My laundry room is in a finished porch with a door to the outside. Previously we had insulation added underneath the floor of the room, because it hurt to walk in there in the winter. The floor is better now, but the room still gets very cold. You can feel outside air coming in between the door and the doorframe - with the storm door in place. I tried weatherstripping the door, but that made it so it didn't close at all and actually made the leak worse. It turns out the door and doorframe just don't fit together very well and no amount of weatherstripping will fix it. Questions:
1. Is the best solution to replace it with a prehung, insulated exterior door?
2. Is there a guide to adjusting doors so they sit in the frame better?
