This home in Jenkintown. Pa. recently had a new Bay window installed replacing an old bow window. When installing a bay or bow window it is important to have a cable support system installed to prevent the window from sagging. As seen in these pictures there are cables running through the window frames, and then anchored into the brick. Once anchored the turn buckle pulls the window to level. This process assures the window will stay level, and the windows will open and close with no chance of air infiltration. Once completed a new roof pent is installed to protect the top of the window from the elements.
