Where would you reckon water was getting in on our window?

[Mr. Clueless]

First off I did the vertical silicone that's just & so in shot over on the right of that thumbnail. It was ok up at the top but to the bottom it had started coming away from the frame. To my surprise this was really quite dry. In fact not quite dry, it was just dry-dry as dry could be.

Although that wasn't where water was getting in on the inside at the start of the year - it was from above the window openers.

The silicone had started to look gapped in the horizontal channel in the thumbnail and when I dug the silicone out this was actually very wet - so getting closer to the cause of how water is making its way inside.

Initially I thought it was probably just getting in behind the (10-11yr) old silicone & tracking inside.

But then I noticed this...



And wondered whether water was getting in at that cracked cement area, running in over that plastic strip & getting inside that way.

Although that 2nd thumbnail is obviously from the centre of the window & it most certainly wasn't leaking in the centre - it was leaking right over the window opener that you can see in the first thumbnail.

I'm hoping nobody is going to be telling me I need to re-render the whole house front to back! But yeah, purely off the photos would you reckon the silicone or the cement would be the cause of the water getting inside? And if the cement, what am I to do there? Brush some water proofer on? Run some clear silicone along it? Probably a no & no but I don't have a clue tbh.

Nothing to cast off rain above window , should have detail like this .

So you're saying there should've been something installed at the top? So a top ledge in addition to a bottom ledge kind of thing?

Or am I getting the wrong end of your stick?

Even if so....we moved in in 2015 & this winter gone is the first time it's ever leaked there. Could be coincidence I suppose but that says to me that something has recently changed to allow that to happen. Now whether that something is a) the silicone breaking down in the OP image b) the crack in the cement work in the OP image c) a combination of those or d) something else entirely, I'm just an idiot & have absolutely no clue, which is why I'm here.

I would've just thought that if it's purely down to it having no top ledge & no other reason then surely it should've happened at least once in the 10 years that have passed because we've had plenty of driving rain over that time.
