Our house on the South Coast NSW has a mould problem.
Mould grows on the venetian blinds, on leather lounge, on paper in frames, walls.
It's a brick veneer house on brick piers, on a slope.
There are some vents visible on the outside.
Windows are often open and there is decent airflow in main living areas.
Faces North, so reasonable amount of sun.
I'm a total newbie to house maintenance, building etc.
Where should I start looking for a solution?
Thanks.
