My friend on the Gulf Coast has a 14'th floor suite with a sliding patio
door facing the ocean. During last fall's hurricane the driving rain made
it through the door bottom (or sides) & caused water/mould damage in her
suite walls & carpet.
I noticed the door had a high 2" metal threshold on the inside which I guess
was meant to stop most water from coming in - but the outside
weatherstripping was the fuzzy stuff & was not super tight against the door.
The ...hurricane force... winds drove the rain right under the door.
Are there devices one can attach to the patio doors to prevent this?
What I was thinking of that might work is something that could be installed
that would snap tight against the door bottom (and sides) just as the door
is closed - and would snap away from the door when the door is opened. (if
they make such a thing that is).
Problem is - with her on the 14'th floor - whatever is installed has to
allow her to open & close the door from the inside.
I have photos of the existing door bottom.
