I have an exterior door that leaks water into the house when rain is blown against it. The floor on the inside of the house is unfinished, meaning it is just the raw subfloor. I don't want to put the finish floor down until the leak is addressed.
The few things I have done thus far have not improved the situation but has also not made it worse.
Here is what I have done:
- Pulled the exterior frame off and filled all the gaps with slow expanding foam.
- I have put a roll of 4" valcor rubber strip over all the now foam filled gaps.
- I have checked and confirmed that the door is plumb.
- I installed a aluminum drip edge across the top molding and behind the clapboard.
- I inspected the gasket on the bottom and it looks ok.
- The surrounding gaskets seem ok (no cuts or overly squished look when the door is open).
I do not know the brand of door, but it is about 5 years old and has been doing this since pretty much the first storm after install.
What is the next thing I should look for OR what can I do to test and find what is failing to allow water to come in? And then, How do I fix it?
I will also say that depending on who I listen to from the DIY shows, Mike Holmes from Canada says "Use a storm door, that's why they call it a storm door". Norm Abrams from My USA says "an exterior door should keep out all the elements on its own and not require a storm door to do its job". I like and believe that an exterior door should do its job and something is wrong, broken or failing and THAT is what needs to be addressed.
