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

The mould triangle consists of heating, ventilation and insulation. Leave one out and you'll be catching your own tail.

It would be beneficial if you insulated your walls from the inside. If not you can also insulate from the outside.

Adding vents would be a good idea. You can hire a hole saw to make a 3 inch gap for the vents or you can just get the person in to do it for you.

You should be heating your house properly and reducing humidity. Glad to see you got a PIV system.
