BEFORE YOU REMOVE YOUR OLD WINDOW, IT IS IMPORTANT THAT YOU DO THE FOLLOWING:
1) Measure the window opening to ensure that you purchased the correct size window.
2) Measure the window itself to ensure that it will fit into the desired window opening. Window would be approximately ¼” less than the opening in width and ¼” to ¾” less in height.
