Wall vents - good or bad idea.

Wall vents - good or bad idea.

I have an old pre war house ( 1910 )

Had cement reponting at front, lime and cement mix on side and gypsum plater on walls in 2023 but see damp and mold at the corners of my living room walls and with the skirting boards all over the house.

I have a piv system in place due to poor ventilation and high humidity levels. I have trickel vents and open windows daily.

Damp specialist said he would install 2 vents in the living room would clear up the damp and mold as he believes it is all due to lack of ventilation than modern methods simpley don't work.

In my situation above does any one think vents will do any good or even make things worse? I have read a number of things that " ya they do wonders" and also " don't go never them they will make matters worse"

Any advise on vents please would be great

Many thanks

Tried a dehumidifier?
Get humidity under control first if it is high.

I’ve never seen wall vents being a recommended solution nowadays.

If you leave all the windows open you won't have damp issues. A stupid idea, but actually a similar solution to venting the cavities.

If there's damp, find the cause and eliminate it.
