hi all, would you be able to help me out, I'm looking at a house built in the last couple of years and noticed some "ghosting", where you can see the outline of the blocks under the rendering? It's very pronounced on a house in the same row so I've taken a photo of that too, but the house I'm looking at seems to have it coming under two upstairs windows. There's also some white which I'm concerned may be rising damp? If anyone can give me an opinion I'd be v grateful. Does the ghosting indicate a moisture issue? Many thanks
