Hi all- after some heavy, sideways rain, we noticed the carpet in front of these sliding doors was wet.
I sprayed the sliding doors from the outside with the hose and noticed water entered when I sprayed the bottom of the sliding door.
Inside the house, a timber panel sits between the bottom of the sliding door and the slab. The water is entering directly under the timber panel I.e. it doesn't appear to be entering directly under the door and the top of the timber panel is dry (blue section of second pic. Third picture shows the timber panel).
Any ideas what the issue could be and/or whether this is a DIY job or who i should contact (sliding door repairer, general handyman....?)
