Customer satisfaction

Teresa and I are very pleased with the picture window installation today. Matt and Keylan were accommodating to my request to save the window sashes. The installation of the picture window (replaces two side by side casement windows) changed the look of the interior Great room . We love it. Thanks to the entire team at Asher as well as to Matt and Keylan for quality installation.

Nick & Dalen were our installers and made the whole process seamless. They went above and beyond and even helped us problem solve some water drainage issues they discovered we were having. Our new windows made our whole house seem brand new! They looked so nice we didn’t want to put the blinds back up! We live on a busy street with lots of traffic. The first thing we noticed is how quiet everything was. We couldn’t hear the trucks driving by. Nick and Dalen kept the house clean inside and out and even our dogs liked them. Definitely five stars and highly recommend.
