We live in an old brick building and some of the apartments have moisture damage on the interior plaster walls. Some of it seems almost fungal.
One apartment owner believes the solution is to replace the internal plaster which he says is old and has lost its ability to asorb and pass through moisture that would naturally appear in the gap between the bricks and the interior wall.
Other owners believe the solution is to repoint the entire outside of the building to prevent moisture ingress.
As a condo owner I think I would favor the less expensive interior solution - what are your thoughts and advice on which solution is most appropriate?
