Leaking wall

Would painted it help in any way ? I was thinking of either re pointing it Or rendering it

Long shot - That vent grill might be the point of entry of the water. Putting a cowl over it would stop rain being driven in. Might even cut down on draughts in the room above the kitchen.

It looks like a poorly built wall, and there is probably no cavity tray above the window. There also is no slates overhanging the wall on the left hand verge. An exposed wall like that is always going to be a problem with driving rain.

Yes looks like the wall was not built properly. The vent on the side is for the cooker extractor . So don’t think that Is the issue . I was thinking of having the windows replaced but stopped as thought let’s get this leak issue sorted . Do you feel getting the new window fitted correctly with a cavity tray fix the problem. Or could the brick be letting in water

That left side verge has had flash bending done few days ago but leak still there .

Brickwork will allow moisture through. It runs down the inside of the external skin on a cavity wall and down to the bottom and out. When the cavity is bridged by a frame for example it needs a cavity tray to send the water out. If there isn't a tray it can come inside. Poorly built cavity walls often allow moisture through if there are mortar snots left on the inside and mortar on the wall ties, as well as half filled cross joints.

Sometimes silicone can fail to stick (It looks like the wall was once painted) or it just pulls away with movment, you may not see a gap unless you pull on it with a knife.  It will only cost £3? to be 100% sure its not that. The pointing looks fine, but may look different in person.

And that bin will be splashing rain on the wall and possibly making it damp.

Often the best way is to just stand out in heavy rain to watch where all the drips are going.

I noticed something yesterday it was dripping in from the top of the window as it was raining but then the rain had stopped for hours but it was still dripping but very very slowly . So looked like water was gathering somewhere.

Someone mentioned trying a hose pipe with a fine spray starting from the roof and working down and checking when the water is leaking. Any thoughts on that ?

If water is getting in to the cavity and pooling above the lintel, it will drip for hours or even days depending on how much water has collected. If that lump of stone above the window spans both the inner and outer leaf, then I'm not entirely convinced that that is where the water is coming from. I'd support the suggestion that it is the sealant above the window that needs looking at.
