UPVC French door water drainage problem

So it would appear that the manufacturing company have provided the French doors for the Juliet balcony with concealed/bottom drainage holes instead of face drainage holes despite the fact that they knew it was for a Juliet balcony with no seal.

The water gets blocked inside The trim overflows and ends up in the house and doesn’t drain away outside.

How can I rectify this problem? Can I simply fill in these drainage holes with sealant and drill some new ones to the outside face?

Manufacturers are being incredibly unhelpful and unresponsive, the frame profile is Rehau.

Any advice or pointers on how I can rectify this without removing them would be much appreciated.

The door frame needs to come out and the concealed drainage sealing up, only then will it start to face drain, how come theres a face drain cap in the centre if they've put concealed drainage in?
Are you sure is concealed drainage?
I’d start by putting a drainage slot like the one in the middle to each end.
Are the screws sealed? Water may be entering down through this point
External drips to the door sashes will help reduce the water ending up in the profile
Lastly if the bottom frame is tilting backwards slightly, this can cause the overflow
Hi guys thanks for your reply no I’m not 100% sure that there is concealed drainage but when I spoke to the manufacturers they seem to think that’s what they had put on it, the Guy I spoke to didn’t seem to know much.

No the screws aren’t seals although they are all dry I will put some blobs of silicone over the heads of the screws just in case.

I just checked The frame now with a spirit level and it all seems to be perfectly plumb on all sides.

I guess the best bet then is to add two additional face trains on either ends adding three in total along the outside bottom and hopefully that may do the trick....?

The issue with the screws is the chamber below the screw head. If the water drains down through the drainage holes in the top of the profile, there’s a good chance water will trickle down the screw and make its way in.
This is the part you don’t see or can get to, ideally the screws need to come out and you need to get sealant into the hole further down, then put the screw back in
Thanks a lot for the advice as drilling those extra holes has managed to get the water flowing freely! J
I see what you mean in regards to the screws I will have to take one out and see whether they did or not I’m guessing they probably didn’t and if not will squeeze a generous amount of silicone down the screw and as deep as I can in the hole and re-fasten, do you mean just the screws along the top and bottom of the frame? Or the side ones as well?
