How to avoid Water Leaking through Airlite Windows

[Rose Martin]

I have Airlite Windows throughout my house remodeled in the last 3 months. I discover that continually in huge rainfall, with windows closed firmly that water penetrates through the joint in the frame built of aluminum. While in many circumstances this results of waters collecting right exactly in corner of the frames, in huge rain when too much water gathers, this results to dripping from our frame down to our walls.

I am interested if how would you guys fixed this kind of issue without contacting any repair companies.
