Hey all, hope you're well
When I bought the house 5 years ago I drilled through the inner cavity wall and added trickle vents at old fireplaces.
I don't think it's made any difference other than blasting cold air from within the cavity into bedrooms and i want to seal them up as they were before.
I presume I could just use foam. But is there some other way to ensure I don't fill the cavity with gunge? The holes aren't massive, maybe 3 x 5 inches. Would you use sand and cement or something? And then I'll skim the hole in the plaster.
Hope I'm making some sense. Skill level low.
