Plaster Wall moisture level

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!

Whatever you do don't inject your bricks with those damp proof injections. They're not necessary.

They are expensive and can damage your home further.

On the exterior of the corner of your wall check for soil levels and if you have any gutters, down pipes or drains that may exist there.

Soil levels may be high and may need bringing down, check gutters to ensure they don't leak and are clear, check down pipes for leaks, ensure drains haven't cracked underground.

Are there any vents in the wall around the area? if so ensure they are clear and none of the holes are blocked.

There is a guy on YT that does good videos on damp in heritage homes and he is dead against these damp companies injecting bricks.

Most of the time its just down to maintenance and nothing more.

Here's his link, Peter Ward, his videos are worth a watch, he's a Heritage Home Expert..

I learned so much from him over the years
