I think this wall may have rising damp (see pics). Internal floor is wood, walls are brick, internal original plaster that's been skimmed at some point; external walls are rendered/pebble-dashed.
The plaster had blown in some spots. Hacking off showed plaster base coat was darker in places, maybe damp up to about 2 foot. Top coat didn't take much persuading to come away. The skirting board seemed fine, no sign of damp. Some white powdery stuff on bricks.
Can anybody advise on best way forward. Should I tank then replanted this wall or could this be more serious?
