my front door leaks near the seal every time it rains. when the door was initially put in 3 yrs ago, it was well sealed at the entry area, and silicone under the seal was graciously applied. How ever the door still seems to have some leaking problems. I recently removed the molding around the door and sprayed door and window expandable foam all around it, then applied a large bead of silicone, ensureing all gaps were well filled. Then applied a rubber based sticky matting with silicone around all areas on the sides. Well it still leaks any help or products known that are great for leaking seals on doors would be gratefull. If there are any products great for sealing sills, please provide a name and possible means of procurement for the item. Ill try anything.
