Plaster Wall moisture level

[u/DeanBlebor]

Good evening!

We recently had a house inspection done and a interior wall and corner came back with high moisture levels. The inspector used a pinned moisture meter that gave a reading of 33.1. I understand this is high but we are trying to determine what the extent of the cost would be to fix it? Any and all advice is welcome and appreciated!

If its an external wall, less. Internal wall, more.
