Step 1: Make sure the storm window is appropriate for the opening. The top of the storm window should be determined by checking the direction of the movable panels. Keeping the storm window in the opening and checking if all the screw holes land on the wood is necessary.

Step 2: If there is an old window, remove it.

Step 3: The top and sides of the existing window opening should be coke. Considering that the bottom is not too close. Holding the Caulking gun at an angle of 45 degrees on the edge of the storm window, using a “pulling” motion, holding the gun at a constant angle. The caulk is to slide the tube nozzle with the joint while pressing the trigger of the gun.

Step 4: Start the process of changing the Storm window to the opening. Ensure the opening is pushed tightly to the top of the storm window.

Tightly lower the adjustable expand against the windowsill with a putty knife. See that the expansion also contacts around the bottom.
