Hi Bob! September 08
It might not look very pretty but I have used Self-Adhesive Rubber Foam Weatherstrip on my garden patio doorstep and on the interior door frame up to a foot. This is because after torrential rain I once had water seeping under my patio door into my kitchen. I have only just applied it but it has worked!!! I chucked two full buckets of water and also sprayed water under the door. Eureka!! Not a sign of water on the inside or on the towels I had put down just in case! I bought this product from Robert Dyas. It is for all hinged doors and windows and for large gaps 5 to 8 mm. You can get strips for smaller gaps too. It comes in black and also white. I suggest that you try it on the underside of your front door so it can't be seen. Good Luck anyway!
