Your logic is undeniable. Before the builder stormed out of my house (which I'm not sure how much was hurt feelings and how much was being a drama queen for intimidation), he kept insisting that he has been doing things this way for 30 years. What he failed to recognize and what you have stated succinctly: my door is leaking and leaking badly and leaking now for 9 months. I don't care what you have done for 30 years---there's a wet door and a wet basement floor because of it! Not to mention two (2) wet spots on my basement walls. Thanks.
