We had 1 window & sliding screen door replaced 10/2015. We were very pleased with both the service John provided us during the whole process as well as the installation process. Due to the service we received, we decided to have the rest of the windows replaced on the house 2/2017. It was no surprise that the service the second time around was just as professional as the first time. The prices are reasonable and the quality is better than I expected. I will use Imperial again and I definitely recommend Imperial Windows to others
