I have and exterior steel door with magnetic seals along the sides and top. On the bottom the sill is capped with aluminum with a plastic channel threshold. I have replaced the door sweep seal on the bottom of the door and checked to ensure that the holes in the plactic channel are clear.
Whenever we get rain with wind on the face of the door water can be seen entering my house at the lower corners of the door. Things are worse when we have snow folowed by rain. Are there better seals I can get? Is there anything I can do except install a storm door? A Storm door would make it hard to get out when we do have snow.
