The existing double hung windows worked on a weight and pulley balance system that is buried in the frame of the window and was very common in wood windows years ago. When we install our window, we are sure to access the frame to remove the window weights and pulley system and insulate the cavity created with this system before installing the new windows. For us, it’s common practice however to some they may not even realize it. Not only did the installation go smooth the exterior turned out great and provided a no maintenance wrap on the outside.

We kept the existing width of the opening and made sure that the window was at the same height as another window in the room. When we use the same width as the door to install a window it’s smooth sailing as there is no need for any structural changes so we quickly had the window in and ready for them to complete the outside finishes.
