Windows are usually sealed with expanding foam which prevents window leaking but if too little is used it can create channels of air between the wall and window which can lead to leaking. It is important that your installer accurately measures the aperture and installs windows which fit exactly.

The old caulk is located on the interstice between the frames and the wall, the frames and the windows, and where the windows meet one another.
