We just had some sliding patio doors replaced with French Doors, but have noticed that after heavy rainfull there is quite a lot of water sitting at the bottom of the frames. To aid with my description I've put a picture here
Some water is obviously expecxted as there is a drain channel. However the area highlighted pink also fills with water and although there are gaps through to the drain gulley the water just tend to sit there. No water gets through the secondary seal to the inside of the house.
Is this normal with twin French doors? The amount of water getting through is quite surprising and I'm not sure if there will be any damaging effects if it sits there permanently. Should I get the installers back ?
Thankd for your input
