Hello, I'm new here though I have got many tips from reading the forums over the years.
I am hoping someone can give me the definite reasons why you should not drill holes into a cavity wall to ventilate a room.
Here is the thing - for many years there has been the smell of stale smoke, the stinky, illegal kind in much of my house. It comes from next door, no judgement, but I don't want it in my house, it's pretty strong and we just can't tolerate it anymore!
Turns out, in order to ventilate his son's room, next door dad drilled multiple holes into the front wall of his house below the window and stuck a vent over it. Although he says he drilled through both interior and exterior walls there is no sign of vent or holes on the outside. My conclusion, even if originally there were holes right through, they have since been painted over, we are talking small holes here.
We live in a semi - my theory is the smoke/smell fills up the cavity between our two homes and seeps through our floors.
Please explain in terms my neighbour can understand , why vents should be lined/ducted and can cause damp/cold and a breach into shared cavity space between the homes. He won't listen to me, maybe because I'm a woman!
