Water leaking in through door on main floor down to basement. My apologies if this isn't the right section to be posting this in. I have a leak which is letting water come in under my door on the main floor of my house. I usually place a towel at the bottom of the door and it appears both ends of the towel are the most damp after a hard rain. On very windy and raining days it will leak so much that it penetrates down through the floor into my basement (Nothing major but the water leak is very apparent). I found out this was happening because I noticed that small pools of water were building up inside the plastic covering containing the insulation for the interior walls, it just happens it was directly below where the water was coming in from under the door on the main level. The water had made its way through the floor and was dripping through my insulation eventually resting on the plastic covering. I first thought this was entirely due to the water entering the house under the main floor door, but as a trail and error experiment I taped up one side on the the outside of the door between the vinyl siding and the left side of the door. The leak seemed to have stopped. So now I'm in major panic mode because water is coming inside from what I think is under the door and now it seems to be entering the basement through the floor somewhere outside between the vinyl and left side of the door. Is this fixable without getting some contractor in to take a look? Would this be considered structural? I will add pictures tomorrow in my attempt to better explain what is happening and where the water is coming in. Any advice or suggestions would be greatly appreciated!! Thanks!
