When a new window was needed, Window Seal West really came through. From the first appointment with their Project Manager, Max Mateisen, to the visit for measuring, and finally the installation, they were always on time and efficient. The installers functioned like a well-oiled machine, and the drop cloths they put down to protect the floors were really appreciated. The installation itself took the amount of time they said it would, and the window looks and works great! I'm pleased to be able to shop local since they have their own manufacturing facilities here in Calgary, and am looking forward to working with Window Seal West later this year to replace the remainder of the original windows in the house.
