Evening,
Have an 1870 terrace in Sydney with some dampness / condensation issues on an internal wall.
After a lot of reading I have come to conclusion that it is due to condensation
- external wall rendered
- no vents external or internal
- concrete slab with floorboards a few cm above
Is it worthwhile trying to get ventilation into this very narrow gap between slab and floorboards?
Thoughts on air brick internally?
Any other tips?
Thanks π
