Double glazed door leaking at damp-course / sill interface.

Hello,

I have tried looking for my issue on the forum and can't find it, so I wonder if anybody can help. To begin, an image:
Attachment 3808

I have had to remove a large section of chip board flooring affected by the leak. Water is coming in immediately ABOVE the damp-course layer, i.e. just below the bottom white part (the sill?) and the water tracks along the damp course, where the water absorbs into wooden floor.

Our builder looked at it an said that it could be water being driven in from outside, under the sill, at the sill/brick interface. As such, he has comprehensively made a framing silicone bead, so stop water been driven through. But after a hard rainfall, with rain driven at the window, the leak is back!

Important to note here, is that water IS NOT seeping in at the line between the window frame and the top of the sill (as we look at picture in the inside) this joint is dry. The water is coming in above damp course layer, immediately below the bottom of the sill.. . . What could it be? I asked my builder if we should remove the glass pane and he said he couldn't see the benefit as leak is much lower down in door unit (somewhere).

The only clue I can see on forum is something to do with drain-away's, maybe the sill is full of water? Any guidance would be appreciated.

Thank you,

Paul.

Here's another couple of pics:
-There is no decking outside. The other picture shows that I have sealed around edge of window and under the window at frame/brick interface. I agree its a very odd place to leak, though any thoughts appreciated.
