Penetrating Damp
Discussion
Seem to have some damp forming midway up a solid (non-cavity) wall as per images below. Not sure how it's getting in. Assume there's a crack in the mortar, but can't inspect due to the render and no evidence of it leaking in from above.
Not sure how best to deal with it? Stormdry seems well reviewed, but suggests it's unsuitable for application to painted render.
Would rather avoid having to remove all the render and repair, but letting it dry out them cladding may be an option?
Any advice?

Can you provide a clearer picture of the front elevation, from the area where the damp is up to the top of the gable.
What age is the house - from appearance, it looks unlikely to be a solid wall.

I'm no expert, but AFAIK, most post war housing is cavity wall.
But that first picture looks like it might not be a block or brick wall, my parents had a 60s house where the end walls were originally wood clad panels, the nover time people faffed with them.
The windows look not to be inset into the wall as per normal?
Personally, I'd chop a hole in the wall inside and see what's going on. A more sophisticated bodger might make a small hole and look with an endoscope.
The vege/soffit WHY vertically above the wet spot looks dodgy in the first photo.
I'd guess water is running down the outer leaf of the wall and tracking across some sort of bridge where the wet spot is. Traditionally the bridge is either a wall tie with mortar on it, or a dead animal in the cavity, but many variations are possible.
The water could be entering the wall t the top of the window and finding its way across.

Based on the gable end and the information provided when I bought the house, it's solid.But that first picture looks like it might not be a block or brick wall, my parents had a 60s house where the end walls were originally wood clad panels, the nover time people faffed with them.

I’d start at the top - what’s going on with the facia boards? If you’ve water pissing in behind the render from the top of the wall then I’m not surprised you have issues on the inside.
Sorry, that was an old pic from Google and it's just where the images aren't aligned properly.They look fine in reality.
