My window is sad!

[Ian Geary]

My window has got a case of the winter blues, and is crying to itself

Ok, we've got really strong wind and rain at the moment, so rain is obviously getting in.

The upvc double glazing is probably 25 years old now, but has been leak free for the last 15 years with us.

Outside, the top of the window is somewhat shielded by an overhang of tiles.



So water is not directly landing on that bit of the window.


I think rain must be getting through the hanging tiles,





then landing on top of the window internally, and making it's way through the join within the upcoming sections


So would be right in thinking this is a window out job?

Thanks

Wouldn’t you take the tiles off first? Might need the membrane renewing.

The lead cover flashing at the top of the tiles does not come down far enough, so it s not covering the perp of the course below.
Wind driven will get behind, but without knowing the detail at the window head, hard to be sure.

Agree with both the above. The window is unlikely to be the issue, water is travelling down until it meets the window then ingressing at the aperture.
Find where the point is that the water first gets in, as Aluminati says, that could well be the top line of tiles, just underneath the upper windows cill.

Assuming you do it yourself, at low cost, you could consider applying sticky flashband across the upper part of the top line of tiles as a temporary solution / eliminate that as the cause.

I recently had significant water ingress when we had an unusually strong Northerly wind driving heavy rain into our bedroom window. A small amount of mastic has solved it for the medium term until I get the root cause eliminated next year ( a windows out job to replace the cill).
