Hi all
As you'll see from the picture below, we have crumbling paint on an internal wall, which my brother noticed when he painted over our bright green washable paint in 2015 with some emulsion (we've lived with it since then ). Before then we hadn't noticed anything. So the picture is of the boarded up chimney breast, and the tideline continues along the wall and in the other picture it shows how it is on the front of the breast also. We are in a terraced house and the neighbours haven't noticed anything on their side apparently but they do rent so not so much invested for them.
The house was damproofed - but we are talking probably 20 years ago.
Could this be rising damp or could it be something less difficult to tackle? I'd be grateful to have any input please!
By the way, the top of the chimney alcove isn't damp, it's unpainted board. And the right hand side seems to be only paint, whereas the back wall is like a lining paper and tapping on here sounds hollow. The dehumidifier is drawing water out.
Thanks everyone!
