Leak under sash window

[AntonyE]

Hi,

I have a small leak coming in under a sash window. It only happens when it rains and only sometimes. I've redone the sealing under the window ledge outside, but that didn't help. So just looking for any ideas of things to try.

Attached photos ...
-- inside-window-ledge ... this is inside under the window ledge where the water is dripping in.
-- outside-main-view ... this is the window from the outside. The leak is on the left side as you look at the picture which you can't really see, but I couldn't get a view of that.
-- side-of-window ... this is what the window looks like from the side, but note that this is a different window (I can't get this view of the leaking window).
-- outside-close-view-1/2 ... these are photos of the leaking window on the corner that's leaking.

Any ideas much appreciated!

Unfortunately with leaks where the water is coming out isn't necessarily where it's getting in, it could be getting in right at the top and running down behind the leadwork and reappearing at the bottom, so difficult to diagnose from photos, you really need to be there in person and possibly strip stuff off to investigate

Thanks Crank ... I thought that might be the answer, I'll get someone to come and have a look. Thanks for the quick the response.
