Empire install replacement windows in the upstairs of my house. The process was easy, the sales team was awesome. I had sat through multiple 60 minute plus presentations. I am confident the window I purchased is the best window I could get. HEAT MIRROR TECHNOLOGY, unbelievable. It's like standing next to a see through wall. I'm so happy with Empire I just signed on to have them replace the rest of my windows in 2021! Cheers to Empire!
