Hi it might be worth checking the drainage at the bottom of your doors. When it rains water goes down through the gap between your window and rubber and should drain outwards at the bottom of your door. If you look underneath your door you should see some kind of drainage holes which do tend to get blocked up in winter by dirt and leaves. Just something might be worth a look at. Good luck.
