Hello, I’m having issue with my kitchen floor next to the back door. When it rains or snows, sometimes water gets tracked in. The floor is starting to get soft. I’m replacing my floor this weekend and William Ben fixing the subfloor where it’s soft. My question is, is there anything I can do, short of applying some sort of silicone across the door edge that will help keep the water from seeping between the door and the floor? The floor I’m Putting in a vinyl plank so it’s waterproof.
