Hello, I wonder if you can help. I've been in my house a number of years and been told from day 1 the doors are fitted correctly. My problem is, when it rains, they leak. I have a low level threshold (they say for wheelchair access - no one uses a wheelchair). The doors are UPVC inwards opening doors which catch on the floor. They cannot be highered anymore than what they are. If they were lowered to try and fill the gap, they wouldn't open. Here are the pictures.
TIA
